Bug#954438: libgccjit0: GCCJIT leads to linking error

[Gong-Yi Liao <gliao.tw@pm.me>]

Package: libgccjit0
Version: 10-20200312-2
Severity: important

Dear Maintainer,

libgccjit0 leads to linking error, I have the following C source code: 

#include <libgccjit.h>
#include <math.h>
#include <stdio.h>

int main(int argc, char **argv) {
	gcc_jit_context *ctxt;
	ctxt = gcc_jit_context_acquire();
	gcc_jit_rvalue *args[2]; 
	printf("%5.8lf\n", sin(30)); 
	return 0;
}


and I compiled it using the following command line:

gcc-10 test.c -o test -lgccjit

or 

gcc-10 test.c -lgccjit -o test 

leads to the same error message:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/9/libgccjit.so: undefined reference to `lang_register_spec_functions()'
collect2: error: ld returned 1 exit status

However, exactly the same gcc and gccjit version on Fedora Rawhide work as intened. 

It seems a gccjit issue rather than a ld issue. 

Thanks, 
Gong-Yi.
