Bug 159264 – [GTK] Debug build broken with Clang

• Component: WebKitGTK
• Status: RESOLVED DUPLICATE

[Carlos Alberto Lopez Perez]

Trying to do a debug build of WebKitGTK+ (on r202623) with Clang and I get this build error:


[5825/6148] Linking CXX shared library lib/libwebkit2gtk-4.0.so.37.14.1
FAILED: : && /usr/bin/clang++  -fPIC -Wno-error  -std=c++1y -fcolor-diagnostics -gsplit-dwarf -Qunused-arguments -g  -Wl,--no-undefined  -L/home/clopez/webkit/webkit/WebKitBuild/DependenciesGTK/Root/lib  -fuse-ld=gold -Wl,--disable-new-dtags -Wl,--gdb-index -Wl,--gdb-index -shared -Wl,-soname,libwebkit2gtk-4.0.so.37 -o lib/libwebkit2gtk-4.0.so.37.14.1 @CMakeFiles/WebKit2.rsp  && :

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.


However, the same build with GCC (gcc-4.9) works.

Preliminary approach

This simple change seems to solve the issue, but I guess we should figure out why we need a destructor now and if that's the case, implement it properly instead of just an empty one.

[Javier Fernandez]

The bug is only reproducible using clang versions above 3.5 .

I'm not totally sure, but perhaps bug #154885 is related to this one.
