I found one problem. I had to add "=shared" after --enable-my_ext. So, this is what I did:
./configure --enable-my_ext=shared
Now, the makefile looks much better. (I have attached the Makefile.) However, I get errors in make. Those errors are generated when invoking the libtool command.

* Thus wrote Anas Mughal ([EMAIL PROTECTED]):
I have followed the instructions in the PHP documentation on how to build a custom dynamic extension. After running ext_skel, I did NOT add any custom methods. I built the extension using the followind commands:
Compiling cc -fpic -DCOMPILE_DL=1 -I/usr/local/include -I. -I.. -I../Zend -c -o <your_object_file> <your_c_file>
Linking cc -shared -L/usr/local/lib -rdynamic -o <your_module_file> <your_object_file(s)>
1. edit the config.m4 and remove the dnl's on the lines that look somethign like: dnl PHP_ARG_ENABLE(baz, whether to enable baz support, dnl Make sure that the comment is aligned: dnl [ --enable-baz Enable baz support])
2. ./phpize
Creates the configure environment
3. ./configure --enable-baz 4. make 5. make install
the make install just copies the file in the modules/ dir to your php module directory.
HTH,
Curt
