Re: dl(): Invalid library (maybe not a PHP library)

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.
