Ok, I have a first working version. It's in head and will be in tomorrows snapshot as well. So here is some information on how to use it: The module to access debug information generated by ld65 is part of the cc65 source distribution in the src/dbginfo directory. It is expected to be compiled with and linked against a C source (it is no dynamic library). I've tried to make it self contained, so it is just one .c and one .h module. Compiler requirements: The code uses vsnprintf, so it needs a compiler that complies at least partially with C99. Interface: I've tried to make the interface as simple as possible, but since quite some information is passed back, some structs are necessary. Completeness: There is currently only support for line information, so it is possible to add source code support to a debugger/emulator. Access to symbols will be added shortly, but that is not as useful as it could be, since support for scopes is missing (they're not written to the object files and therefore not available to the linker). So there are quite some automatically generated symbols with the same name that cannot be distinguished. There is also an example/test program that shows how to use the module. I would still call parts of the code experimental. For example the way how errors are passed back may be changed. Another problem may be that the code checks the return of malloc() using assert() - so a program using the module will terminate immediately if it runs out of memory. If you use this code, please be prepared to make some adjustments later since the API may still change. Feedback or suggestions are gladly appreciated!
