Bug ID: 90665
   Summary: undefined C type 'int' with gcc 9.1.0 on solaric
   Product: gcc
   Version: 9.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: go
  Assignee: ian at airs dot com
  Reporter: thorsten.knieling at googlemail dot com
CC: cmang at google dot com
  Target Milestone: ---

I built gcc 9.1.0 on Solaris 11 (SPARC) from sources (GNU). The build went well
and CGO free Go code can be compiled and works.

With CGO code the gccgo build does not compile. go code referencing any C
standard type like C.int returns an error:

sh> go build ./...
./main.go:18:2: call of non-function C.f
./main.go:18:6: invalid conversion to C.int: undefined C type 'int'

Here is the simple example code which does not build.

package main

/*
#include 

void f(int i) {
  fprintf(stdout,"INT: %d\n",i);
}
*/
import "C"

import (
"fmt"
)

func main() {
// Simple C function call.
C.f(C.int(1))
fmt.Println("ABC")
}

--- Comment #2 from Thorsten A. Knieling  ---
May be I use the wrong configure options.
I used a gcc compiler rather then an Solaris compiler to build gcc 9.1.0.

My configure looks like this
../configure --prefix=/gcc-solaris-9.1.0
--enable-languages=c,c++,go,objc,lto

Could you give an hint?
