Can't compile ClanLib on OpenBSD

[zmyrgel]

Hi,

I can't get the ClanLib to compile on OpenBSD-current or -4.2.

On both systems the configure script fails as it can't find the png although it's installed.

Any suggestions on how to get ClanLib to compile?

Ensure that the PNG development package is installed, not just the libpng library.

If that does not work, have a look at: http://clanlib.org/docs/clanlib-0.9.0/overview/install-linux-gcc.html

This is how I install ClanLib 0.9 on linux.

Ok, posting more info.

configure goes through if I don't give any extra options for it besides the --prefix option but the compiling fails:

As far as png goes, I've installed the png-1.2.18 and it installs following files:
bin/libpng-config
include/libpng/
include/libpng/png.h
include/libpng/pngconf.h
lib/libpng.a
lib/pkgconfig/
lib/pkgconfig/libpng.pc
@endfake
@man man/cat3/libpng.0
@man man/cat3/libpngpf.0
@man man/cat5/png.0
share/doc/png/
share/doc/png/libpng-${VERSION}.txt


I think the OpenBSD doesn't slice packages to separate dev-packages as Debian does.

And here's the gcc:
gcc version 3.3.5 (propolice)

I used following when it complains about the missing png:

./configure --enable-clanDisplay --enable-clanGL --enable-clanSDL --enable-clanSound --enable-clanNetwork --enable-clanGUI --enable-clanVorbis --enable-docs


The png and other external libs are all installed to /usr/local but I don't think that should affect the install process.

It looks like IOData/Generic/inputsource_file.cpp is missing a "#include <unistd.h>"

I do not use OpenBSD or ClanLib 0.8. (i use Clanlib 0.9)

I am not sure why configure is rejecting png, it looks like "Setup/Tests/png.cpp" is failing. Try compiling that file manually, and see if it works.

(Also ensure that you are using the SVN of 0.8)
