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

问题

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.

回答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.

回答2:

apt-get install build-essential

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

回答3:

1) Install .exe from > https://sourceforge.net/projects/mingw-w64/

1.2) ! use x86_64 architecture

2) Add C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin to PATH in User Variables and in System Variables. For me it works.

! To edit Path variable press Windows key, type 'path', choose 'Edit the system environment variables', click 'Environment Variables', find Path variable in System variables and in User variables then edit.

The proper explanations why go build does not work for hyperledger in Windows environment are given as other answers. For your compilation purposes, just to make it work without installing anything extra, you can try the following

go build --tags nopkcs11

It worked for me. I hope same works for you too.

On window install http://tdm-gcc.tdragon.net/download, after installed it, you need to reset your PC. that all

Instruction to fix the "exec: “gcc”: executable file not found in %PATH%" error with MSYS2:

Download MSYS2.
Put MSYS2 folder into your $PATH.
Start the MSYS2 command line program.
Run this command: pacman -S gcc.

回答7:

gcc should not be necessary, unless you are cross compiling for a non-windows platform, or use cgo. If you still need gcc, however, you should install MinGW, which provides a gcc port for Windows (Cygwin and msys should also work, although I have never actually tested this).

Edit: I see from your error message now, that it is a dependency that requires gcc. If you didn't already know this, gcc is a c/c++ compiler, and in this case it is probably needed to compile c source files included by a dependency or sub-dependency.

回答8:

you need to download MingGW64
put MingGW64 folder into your $PATH
run go build xxx.go (with cgo library)

Hi jaswanth the main problem is that you haven't register your %GO_HOME%\pkg\tool\windows_amd64 to yuour Environment Path. %GO_HOME% is the repository where you install your go at the first time.
