Hello, i need the mod_deflate.so compression module for my apache webserver. But if try to load this module it i get: apache2 -f /etc/apache2/httpd.conf Syntax error on line 236 of /etc/apache2/httpd.conf: Cannot load /usr/share/apache2/modules/mod_deflate.so into server: /usr/share/apache2/modules/mod_deflate.so: undefined symbol: inflate others solved this problem by adding LDFLAGS="-lz" in apr-1-config file in the apr source tree what is the right way to add that LDFLAGS setting in ptxdist rule file? Best Regards Oliver
