compiling mod_jk

[back2db]

i am trying to connect apache 2 to tomcat 6. i downloaded and tried to compile tomcat-connectors-1.2.26. it compiles and installs /local/apache2/modules/mod_jk.so but when starting httpd, i get

Cannot load /local/apache2/modules/mod_jk.so into server: rtld: 0712-001 Symbol __mcount was referenced\n from module /local/apache2/modules/mod_jk.so(), but a runtime definition\n\t of the symbol was not found.

i read many a post but I did not find out how to compile the module without a requirement for __mcount or how to make it find it.

Your LIBPATH list probably needs an addition:

[tt]:/local/apache2/modules/[/tt]

I am not entirely sure what you mean. during run time, this does not help to find Symbol __mcount and during compile time it does not eliminate the reference to Symbol __mcount

You created a runtime (so = shared object) library. So at run time, httpd needs to be able to locate and reference objects in that library. So the directory that library is in must be in your LIBPATH environment variable I should think.

Thank you for your patience. i do not think that that is the problem, though. (I tried it anyway) .

mod_jk, which is in the library you refer to, cannot load not because it is not found but because it cannot find the runtime reference to Symbol __mcount

OK, after (re-)reading your post again and some googleing, it seems that __mcount is related to profiling. Do you have bos.adt.prof installed?

You are extremely helpful, thanks and you are right.

However, what I wanted was NOT to run profiling but compile mod_jk without it.

I gave up, went to another machine, compiled, copied and am up and running.

Again, thanks.
