Thanks for your reply and sorry for my misunderstanding! I've tried but the problem still exists. My directory layout is: ``` /data00/home/purewhite/gollvm (the `workarea`) /data00/home/purewhite/gollvm/build-debug /data00/home/purewhite/gollvm/llvm-project /data00/home/purewhite/gollvm/llvm-project/llvm/tools/... ``` Which is totally consistent with the README of gollvm.
The error logs are still something like: ``` ... /data00/home/purewhite/gollvm/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:143: no such file or directory: common.go format.go reader.go stat_actime1.go stat_actime2.go stat_unix.go strconv.go writer.go /data00/home/purewhite/gollvm/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:143: no such file or directory: reader.go register.go struct.go writer.go /data00/home/purewhite/gollvm/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:143: no such file or directory: bufio.go scan.go /data00/home/purewhite/gollvm/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:143: no such file or directory: buffer.go bytes.go reader.go ... ``` I think there may be some problems with the `match.sh` script, I will dive into it later. 在2021年11月23日星期二 UTC+8 上午12:54:06<th...@google.com> 写道： > Hi, > > Sorry for the misunderstanding-- > > When I said "from build area root" I am talking about the directory where > you are running "ninja", not the directory that contains the source code > for gollvm.
