Building llvm/clang from source involves using CMake. I am building
llvm/clang from source on Windows using CMake 3.5.2. I am not a clang
developer, just a clang user. Similarly I just use CMake rather than
understand or write CMakeLists.txt files.
I reported a problem to clang where building a 32-bit version of clang
succeeds but building a 64-bit version of clang fails with xml link
errors. I have A 32-bit libxml2 binary in my path from gnuwin32, but not
a 64-bit binary of libxml2 in my path.
I was told by clang developers that one of the tools which clang builds
uses xml and libxml2 if it is available, otherwise uses some other
technology for the tool. The suggestion was that the problem I am
encountering is that of CMake; that CMake does not recognize that the
libxml2 which I have is the 32-bit version and instead thinks that it is
the 64-bit version and therefore attempts erroneously to use it in the
64-bit build of clang.
Does anybody know what might be happening here ? I do not create the
CMakeLists.txt files used by llvm/clang so I do not know how the use of
libxml2 can be optionally specified in them.
