[LLVMdev] LLVMgold.so in windows LLVM builds
I tried building it on windows with some CMake changes. But unfortunatelym my clang crashes when it tries to access the LLVMgold (not able to open it). I have CCed Rafeal and Nakamura who might know why gold plugin in not supported on Windows platforms. --Sumanth G> Hi, > > On 14 June 2014 00:26, <sgundapa at codeaurora.org> wrote: >> I am trying to build LLVMgold.so on windows. >> I came across this piece of code which includes âgoldâ source >> directory in >> tools/CMakeLists.txt > > It seems to date from the original gold import in 2011, so it's > probably just from being careful. > > Disabling the check is worth a try, though I think even the binutils > Windows linkers use something other than Linux's ELF.

I have no idea if the plugin infrastructure works on windows or not, but it could be made to work since all it needs is to find a single symbol in the plugin.
