pkg-config errors on windows compiling v8

Question

I am trying to build ry/v8worker2 on windows. Everything goes fine until the point where I run go test which then complains about the pkg-config setup.

This is the pkg-config file which is generated:

Name: v8
Description: v8
Version: xxx
Cflags: -IC:\Users\andyrea\go\src\github.com\reaandrew\v8worker2\v8\include
Libs: out/v8build/obj/v8_monolith.lib

And this is the output when go test is executed:

go build github.com/reaandrew/v8worker2: invalid flag in pkg-config --libs: out/v8build/obj/v8_monolith.lib
FAIL    github.com/reaandrew/v8worker2 [build failed]

As I say, the entire compilation went fine and files were created but at the end something is not correct. The only modifications to the build.py I have made to try and make this work on windows as here:

There is very little documented (that I can find) about how to compile this project on windows.

UPDATE: If I change the pkg-config to:

Name: v8
Description: v8
Version: xxx
Cflags: -Iv8/include
Libs: -Lout/v8build/obj/v8_monolith.lib

Then the output of go test is now:

Answer 1

For security reasons, the Go compiler has a whitelist of arguments that can appear in pkg-config files, and refuses to use arguments that don't appear on the list. One whitelist entry allows pointing the linker to static libraries directly: it covers files with the extension .a, but not .lib.

You can try putting [a-zA-Z0-9_/].*\.lib in the CGO_LDFLAGS_ALLOW environment variable to make it pass the check… but I suspect that this would probably not work anyway: .lib files are produced by MSVC, and they are in a different format from Unix ar (which is what .a files are, and probably what the Go compiler expects). The real fix would be get V8 to compile with GCC instead of MSVC and produce a proper .a file, but V8 doesn't officially support it on Windows, and getting it to work would apparently require a far more invasive patch.
