Linux and Erlang install

I just tried a yum install erlang, and got the following


--> Finished Dependency Resolution
erlang-odbc-R14B-04.1.el5.x86_64 from epel-erlang has depsolving problems
  --> Missing Dependency: libodbc.so.1()(64bit) is needed by package erlang-odbc-R14B-04.1.el5.x86_64 (epel-erlang)
wxGTK-2.8.12-1.el5.x86_64 from epel has depsolving problems
  --> Missing Dependency: libSDL-1.2.so.0()(64bit) is needed by package wxGTK-2.8.12-1.el5.x86_64 (epel)
Error: Missing Dependency: libodbc.so.1()(64bit) is needed by package erlang-odbc-R14B-04.1.el5.x86_64 (epel-erlang)
Error: Missing Dependency: libSDL-1.2.so.0()(64bit) is needed by package wxGTK-2.8.12-1.el5.x86_64 (epel)
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
[root@rhel yum.repos.d]#

How can I install these dependencies ?

I think you should consult the Fedora EPEL project pages.

This one

http://fedoraproject.org/wiki/EPEL

says in regard to RHEL and dependencies:

You need to also enable the 'optional' repository to use EPEL packages as they depend on packages in that repository. This can be done by enabling the RHEL optional subchannel for RHN-Classic. For certificate-based subscriptions see RHEL Deployment Guide.

Here is how to enable an additional subchannel:

https://access.redhat.com/knowledge/solutions/11312

And this is the part of the Deployment Guide on supplementary repositories:

http://rdsrc.us/sjzdtd

The guides gave the following example:

[root@server ~]# yum repolist all
repo id                      repo name                           status
rhel-6-server                Red Hat Enterprise Linux 6Server -  enabled
rhel-6-server-beta           Red Hat Enterprise Linux 6Server Be enabled
rhel-6-server-optional-rpms  Red Hat Enterprise Linux 6Server Op disabled
rhel-6-server-supplementary  Red Hat Enterprise Linux 6Server Su disabled

Select allOpen in new window

From which I could either perform

yum-config-manager --enable rhel-6-server-optional-rpms

Select allOpen in new window

or

yum install rubygems --enablerepo=rhel-6-server-optional-rpms  // for rubygems

Select allOpen in new window

So I went to my system and found

[root@rhel yum.repos.d]# yum repolist all
Loaded plugins: rhnplugin, security
repo id                repo name                                  status
epel                   Extra Packages for Enterprise Linux 5 - x8 enabled: 7,228
epel-debuginfo         Extra Packages for Enterprise Linux 5 - x8 disabled
epel-erlang            Erlang/OTP R14B                            enabled:   238
epel-erlang-source     Erlang/OTP R14B - Source                   disabled
epel-source            Extra Packages for Enterprise Linux 5 - x8 disabled
epel-testing           Extra Packages for Enterprise Linux 5 - Te disabled
epel-testing-debuginfo Extra Packages for Enterprise Linux 5 - Te disabled
epel-testing-source    Extra Packages for Enterprise Linux 5 - Te disabled
rhel-debuginfo         Red Hat Enterprise Linux 5Server - x86_64  disabled
rhel-debuginfo-beta    Red Hat Enterprise Linux 5Server Beta - x8 disabled
repolist: 7,466
[root@rhel yum.repos.d]#

Select allOpen in new window

So I do not see an 'optional' repository.

Is there a way to get an 'optional' repository, and how can I get one ?

Could it be that your subscription is incomplete?

You could try "subscription-manager" or "subscription-manager-gui" to check.

Do you use RHEL Classic channels or RHEL Certificate-based product certificates?

If Classic, did you look here?

https://www.redhat.com/wapps/sso/login.html?redirect=https%3A%2F%2Frhn.redhat.com%2Frhn%2Fsoftware%2Fchannels%2FAll.do

I don't have an RHEL entitlement, so I can't give any further detail.

If anything fails you can of course try to install the libraries for CentOS/Fedora.

This is libodbc: (CentOS):
http://rpmfind.net/linux/rpm2html/search.php?query=libodbc.so.1&submit=Search+...&system=centos&arch=

This is libSDL (Fedora):
http://rpmfind.net/linux/rpm2html/search.php?query=libSDL-1.2.so.0&submit=Search+...&system=fedora&arch=

This is libSDL (CentOS):
http://rpmfind.net/linux/rpm2html/search.php?query=libSDL-1.2.so.0&submit=Search+...&system=centos&arch=

I tried the following but it did not work

[root@rhel yum.repos.d]# subscription-manager
bash: subscription-manager: command not found
[root@rhel yum.repos.d]#
[root@rhel yum.repos.d]# subscription-manager-gui
bash: subscription-manager-gui: command not found
[root@rhel yum.repos.d]#

Did I perform that correctly ?

Also, how do I tell if I use RHEL Classic channels or RHEL Certificate-based product certificates?
