[SOLVED] RHEL5 - Install davfs from srpm

RHEL5 - Install davfs from srpm - error with neon 0.30.0

I'm using an old RHEL5 system and trying to install davfs from source. I don't have the option of upgrading the entire system to a newer version, so I am stuck with what I have.

This is what I have tried so far:

Setup rpmbuild environment following the instructions at https://wiki.centos.org/HowTos/SetupRpmBuildEnvironment. Works fine, I can use rpmbuild without needing sudo.
Located the closest match for davfs srpm I could find for the system I am using: http://rpm.pbone.net/index.php3/stat/26/dist/74/size/455789/name/davfs2-1.4.7-8.el6.src.rpm

Downloaded and installed the srpm

$ wget ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/6/SRPMS/davfs2-1.4.7-8.el6.src.rpm
$ rpm -i davfs2-1.4.7-8.el6.src.rpm

Patched the source using included patch files

$ cd ~/rpmbuild/SPECS
$ rpmbuild -bp davfs2.spec
  Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.fxF37X
  + umask 022

  + cd /home/myusername/rpmbuild/BUILD
  + rm -rf davfs2-1.4.7
  + /usr/bin/gzip -dc /home/myusername/rpmbuild/SOURCES/davfs2-1.4.7.tar.gz

  + /usr/bin/patch -p1

  + /usr/bin/patch -p1
  patching file ChangeLog
  patching file src/kernel_interface.c
  patching file src/mount_davfs.c
  + exit 0

Now when I try to build the patched source, I get the error below:

$ rpmbuild -ba davfs2.spec
  ...
  configure: incompatible neon library version 0.30.0: wanted 0.25 26 27 28 29 30
  configure: error: could not find neon
  error: Bad exit status from /var/tmp/rpm-tmp.AFBGNB (%build)

I found a patchfile which indicates this has been fixed and it should build with neon 0.30.0: https://lists.fedoraproject.org/pipermail/scm-commits/Week-of-Mon-20130916/1115037.html. These 2 lines from that page are interesting:
```
# Add support for neon 0.30.0
-%patch1
```

This is where I am stuck. I tried looking at the .patch files included under ~/rpmbuild/SOURCES/davfs2-1.4.7, but couldn't figure out if the patch shown on 1115037.html was included in the srpm. If it was not, how do I update the patch and build it successfully?

I have tried installing davfs binary. It installs fine, but mount fails with SSL handshake error or SSL version mismatch error due to old SSL libraries. This is why I am trying to build from source.

Solution

That line means take the %patch1 line out of the specfile. But if you look lower in the patch, it re-adds it with the -p1 parameter. That patch edits the first patch file and the specfile:

 davfs2-1.4.7-neon-0.30.patch |   47 ++++++++++++++++++++++++++++++-----------
 davfs2.spec                  |    8 +------

So you need to try applying ALL the patches in that email.
