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.
