cmd.go is referencing to undefined identifier 'log.Context' , main.go is referencing to undefined identifier 'vmextension.FindSeqNumConfig'

Start with Makefile and reproduce the reported make command using the stated Go/gollvm environment. Then inspect the undefined references in main/cmds.go and main/main.go, separating those errors from the gccgo linker warning and llvm-goc crash. Done means the project builds successfully with the affected toolchain, or the supported toolchain requirements are documented.

Hi.
I can't build your project.

I have

$ go version
go version go1.15.2 gollvm LLVM 12.0.0git linux/amd64

and

$ go env
GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/oceanfish81/.cache/go-build"
GOENV="/home/oceanfish81/.config/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOINSECURE=""
GOMODCACHE="/home/oceanfish81/go/pkg/mod"
GONOPROXY=""
GONOSUMDB=""
GOOS="linux"
GOPATH="/home/oceanfish81/go"
GOPRIVATE=""
GOPROXY="https://proxy.golang.org,direct"
GOROOT="/home/oceanfish81/gollvm_dist"
GOSUMDB="sum.golang.org"
GOTMPDIR=""
GOTOOLDIR="/home/oceanfish81/gollvm_dist/tools"
GCCGO="/home/oceanfish81/gollvm_dist/bin/llvm-goc"
AR="ar"
CC="/usr/bin/clang"
CXX="/usr/bin/clang++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build329472087=/tmp/go-build -gno-record-gcc-switches -funwind-tables"

So here is what I got:

$ make
rm -rf "bin" "bundle"
if [ -z "$GOPATH" ]; then
echo "GOPATH is not set";
exit 1;
fi
GOOS=linux GOARCH=amd64 govvv build -v

-o bin/run-command-extension ./main
go build: when using gccgo toolchain, please pass linker flags using -gccgoflags, not -ldflags
