Issue in building Apache 2.2.21 src in AIX 7.1 with GCC.
I am a newbie to apache build process. I have tried to build the apache
v2.2.21 source on AIX 7.1 (with GNU compiler setup) with the following
configure options. The config.log is attached
http://old.nabble.com/file/p32958809/config.log config.log .
./configure --prefix=/var/www/httpd --with-included-apr --enable-proxy
--enable-proxy-ajp --enable-proxy-balancer
The build process fails in the final step of creating the binary for httpd
with an undefined symbol error:
/var/www/src/httpd-2.2.21/srclib/apr/libtool --silent --mode=link

Stop.

I need help on resolving this issue. What is the reason for this failure ??

Am not an expert in the AIX loader. So unable to answer to your query.
These flags are automatically added by configure script & no special
settings is done in the build environment for them to appear.

I did not add these flags.. But on further analysis it appears that there
was an expat header file in the include path which is of version 2.x.x. But
the expat library finally linked though was from Apache src (1.95.x). That
is why this mismatch had happened.
After installing libexpat 2.x.x library separately, I am able to compile the
Apache src cleanly.

But seriously, what is this ^ -- What's -Wl,-uXML_Parse ?
Effectively this is an LDFLAG -uXML_Parse - but what's that do?
Why is it there?
According to:
http://publib.boulder.ibm.com/infocenter/aix/v7r1/index.jsp?topic=%2Fcom.ibm.aix.cmds%2Fdoc%2Faixcmds3%2Fld.htm
-uName Prevents garbage collection of the external symbol Name.
If the specified symbol does not exist, a warning is
reported. You can repeat this flag.
Still doesn't quite make sense. This is C. The chances of something
being garbage collected are near to non-existent.

Why don't you add -bloadmap or -bnoquiet to LDFLAGS and see
what the linker suggests? - Maybe it already knows what's up
