The GCC compiler's file may be the problem, please use MinGW-w64. Please check your GCC configuration.

doesn't help, same error(

[tr0mb1r]

Solved, should change gcc compiler in the %PATH%

[henson]

@tr0mb1r 我遇到跟你一样的问题，怎么修改环境变量？没看明白，盼详解，谢谢

[tr0mb1r]

@henson just add your GCC compiler to the %PATH%
My problem was solved with next trick:
set PATH=C:\TDM-GCC-64\bin;%PATH%

[henson]

@tr0mb1r 我已经设置了 TDM-GCC-64\bin 在环境变量里，还是报错

[tr0mb1r]

@henson try to install MinGW-w64 and add it to %PATH%

mingw 32, dowload zlib will be solved:

feel despair.

I tried to do:

brew install gcc
brew install mingw-w64
brew install zlib

// Even I add zlib.h to robotgo/base
// Or install and make zlib

// build to windows amd64, again and again

GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ go build -x ./

// Any way, it told me when build to win amd64:

base/zlib_util_c.h:2:10: fatal error: zlib.h: No such file or directory
#include <zlib.h>
^~~~~~~~
compilation terminated.

// but build to darwin success

I solved the issue by google.
Unzip the package of zlib-x64 to the TDM-GCC dir.

对方啥阵型啊？

All code tests and C dependencies use MinGw-w64, TDM-GCC has not been tested. Cross platform compilation reference #228, #143, #240.

All code tests and C dependencies use MinGw-64, TDM-GCC has not been tested.
But you can compile lpng and lzib yourself, and you can download https://sourceforge.net/projects/mingw-w64/files/ x86_64-posix.

This solution works for me, I record what I've done in this article.
