"...build constraints exclude all Go files in..."

[catrevil]

I'm not sure how to get around this.

I'm trying to cross-compile this for windows 64 bit since the "...gcc.exe: filename too long..." issue on windows is due to the limitations of the OS's FILENAME length.

Upon search of the error, there is a claim that you cannot cross-compile something that uses cgo?

I just want to use this for windows 64 bit...
What do you advise?

I have all dependent packages in what I assume are there appropriate directory structures.

The error is as follows:
GOOS=windows GOARCH=amd64 go build

../../barnex/fftw/fftw.go:7:2: build constraints exclude all Go files in /home/catrevil/go/src/github.com/barnex/fftw/internal/double

../../barnex/fftw/fftw.go:8:2: build constraints exclude all Go files in /home/catrevil/go/src/github.com/barnex/fftw/internal/float

It is actually possible to compile this for Windows 10 on a Linux machine! I am not sure how to make it version check as of right now, but one needs only to set anything related to memalign to 0 instead of 1 within the config.h file, while additionally setting HAVE_MALLOC_H (iirc) to 0, while ensuring that OUR_MALLOC was set to 1. I also used xgo for this, but I think it can be done in a simpler manner. Making the changes notes would cause an inability to compile for other OS if my understanding is correct.
