Hello Everyone,

I will preface this post by saying I am far from an Apache guru. I have however used Apache for some time as a reverse proxy to our MSExchange environment. Unfortunately Apache does not offer support for Outlook anywhere. Someone however developed a module for Apache 2.4 recently that fixes this limitation allowing Apache to act as a reverse proxy for Outlook anywhere. Unfortunately there is virtually no documentation on how to properly install the module and that is where I need help.

The module is located here:

I am running Apache 2.4.4 on CentOS 6 64bit and performed the following steps to install the module, all of which appear to have completed successfully:

apxs -c mod_proxy_msrpc.c msrpc_pdu_parser.c msrpc_sync.c

apxs -i -a mod_proxy_msrpc.la

When attempting to start apache I get the following error:

Cannot load /usr/lib64/httpd/modules/mod_proxy_msrpc.so into server: /usr/lib64/httpd/modules/mod_proxy_msrpc.so: undefined symbol: uuid_unparse

I have all uuid and uuid-devel packages installed. Beyond that I am not sure what the problem could be. Any help would be greatly appreciated. I hope I am overlooking something simple that is not unique to this module as the author does not reply to posts.

Thanks in advance.

In the source there is #include <uuid/uuid.h>.

is in your uuid.h the function uuid_unparse() defined?

You may ask the author of that module which lib uuid version he uses.

I found the solution. I was not using the correct flag when compiling. In case anyone else uses this module in the future it should be done as follows:

apxs -c -Wl,-luuid mod_proxy_msrpc.c msrpc_pdu_parser.c msrpc_sync.c

followed by

apxs -i -a mod_proxy_msrpc.la

Make sure you have libuuid and libuuid-devel installed.

Thanks for the help!

Does not look like it. The requirement for sys/inotify.h in msrpc_sync.c removes any easy portability prospects.
