So this completes my notes for the subject and related material.] Reminder of the "long int" issue in = gcc-4.9.1/gcc/config/rs6000/freebsd64.h that gets the wrong type for L" = . . . " notation for FreeBSD: > /* rs6000.h gets this wrong for FreeBSD. We use the GCC defaults = instead. */ > #undef WCHAR_TYPE > #define WCHAR_TYPE (TARGET_64BIT ? "int" : "long int") > #undef WCHAR_TYPE_SIZE > #define WCHAR_TYPE_SIZE 32 I did try changing my = /usr/obj/portswork/usr/ports/devel/powerpc64-gcc/work/gcc-4.9.1/gcc/config= /rs6000/freebsd64.h so that WCHAR_TYPE would always use "int" and = rebuilding powerpc64-gcc. With that I was able to compile lib32, no = longer having a bad type for the L prefix notation on string literals. So I expect that requesting a fix upstream and/or patching such files in = gcc ports that have such a "long int" for powerpc FreeBSD targets is = appropriate. Side note likely specific to my context in some way . . . Unfortunately that lib32 built did not mean that using it worked. A -g = -m32 compile/link of > int main() > { > return 0; > } produces something for which ./a.out segmentation faults in a way that = neither the system nor the port gdb can report on where. For now it looks like I'm not going to have the time to work on figuring = out any of the issues involved. =3D=3D=3D Mark Millard markmi at dsl-only.net
