rpm2cpio

archtam · 2005-11-11 19:15:43

I just moved to Arch from Debian and therefore I am still learning my way out to get myself accustomed to Arch. Anyway, I am tryin to install fortran compiler and i found some helpful topics posted by generous people. I used their pkgbuilds and unfortunately i am having problems with this "rpm2cpio" dependency. And it bombs on me sayin it cant find this. Tried to look out where it is available, but as i said Im not yet fortunate on working it out the easier way.

Help is much appreciated.

Thanks,
Arch (i moved to Arch cos of the reason that my nickname is Arch too..lol. Feels great to have my desktop say ArchLinux )

you need rpmunpack It is in main repo - replace rmp2cpio with rpmunpack

archtam · 2005-11-11 20:20:24

Thank you all. I guess I will try the "rpmunpack" first. Seems like it should be fairly easy. If it doesnt work, i will try the other one.

So far, I am glad to have this great distribution on my laptop. Its faster then others I have been using so far. However I wanna add another question here.....Everytime I reboot, I need to perform "alsaconf" to enable my sound. I dont know why, I have added alsa in my Daemons in /etc/rc.conf, but it doesnt seem to do anything when i start xmms. Its not something big which I cant do, but it would be good to know if I am missing sth here.

Thanks again !

PS - And I am used to using "/etc/init.d/whatever start", in Arch "init.d" is "rc.d" i think. So anyways, its coming slowly. Good to see an active forum after a long time, unlike debian (No offense to those who like debian)

dtw · 2005-11-11 20:25:23

Yeah, resist the urge to tack questions on - please make a new thread with your new question - and try searching first too - it makes life easy for everyone!

archtam · 2005-11-11 20:31:56

Alright, thanks anyways.

I figured it out.

Okay seems like I installed rpm2cpio successfully. So I proceeded to install intel fortran compiler and this is what i get :

# makepkg PKGBUILD
==> Making package: ifc9 9.0.021-1 (Fri Nov 11 14:55:00 CST 2005)
==> Checking Runtime Dependencies...
==> Checking Buildtime Dependencies...

requires: rpm2cpio
==>

After this, I tried to search for "rpm2cpio" using

# find / -name rpm2cpio

but didnt display any results.

I am wondering if I did install rpm2cpio correctly, or may be i need to link something in /usr/bin ?

archtam · 2005-11-11 21:07:03

my bad, i also did this after makepkg

pacman -A rpm2cpio-1.2-1.pkg.tar.gz

No luck either
