emerge --info

I have python3 from 3.10 to 3.13 installed.

imath is emerged with 3.12.

Also: *my* boost is installed ( not ::gentoo but ::ex_repo , it's boost build by cmake ), but I'm not sure if that's the problem right here.

[Comment 1 Arniiiii 2025-04-01 12:44:35 UTC]

It is because of my boost.

[Comment 2 Arniiiii 2025-04-01 12:54:35 UTC]

for unknown reason, in the failed CMakeLists.txt :

```
Python3_VERSION_MAJOR.Python3_VERSION_MINOR 3.12 Python_VERSION_MAJOR.Python_VERSION_MINOR: 3.13
```

[Comment 3 Arniiiii 2025-04-01 13:07:06 UTC]

this line triggers change:

in src/python/CMakeLists.txt:
```
find_package(Boost OPTIONAL_COMPONENTS
  python
  python${Python_VERSION_MAJOR}
  ${PYIMATH_BOOST_PY_COMPONENT})
```

[Comment 4 Arniiiii 2025-04-01 13:36:17 UTC]

It seems I found the reason.

[Comment 5 Arniiiii 2025-04-01 13:37:40 UTC]

in boost created by cmake:

in /usr/lib64/cmake/boost_python312-1.88.0-static/boost_python312-config.cmake :
```
find_dependency(Python COMPONENTS  Development)
```

This is fixable by adding -DPython_EXECUTABLE=/usr/bin/python3.12

Can gentoo's ebuild be "fixed" in ::gentoo ?
