Hi, Currently, I can build lld/llvm on Fedora 17 but fail to build it on iMac. The commands I use as follows. Anyone can help me? Or is there the lld mail list I can post the question? Linux/Fedora can be built by the following command cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_FLAGS=-std=c++11 -DCMAKE_BUILD_TYPE=Debug -G "Unix Makefiles" ../src/ make iMac cannot be built by the following command (fail on Xcode compile) cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_FLAGS=-std=c++0x -DCMAKE_B...

I recently had a problem creating LLVMHello. I used this CMake file #!/bin/sh # clangcmake.sh cmake -G "Eclipse CDT4 - Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang ../llvm then I ran make LLVMHello and the build failed on an error about LLVMHello.export The problem turned out to be that the parent directory path had a space in one of the folder names. I removed the space and now LLVMHello builds properly. Hope you fin...

1) Build clang with GCC-4.9.2, when compling other application s with clang/clang++, the default linker is ld, can I replace it with other linker tool， if we can, how to do it? I.E. can we use collect2 instead? 2) how to specify the path, if we do not use the default vertion GCC? Best Regards!

...w32 and that's it (with mingw32-gcc-c++ installed on Fedora 23, also works fine on Ubuntu, Cygwin, etc). I'm trying to recreate this with cmake so we don't get stuck on 3.8 indefinitely.
