Hi all,

By following `gollvm` document I started to build it. But I got this error in the middle of the build process.

/home/kavindu/GIT/llvm-project/llvm/tools/gollvm/passes/GC.cpp:20:10: fatal error: llvm/CodeGen/GCStrategy.h: No such file or directory

20 | #include "llvm/CodeGen/GCStrategy.h"

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~

compilation terminated.

Could you please help me to solve this issue.

I have used the llvm-project's main branch to build this. Do we need to strict to a special commit in llvm-project to build gollvm?

I am building this on ubuntu 20.04

Thank you,

Kavindu

This change has been submitted; if you update your gollvmn repo you should be able to build cleanly now.

Thanks, Than

Thank you. Do not I need to check out for a special commit? Can I build the gollvm by checking out the latest commits in all dependant repositories(llvm-project, libbacktrace, libgo etc)?

Thank you,

Kavindu

Hi,

cmake -DCMAKE_INSTALL_PREFIX=/my/install/dir -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_LINKER=gold -G Ninja ../llvm-project/llvm

I have tried to run the above command with updated third-party repositories(latest llvm-project) and got the below error. Any idea on this?

error: ‘class llvm::opt::OptTable’ has no member named ‘PrintHelp’; did you mean ‘printHelp’?

104 | opts_->PrintHelp(errs(), progname, "Gollvm (LLVM-based Go compiler)",

| ^~~~~~~~~

| printHelp

ninja: build stopped: subcommand failed.
