[cfe-users] Adding linker flag `-save-temps` resolves the clang-8 error: "unable to make temporary file"

Hi clang users, I am using Windows10 + Cygwin + Eclipse + LLVM toolchain to build a C/C++ project. The files compile fine, but linking with `clang++` fails with multiple `error: unable to make temporary file: No such file or directory`. clang++ -o test "source1.bc" "source2.bc" "source3.bc"

Looks like it writes the files to the current directory - do you have permission to access the current directory? On Wed, Aug 12, 2020 at 6:28 AM Danijel DOMAZET via cfe-users wrote: > > Hi clang users, > I am using Windows10 + Cygwin + Eclipse + LLVM toolchain to build a C/C++

Re: [cfe-users] inconsistent compilation error inside constexpr if

bolt, using LLVM evrsions back to 5.0, Clang does reject the "return ClientMain();" call you aren't seeing an error on. So I'm not sure what compiler/version/situation you're running, but at least at first blush it doesn't look like clang. On Fri, Aug 21, 2020 at 1:29
