Thanks for your reply.

I've tried he first method before, no luck.

For the second one, I cannot find any useful information about the 'FileLoad' directive, neither from Google nor the official documentation.

Are you sure you didn't misspell the directive ?

Two things that come to my mind atm:

1. Link the existing “libpng.so” installed to the one you compiled
or
2. Try using FileLoad directive in the httpd.conf to load the correct "libpng.so" file

Hi,

I've compiled httpd 2.2.21 and php 5.3.10, the version of libpng I used is 1.5.7, and I installed all the three packages under a custom path under /opt.

The OS is CentOS 6.2, which contains an official distribution of libpng, the version is 1.2.46.

When I start the server and visit programs hosted on it, the error.log keeps being appended with the following messages:

libpng warning: Application was compiled with png.h from libpng-1.5.7
libpng warning: Application  is  running with png.c from libpng-1.2.46
gd-png:  fatal libpng error: Incompatible libpng version in application and library


I know the reason is that the version running with is not the one compiled with. But setting the environment variable LD_LIBRARY_PATH won't solve the problem.

Can anybody tell me how to fix this ? I know removing the old version of libpng or recompile the server using the old version may be ok, but there are some other potential problems, so I just want to run my application server with the new version of libpng compiled by my self.

Thanks
