Specifying a different target directory for APXS

[Subra A Narayanan]

Hello folks,

I use the following command to compile my apache module:

*/usr/sbin/apxs -c mod_my.c*


this creates a *.libs/* folder and my mod_my.so file is generated in that
folder.

My question is, is it possible to specify a different target folder for my
.so file?

I have gone through the man page for apxs and wasn't able to find anything.


thanks in advance,
Subra

Hello folks,

Has anyone come across a similar situation before? Can a target folder be
specified or is that not possible?

Any help is greatly appreciated.

Joe,

Thanks for ur response.

The reason I wanted to change the target directory was because my apache
module is being compiled as one of the components of a much larger makefile.
All the other shared libraries generated by this make file, are copied in a
particular directory and hence I wanted my apache module to go in to that
directory as well. As you suggested, I could copy the .so file to whatever
directory I want later on, but I am not sure if such copying ig generally
done in a makefile.

I did try to directly use gcc to compile my apache module so that I could
specify any target directory but ran in to another issue which is detailed
here =>
http://mail-archives.apache.org/mod_mbox/httpd-modules-dev/200711.mbox/[EMAIL 
PROTECTED]

I didnt receive any helpful responses to that posting thats why I am trying
to use apxs.

Would you care to take a look at this issue =>

Thanks so much!

You DID get helpful responses - I was one of those responders who said
to use apxs.  (We pointed you to the tool because there are too many
changes across systems, platforms, etc, that it is faster, more
efficient, and better quality to use a tool that also makes the end
result more portable - go figure).

We need no more discussion on that - use apxs.  If you need a Makefile,
use the apxs tool in your Makefile.  (It IS possible, after all.)  For
example, Makefile rules might look like :

mod_test.so:
apxs -c mod_test.so
cp .libs/mod_test.so path/to/mod_test.so

install:
apxs -n mod_test -i mod_test.la

That is how I have done all of my modules.  It's easier to type "make
install" rather than "apxs -i -a -c mod_test.c".  If you think you need
help in your makefile, go to google, and type in "makefile".  Just
copying a makefile from another package seriously limits your capabilities.

Joe,

Thanks for ur reply.

Let me clarify somethingWhen I said I didnt get any helpful responses, I
meant I didn't get any answers as to what is wrong with gcc and why the
module was behaving the way it was.

Anywayspoint taken.will use apxs for compiling the module.

Hello folk,

your "problem" has nothing to do with apxs. The .libs directory is
created by libtool. You might want to contact the helpful dwellers on
the libtool mailing list.

Never needed to change that part of the build process.

That's the approach I would choose (I do for packaging my modules into
Debian packages). Why wouldn't you copy in a Makefile? Just add another
dependency:

your_very_Special_path/your_module.so: your_module.slo
cp .libs/your_module.so 
your_very_Special_path/your_module.so

I got the impression that everyone considered this a no-so-good
idea

Your -z initfirst, -fPIC and other flags may have been causing that. 
apxs is easier and faster.

Hopefully, that will work.

Don't link that stuff in.  You're compiling a module, not the
kitchen sink.  Use LoadFile if you need extra libs.

Some of those, like dl and pthread, should be accessed through APR.
Using them directly loses portability.

Why have you called your source files [name].o?
