| Description | I tried compiling the MPS on my laptop, which is currently running Mac OS X 10.3.4. I got the following error: > xcppgc: xcppgc/hi/testlib.o > In file included from /usr/include/math.h:26, > from testlib.c:13: > /usr/include/architecture/ppc/math.h:505: error: conflicting types for > `cabs' > osxc.h:24: error: previous declaration of `cabs' > make[2]: *** [xcppgc/hi/testlib.o] Error 1 > make[1]: *** [target] Error 2 > make: *** [mpmss] Error 2 See also job000602 for a very similar report. |
| Analysis | osxc.h says: > /* cabs doesn't have a proper prototype; taken from glibc 2.0.6 > manual. */ > /* Define a structure tag to avoid warnings. */ > struct mps_complex { double real, imag; }; > extern double cabs(struct mps_complex z); Looks like this is no longer true. We need to figure out when this changed in Mac OS X and make this conditional. With this hacked out the MPS compiles just fine and mpmss runs and fails to find defects. 2005-01-28 DRJ: It may be possible to use <AvailabilityMacros.h> to determine what system we are compiling on. EG MAC_OS_X_VERSION_10_3 is only defined on 10.3 and above. |

| 142435 | closed | 2005-02-02 18:01:36 | Richard Kistruck | Remove obsolete wrokarounds for historical problems in ancient Mac OS X headers: these workarounds are no longer needed. Also, note this removal in new file .../mps/master/manual/build-notes/. Also, add reference to this file in index of manuals. |
