httpd crashes with segmentation fault: Incompatible libpng version in application and library
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

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

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 ?

Re: httpd crashes with segmentation fault: Incompatible libpng version in application and library [In reply to]
Hi,

you can check if you use prelink feature. In such case, LD_LIBRARY_PATH is
overwriten by LD_PRELOAD or prelink.

Re: httpd crashes with segmentation fault: Incompatible libpng version in application and library [In reply to]
Hi,

Thank both of you for reply.

I finally discovered that this problem occurs at the stage of linking. The
gd library has hard-coded that only libpng 1.2.x series can be recognized.
Since its configure script cannot find libpng12-config from my libpng 1.5.x
install path, it uses the one under /usr/bin instead.

Regards.
