Hi,
I'm using 6502bench SourceGen to disassemble a program that was compiled with an unknown APW C version.
I'm relying on CiderPress disassembler capability to look into APW's CLIB because, being a library, it has no relocation information and most disassemblers that I've tried won't deal with it. (do you have any suggestions on that topic?)
Well, I'm trying to match CLIB function signatures inside my program, and I need to find out the exact version of the CLIB that was used to build it. I've had a partial success with the CLIB from APW C 1.0B7.
Now I'm searching for APW C version 1.0B4, and possibly earlier versions like 1.0B1 that was released, too.
Also, any other beta versions that you might offer would be highly appreciated.
Thank you

To disassemble a IIgs load file (S16, EXE, PIF, etc), one needs to replicate the system loader behavior. To disassemble a IIgs OBJ or LIB file, one also needs to replicate linker behavior. The SourceGen OMF converter only acts like a loader.
One thing you might try is to write a simple program that references every function in the library, compile and link it into an EXE, and disassemble that. A simple table of function pointers ought to cause the linker to pull in the functions. Assuming that works, then depending on how everything gets laid out in the binary, creating it as an array of {pointer, "name"} structs might help keep things straight while poking around.

I see two possible solutions;
http://www.byteworks.us/Byte_Works/Morgue_files/CPW.img
I think this is a small-c version.
and the disk labeled ; "0298 APW - C - Workdisk, Exsamples.po" from the brutal deluxe archive.
This is the earliest C compiler i have seen for the IIGS. Pre-dates APW-C. Not sure why it's labeled as APW-C.
The release notes mention it as the MegaMax C compiler. Was used as a ADTS pre-release system inside apple before APW-C.
Byteworks APW-C is a totally different system.
Hope this helps.
