[PHP-DEV] PHP 4.0 Bug #7210: libpng not properly detected From: mlong <email protected>
Date: 10/14/00

From: mlong <email protected>
Operating system: tru64 5.0 (OSF/digital unix)
PHP version: 4.0.3
PHP Bug Type: Compile Failure
Bug description: libpng not properly detected

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
