Description Alexey Edelev 2020-11-11 13:01:20 UTC
dev-lang/spidermonkey-78.4.0 build fails because of CXXFLAGS="${CFLAGS} -std=c++14" are installed system wide.

If I build dev-lang/spidermonkey-78.4.0 with c++14 enabled system wide, I observe issue. 

dev-lang/spidermonkey-78.4.0 add -std=gnu++17 flag, but it's overwritten by CXXFLAGS from /etc/portage/make.conf

Compilation command looks as bellow:
/usr/bin/x86_64-pc-linux-gnu-g++ -std=gnu++17 -o special-case.o -c  -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/build/dist/system_wrappers -include /var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/firefox-78.4.0/config/gcc_hidden.h -fstack-protector-strong -DNDEBUG=1 -DTRIMMED=1 -DWASM_SUPPORTS_HUGE_MEMORY -DEXPORT_JS_API -DMOZ_HAS_MOZGLUE -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/firefox-78.4.0/js/src/new-regexp -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/build/js/src/new-regexp -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/build/js/src -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/firefox-78.4.0/js/src -I/var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/build/dist/include -I/usr/include/nspr -fPIC -DMOZILLA_CLIENT -include /var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/build/js/src/js-confdefs.h -Wall -Wempty-body -Wignored-qualifiers -Woverloaded-virtual -Wpointer-arith -Wsign-compare -Wtype-limits -Wunreachable-code -Wwrite-strings -Wno-invalid-offsetof -Wduplicated-cond -Wimplicit-fallthrough -Wunused-function -Wunused-variable -Wno-error=maybe-uninitialized -Wno-error=deprecated-declarations -Wno-error=array-bounds -Wno-error=coverage-mismatch -Wno-error=free-nonheap-object -Wno-multistatement-macros -Wno-error=class-memaccess -Wno-error=deprecated-copy -Wformat -Wformat-security -Wformat-overflow=2 -Wno-noexcept-type -fno-sized-deallocation -fno-aligned-new -march=x86-64 -O2 -pipe -std=gnu++14 -fno-rtti -ffunction-sections -fdata-sections -fno-exceptions -fno-math-errno -pthread -pipe -g -fno-omit-frame-pointer -funwind-tables -fno-strict-aliasing -Werror=format -Wno-shadow -Wno-attributes -DV8_INTL_SUPPORT  -MD -MP -MF .deps/special-case.o.pp   /var/tmp/portage/dev-lang/spidermonkey-78.4.0/work/firefox-78.4.0/js/src/new-regexp/special-case.cc

Looks like dev-lang/spidermonkey-78.4.0 ebuild should exclude all -std= flags from CXXFLAGS since it forces c++17 usage.

Reproducible: Always
