Hi,

I'm a sysadmin living in Montpezat, South France. All our machines here are running CentOS 5, which is an exact clone of Red Hat Enterprise Linux 5. When a program is not available for this distro, I usually use a Fedora Core 6 source RPM to build the actual RPM. That's what I am trying to do now with Celestia. Unfortunately, I get the following configure error:

Code: Select all

Using $(sysconfdir)/gconf/schemas as install directory for schema files
checking for CAIRO_CFLAGS... -I/usr/include/cairo -I/usr/include/freetype2 -I/usr/include/libpng12  
checking for CAIRO_LIBS... -lcairo  
checking for jpeg_start_decompress in -ljpeg... no
configure: error: jpeg library not found

Now the strange thing:

Code: Select all

[root@mediatheque1 ~]# rpm -qa | grep -i jpeg
libjpeg-6b-37
libjpeg-devel-6b-37

What's wrong, doc? Any suggestions?

One last thing:

Code: Select all

[root@mediatheque1 ~]# find / -name 'jpeglib.h'
/usr/include/jpeglib.h

Any suggestions? I'm clueless...

PS: is there some complete dependency list somewhere? I wonder if I need Qt... sometimes dependencies are not explicitly mentioned in SRPMs.

try this
$ " ln libjpeg-6b-37 libjpeg-6b "

in configure

Code: Select all

line 36011 
LIBS="$all_libraries $USER_LDFLAGS -ljpeg6b -lm"
line 36065
 eval "ac_cv_lib_jpeg_6b=-ljpeg6b"

and so on...

Actually, libjpeg-6b-37 is the name of the libjpeg package. Here's what it contains:

Code: Select all

]# rpm -ql libjpeg
/usr/bin/cjpeg
/usr/bin/djpeg
/usr/bin/jpegtran
/usr/bin/rdjpgcom
/usr/bin/wrjpgcom
/usr/lib/libjpeg.so.62
/usr/lib/libjpeg.so.62.0.0
/usr/share/doc/libjpeg-6b
/usr/share/doc/libjpeg-6b/README
/usr/share/doc/libjpeg-6b/usage.doc
/usr/share/man/man1/cjpeg.1.gz
/usr/share/man/man1/djpeg.1.gz
/usr/share/man/man1/jpegtran.1.gz
/usr/share/man/man1/rdjpgcom.1.gz
/usr/share/man/man1/wrjpgcom.1.gz

I can also do this:

Code: Select all

# whereis libjpeg
libjpeg: /usr/lib/libjpeg.so

And to make sure things are configured OK:

Code: Select all

# ls -l /usr/lib/libjpeg*
lrwxrwxrwx 1 root root     17 jun 18 23:17 /usr/lib/libjpeg.so -> libjpeg.so.62.0.0
lrwxrwxrwx 1 root root     17 jun 16 15:19 /usr/lib/libjpeg.so.62 -> libjpeg.so.62.0.0
-rwxr-xr-x 1 root root 135716 jan  6 07:09 /usr/lib/libjpeg.so.62.0.0

So I'm still clueless.

Any suggestions?

You have to look at the /actual/ errors in config.log. The printed errors are often not the actual ones, due to "follow-up" effects.

So look at what happens BEFORE the jpeg test!

jpeg not found errors we had several times already.
E.g.
http://www.celestiaproject.net/forum/viewtopic ... sc&start=0

How about looking FIRST into the powerful search engine of this forum??

Yeah, first thing I did indeed was search the forum. Duly RTFM'ed, but to no avail. Looks like most of the guys simply forgot to install according -devel packages.

Now I'm at home on a Debian machine, but tomorrow I'll get back to work and have a look at the configure log file. I'll report that back then.

Q: is there a somehow complete list of Celestia build dependencies? Libs and versions? That would help.

Cheers,

Niki

As Fridger stated above, your errors may have nothing to do with the jpeg libs. If I remember correctly, I was getting similar errors a while back. The cure was an up to date gettext package. I think.
