I want to install Libssh2 so i can use the ssh exec via PHP as a certain user. I have an Centos 4.4 running. I followed the tutorial on PHP.NET but i had no succes. I couldn't even compile. Everything was ok during the configure but during the MAKE I always get following error Code: gcc: /usr/include: linker input file unused because linking not done channel.c:1253:10: /usr/include: No such file or directory channel.c:71: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugzilla.redhat.com/bugzilla> for instructions. ... Next I try to installe an RPM from the DAG repo again no succes. Code: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/ssh2.so' - /usr/lib/php/modules/ssh2.so: undefined symbol: zend_hash_add_or_update in Unknown on line 0 Is there anybody who got it working on a Centos 4.4 with apache 2 and PHP5 (installed through yum via centosplus repo) Any help or pointers are welcome.
