Thanks a lot for your quick reply.
Zorp 3.0.8 had a problem with newer Python interpreters. I've posted a patch here that should solve the problem.
I guess you are referring to this patch: https://lists.balabit.hu/pipermail/zorp/2008-April/000432.html Which Zorp version should be patched? I tried either 3.1.12 and 3.0.14b both downloaded from here: http://www.balabit.com/downloads/files/zorp/zorp-src/ Quite a few hunks do not succeed. Anyway, I also tried your other proposed solution by using PYTHON=python2.4 ./configure. Sadly I ran into a problem again. Zorp 3.1.12 make fails with the following output: main.c: In function ‘z_set_instance_name’: main.c:222: warning: unused parameter ‘error’ main.c: In function ‘main’: main.c:371: warning: passing argument 1 of ‘z_process_set_argv_space’ makes integer from pointer without a cast main.c:371: error: too few arguments to function ‘z_process_set_argv_space’ make[3]: *** [main.o] Error 1 I also tried to build Zorp 3.0.14b. Make fails with the following output: packstream.c: In function 'z_stream_packet_send': packstream.c:256: warning: implicit declaration of function 'z_data_dump' packstream.c: In function 'z_stream_packet_write_method': packstream.c:313: warning: pointer targets in passing argument 2 of 'z_packet_set_data' differ in signedness packstream.c: In function 'z_stream_packet_ctrl_method': packstream.c:704: warning: value computed is not used packstream.c: At top level: packstream.c:751: warning: missing initializer packstream.c:751: warning: (near initialization for 'z_stream_packet_funcs.set_child') packstream.c: In function 'z_stream_packet_new': packstream.c:768: error: 'Z_STREAM_FLAG_READ' undeclared (first use in this function) packstream.c:768: error: (Each undeclared identifier is reported only once packstream.c:768: error: for each function it appears in.) packstream.c:768: error: 'Z_STREAM_FLAG_WRITE' undeclared (first use in this function) packstream.c:768: warning: passing argument 3 of 'z_stream_new' makes integer from pointer without a cast packstream.c:768: error: too many arguments to function 'z_stream_new' make[3]: *** [packstream.lo] Error 1 I attached the complete output of configure and make of version 3.1.12. Do you have any idea what might cause this error? Maybe I am using a wrong version of some package?
