Forgot one relevant package: $ emerge -pqv '=sci-libs/libsigrokdecode-0.5.3::gentoo' [ebuild R ] sci-libs/libsigrokdecode-0.5.3 USE="-static-libs" PYTHON_SINGLE_TARGET="python3_9 -python3_8"
Created attachment 713985 [details] libsigrokdecode build.log Enabling USE=python in libsigrok doesn't seem to solve it, removing all three packages and rebuilding them doesn't solve it, and disabling -flto in all three packages and rebuilding them doesn't solve it either. Adding libsigrokdecode's build.log for completeness.
I've tested building this in a clean (no LTO, -O2) Gentoo Prefix. As long as python3.8 is installed when libsigrokdecode is built, it works, even when python_targets_python3.8 is not set and python_targets_python3.9 is set. Uninstalling python3.8 causes this same error to pop up. I don't think libsigrokdecode picks the python version properly. See the end of the configure output, where it falls through all the python tests.
Created attachment 714042 [details] Fixed libsigrokdecode-0.5.3.ebuild I've figured it out. The problem exists in sci-libs/libsigrokdecode, and is twofold: - The configure script picks the highest available version of python regardless of whatever version is picked by the python eclass - python3.9 isn't supported by the configure script, so the nearest fallback is the python3 pkg-config module. Since python3.8, to pass the -lpython3 flag, you need to use the python3-embed module instead. Only python3.8-embed is detected by the configure script, but that doesn't exist. Since the python eclass creates symlinks for the required pkg-config modules, and the configure script provides no method of forcing the used module, the easiest way to fix this is to make sure the "generic" module names are tried first, for example, in src_prepare(): sed -i -e 's/\[SRD_PKGLIBS\],$/& [python3-embed], [python3],/' configure.ac eautoreconf This should work for python3.8+ and python3.7-. The python interpreter is picked up by the PYTHON3 environment variable, instead of just python, so setting PYTHON3="${PYTHON}" for the econf call is appropriate. I've attached a fixed ebuild.

Would you mind attaching your GCO signoff (Signed-off-by: Real Name <email>) so I can commit this as-is? (Even better would be a git am-able patch, but not required.)
