Build failed with "undefined reference to `net::CachedNetworkParameters::..."

I tried to build example/server.go with the following options:

CGO_CFLAGS="-I$GOPATH/src/github.com/devsisters/goquic/libquic/boringssl/include" CGO_LDFLAGS="-L$GOPATH/src/github.com/devsisters/goquic/lib/linux_amd64" go build $GOPATH/src/github.com/devsisters/goquic/example/server.go

I'm on linux + go1.6. Previously I have build the static libs with ./build_libs.sh, without problem.

Hello,

Try to do the following: go get -u /github.com/devsisters/goquic cd $GOPATH/src/github.com/devsisters/goquic ./build_libs.sh Now compile with CGO_LDFLAGS="-L$GOPATH/src/github.com/devsisters/goquic/lib/linux_amd64" go build $GOPATH/src/github.com/devsisters/goquic/example/server.go

On my machine Debian Jessie with golang1.6, I got the following error when running my QUIC server: "panic: runtime error: cgo argument has Go pointer to Go pointer" But it seems that this error is due to the Golang bug: https://github.com/golang/go/issues/14210

@Eimji I tried your sequence, but it yields the same errors. Maybe I need to change the build environment? To be exact, I am inside a Ubuntu 14.04 Docker container.

Now I tried to build on OSX, but get basically the same errors (slightly different error message). ./build_libs.sh executed successfully.

Turned out the issue was that I built from a shared folder inside my VM (shared with host). I started from scratch on a folder inside the VM and now it works.

I'm glad to hear it :+1:
