Building faust fails with MSYS2 MinGW 64-bit when including LLVM backend (make all or make developer)

[jonayoung2003]

Hi I have been trying to build faust with msys2 because I would like to use the benchmark tools which are not included when you install faust with the installer. I have followed these instructions to try to build faust with msys2 (MinGW 64-bit on Windows 10). This works if I do the default building of Faust (just by calling make alone as per instructions) and I can see in build/bin a faust.exe file is generated. However, if I try to call make all or make developer the build appears to proceed successfully up until linking the faust.exe file where it fails. Apparently I need to call make all or make developer so I can then follow these instructions to install the benchmark tools I need. I always ensure I call git clean -fdx between builds to make sure any build files are removed before building again (as recommended here). Is this a known issue and is there a workaround? My best guess is that this issue is something to do with the fact that make all or make developer differs from make by compiling and installing the LLVM backend. However, I also noticed that I had to deviate slightly from the msys2 instructions. A call to pacman -S mingw-w64-x86_64-make did not allow me to call make so I had to also call pacman -S make in order to do this. Could this be the cause of the problem?

Below is the output of the build step that fails (seems to be something to do with finding multiple definitions for the same thing):
