Hello,
I've create a docker images with ubuntu 20.10 with GOLLVM, I'm using at the
moment a simple test repository
<https://github.com/bestbug456/gollvmRepository>, I was able to create the
ll file with the following command:
go build -gccgoflags -static-libgo -x -work 1> transcript.txt 2>&1
WORK=$(egrep -m 1 '(WORK=|llvm-goc -c)' transcript.txt | awk '{ print
substr ($0, 6 ) }')
/gollvm/install/bin/llvm-goc -c -O2 -g -m64
-fdebug-prefix-map=$WORK=/tmp/go-build \
-gno-record-gcc-switches -fgo-pkgpath=$PWD \
-fgo-relative-import-path=$PWD -o $WORK/b001/_go_.o \
-I $WORK/b001/_importcfgroot_ -o $LLFILE -S -emit-llvm $MAINFILE
But when I try to convert to binary via clang the file I've some error:
clang helloworld.ll -o helloworldLLVM
warning: overriding the module target triple with x86_64-pc-linux-gnu
[-Woverride-module]

clang: error: linker command failed with exit code 1 (use -v to see

I'm this is the first time I use this buildchain and I don't understand
what I'm doing wrong. Can someone help me?
Those are the commit I've used for build gollvm, if needed
