This suggests that the CC environment variable is set to
".\\msys64\mingw64\bin\gcc.exe" with a leading dot.  That is not an
absolute path.  That is not permitted for the reasons given at
https://golang.org/issue/43783.

[go-nuts] cgo error I don't understand

[Robert Solomon]

I'm setting up a new Windows10 computer.  I installed Go 1.17.2 and mingw64 
for cgo.  When I tried to compile a project that uses cgo, I got this error:

cgo: exec gcc: gcc resolves to executable relative to current directory 
(.\\msys64\mingw64\bin\gcc.exe)

This is a program that compiles fine on my older win10 computer.

I don't think this matters, but I'm compiling a program of mine that uses 
fyne, which uses cgo.
