cgo static build failed of "undefined reference to `__longjmp_chk'"

WeiZhang555 commented 3 years ago

Describe the bug

wasmer-go is vendored in my private golang project, for removing unnecessary dependencies, I was trying to build my project with wasmer in cgo static build mode but failed, can you give me some guide how to make it work?

Steps to reproduce

Download github.com/wasmerio/wasmer, cd wasmer dir, git checkout -b v2.0.0 2.0.0 switch to 2.0.0 release.

run make to compile, got result as

$ ls -l target/release/
total 105164

In my own project, "wasmer-go" master code is vendored, commit id: 72b0251581c7

Compile my own code in my Makefile with command

CGO_CFLAGS="-I/home/zhangwei/program/gocode/src/github.com/wasmerio/wasmer/lib/c-api/" \
CGO_LDFLAGS="-Wl,-rpath,/home/zhangwei/program/gocode/src/github.com/wasmerio/wasmer/target/release/ -L/home/zhangwei/program/gocode/src/github.com/wasmerio/wasmer/target/release/ -pthread -lwasmer_c_api -lm -ldl -static" \
CC=/usr/bin/musl-gcc \
go build -mod vendor -tags custom_wasmer_runtime -ldflags "-X xxx.GitCommit="xxx" -X xxx.Version=xxx"  -o <bin> .

Expected behavior

The compilation should succeed and binary should be compiled as static.

Actual behavior

Got compilation error:

# github.com/wasmerio/wasmer-go/wasmer

Can you give me some tips how to make it work? Thanks in advance!

Hello,

Thank you for the detailed bug report. Can you please provide me your platform (OS) and architecture (CPU)? I see you're using musl. Did you compile Wasmer with LIBC=musl?

Do you consider providing users with a universal container environment so that everyone can reproduce the problem? @Hywan
