Created attachment 923384 [details] 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. build.log: ``` * Package: dev-libs/imath-3.1.12:3/29 * Repository: gentoo * Maintainer: negril.nx+gentoo@gmail.com proxy-maint@gentoo.org * USE: abi_x86_64 amd64 elibc_glibc kernel_linux python python_single_target_python3_12 test * FEATURES: installsources network-sandbox nostrip preserve-libs sandbox test userpriv usersandbox * Using python3.12 to build >>> Unpacking source... >>> Unpacking imath-3.1.12.tar.gz to /var/tmp/portage/dev-libs/imath-3.1.12/work >>> Source unpacked in /var/tmp/portage/dev-libs/imath-3.1.12/work >>> Preparing source in /var/tmp/portage/dev-libs/imath-3.1.12/work/Imath-3.1.12 ... * Source directory (CMAKE_USE_DIR): "/var/tmp/portage/dev-libs/imath-3.1.12/work/Imath-3.1.12" * Build directory (BUILD_DIR): "/var/tmp/portage/dev-libs/imath-3.1.12/work/Imath-3.1.12_build" * Applying imath-3.1.11-fix_cmake_module_export.patch ...

It is because of my boost.
for unknown reason, in the failed CMakeLists.txt : ``` Python3_VERSION_MAJOR.Python3_VERSION_MINOR 3.12 Python_VERSION_MAJOR.Python_VERSION_MINOR: 3.13 ```
this line triggers change: in src/python/CMakeLists.txt: ``` find_package(Boost OPTIONAL_COMPONENTS python python${Python_VERSION_MAJOR} ${PYIMATH_BOOST_PY_COMPONENT}) ```
It seems I found the reason.
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
(In reply to Arniiiii from comment #5) > > This is fixable by adding -DPython_EXECUTABLE=/usr/bin/python3.12 Can gentoo's ebuild be "fixed" in ::gentoo ?
