configure: error: png library not found

[neoslak]

Hi y'all -

For some weird reason I'm having a little trouble compiling Celestia 1.2.5 on my Slackware 9b Linux system. I have GCC 3.2.1. It's an AMD Athlon 650 with a NVidia GeForce2 MX DDR.

I used "./configure --prefix=/usr --with-kde" and I get:
...
...
checking for png_create_info_struct in -lpng... no
configure: error: png library not found

I've got libpng-1.2.5 installed and working with everything else.

The config.log shows:

What could be wrong?

Look at the mix of /different/ png libs in your system. To which one do your header files belong?? You are probably using a too old libpng version, because of this "chaos"...

You must always exercise great care with library upgrades. Deinstall all previous /developer/ versions
before installing a new one (that includes header files!). No problem
with older /runtime/ libs.

Thanks for the reply.

I still don't know how to fix this. I don't even know how this occurred. The only libpng package I thought I had installed was libpng-1.2.5-i386-1 from my Slackware distribution. So I tried uninstalling it and I tried deleting the other libpng* files in /usr/lib and in /usr/include and then reinstalled the libpng-1.2.5-i386-1 package. Now /usr/lib/libpng* shows:

-rw-r--r-- 1 root root 196842 Jan 15 19:50 /usr/lib/libpng12.a
lrwxrwxrwx 1 root root 13 Jan 15 19:52 /usr/lib/libpng12.so -> libpng12.so.0
lrwxrwxrwx 1 root root 19 Jan 15 19:52 /usr/lib/libpng12.so.0 -> libpng12.so.0.1.2.5
-rwxr-xr-x 1 root root 180518 Jan 15 19:50 /usr/lib/libpng12.so.0.1.2.5
lrwxrwxrwx 1 root root 10 Jan 15 19:52 /usr/lib/libpng.a -> libpng12.a
lrwxrwxrwx 1 root root 11 Jan 15 19:52 /usr/lib/libpng.so -> libpng.so.3
lrwxrwxrwx 1 root root 17 Jan 15 19:52 /usr/lib/libpng.so.3 -> libpng.so.3.1.2.5
-rwxr-xr-x 1 root root 180518 Jan 15 19:50 /usr/lib/libpng.so.3.1.2.5

Which looks better but I'm still getting the same error messages when I try to compile Celestia (or, I discovered, other programs such as xawtv that check for libpng). So, this certainly looks like it is not a Celestia problem after all. Sorry for the mis-assumption.
Oh well... I've searched Google, various Slackware sites, even tried to read the libpng man pages and I still don't have a clue where the problem is. Any help appreciated.

I had the same problem too. Apparently libpng needs libz to link right, so setting LIBS=-lz before running configure seems to solve the problem.

[Bohdan]

This is done with the chnage of libpng package. From 1.2.5 it the configuration is based on packagin. This means that all parameters for compilation should be obtained from `libpng-config -libs` which returns `-lpng12 -lz -lm` guys from celestia rely only on -lpng. Thus you can downgrade to some older libpng or guys from celestia should repair their autoconf

Yes now it works. It should be repaired in next version ...
