Re: GNUmakefile

[Justin Lolofie]

Ok, so I built PLDatabase as a single library and it seemed to work fine. But when I try to use it in my tool I get the error below. When its reading PLDatabase headers it seems to not know about NSObject. I must be doing something out of order- anyone have any idea?

One other question- PLDatabase is an sqlite wrapper- it occurs to me that neither makefile (library or tool) tells the linker about sqlite- should I have done this in the library makefile or the tool makefile?

First, Justin needs to compile pldatabase. This raises the question if
he should build it as a library or a framework. In any event, the
natural approach is to write a GNUmakefile to replace the Xcode
project file that comes with pldatabase (or use some tool to convert
it?). If someone tackles this properly, it would be nice to get the
makefile accepted upstream.
