Comment (by barracuda156):

 Replying to [comment:4 kencu]:
 > perhaps try building a simple "hello.c" and "hello.cxx" program with
 gcc7 as ppc64, and if they can be compiled, run them both to see if they
 work at all.

 code on darwin...

 Hmm, doesn't look good:


 {{{
 36-225:Dev svacchanda$ gcc-mp-7 -arch ppc HelloWorld.c -o HelloWorld
 HelloWorld.c:2:1: warning: return type defaults to 'int' [-Wimplicit-int]
  main() {
  ^~~~
 36-225:Dev svacchanda$ /Users/svacchanda/Dev/HelloWorld
 hello, world
 36-225:Dev svacchanda$ gcc-mp-7 -arch ppc64 HelloWorld.c -o HelloWorld
 HelloWorld.c:2:1: warning: return type defaults to 'int' [-Wimplicit-int]
  main() {
  ^~~~
 36-225:Dev svacchanda$ /Users/svacchanda/Dev/HelloWorld
 Segmentation fault
 36-225:Dev svacchanda$ file /Users/svacchanda/Dev/HelloWorld
 /Users/svacchanda/Dev/HelloWorld: Mach-O 64-bit executable ppc64
 36-225:Dev svacchanda$ gcc -arch ppc64 HelloWorld.c -o HelloWorld
 36-225:Dev svacchanda$ /Users/svacchanda/Dev/HelloWorld
 hello, world
 36-225:Dev svacchanda$ file /Users/svacchanda/Dev/HelloWorld
 /Users/svacchanda/Dev/HelloWorld: Mach-O 64-bit executable ppc64
 36-225:Dev svacchanda$

 }}}

 64-bit file made by Apple gcc works, while the one made by Macports gcc7
 fails.

 P. S. Basic program used:


 {{{
 #include <stdio.h>
 main() {
   printf("hello, world\n");
 }
 }}}
