AIX 5.1L , ibm VAC 6.0 compiler
xlc_r -ma -O3 -qstrict -qoptimize=3 -qmaxmem=8192
DB2 7.1
11-27 CVS 

packaged "configure" deleted, rebuilt using buildconf
Configured as:
./configure --with-apxs=/usr/sbin/apxs \
        --enable-track-vars --enable-versioning \
        --with-ibm-db2=/home/db2inst1/sqllib --sysconfdir=/etc \
        --enable-force-cgi-redirect --enable-c9x-inline\
Configure works fine (no warnings or errors), make fails with:
# make

Same compile error on PHP 4.2.3 and 11-27 Stable
Problem is similar to bug #13695, which was closed as "no feedback"

removing "-ma" from CCFLAGS gets rid of the incorrect pragma errors.
No effect on the other problems.
Reset problem type to "Compile Failure" (original intent)
 [2002-12-02 18:57 UTC]
Reclassified as ODBC related problem since that's where the bug is..

 [2002-12-02 23:28 UTC]
Well the CCFLAG isn't set inside of the ODBC config.m4.

Does this happen with only the --with-ibm-db2 option choosen?  Aka whats the minimal amount of configure options that causes this to not happen.

I don't see anything glaringly wrong... the only thing that comes to mind is the ODBCVER issue which hasn't been a problem in the past.

This happens only with "--with-ibm-db2" option in the configure.
When I remove this option and the compile completes, although theres quite a few 'function argument assignment between types "const unsigned char*" and "char*" is not allowed"'
type errors, they don't prevent the make
 [2002-12-05 19:53 UTC]
Okay so when you do a ./configure --with-ibm-db2=/path you get this error?
 [2003-01-02 09:37 UTC] purerory at hotmail dot com
(To answer the question previously posed, yes, I got the error with JUST the ibm-db2 option on the configure line)
Got some help from an IBM compiler expert. Found two environment problems:
1) space between -L and the parameter in LDFLAGS
2) no ANSI setting on the command line
The following environment settings allow the compile to complete successfully:
export CC="xlc_r -qlanglvl=extended -qansialias -O3 -qstrict -qoptimize=3 -qmaxmem=8192 "
export CXX="xlC_r -O3 -qstrict -qoptimize=3 -qmaxmem=8192"
export CFLAGS="-DEAPI -I/usr/local/include -v "
export LDFLAGS="-L/usr/local/lib "
./configure --with-apxs=/opt/freeware/apache/bin/apxs \
        --enable-track-vars --enable-versioning \
        --with-ibm-db2=/home/db2inst1/sqllib --sysconfdir=/etc \
        --enable-force-cgi-redirect --enable-c9x-inline\
make clean
make install
Compiles! Works as a command line interpreter!

Okay I believe this wasn't a PHP error on the compile issue at all since the -L space is nowhere to be found in the config.m4 for DB2.  Marking this as bogus for that part.

As far as the xbithack_handler section goes, you may want to open a new bug with this in mind.
