jpeg support in 5.0.4, (and libs)

[B Squared]

I recently installed PHP 5.0.4 on my Fedora system. I compiled in the GD
option. (--with-gd). Then I tested the ImageTypes() function. It
seems .png and .gif (IMG_PNG and IMG_GIF) are supported, but jpeg
(IMG_JPEG) is not. Is this expected? How do I get .jpeg support?

Out of curiousity, I checked the php-config file in my ../php/bin dir
and here is the libs that are listed:

libs="-lcrypt -lcrypt -lmysqlclient -lpng -lz -lz -lresolv -lm -ldl
-lnsl -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz
-lm -lcrypt "

-lz is listed 6 times, -lcrypt 4 times, -lm 3 times, etc.

Is this really how it should be? I'm guessing listing the libs so many
times doesn't do any harm, but what's the point?

You may have to specifically use --with-jpeg-dir in configure - I've got
"--with-jpeg-dir=/usr" in the configure line I used for building PHP, which
implies at some point I added it on because JPEG support wasn't working.

It's probably just output automatically by the build system, with each
extension adding on all the libraries they depend on, and more than one
requires libz, libcrypto, etc. Presumably the build system doesn't bother
eliminating duplicates, because the linker will anyway.

So I did as you suggested, the jpeg lib was in /usr/lib. I looked at the
configuration output and saw, among other stuff

checking for the location of libjpeg... /usr/lib

checking for jpeg_read_heade r in -ljpeg... yes

and there were no errors, so it looks like it worked. But the
ImageTypes() function still doesn't recognize IMG_JPEG. Any other
suggestions.

Thanks in advance.
