How would I install a PECL extension on windows? Say I want the PECL oAuth extension on Win
The PECL installer downloads the source code of the extension and tries to compile it with your local C compiler. The problem is that the whole process is designed for Unix systems, where a C compiler is available or can be easily installed. Setting an environment to compile C code under Windows is pretty complicate.
The ideal solution is getting a DLL file that someone already compiled. That's what the pcle4win site was for. However, there's currently no official repository to download PECL DLLs so you only have two alternatives:
It'd be cool that there was a DLL repository out there but I'm unaware of any.
