[FYI, I am seeing a response on the Apache list website, but I am NOT receiving the response here in my Yahoo email :( !! So I will respond here]

Here is the 'ldd webgate.so'

FYI, per my original msg below, when I do "nm -D libclntshcore.so", I *DO* see the slts_runmode symbol, but it is labelled "B".

I will try 'strace -e openat httpd -t' after this and post after that.

Thanks,

Jim

Hi,

I am trying to get the "httpd -t" test to work but am getting an "undefined symbol" message.

The Apache is 2.4.39 version that I built from source on a CENTOS 8.5 machine.

Here's what I am running:

export LD_LIBRARY_PATH=/apps/Oracle/Middleware/Oracle_Home/lib:/..../apps/Oracle/Middleware/Oracle_Home/webgate/ohs/lib/

./httpd -t -DOHS_MPM_EVENT -f /apps/httpd2.4/conf/httpd.conf

httpd: Syntax error on line 512 of /apps/httpd2.4/conf/httpd.conf: Syntax error on line 5 of /apps/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/config/fmwconfig/components/OHS/instances/ohs1/webgate.conf: Cannot load /apps/Oracle/Middleware/Oracle_Home/webgate/ohs/lib/webgate.so into server: /apps/Oracle/Middleware/Oracle_Home/webgate/ohs/lib/webgate.so: undefined symbol: slts_runmode

I am trying to get this Apache working with an Oracle webgate module, which is configured in the Apache httpd.conf by including an include line:

include "webgate.conf"

I've been checking for that "slts_runmode" symbol, and I've found references in two .so files:

libclntsh.so

libclntshcore.so

I ran "nm -D" on those 2 .so files:

[orcladmin@localhost lib]$ nm -D libclntsh.so | grep slts_runmode
U slts_runmode

[orcladmin@localhost lib]$ nm -D libclntshcore.so | grep slts_runmode
000000000056d120 B slts_runmode

From what I was able to find the "U" means "undefined" and the "B" stands for "BSS"?

I was wondering if there is any way to configure the Apache to ignore/bypass that "undefined symbol" problem?

From what I was able to find, that "slts_runmode" is something to do with database, which I am not using at all, so I am really hoping if there is some way to either workaround the "undefined symbol" or to tell Apache to ignore the "undefined symbol", I think that would be sufficient for what I am trying to do.

Thanks,

Jim
