BUG #1250: compilation fails in src/backend/storage/lmgr/s_lock.c
The following bug has been logged online:
Bug reference: 1250
Logged by: Aidan Dixon
Email address: Aidan.Dixon@Blueyonder.co.uk
PostgreSQL version: 8.0 Beta
Operating system: Sun/Solaris9/64bit
Description: compilation fails in src/backend/storage/lmgr/s_lock.c
Details:
Compiler: SUNWspro (Forte Developer 7) cc
The code in s_lock.c uses a ".seg" directive where ".section" seems to be
in vogue, judging from the output of "cc -S" for a simple "hello world" type
program.
Build output:
make[4]: Entering directory
`/share/build/postgresql-8.0.0beta2/src/backend/storage/lmgr'

Hmm. So how can we distinguish your version of Solaris from the ones
that want ".seg"?

The SUNWspro man page for cc(1) contains the following (entries for -xarch=v9
i.e. 64bit sparc apply in my case)
...
Predefinitions:unix
sparc (SPARC)
i386 (x86)
sun
The above are not predefined in -Xc mode.
These predefinitions are valid in all modes:
__sun
__unix
__SUNPRO_C=0x540
__`uname -s`_`uname -r`
__sparc (SPARC)
__sparcv9 (SPARC with -xarch=v9|v9a|v9b)
__i386 (x86)
__BUILTIN_VA_ARG_INCR
__SVR4
The following is predefined in -Xa and -Xt modes only:
__RESTRICT
The compiler also predefines the object-like macro
__PRAGMA_REDEFINE_EXTNAME,
to indicate the pragma will be recognized.
...
Guess the ___SUNPRO_C macro is a start. 'fraid the only other compiler I can
test against is gcc-3.4.1. Any suggestions, I'll give 'em a try.
Regards,
-a.
