Hi,

I have tried for hours and days to install LLGOon ubuntu 16.04 without success using the following link:
https://github.com/llvm-mirror/llgo
Each time got different error.

I went through the forum and tried several solutions.

The last phase I got was failing at 94% on the following error:
"
[ 94%] Performing configure step for 'libgo'
-- libgo configure command succeeded. See also /path/to/llvm-build/tools/llgo/libgo-prefix/src/libgo-stamp/libgo-configure-*.log
[ 94%] Performing build step for 'libgo'
CMake Error at /path/to/llvm-build/tools/llgo/libgo-prefix/src/libgo-stamp/libgo-build-Debug.cmake:16 (message):

I'm getting the same, looks like there's something wrong with debug info:

inlinable function call in a function with debug info must have a !dbg location

call void @"sync.init#1"(i8* nest undef)

inlinable function call in a function with debug info must have a !dbg location

call void @"sync.init#2"(i8* nest undef)

LLVM ERROR: Broken function found, compilation aborted!

make[2]: *** [sync.lo] Error 1

I'll try to look into it soon.

Is there any slight chance someone is willing to upload Virtaul Machine with working LLGO to my dropbox?
Thank you so much!!!!

I'm in the process of packaging llgo as a "snap" (http://snapcraft.io/). I'll mail the list when it's ready.

Cheers,

Andrew

Wonderful news about packaging llgo as a "snap" Andrew, I'll look forward to trying it!

The fix is here: https://reviews.llvm.org/D22905. You only need the change to debug.go, the other is just to help in debugging codegen.

This helped me to build libgo without a problem. However it appears llgoi also needs some love, as below. Any help appreciated!

I'm not able to reproduce this at the moment. I've just done a fresh build of llgoi without any problems. Sorry.
