[Looks like I'll soon be suspending my FreeBSD explorations for a time =
again. 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.
