• Status: RESOLVED
• Resolution: DUPLICATE
• Component: bmalloc

[Adrian Perez]

Configuring with:

  CC=clang CXX=clang++ CXXFLAGS='-stdlib=libc++' LDFLAGS='-stdlib=libc++ -fuse-ld=lld' \
  cmake -GNinja -DPORT=GTK <…>

results in the following build error:

  Source/bmalloc/bmalloc/AvailableMemory.cpp:120:31: error: implicit instantiation of undefined template 'std::__1::array<char, 256>'
          std::array<char, 256> statmBuffer;

This applied only to the stable webkit-2.24 branch, “trunk”
builds just fine.
