Problem installing perl modules

[aranes]

Hi all,
I'm having problems installing any perl module via cpanel. It always outputting this error

Hello aranes,

Please check that your /tmp and / are not full on the machine:

df -kh

If they are not full, then try the following:

mv /root/.cpanel /root/.cpanel.bak
/scripts/checkperlmodules --full --force

Thanks!

I am seeing this exact same error on two completely independent hosting companies. This is clearly a bug in cpanel which has been introduced in one of the recent updates.

 

[cPanelTristan]

Actually, if cPanel > Perl Modules area isn't allowing perl modules to be installed, the host is likely disallowing compiler access, preventing installing perl modules entirely at the user level.

WHM > Compiler Access

This sets whether users can use compilers or not. If they are disabled from using a compiler, then the C compiler won't work to install perl modules in cPanel. Your host would simply need to enable compiler access, or they should remove the option to install perl modules in cPanel for accounts.

I'm having the same problem unfortunately, after upgrading cpanel. I came across it after trying to fix the broken language files in cpanel. Google only takes me here and one other page when researching this broken C compiler.

This is the error I get:

Could not compile test....Done
** Unrecoverable Error **

Did you check in WHM > Compiler Access to see if compilers are enabled?

Tristan,i seen it in a few servers too.

Tristan,i seen it in a few servers too.

As Tristan mentioned, this is often the result of compiler access being disabled. Were you able to check to see if that was the case?

Thank you.

 

[theuruguayan]

ACtually. is not the compilers.

Check the permissions of the /tmp folder.

In this particular cases it was set incorrectly so it was not able to create temporary files.

ACtually. is not the compilers.

Check the permissions of the /tmp folder.

In this particular cases it was set incorrectly so it was not able to create temporary files.

For others who may experience the same problem, /tmp should be owned by "root" and have 1777 permissions. The permissions can be set via:

# chmod 1777 /tmp

Thank you.

 

[theuruguayan]

Important to check how it is mounted in /etc/fstab just to be on the safe side.

Create file install.pl:

#!/usr/bin/perl -w

use CGI ':standard';

$msg = `perl -MCPAN -e 'install name_module'`; # example install CGI::Session

print header(), $msg;

Hi

I'm still having this problem.
- Security Center >> Compiler Access -> Enabled
- /tmp folder has the right permissions
- /tmp is not full

- /scripts/checkperlmodules --full --force -> Still errors
- /scripts/upcp --force -> Still errors

Any ideas?

Please submit a ticket at this point using the link in my signature or in WHM > Support Center > Contact cPanel area. Please post the ticket number here for us to follow up on it afterward. Thanks!

I fixed this on a server recently due to /root/tmp/ being a symlink to /tmp/. /tmp/ is set noexec (which may or may not matter), but when I removed the symlink from /root/tmp to /tmp, then did mkdir /root/tmp/ to leave a 755 root:root dir there, the "working C compiler" error went away

Your error said it couldn't locate a gcc binary; I know this is an old post, but you'd want to run 'which gcc' and see if it returns something like /usr/bin/gcc. If it doesn't, you've got some bigger problems, and should use your package manager to re-install gcc. I did this on a centOS system with RPM/YUM by doing:

rpm -e --nodeps gcc --justdb
yum install gcc

you should then be able to run 'gcc -v' and get output like:
[[email protected] ~]# gcc -v

Which user should have compiler access? cpanel?
