(__ppc64__ vs __PPC64__ porting macros)
(No difference)

Revision as of 11:08, 13 September 2023

Some projects have been ported to Apple ppc64. In that case, they may test macros like this:

  1. if defined(__ppc64__)
  2. endif

GCC does not define __ppc64__. It defines __PPC64__. To make the above code build on Debian ppc64le or Debian ppc64, the summary is: change the above code to:

  1. if defined(__ppc64__) || defined(__PPC64__)
  2. endif
