Compiling dev-util/mdds-1.6.0 fails in the configure phase if gcc was built with USE=-openmp. It does work after rebuilding gcc with USE=openmp. I could reproduce the issue on three different (but similarly configured) Gentoo systems. The crucial part from config.log seems to be the following: configure:2728: checking whether the C++ compiler works configure:2750: x86_64-pc-linux-gnu-g++ -O2 -march=native -pipe -Wshadow -std=c++11 -fopenmp -Wall -g -pedantic-errors -I/usr/include -I/usr/local/include -Wl,-O1 -Wl,--as-needed -fopenmp conftest.cpp >&5 x86_64-pc-linux-gnu-g++: fatal error: cannot read spec file 'libgomp.spec': No such file or directory compilation terminated. Indeed, /usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/libgomp.spec does not exist on my system if gcc is built with USE=-openmp. Reproducible: Always Steps to Reproduce: 1. USE=-openmp emerge gcc:9.3.0 2. emerge =dev-util/mdds-1.6.0 Actual Results: >>> Configuring source in /var/tmp/portage/dev-util/mdds-1.6.0/work/mdds-1.6.0 ... ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/mdds-1.6.0 --htmldir=/usr/share/doc/mdds-1.6.0/html --libdir=/usr/lib64 --disable-docs --disable-memory_tests checking for a BSD-compatible install... /usr/lib/portage/python3.7/ebuild-helpers/xattr/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking whether to enable maintainer-specific portions of Makefiles... no checking for x86_64-pc-linux-gnu-g++... x86_64-pc-linux-gnu-g++ checking whether the C++ compiler works... no configure: error: in `/var/tmp/portage/dev-util/mdds-1.6.0/work/mdds-1.6.0': configure: error: C++ compiler cannot create executables See `config.log' for more details Expected Results: The package configures and compiles successfully without openmp support or depends on gcc with the openmp USE flag.
