Обсуждение: Problem configuring PostgreSQL 8.1.4 on Mac OS X

Greetings,

There is a problem with PostgreSQL 8.1.4 on Mac OS X (PowerPC).

The 'configure --enable-thread-safety' script fails when CFLAGS
contain "-mcpu=7400", "-mcpu=970" or "-maltivec". With these flags,
the GCC compiler enables AltiVec instructions for the PowerPC
processor, and defines:

#define __ALTIVEC__ 1
#define __VEC__ 10206
#define __vector __attribute__((altivec(vector__)))
#define __pixel __attribute__((altivec(pixel__))) unsigned short
#define __bool __attribute__((altivec(bool__))) unsigned
#define vector vector
#define pixel pixel
#define _Bool _Bool
#define bool bool

src/tools/thread/thread_test.c, fired for '--enable-thread-safety',
failes for not having the correct definition for 'bool'.

I would suggest using 'BOOL' for you boolean variables, instead of
'bool'.

Please, fix. :)

Kind regards,
Adam

Uh, thread_safety is only the first test that uses 'bool'.  The entire
backend uses it.  What is:

    #define bool bool

supposed to accomplish?  I suggest you avoid AltiVec until the vendor
fixes the includes.

This has been discussed before, and the conclusion was "don't do that".

Not bloody likely.
