When I try to compile dev-libs/libpcre-6.3 with these CFLAGS: CFLAGS="-O2 -mtune=athlon-xp -pipe -fomit-frame-pointer " CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden -fvisibility=hidden" The emerging process fails. If I remove this "-fvisibility=hidden" everything goes OK. Reproducible: Always Steps to Reproduce: 1. Add -fvisibility=hidden to your CXXFLAGS 2. emerge dev-libs/libpcre-6.3 3. Actual Results: This is the begining of the error output: /bin/sh ./libtool --mode=link i686-pc-linux-gnu-g++ -I. -I. -o pcre_scanner_unittest pcre_scanner_unittest.o \ libpcrecpp.la libpcreposix.la i686-pc-linux-gnu-g++ -I. -I. -o .libs/pcre_scanner_unittest pcre_scanner_unittest.o ./.libs/libpcrecpp.so -L/var/tmp/portage/libpcre-6.3/work/pcre-6.3 -L/var/tmp/portage/libpcre-6.3/work/pcre-6.3/.libs /usr/lib/gcc/i686-pc-linux-gnu/3.4.4/libstdc++.so -L/usr/i686-pc-linux-gnu/bin -L/usr/i686-pc-linux-gnu/lib ./.libs/libpcreposix.so /var/tmp/portage/libpcre-6.3/work/pcre-6.3/.libs/libpcre.so -Wl,--rpath -Wl,/usr/lib/gcc/i686-pc-linux-gnu/3.4.4 i686-pc-linux-gnu-g++ -I. -I. -o .libs/pcrecpp_unittest pcrecpp_unittest.o ./.libs/libpcrecpp.so -L/var/tmp/portage/libpcre-6.3/work/pcre-6.3 -L/var/tmp/portage/libpcre-6.3/work/pcre-6.3/.libs /usr/lib/gcc/i686-pc-linux-gnu/3.4.4/libstdc++.so -L/usr/i686-pc-linux-gnu/bin -L/usr/i686-pc-linux-gnu/lib ./.libs/libpcreposix.so /var/tmp/portage/libpcre-6.3/work/pcre-6.3/.libs/libpcre.so -Wl,--rpath -Wl,/usr/lib/gcc/i686-pc-linux-gnu/3.4.4 pcre_scanner_unittest.o: In function `main': pcre_scanner_unittest.cc:(.text+0x91): undefined reference to `pcrecpp::Scanner::Scanner(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' pcre_scanner_unittest.cc:(.text+0xc6): undefined reference to `pcrecpp::Scanner::Skip(char const*)' pcre_scanner_unittest.cc:(.text+0xcc): undefined reference to `pcrecpp::Arg::parse_int(char const*, int, void*)' I'll attach the whole emerge output later.
