CAUTION: This e-mail originated outside the University of Southampton.

I just read again the following note mentioned in the documentation and realized that even if perl-XML-LibXSLT is installed using CPAN it also generates an httpd segmentation fault. So does this mean that we can go ahead and install perl-XML-LibXSLT using dnf and just apply the below fix to resolve the segmentation error?

Kindly confirm.

Compatibility issues with XML::LibXSLT

Installing XML::LibXSLT either through the perl-XML-LibXSLT or through CPAN causes httpd to generate a segmentation fault when you try to start it. The most straightfoarward solution to this is to run httpd in mpm-prefork rather than mpm-event mode. This can be acheived by editing /etc/httpd/conf.modules.d/00-mpm.conf and commenting out the following line:

LoadModule mpm_event_module modules/mod_mpm_event.so

and uncommenting the mpm-prefork line:

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

Thanks

Maher

I believe in doing things properly, so I'll spin up a VM with Redhat 8.6 at some point today (or more likely this evening as it's looking like a busy day) and try and replicate what you're experiencing here.

You had no problem with the dnf perl bindings installation,

and only with the cpan installs,

from what I gather.

John's mentioning of version numbers reminds me - you can use cpan or cpanm to install specific versions of modules too.

If there's a known version that works well with your RedHat 8.6, you could ask cpan or cpanm to specifically install that version.

This is assuming I'm not confusing Perl Module versions with underlying lxslt versions.

I once had a problem running Alien::ImageMagick on an older version of CentOS, and found it was attempting to install a version of ImageMagick not compatible with my OS, so I just jumped into the part of the cpan module that specified what version of ImageMagick to install, changed it to a last known working version, and that solved the problem, giving me a uniquely patched version of the cpan module to install to solve my particular issue.

Of course in this case, the error we're facing is it not being found. Which means there's a risk it could be there and working and just not being located.

Obviously I'm only speculating and could be completely wrong.

I'll replace hypothetical guessing with experience and results from trial and error,

when I get the VM going later today.

Of course, the problem could be something unique to your setup Maher, that I may not be able to initially replicate with a VM, and might be able to replicate with further communication with you. For now, I'll give it a go later today, and see what I find, then I'll post back here and share any findings.

Feel free to experiment with other potential solutions in the meantime.

Or take a break if it's driving you potty ;-).

Yours,

Andrew.

Newer versions of cpanm apparently allow you to do this (I've never tried this before!):

Does that help at all?

I personally haven't tried running EPrints on RHEL8. Others might be able to answer that question.

Then we did a dnf remove perl-XML-LibXSLT and then a cpanm (Yes we are using cpanm) XML::LibXSLT but received the same error and the installation failed.

Could the issue be from the location of the libxslt file?

If you try installing from RPM:

Does it work (and resolve dependencies)?

If so, you could then remove the RPM version:
>dnf remove perl-XML-LibXSLT --noautoremove

and then try installing the CPAN version again.

Another thing you could try is using ‘cpanm’ – an alternative to CPAN.

Hi Martin

The packages libxslt-devel libxslt libxml2-devel libxml2 are only installed using dnf and are not installed again on the system using CPAN. As for the XML::LibXSLT it is recommended in the documentation to install it using CPAN and not as an rpm using dnf.

Any ideas?

Thanks,

Hi,

Hi Maher,

I don’t have a RHEL8 box nearby right now, but I’d check that the libxml2 and libxslt packages are installed on the server.

> dnf install libxml2 libxslt

These are requirements for the perl modules you are trying to add.

Cheers,

John

We are in the progress of migrating our EPrints 3.4.1 system from Rehat Linux 7.6 server to a Redhat Linux 8.6 server. We have successfully installed all of the required packages but are having issues installing the XML::LibXSLT package. As recommended in the documentation this package should be installed using CPAN. However using CPAN we are receiving the following error:

Searching XML::LibXSLT () on cpanmetadb ...

--> Working on XML::LibXSLT

Fetching http://www.cpan.org/authors/id/S/SH/SHLOMIF/XML-LibXSLT-2.002001.tar.gz

Try setting LIBS and INC values on the command line

Or get libxslt and libxml2 from

If you install via RPMs, make sure you also install the -devel

RPMs, as this is where the headers (.h files) are.

-> N/A

-> FAIL Configure failed for XML-LibXSLT-2.002001. See /root/.cpanm/work/1695296840.123696/build.log for details.

Any idea how to fix this issue?

Thanks,

Maher

Sorry the libxslt is a folder (not a file) and is located here:

/usr/include/libxslt

We also have the following libxslt files here:

/usr/lib64/libxslt.so.1.1.32

/usr/lib64/libxslt-plugins

/usr/lib64/libxslt.so.1

/usr/lib64/pkgconfig/libxslt.pc

/usr/lib64/libxslt.so

/usr/share/licenses/libxslt

The error appearing when trying to install using CPAN is this:

looking for -lxslt... no

libxslt not found

We installed from RPM dnf install perl-XML-LibXSLT which was successful and resolved any dependencies.

Then we did a dnf remove perl-XML-LibXSLT and then a cpanm (Yes we are using cpanm) XML::LibXSLT but received the same error and the installation failed.

Could the issue be from the location of the libxslt file?

# which libxslt

/usr/bin/which: no libxslt in (/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

The libxslt file is located here:

/usr/include/libxslt

Thanks

Apologies, that previous ‘which’ wasn’t too helpful :\

If you try installing from RPM:

>dnf install perl-XML-LibXSLT

Does it work (and resolve dependencies)?

If so, you could then remove the RPM version:
>dnf remove perl-XML-LibXSLT --noautoremove

and then try installing the CPAN version again.

Another thing you could try is using ‘cpanm’ – an alternative to CPAN.
