Re: mod_jk linking problems: Tomcat 3.2.1, FreeBSD 4.2 - problems with Makefile?

[Dave Smith]

I got it running on FreeBSD 4.0 using jdk1.1.8. Should be similar with
1.2 native, also on linux 6.2 with jdk1.3. 

The process is explained in some detail in the mod_jk.so how-to in the doc
folder of the source distro. (or on line in the tomcat documentation).  You did
read the documentation, right? ;-)

If you need more help I explained what I did and this is posted, should be easy
to find in the tomcat-user archives by searching on FreeBSD.

 Hi.  I'm trying to get tomcat working with the following versions:
 
 jakarta-tomcat-3.2.1
 FreeBSD-4.2-RELEASE
 apache-1.3.14
 jdk-1.2.2-beta (native freebsd build)
 
 I haven't yet tried to run this all under linux emulation, and would rather
 not.
 
 The problem I've been having is that Apache won't load mod_jk.so because of
 undefined linker symbols.  At first this was "fdatasync".  I looked over the
 tomcat-user mail archive and found a thread that seemed to relate to this
 from
 last December, at:
 
   http://mikal.org/interests/java/tomcat_users/msg18074.html
 
 ...therein, "AC" notes a section in jk_util.c that has ifdef sections for
 ddifferent operating systems, to wit:
 
 #ifndef WIN32
 #ifndef FREEBSD
 #ifndef NETWARE
 fdatasync(fileno(p-logfile));
 #endif
 #endif
 #endif
 
 Scrutinizing Makefile.freebsd more closely, I discovered that it defines
 
 CFLAGS=-DHAVE_CONFIG_H -g -fpic  -DSHARED_MODULE -O2 -D_REENTRANT -pthread -
 DLINUX -Wall
 
 Note the -DLINUX.  I changed this to -DFREEBSD and came up with a new link
 error
 upon starting apache:
 
 Cannot load /usr/apache/libexec/mod_jk.so into server:
 /usr/apache/libexec/mod_jk.so: Undefined symbol "pthread_mutex_unlock"
 
 I've tried defining both FREEBSD and LINUX, and I've tried
 deleting -pthread, to
 no effect.
 
 Can anyone help me with this?  I'm not too up up how to go about handling
 thread
 libraries on FreeBSD, and moreover the parameters in the Makefile seem to be
 incorrect.  Is there a more recent Makefile.freebsd I could use, or could
 somebody
 mail out a functioning one?
 
 TIA,
 Tim

RE: mod_jk linking problems: Tomcat 3.2.1, FreeBSD 4.2 - problems with Makefile?

[Tim Gilbert]

Aha.  Thanks for the help.  I had indeed read the docs, but I expected the
Makefile to be more or less a shortcut for what was listed there.  For the
record, I got it working by running this command:

apxs -o
mod_jk.so -DFREEBSD -I$JAVA_HOME/include/freebsd -I$JAVA_HOME/include \
 -I../jk -c *.c ../jk/*.c

The problem seemed to be that the Makefile was using gcc, rather than apxs,
to compile the .c files.  I'm not sure what Makefile.freebsd is doing in the
apache1.3 directory; does it have some other purpose?  Perhaps it should be
replaced with a link to the mod_jk howto, or modified to run the above
command?

Thanks again,
Tim
