exec: "gcc": executable file not found in %PATH% when trying go build

Question

I am using Windows 10. When I tried to build Chaincode it reported this error

# github.com/hyperledger/fabric/vendor/github.com/miekg/pkcs11 
exec: "gcc": executable file not found in %PATH%

My chaincode imports:

import (
    "fmt"
    "strconv"

    "github.com/hyperledger/fabric/core/chaincode/shim"
    pb "github.com/hyperledger/fabric/protos/peer"
)

It's running fine in Docker.

Answer 1

gcc (the GNU Compiler Collection) provides a C compiler. On Windows, install TDM-GCC. The github.com/miekg/pkcs11 package uses cgo. Cgo enables the creation of Go packages that call C code.

Answer 2

If you are running Ubuntu do:

apt-get install build-essential

This solved the problem. It installs the gcc/g++ compilers and libraries.
