I've oversimplified things a bit -- what cmake does is write out tools/gollvm/libgo/zgoarch.go.tmp, and then add a build rule for zgoarch.go that copies the *.tmp file to the *.go file if they are different. Do you have tools/gollvm/libgo/zgoarch.go.tmp in your build area? What sort of content is in that file? What happens when you do $ ninja -v -d explain tools/gollvm/libgo/zgoarch.go You should see something like ninja explain: output tools/gollvm/libgo/zgoarch.go doesn't exist [1/1] cd /x/llvm-project/build-relwithdbg/tools/gollvm/libgo && /usr/bin/cmake -E copy_if_different /x/llvm-project/build-relwithdbg/tools/gollvm/libgo/zgoarch.go.tmp /x/llvm-project/build-relwithdbg/tools/gollvm/libgo/zgoarch.go Thanks, Than On Wed, Oct 19, 2022 at 5:42 PM Alex Markin <alexan...@gmail.com> wrote: > There is no zgoarch.go file in the build area.
