| 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. |
