Hello,

I want to pass the '-Wl,--split-stack-adjust-size=0x8000' to the gold linker as follows:

go build -o libgotest.so -buildmode=c-shared -compiler=gccgo -gccgoflags='-Wl,--split-stack-adjust-size=0x8000' test_mmap.go

But there s "unrecognized option" error. Could you please tell me the correct way of passing these flags?

Thank you!

What you wrote looks about right to me. What is the exact and complete output?

Aha, I got the problem. I should have added -fuse-ld=gold. The following works well.

go build -o libgotest.so -buildmode=c-shared -compiler=gccgo -gccgoflags='-fuse-ld=gold -Wl,--split-stack-adjust-size=0x8000' test_mmap.go

Thank you!
