I'm building a .so on linux (64bit ubuntu) that is used in a closed-source
application. Build steps:
go build -buildmode=c-archive gfeeder.go
cc -c -fPIC -pthread cfeeder.c
cc -c -fPIC -pthread feeder.c
ld -shared -o feeder.so feeder.o cfeeder.o gfeeder.a
$ cat gfeeder.go
package main
import (
"C"
)
//export AddInt
func AddInt(x int) int {
return x + 4
}
func main() {}
$ cat feeder.c
typedef long long GoInt64;
typedef GoInt64 GoInt;
extern GoInt AddInt(GoInt p0);
long feed(long y) {
long z;
z = AddInt(y);
return z;
}
When I run the proprietary application with my .so it segfaults at the very
end of the process. If I put a sleep() call in feeder.c after the AddInt
call, the process exits gracefully.
My intuition tells me it's some kind of pthread issue (or something else in
the golang runtime). Is there some kind of clean up function I can call for
the golang runtime? Or maybe some kind of pthread wait/join I can use? The
example code I found for pthread join requires thread ids. I don't know how
to get those from the golang runtime.
