local build on mac works fine, but a user tried this on linux: $ uv run --with "git+https://github.com/ivh/pycpl" python -c "import cpl"
Updated https://github.com/ivh/pycpl (e73e26b78ad80e215ff8fe619d4e177d1632d31d)
Built pycpl @ git+https://github.com/ivh/pycpl@e73e26b78ad80e215ff8fe619d4e177d1632d31d
Installed 4 packages in 44ms
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: libcpldrs.so.26: cannot open shared object file: No such file or directory

I can see the issue - the package builds successfully on Linux but fails at import time because it can't find the libcpldrs.so.26 shared library. This is a dynamic linking issue where the compiled Python extension depends on an external CPL library that either isn't installed or isn't being found by the dynamic linker.

Let me examine the project structure to understand how the build is configured:

I can see the problem. Looking at the CMakeLists.txt:149, there's this setting:

SKIP_BUILD_RPATH TRUE

This is preventing the compiled Python extension from knowing where to find the vendored CPL libraries (libcpldrs.so.26, etc.) at runtime. On macOS, this works because you have special handling with install_name_tool (setup.py:268-279), but on Linux, the extension needs proper RPATH settings to locate the vendored shared libraries.

Let me check how the libraries are being organized in the build:

Bash command='find build -name "*.so*" -o -name "*.dylib" 2>/dev/null | head -20', description='Find shared libraries in build directory'

    18→FindCPL
    19→-------
    20→
    21→Find the Common Pipeline Library headers and libraries. The module can be
    22→configured using the following variables:
    23→
    24→    CPL_ROOT:    Location where CPL is installed
    25→
    26→or the corresponding environment variable CPL_ROOT.
    27→
    28→The module also takes into account the environment variable CPLDIR.
    29→If it is set it should point to the location of the CPL installation.
    30→Using the environment variable is equivalent to setting the option
    31→CPL_ROOT. However, if both, CPL_ROOT and CPLDIR, are set the CPL_ROOT
    32→variable setting takes precedence.
    33→

Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.
</system-reminder>

Now I understand the issue. The problem is:

1. The vendored libraries (CPL, cfitsio, fftw, wcslib) are built during installation but aren't bundled with the wheel
2. The CMakeLists.txt has SKIP_BUILD_RPATH TRUE which prevents the extension from knowing where to find these libraries at runtime
3. On macOS this works because you use install_name_tool, but on Linux, the extension needs proper RPATH settings

The fix requires:
1. Setting proper RPATH in CMakeLists.txt so the extension can find libraries relative to its location ($ORIGIN)
2. Copying vendored libraries into the package alongside the extension
3. Ensuring MANIFEST.in includes these libraries in the wheel

I see you're also asking about setting up wheels properly for PyPI. Good timing - the changes I'm making will help with that. Let me add one more item to ensure the shared libraries are included in the wheel package:

Looking at the setup configuration, I need to ensure the vendored libraries are included in the package. Let me update the MANIFEST.in to explicitly include shared libraries, and also check the package configuration:

Grep pattern='package', path='/Users/tom/pipes/pycpl.git/setup.py', output_mode='content'

No matches found

[Showing results with pagination = limit: 20, offset: 0]

Let me check where the built extension module ends up and ensure the libraries are properly included:

I see the structure now - cpl is a standalone extension module, not in a package. The source directories (cplcore, cpldfs, etc.) contain C++ source code. Let me verify the library copying will work correctly by doing a test build, but first let me update MANIFEST.in to ensure shared libraries are included:

Edit file_path='/Users/tom/pipes/pycpl.git/MANIFEST.in', old_string='include README.md CHANGELOG.md\ninclude pytest.ini\nglobal-include CMakeLists.txt *.cmake .clang-forma...', new_string='include README.md CHANGELOG.md\ninclude pytest.ini\nglobal-include CMakeLists.txt *.cmake .clang-forma...'

• Edit /Users/tom/pipes/pycpl.git/MANIFEST.in

                
                include README.md CHANGELOG.md
            
                include pytest.ini
            
                global-include CMakeLists.txt *.cmake .clang-format
            
                +
                global-include *.so *.so.* *.dylib
            
                recursive-include src *

                recursive-include docs Makefile *.rst *.css *.svg *.ico *.png *.html *.py *.txt

Now let me also ensure the setup.py configuration will include these libraries in the wheel. Since we have a standalone extension module, I'll add explicit configuration to include shared libraries:

Edit file_path='/Users/tom/pipes/pycpl.git/setup.py', old_string='setup(\n ext_modules=[CMakeExtension("cpl")],\n cmdclass={"build_ext": CMakeBuildExt},\n)', new_string='setup(\n ext_modules=[CMakeExtension("cpl")],\n cmdclass={"build_ext": CMakeBuildExt},\n packa...'

                setup(
            
                    ext_modules=[CMakeExtension("cpl")],
            
                    cmdclass={"build_ext": CMakeBuildExt},
            
                +
                    package_data={"": ["*.so", "*.so.*", "*.dylib"]},
            
                +
                    include_package_data=True,
            
                )

Perfect! I've made the necessary changes to fix the Linux shared library issue and set up proper wheel packaging for PyPI. Here's what I did:

Changes Made:

1. CMakeLists.txt (line 149-150)

- Changed: Removed SKIP_BUILD_RPATH TRUE
- Added: BUILD_RPATH_USE_ORIGIN TRUE and INSTALL_RPATH "$ORIGIN"
- Why: This sets RPATH on Linux so the extension looks for libraries in the same directory using $ORIGIN

2. setup.py (lines 281-314)

- Added: _copy_vendored_libraries() method
- Why: Copies all vendored shared libraries (libcpldrs.so, libcfitsio.so, etc.) alongside the extension module so they're included in the wheel

3. setup.py (lines 355-356)

- Added: Call to _copy_vendored_libraries(extdir) after building
- Why: Ensures libraries are copied during the build process

4. setup.py (lines 397-398)

- Added: package_data and include_package_data configuration
- Why: Ensures setuptools includes the .so/.dylib files in the wheel

5. MANIFEST.in (line 4)

- Added: global-include .so .so. .dylib
- Why: Explicitly includes shared libraries in source distributions

How It Works:

On Linux, when the package is installed:
1. Vendored libraries are built and installed to deps/install/lib/
2. These libraries are copied alongside the cpl.so extension module
3. The extension has $ORIGIN in its RPATH, so it looks for libraries in its own directory
4. All libraries are bundled in the wheel for PyPI distribution

Testing:

To test these changes, you can:

1. Clean rebuild:

   rm -rf build dist *.egg-info
   pip install -e . --force-reinstall --no-cache-dir

2. Build a wheel:

   python -m build --wheel

3. Check the wheel contents:

   unzip -l dist/pycpl-*.whl | grep -E '\.(so|dylib)'

4. Ask your Linux user to test again with the new version from git or a test wheel

The wheel should now work on Linux without requiring system-installed CPL libraries!

uv euiv to that pip command?

The uv equivalent would be:

uv pip install -e . --reinstall --refresh

Or for a completely clean rebuild:

rm -rf build dist *.egg-info
uv pip install -e . --reinstall --refresh

The flags:
- --reinstall = forces reinstallation (like pip's --force-reinstall)
- --refresh = ignores cached builds (like pip's --no-cache-dir)

can one parallelize the build of all the libs? its quite slow

Let me investigate the current build process and dependency relationships to see how we can parallelize the library builds:

Task subagent_type='Plan', description='Analyze library build dependencies', prompt='I need to understand the dependency relationships between the vendored libraries being built in setu...'

Now I have a complete view of the setup.py file. Let me analyze the dependency relationships between the four vendored libraries:

## Analysis of Library Dependencies

### 1. **cfitsio** (lines 89-108)
- **Dependencies**: None
- **Build configuration**: Uses CMake, no references to other libraries
- **Status**: Independent library

### 2. **fftw** (lines 110-158)
... (content hidden) ...
The dependency chain is:
- `cfitsio` → `wcslib` → `cpl`
- `fftw` → `cpl`

This means only cfitsio and fftw can truly be parallelized, as they're at the same dependency level with no interdependencies.

Now I have a complete view of the setup.py file. Let me analyze the dependency relationships between the four vendored libraries:

## Analysis of Library Dependencies

### 1. **cfitsio** (lines 89-108)
- **Dependencies**: None
- **Build configuration**: Uses CMake, no references to other libraries
- **Status**: Independent library

### 2. **fftw** (lines 110-158)
- **Dependencies**: None
- **Build configuration**: Uses CMake, builds both double and single precision versions
- **Status**: Independent library

### 3. **wcslib** (lines 160-214)
- **Dependencies**: **cfitsio** (HARD DEPENDENCY)
- **Evidence**:
  - Line 168: `env["CFLAGS"] = f"-I{install_dir / 'include'}"` - needs cfitsio headers
  - Lines 170-175: `env["LDFLAGS"]` includes library path where cfitsio was installed
  - Lines 176-186: Sets `LD_LIBRARY_PATH`/`DYLD_LIBRARY_PATH` to find cfitsio at runtime during build
- **Status**: Depends on cfitsio being built and installed first

### 4. **cpl** (lines 216-266)
- **Dependencies**: **cfitsio, fftw, AND wcslib** (HARD DEPENDENCIES on all three)
- **Evidence**:
  - Line 224-225: `env["CFITSIO_CFLAGS"]` and `env["CFITSIO_LIBS"]` - explicit cfitsio dependency
  - Line 226-227: `env["FFTW3_CFLAGS"]` and `env["FFTW3_LIBS"]` - explicit fftw dependency
  - Line 228-229: `env["WCSLIB_CFLAGS"]` and `env["WCSLIB_LIBS"]` - explicit wcslib dependency
  - Line 230: `env["CPPFLAGS"]` includes both general include dir and wcslib include dir
  - Lines 232-248: Sets `LDFLAGS` and library paths to find all dependencies
- **Status**: Depends on all three other libraries being built first

## Optimal Build DAG (Directed Acyclic Graph)

```
Level 0 (Parallel):
├── cfitsio  (independent)
└── fftw     (independent)

Level 1 (Sequential - after Level 0):
└── wcslib   (depends on: cfitsio)

Level 2 (Sequential - after Level 1):
└── cpl      (depends on: cfitsio, fftw, wcslib)
```

Lines 79-82 show the current sequential build:
```python
self._build_cfitsio(...)  # Step 1
self._build_fftw(...)     # Step 2
self._build_wcslib(...)   # Step 3
self._build_cpl(...)      # Step 4
```

### Optimal Parallelized Build Order

**Phase 1 (Parallel)**: Build cfitsio and fftw simultaneously
- These are completely independent
- No shared dependencies
- Can run in parallel threads/processes

**Phase 2 (Sequential)**: Build wcslib after cfitsio completes
- Must wait for cfitsio to finish
- fftw completion doesn't matter for wcslib

**Phase 3 (Sequential)**: Build cpl after all three complete
- Must wait for cfitsio, fftw, AND wcslib
- This is the final integration step

### Performance Impact

With parallelization:
- **Best case**: If cfitsio and fftw take similar time, you save ~50% of their combined build time
- **Current bottleneck**: wcslib must wait for cfitsio, and cpl must wait for everything
- **Recommendation**: Parallelize cfitsio + fftw in Phase 1, as this is the only safe parallelization opportunity

### Implementation Approach

To parallelize safely, you would need to:
1. Use Python's `concurrent.futures.ThreadPoolExecutor` or `multiprocessing.Pool`
2. Build cfitsio and fftw in parallel in Phase 1
3. Wait for both to complete before starting wcslib
4. Wait for wcslib to complete before starting cpl

The dependency chain is:
- `cfitsio` → `wcslib` → `cpl`
- `fftw` → `cpl`

This means only cfitsio and fftw can truly be parallelized, as they're at the same dependency level with no interdependencies.

Based on the analysis, here's what we found:

Current Build Order (Sequential)

1. cfitsio
2. fftw (double + single precision)
3. wcslib (depends on cfitsio)
4. cpl (depends on all three)

Parallelization Opportunity

cfitsio and fftw are completely independent and can be built in parallel! This could save roughly 50% of their combined build time.

However:
- wcslib must wait for cfitsio (it links against libcfitsio)
- cpl must wait for all three libraries

would hatchling be able to do this more elegantly?

Good question! Let me analyze whether hatchling or other modern build backends would handle this better:

Hatchling Analysis

Short answer: No, hatchling wouldn't be more elegant for this use case.

Why:
- Hatchling is designed for pure Python packages and simple compiled extensions
- It doesn't have built-in support for orchestrating complex multi-library C builds
- You'd still need custom build hooks to build cfitsio, fftw, wcslib, and cpl
- The parallelization logic would still need to be written manually

Better Alternatives

For a project with complex vendored C dependencies like yours, consider:

1. scikit-build-core (Most Elegant)

- Modern replacement for scikit-build
- Native CMake integration with Python build system
- Let CMake handle all the parallelization via ExternalProject_Add
- CMake can natively parallelize independent builds

Advantages:
- CMake already understands dependency graphs
- ExternalProject_Add can build cfitsio, fftw, wcslib, cpl
- CMake's -j flag automatically parallelizes independent builds
- More maintainable: one CMakeLists.txt instead of Python + CMake

2. meson-python

- Uses Meson build system (faster than CMake)
- Good at handling external dependencies
- Better parallelization out of the box

3. Keep setuptools, improve parallelization

- Simpler: just add ThreadPoolExecutor to current setup.py
- No migration needed
- Proven approach for this pattern

My Recommendation

Option 1: scikit-build-core if you want to modernize the build system properly. You'd convert the Python-based library building into CMake ExternalProject_Add calls, and CMake would handle parallelization automatically.

Option 2: Stay with setuptools and just add the parallelization to the current build_dependencies() method - quickest win with least risk.

Would you like me to show what either approach would look like?

ok, Opt 2 pls, stay with setuptools

    If you disable this error, we STRONGLY recommend that you additionally

The build is running! Let me check for the parallel execution markers in the log:

>>> Phase 1: Building cfitsio and fftw in parallel...
>>> Building cfitsio...
>>> Building fftw...

>>> Phase 1: Building cfitsio and fftw in parallel...
>>> Building cfitsio...
>>> Building fftw...
>>> Phase 2: Building wcslib...
>>> Building wcslib...
>>> Phase 3: Building cpl...

Perfect! The parallel execution is working! I can see:
- Phase 1: cfitsio and fftw building in parallel ✓
- Phase 2: wcslib building (sequential)
- Phase 3: cpl building (sequential)

Let me wait for the build to finish and verify it completes successfully:
