[Pkg-gauche-devel] Bug#749823: gauche-gl: Conflicting declarations of function Scm_Init_gl_syms

[Michael Tautschnig]

Package: gauche-gl
Version: 0.5.1-1
Usertags: goto-cc

During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and pbuilder) the build failed with the following error. Please note that we
use our research compiler tool-chain (using tools from the cbmc package), which
permits extended reporting on type inconsistencies at link time.

I'm not quite sure which end is wrong here, but I'd interpret

http://sources.debian.net/src/gauche-gl/0.5.1-1/src/gen-syms.scm?hl=47#L47

as generating the code for Scm_Init_gl_syms, hence the declaration here

http://sources.debian.net/src/gauche-gl/0.5.1-1/src/gauche-gl.c?hl=448#L448

would be wrong and the call passing an argument is wrong as well.

Best,
Michael
