getopt_long for IRIX

[BSDero]

Hi guys!!

I was playing with my SGI and needed an Irix implementation of getopt_long(), so I got source code from NetBSD and OpenBSD and created a SGI version of it.

I tested an example program of getopt_long() I found in google and all seems works flawlessly , except by a one line change. However the behavior is same than gnu's getopt_long().

I got a tar with sources, header, Makefile and test program, it builds with MipsPro in Irix 6.5. If anybody interested, I would like to share this.

From memory there is/was something about this on the MIPS Pro nekochan wiki page.. if not I intended to put something on there at the same time I wrote the section on work arounds or porting or something like that..

EDIT
oh, wait nup.. that was the senenv/putenv thing .. I did have a solution for getopt_long() which I intended to put in a section after ..

I think I did this when porting hercules IBM mainframe emulator to IRIX.. years ago..

An Implementation of getopt_long is part of gnulib http://www.gnu.org/software/gnulib/MODULES.html#module=getopt-posix. I usually just copy the source files into a suitable directory and add them to the list of .c-Files in the Makefile.

In those GCC-isms related issues I've found *bsd source code easier to port and maintain witrhout all that flags and thinks like that. Source code is way easier to port, clear and maintain.

For anyone who has trouble with getopt_long and IRIX..
I know we have a Wiki on this that says "google around for the example code to implement this" .. which was not very helpful for me.
Granted, once I figured it out, it now seems easy but it took some time for me to get to that point. I want this thread to help anyone else with this problem.

Attached is a tarball with ya_getopt .. Yet-Another getopt implementation.. compiles on IRIX and I tested it already (however not very extensively! so hopefully nothing breaks from this).

Tarball contains:
tar tpf ../getopt_long-in-irix.tar

Code: Select all

getopt_long-in-irix/ya_getopt.c
getopt_long-in-irix/ya_getopt.h
getopt_long-in-irix/libya_getopt.so
getopt_long-in-irix/README

the .c and .h are from ya_getopt. libya_getopt.so is a compiled shared library on IRIX 6.5/mips4 with GCC (we all love GCC right?

The README has some rough notes for anyone who may find themselves in a getopt_long() missing situation and may be clueless as to what to do:

Here is the README (its rough notes.. )

Code: Select all

# These are notes for getopt_lang() in IRIX (GCC)

# Yet Another GetOpt implementation (drop-in)
https://github.com/kubo/ya_getopt

# COMPILE shared library (GCC)
# http://www.cprogramming.com/tutorial/shared-libraries-linux-gcc.html
gcc -c -Wall -Werror -fpic ya_getopt.c
gcc -shared -o libya_getopt.so ya_getopt.o

# LINK with your code (examples)
gcc -Wall -o test main.c -lya_getopt
# LINK with your code specifying .so library directory location
gcc -L/whereis/ya_getopt/ -Wall -o test main.c -lya_getopt

# Copy ya_getopt.h to your source and edit relevant files:
#include "ya_getopt.h"

# Replace getopt_long() calls in your code to ya_getopt_long()

# Example Makefile changes (and/or Environment variable adjustments)
LDFLAGS = -L/usr/nekoware/lib -L/usr/lib32 -L/whereis/ya_getopt/
LIBS = -lya_getopt

# Note:
Ensure libya_getopt.so is stored somewhere where the binary can access
Such as /usr/local/lib/

It does compile with MIPSpro as well:
cc -c ya_getopt.c
cc -shared -o libya_getopt.so ya_getopt.o

Thanks again to Kubo @ https://github.com/kubo/ya_getopt for his ya_getopt code.

NetBSD's pkgsrc has a package with netbsd-compatibility functions that include getopt_long. It's called libnbcompat. This works on IRIX, and might provide other useful things if you are feeling porty.

http://pkgsrc.se/pkgtools/libnbcompat
http://cdn.netbsd.org/pub/pkgsrc/curren ... pat/files/

The files in files/ should be enough to compile and you won't need the pkgsrc tree.
