Celestia Forums

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

-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.

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 ...
