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.

go build command giving the above gcc error ... how can i solve itjaswanth
Do you have gcc installed?zerkms
no .. is it required ?jaswanth
@jaswanth: Your error message is "gcc": executable file not found. That should be your first clue that "gcc" is required but not found.Flimzy

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.

If you are running Ubuntu do:

apt-get install build-essential

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

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.

I also encountered this message, but in my case, it was missing gcc.exe. I used choco and installed mingw, and then it worked.

details:

  1. download choco
  2. choco install mingw -y
  3. check: gcc -v

You can try - this is not a solution but a temp workaround

cgo_enabled=0 go build 

Once you install gcc - and make sure %PATH has a way to find it (gcc.exe) - this should go away.

Also running this one will ensure the cgo_enabled variable will stay this way as long as terminal is open. That way you don't have to prefix it each time you do a build.

export cgo_enabled=0 go build

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.

If you are using an alpine based image with your Dockerfile

Install build-base which will be met with your requirements.

If you are running Ubuntu do:

sudo apt-get update
sudo apt-get install build-essential.

If the above commands do not work do:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe"

The main component contains applications that are free software, can be freely redistributed and are fully supported by the Ubuntu team. & The universe component is a snapshot of the free, open-source, and Linux world.

Then install package by following command in terminal:

sudo apt-get update
sudo apt-get install build-essential.

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.

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.

same as other, just install tdm-gcc, but you can use its terminal, "MinGW", you can access it from start menu folder tdm-gcc, after start, browse to your project, and run it again

I'm a Windows user and I downloaded tdm-gcc (MinGW-w64 based) from the link below:

https://jmeubank.github.io/tdm-gcc/

After installation, it made a folder named "TDM-GCC-64".

I added "C:\TDM-GCC-64\bin" to my PATH, And it fixed my problem.
