very weird, looks like your toolchain is broken..

Are you sure that Target: mingw32 is an amd64 target? Please double-check the arch.

martin-guthrie-docker commented 6 years ago

Note the GCC output above, it says Target mingw32. I googled around and saw that one could set environment variable MSYSTEM to mingw64, which I did, no change in result.

I am able to build other Go programs, specifically some easy tutorial go programs.

okay I "think" I understand what the issue is.... The install of MinGW I have is for 32bit systems, but my machine is a 64bit system. I was lead to cygwin for MinGW 64bit version, and when I build in a cygwin shell, I get,

$ go get github.com/golang-ui/nuklear/cmd/nk-example /# github.com/go-gl/glfw/v3.2/glfw In file included from C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw\c_glfw_windows.go:6:0: C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw/glfw/src/win32_monitor.c: In function 'createMonitor': C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw/glfw/src/win32_monitor.c:68:5: warning: implicit declaration of function 'wcscpy' [-Wimplicit-function-declaration] wcscpy(monitor->win32.adapterName, adapter->DeviceName); ^~ C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw/glfw/src/win32_monitor.c: In function '_glfwPlatformIsSameMonitor': C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw/glfw/src/win32_monitor.c:228:9: warning: implicit declaration of function 'wcslen' [-Wimplicit-function-declaration] if (wcslen(first->win32.displayName)) ^~ C:\Users\Martin\go\src\github.com\go-gl\glfw\v3.2\glfw/glfw/src/win32_monitor.c:229:16: warning: implicit declaration of function 'wcscmp' [-Wimplicit-function-declaration] return wcscmp(first->win32.displayName, second->win32.displayName) == 0; ^~ /# github.com/golang-ui/nuklear/cmd/nk-example C:\Go\pkg\tool\windows_amd64\link.exe: running gcc failed: exit status 1 /usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lmingwex /usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lmingw32 collect2: error: ld returned 1 exit status

So I think its an issue with using the "MinGW installer" link that is in the instructions, which is a 32bit gcc, versus my machine being 64bit. But I am just hypothesizing...

I was unable to find the missing files, and I suspect cygwin doesn't have these libs, so this may be a deeper make issue, which is beyond my pay grade...

I am willing to get to the bottom of this but I would need direction...

xlab commented 6 years ago

Based on all the experience I have, it seems that you've gone too far off the radar, the later errors are not common and it seems that your MinGW is totally broken.

It's important that Go's arch and GCC's arch match, you can get 64/64 or 32/32 on the same 64-bit machine, but they must match.

@martin-guthrie-docker Please remove any trace of MinGW/MSYS from your system and install by the steps from README:

martin-guthrie-docker commented 6 years ago

Thank you for the help.

I removed my previous MinGW, and installed new (64bit) one from this link,

https://sourceforge.net/projects/mingw-w64/?source=typ_redirect

I do start the batch file msys to get a console.

It seems this is a known issue,

https://github.com/go-gl/glfw/issues/202 In that issue it says to select 686 target, but that is for 32bit...

I tried using msys2 from https://www.msys2.org but got the same result.
