Subject Re: [users@httpd] httpd crashes with segmentation fault: Incompatible libpng version in application and library
Date Tue, 20 Mar 2012 01:10:26 GMT
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.
