While porting changes from Linux to AIX, I faced problem w.r.t getopt_long() function.

I am using AIX 6.1.

GCC version :

Using built-in specs.
Target: powerpc-ibm-aix6.1.0.0
Configured with: ../gcc-4.4.6/configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --enable-languages=c,c++,fortran --prefix=/opt/freeware --enable-threads --enable-version-specific-runtime-libs --disable-nls --enable-decimal-float=dpd --host=powerpc-ibm-aix6.1.0.0
Thread model: aix
gcc version 4.4.6 (GCC)

Also I came across article in IBM's technical library "Command Line Processing with getOpt()" where I can understand that I can use function getopt_long() on AIX as well.

http://www.ibm.com/developerworks/aix/library/au-unix-getopt.html

Question :

Linux's getopt.h is part of AIX's unistd.h with an exception of getopt_long().

During comilation, I get an error "error: 'getopt_long' was not declared in this scope".

Please guide me, How can I reslove this issue.

Thanks.

How did you manage to get the getopt.h file in AIX? I followed the link you have mentioned, but it doesn't list any steps to get the getopt.h file.

Did you have to install some rpms?

 

On my AIX box, I couldn't find this .h file anywhere. Here are my compiler versions.

/opt/IBM/xlc/13.1.2/

-bash-4.2$ gcc --version
gcc (GCC) 4.8.3

 

Any info would be appreciated.

Hi Amar,

 

getopt_long() is not available with AIX. 

Even the below article which you referred also talks in general about UNIX, but it doesn't mention that getopt_long() works on AIX.

Hope this helps you.
