Stop.

We have also installed the below version GCC compiler for AIX 6.1:-

libgcc-4.2.0-3.aix6.1.ppc.rpm
libstdcplusplus-4.2.0-3.aix6.1.ppc.rpm
libstdcplusplus-devel-4.2.0-3.aix6.1.ppc.rpm
gcc-cplusplus-4.2.0-3.aix6.1.ppc.rpm
Kindly suggest as to what is missing here that is causing the error.

Did you read and understand the error message?? You're missing the pcre.h library...so install it. On Linux it's libpcre, not sure what it's called on AIX. But it sure seems like you might, based on this:
https://www.ibm.com/developerworks/c...e-d699b5c75b81

...where you were told on the IBM forums to install the pre-built apache package, and were even told to install the pcre development package, seven days ago.

Hi ramkishan,

I agree with TB0ne that the easiest solution is usually to install the prebuild package, preferably from IBM at https://www-03.ibm.com/systems/power...x/alpha.html#H.

You could also try Michael Perzl's version at http://www.perzl.org/aix/index.php?n=Main.Apache.

If for some reason you really need to build your own version (possibly because you need a module that's not included in the prebuilt versions), I'd start with Michael's website, where he makes his RPM SPEC files available, together with instructions for how to build his packages. I usually find it easier to customize those than to build from scratch.

Good luck!

@OP: If you had installed pcre from source, you would have /usr/local/include/pcre.h
Or maybe the installation failed or you specified wrong options. Please also read this: http://web.axelero.hu/lzsiga/aix-linking.html#Q0007
And this: http://web.axelero.hu/lzsiga/aix-linking.html#Q0025

Also I hope it is '2.4.27' not '2.4.2'. Before httpd, install apr-1.6.2 and apr-util-1.6.0
