Re: [xmlblaster] Compiling cpp client in mac osx

Hi,

Regarding the compilation:

Neither the build.properties CFLAGS or the command line worked. I  
shouldn't worry about this, using a include directive should work.

Regarding the msgUtil.c and gethostbyname_r:

From what I could gather __MacOSX__ should be implicitly defined.  I  
made the following change on msgUtil:

----
#ifndef _WINDOWS	 /* Windows does not support the reentrant ..._r()  
functions */
#	if defined(__sun)
#	  define HAVE_FUNC_GETHOSTBYNAME_R_5 /* SUN */
#	elif defined(__alpha)
#	  define HAVE_FUNC_GETHOSTBYNAME_R_3 /* OSF1 V5.1 1885 alpha */
#	elif defined(__FreeBSD__)
#	  define LOCAL_GETHOSTBYNAME_R /* FreeBSD */
/* this should actually work for other platforms... so long as they  
support pthreads
Jota -> it Does! I used it on MacOSX */
#  elif defined(__MacOSX__)
#    define LOCAL_GETHOSTBYNAME_R /* Mac OSX */
#	elif defined(__hpux) /* with gcc 2.8 - 3.4.3 */
#	else
//!!!Jota - OSX is a BSD-like system, thus defining  
LOCAL_GETHOSTBYNAME_R also works on OSX.
//!!!It should be react to __MacOSX__ but my system didn't  
acknowlegde the define.
#	  define HAVE_FUNC_GETHOSTBYNAME_R_6 /* Linux */
#	endif
#endif
----

It compiled and worked! Thus the code for BSD also works on Mac. -  
results below -

cesar:~/src/xmlBlaster/src/c/util jota$ gcc -g -Wall -o msgUtil  
msgUtil.c helper.c -I.. -DMSG_UTIL_MAIN=1 -D__MacOSX__
cesar:~/src/xmlBlaster/src/c/util jota$ ./msgUtil
Hello 'localhost'


But xmlBlaster still has problems in the ./build process. It seems  
that the __MacOSX__ isn't defined. In order to compile I changed the

#  elif defined(__hpux) /* with gcc 2.8 - 3.4.3 */
#  else
#    define HAVE_FUNC_GETHOSTBYNAME_R_6 /* Linux */
#  endif
#endif

to

#  elif defined(__hpux) /* with gcc 2.8 - 3.4.3 */
#  else
#    define LOCAL_GETHOSTBYNAME_R /* Linux */
#  endif
#endif

Also, the prebind problem still exists. Unfortunately I don't have  
experience with the cppTasks. Can we change options in cppTasks so  
that the prebind doesn't get used?


In short:

- The malloc.h is in the wrong place. XmlBlaster need an include  
directive
- Even though the BSD code works, the __MacOSX__ doesn't seem to be  
defined.
- In binding phase , MacOSX uses prebind (as do the cppTasks). We  
need a workabout on this, maybe turn it off and using the old fashion  
-L/usr/lib -L/sw/lib -lsqlite -lz

Thanks, Ricardo Jota
