emacs 24 build from source and VL 7

[YellowGranite]

I just installed VL 7 and am putting my desired apps in place. I tried to build emacs and found that the configure script complained about libjpeg not being at version 6b or later. However, what I observe is that libjpeg is at version 8. So I am stumped by this. Anyone know about this?

Output from configure:

Code:

configure:11401: WARNING: libjpeg found, but not version 6b or later

What is installed:

Code:

>ls -l /usr/lib/libjpeg*
-rw-r--r-- 1 root root 253946 Jan 16  2011 /usr/lib/libjpeg.a
-rwxr-xr-x 1 root root    914 Jan 16  2011 /usr/lib/libjpeg.la*
lrwxrwxrwx 1 root root     16 Aug 15 08:15 /usr/lib/libjpeg.so -> libjpeg.so.8.0.1*
lrwxrwxrwx 1 root root     16 Aug 15 08:15 /usr/lib/libjpeg.so.8 -> libjpeg.so.8.0.1*
-rwxr-xr-x 1 root root 213912 Jan 16  2011 /usr/lib/libjpeg.so.8.0.1*

Note that there were some version 62 files in /usr/lib, I moved them and then reinstalled libjpeg with gslapt. These were the files I moved:

Code:

lrwxrwxrwx 1 root root     17 Aug 13 13:17 libjpeg.so.62 -> libjpeg.so.62.0.0*
-rwxr-xr-x 1 root root 126528 Mar 21  2011 libjpeg.so.62.0.0*

Does that mean there are still remnants of version 6.2 around? How do I get rid of that? Is it needed?

Hi Kevin,

We have some old versions of libjpeg for backward compatibility. You can remove the old ones safely. This decision is being revised for the future since those old libs are not needed anymore.
Alternatively, we have new Emacs packages in our untested pool. You need to update imagemagick from the extra repo. The usual warning, be careful because this one is from untested. Here is the link anyway, you can install it with installpkg as root:

http://vlcore.vectorlinux.com/pkg/untested/veclinux-7.0/x86/emacs-24.1-i586-2vl70.txz

Let us know how it goes

Hi rbistolfi,

Thanks for the reply. I have downloaded/installed the test version of emacs 24.1 and it works fine. I haven't noted anything that is broken, yet.

My source tree for the latest emacs must have gotten corrupted from my attempts to build it with the older libjpeg files in place, such that it would not get beyond that error even when I moved the libjpeg files. However, with a fresh bzr checkout, I found that I did not encounter that error. So, I have emacs 24.2.50.1 up and running. Thanks for the help.

Glad you got it working, enjoy!
