Error with GCC: while loading shared libraries: libisl.so.22: cannot open shared object file: No such file or directory


Hello,

I'm tooling around on my Slackware 14.2 machine tonight, trying some beginner C programming. I encountered the following error when trying to compile my first program:

/usr/libexec/gcc/x86_64-slackware-linux/9.3.0/cc1: error while loading shared libraries: libisl.so.22: cannot open shared object file: No such file or directory

I imagine this is a fairly standard error. The library, libisl.so.22 is located at /usr/lib. I added this directory to my ld.so.conf file and ran ldconfig. This didn't help.

Running ldconfig -p shows the library in the appropriate directory.

I should note this is a 64-bit machine. It's been a while since I set it up, so I've forgotten the finer points of the system.

I'm fairly sure the answer is found in this multilib setup.

Thanks in advance...

Here is the output of the command gcc -v:

14.2 doesn't use gcc 9.3.0
Did you installed gcc from current into stable?

I don't remember. It's been a while since I set up the machine. I did add multilib capability as described on this page: http://docs.slackware.com/slackware:multilib

Probably you mixed up your system with Slackware-Current
check your mirror setting in /etc/slackpkg/mirrors

These are the relevant lines from my mirrors file:

# Slackware64-14.2

# USE MIRRORS.SLACKWARE.COM (DO NOT USE FTP - ONLY HTTP FINDS A NEARBY MIRROR)
http://mirrors.slackware.com/slackwa...ckware64-14.2/

http://hpc-mirror.usc.edu/pub/linux/...ckware64-14.2/

It would seem I uncommented 2 lines. I don't know if this will make much difference, but it is mentioned in the file notes. I will comment out the mirror from usc.edu

This looks like you downloaded the gcc multilib packages for Slackware-current and installed those packages.

The /usr/lib/libisl.so.22 should be a 32-bit library.
Do you have got a /usr/lib64/libisl.so.22 too?

Furthermore both gcc 9.3 and isl-22.1 are packages for -current, not for 14.2

PS: -current is often referred to as 14.2+ (note the PLUS) but is at the moment closer to the "to be released" 15.0 version then the almost 4 year old 14.2 one of Slackware.
Packages for -current are not compatible with 14.2 anymore.

All of the mirrors under Slackware64-current in my slackpkg mirrors file are commented out. I've been using the Slackware64-14.2 mirrors for a while. I have set it to a single mirror, from texas.edu.

This would seem to contradict my downloading Slackware-current packages. It is possible I used the "current" mirror during initial set up.

I don't have /usr/lib64/libisl.so.22.

I'm old enough to remember that summer Slackware 14.2 was released. Cc1 didn't have dependancy on isl. You messed up the system with newer gcc from -current.

libisl should be provided by the isl package in the l/ series on -current. gcc is looking for the 0.22.1 version of isl, which is version in -current right now. That means the gcc you're using is from -current (or multilib for -current).

If you're running a 14.2 install, isl is not included (it was added to -current in Sep 2019).

So, there's 3 different things it could be (in the order I believe to be the most likely to the least likely).

1. You're running 14.2 but installed the multilib packages for -current (which is what Alien Bob suggested above).
2. You're running an incomplete version of -current and missing the isl package.
3. You're running an partially out-of-date version of -current and have the older 0.21 version of isl.

To figure this out, can you provide us the output of the following command?

Code:
ls -l /var/log/packages/{aaa,gcc}*

Please define "for a while." Did you used to be on -current, and then try to switch back to 14.2? That's ... fraught with danger.

Despite your claim of running 14.2, you have the -current multilib gcc. Get the correct multilib files from here:

http://bear.alienbase.nl/mirrors/peo...multilib/14.2/

And simply use upgradepkg to switch to the correct version.

I'll refrain from giving slackpkg advice as I don't use it.

Please don't mix -current and 14.2 packages!
