Solaris

Hello there.
I have solaris 10 installed on a sun ultra 10 machine. I recently installed the gcc compiler suite from sunfreeware .

I was assuming that there was no C compiler installed with the solaris installtion by default. I checked this by typing gcc in the console only to find it saying command not found. Hence I installed the compiler suite and I thought now i have it taken care of.

Recently while trying to build the mplayer from source i stumbled upon a post
that updates the links to the gcc compiler and the gmake utility. This struck me that perhaps i might already have had the C/C++ compiler installed on by default. Just that it was not in the path and hence was not able to run when i typed gcc -v in the console.

Being curios I again tried the command gcc -v and this is what i got on the console:

Code:

Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with: /gates/sfw10/builds/sfw10-gate/usr/src/cmd/gcc/gcc-3.4.3/config
ure --prefix=/usr/sfw --with-as=/usr/sfw/bin/gas --with-gnu-as --with-ld=/usr/cc
s/bin/ld --without-gnu-ld --enable-languages=c,c++ --enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

And i checked out the sunfreeware site again and it said the gcc compiler suite should get installed in /usr/local/. So now i see that there is another binary file called gcc located in /usr/local/bin/ and on executing /usr/local/bin/gcc -v this is what i get:

Code:

Reading specs from /usr/local/lib/gcc/sparc-sun-solaris2.10/3.4.6/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/l
d --enable-shared --enable-languages=c,c++,f77
Thread model: posix
gcc version 3.4.6

So it means that the version of the gcc compiler that gets invoked when i type gcc on the console is the one from /usr/sfw/lib/ and not from /usr/local/lib/ as in my path the former comes before the latter.
SO how do I uninstall the latter one? Do i even need to uninstall the latter one?

The latter one has a later version than the former one. Is there a way to tell the whole system that i want my default C/C++ compiler to be the latter one and not the former one?

If you see the post that i mentioned above, the person has done the following two things:

Code:

 
ln -s /usr/sfw/bin/gmake /usr/bin/make
ln -s /usr/sfw/bin/gcc /usr/bin/cc

Does doing these tell the system that my "default" C/C++ compiler is the one at /usr/sfw/bin/?
In my own case can i replace /usr/sfw/bin/gcc with /usr/local/bin/gcc? With regards to make, the "default" make utility found on my machine it seems is the one at /usr/ccs/bin/ . And then there is a gmake utility at /usr/sfw/bin/. So i can differentiate between make and gmake just by their names.

so do i need to make the symbolic links shown above or can i just ignore the fact that I now have two versions of the gcc compiler and two versions of the make untility. Im sure the gcc compilers are the GNU ones as sun does not ship its own compilers alongwith solaris 10 or does it? The make utility is from Sun and the gmake utility is obviosuly the Gnu variant.

I hope to hear from you people,

When I build something I explicitly specify the compiler using CC=/usr/local/bin/gcc or whatever to ensure I use the appropriate compiler.

Also, seriously consider using Sun's Studio11 with Solaris 9 or above rather than gcc.

/usr/sfw has been discussed at length on opensolaris.org. But I didn't know that it's currently an official part of the OS. Does everyone else have /usr/sfw too?

Anyway the idea behind /usr/sfw is that it follows the model of /usr/ucb, /usr/xpg4, /usr/xpg5, etc. By fiddling with your PATH, you can decide which versions of various programs you use. /usr/sfw (which perhaps should have been called /usr/gnu) is supposed to skew everything to the gnu utilities. This "duplicity" has been a part of Solaris for quite a while. All that is happening is one more "standard" (well, gnu hates that term, "paradigm" maybe?) is being tossed into the mix.

Well..i installed the whole 5 CD set except the sendmail feature as I knew it gives problems later and i wudn't even use it anyways.

I haven't seen the studio 11 or any such thing on my system. Perhaps you may be referring to the additonal DVD tht gets shipped with the original OS release. May be that contains the required compilers and other utilities.

Anyway, would anyone please look at the post that i mentioned a link to and let me know if i need to update the links as the original author has done?.

Ive left a question there as well, but id like to hear from you guys as well...

REgards,

You have to deliberately install it from media or a download.

I have not had to update such links and I use both Studio11 and sunfreeware's gcc on my system.

Great. I would soon try to see if I can build my own mplayer on my sparc machine and would post the details here. has any one of you tried that before? The author has narrated the steps for his 64 bit machine which isn't a sparc so I am a bit confused with regards to the crle command that he mentions somewhere in the middle of the post.

Does any one have any idea as to what that command actually does and do i need to execute that command for a sparc machine too?

Hoping to hear from you guys,

crle has a man page
