Building and testing

Note Go modules are not yet supported.

unset GO11MODULE
go test

If you get a build error from linker like

/usr/lib/go-1.13/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
gcc: error: /home/oleg/go/src/github.com/olegabu/go-secp256k1-zkp/secp256k1-zkp/.libs/libsecp256k1.a: No such file or directory

please build go-secp256k1-zkp library

# clone if needed
mkdir -p $GOPATH/github.com/olegabu
cd $GOPATH/github.com/olegabu
git clone https://github.com/olegabu/go-secp256k1-zkp

# build
cd $GOPATH/github.com/olegabu/go-secp256k1-zkp
CFLAGS="-fPIC" make

this will build dependant C libraries secp256k1-zkp into $GOPATH/github.com/olegabu/go-secp256k1-zkp/secp256k1-zkp/.libs.

TODO

Note CFLAGS="-fPIC" flag is needed to build secp256k1-zkp library for this project while not required for other uses of go-mimblewimble library. This need to be investigated.
