[PHP-DEV] PHP 4.0 Bug #7210 Updated: libpng not properly detected From: Bug Database (php-dev <email protected>)

I'm afraid we don't have the resources to track if and when this problem is fixed in libpng. This means that any interim hack we could include with PHP now would probably stay and litter the tree indefinitely.

Please send a mail about this to the php mailing list. That way it can be found from the list archives by people who encounter the problem.

Thanks.

This is a problem with libpng but until it is changed you might want to make PHP aware of this issue and to compensate accordingly.

Under Tru64 UNIX (Digital UNIX/OSF) there is a slight problem in it finding the libpng library.

The solution is this:
cp /usr/local/lib/libpng.so.2.1.0.8 /usr/local/lib/libpng.so

You might want to put this in the make install since it could easily throw off someone and take a while for them to figure out.

The particular problem I was running into was compiling apache which included php4 which included gd which included libpng:
at-lite/libexpat.a -Wl,-rpath,/usr/local/lib -L/usr/local/lib -Lmodules/php4 -
L../modules/php4 -L../../modules/php4 -lmodphp4 -lpng -lz -lgd -lresolv -lm -
lresolv -lm
