From 7ae73da23ad998bd1e63ad213cf7a02e61191951 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Sat, 23 May 2020 19:01:19 +0200 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.
