what exactly are /path/to/blah looking for? .h? .so? .a? what?!

> I'm having difficulties with that line: > > ./configure --with-openlink=/path/to/openlink/ > --with-iodbc=/path/to/iodbc/ so I've tried every combination I can think of related to "iodbc" and "openlink", and none of these are compiling. Every one results in "No such file or directory"! ./configure --with-mysql=/usr/local \ --with-apache=../apache \ #--with-iodbc=/usr/local/openlink/lib \ #--with-iodbc=/usr/local/bin \ #--with-iodbc=/usr/local \ #--with-iodbc=/usr/local/include \ #--with-iodbc=../libiodbc \ #--with-openlink=/usr/local/openlink \ #--with-openlink=/usr/local/openlink/lib Can someone tell me what exactly is /path/to/openlink and /path/to/iodbc? is it the .h file? is it the .so files? is it the .a files? what the heck is it? And why don't the INSTALL directions just tell me that? so if PHP expects to find the .h file, why don't they document it like: "--with-iodbc=/path/to/iodbc .h files" so people aren't confused like me. Please help. Thanks. D.
