[gollvm] Cannot build project : no type named 'CompositeType' in namespace 'llvm'

[gits...@gmail.com]

Hi,

I am currently trying to build the gollvm compiler.

I have followed the instructions provided on the Google source page, up until the "ninja gollvm" instruction, the only difference being that my workarea folder is named build-gollvm. At this point, I get the following error :

[1/1243] Building CXX object tools/gol...pGoFrontEnd.dir/go-llvm-builtins.cpp.o

ninja: build stopped: subcommand failed.

It seems that the CompositeType exists in the mlir/include/mlir/Dialect/SPIRV/SPIRVTypes.h file, but I don't know if it is the same that the one needed here. Having never worked with ninja nor cmake before, I don't know what needs to be changed to include those files - if it is indeed the one we need.

If you need any informations about my environment, feel free to ask me.

Hi,

I'll take a look to see if I can reproduce the problem.

Gollvm is "out of tree", meaning that when LLVM headers and data structures change things can get out of sync, but I'll need to confirm.

Thanks, Than

Hello again,

The gollvm sources were indeed out of date with LLVM tip. I sent

https://go-review.googlesource.com/c/gollvm/+/226637

to resolve the problem. I'll let you know when this is checked in.

Thanks, Than

CL submitted. If you can please update your client and try your build again, it should go through.

Thanks, Than
