Subject Re: Problems with Tomcat/Jserv on Solaris
Date Fri, 06 Oct 2000 22:32:03 GMT
Hi Ed,

I had problems building mod_jserv.so on Solaris 2.7 last week (I got
a different error number but the 'apxs -c *.c -o mod_jserv.so' failed.
I found something that worked and I'm using tomcat 3.1 w/ apache 1.3.12
as we speak.  So maybe try this:
	recompile apache and use the 'configure' script in the apache
	toplevel directory

	run:  ./configure [prefix=<an_install_dir_other_than_default>] \
		  --enable-module=so --enable-rule=SHARED_CORE \
		  --enable-module=most --enable-shared=max
		(NOTE: I'm not sure that last 2 options are necessary,
	        but the others are).
	(then do 'make' and 'make install')

Now recompile tomcat's mod_jserv.so like this:
	apxs -c *.c -o mod_jserv.so
	ld -G autochange.so mod_jserv.o jserv_wrapper_win.o \
		jserv_wrapper_unix.o jserv_wrapper.o jserv_watchdog.o \
		jserv_utils.o jserv_status.o jserv_protocols.o \
		jserv_mmap.o jserv_image.o jserv_balance.o \
		jserv_ajpv12.o jserv_ajpv11.o autochange.o mod_jserv.so

(Then run 'httpd -l' to be sure that mod_so.c is compiled in.  I
copied both autochange.so and mod_jserv.so to apache's libexec dirs.)

I'm a newbie so maybe some of these steps aren't required, but I did
get things working.  

I got this idea from a great source of help:
	http://www.ccl.net/cca/software/UNIX/apache/tj3.1/README.html.
I wish the tomcat folks would put a link to this from the tomcat
website!!
