Re: [PHP-DEV] OS X, enable embed problem, patch

This is taken care of by "auto" tools.

If you are experiencing build issues of public releases then you're doing something wrong.

I build PHP for a living in OS X and I've encountered no build issues what-so-ever related to building with dylib linking but the resulting binary will (should) still be libphp.so because apache expects this.

If you need some help I can spare a few moments and examine your build environment and offer you some pointers/advice that should help you to develop better binary builds.

Out of curiosity, why are you enabling embedded in this manner, there are very few reason that PHP needs to be built this way and the environment and dependancies need to be established for the build to be successful.

When building for embedding purposes you really want a static build (libphp.a rather than libphp.so) so I'm having a hard time understanding what exactly it is you're trying to achieve.

Please be gentle, I have very little experience developing on OS X. To be honest, the whole dylib thing seems messy and confusing to me, compared to the fairly straight-forward Linux style .so approach.
Expected behavior:
Able to configure and build on OS X with:
./configure --enable-embed

Actual behavior:
http://bugs.php.net/bug.php?id=44462

Suspected problem:
Trying to build .so instead of .dylib on OS X.

Suggested solution:
See patch below.  This makes it possible to do:
./configure --enable-embed=dylib
I did this instead of fixing --enable-embed=shared because the build process appears to be fundamentally different.
NOTE!  Once applying the patch, you need to do:
aclocal
autoconf
./configure --enable-embed=dylib
If you don't do aclocal to regenerate the necessary files, things break.
