- Subject: [PATCH] gn.pro: don't link statically with libstc++
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- While cross-compiling, qt5webengine is building a host tool but
- want to link the libstdc++ statically. This requires to install
- libstdc++-static package on the host (Fedora package name).
- Otherwise the link fail with:
- [185/185] LINK gn
- FAILED: gn
- /usr/bin/g++ -O3 -fdata-sections -ffunction-sections -Wl,--gc-sections -Wl,-strip-all -Wl,--as-needed -static-libstdc++ -pthread -o gn -Wl,--start-group tools/gn/gn_main.o base.a gn_lib.a -Wl,--end-group -ldl
- /usr/bin/ld : unable to find -lstdc++
- [...]
- Project ERROR: GN build error!
- Add --no-static-libstdc++ argument to gn.pro to link to
- libstdc++.so.6 instead of libstdc++.a.
- --no-static-libstdc++ has been added by [1] but it force
- linking statically by default.
