I'm running Debian Sid, using SDCC 3.5.0 for the gbz80 architecture. In my statically-linked library, I have been using only one source file, but today I had a reason to add another. In this second source file, I defined gb_memcpy which is a version of standard memcpy that uses an 8-bit length parameter instead of a size_t.
I changed calls of memcpy in my library to gb_memcpy, and the library itself compiles without error (using "sdcc -c" and packing the resulting .rel files into an archive, as stated in the documentation). However, when I try to compile my test program (in which I also tried to use gb_memcpy), I got an undefined reference error claiming I had not defined gb_memcpy for both the test module and the module in my library which used it. I triple-checked the .rel file to make sure it was indeed defined, and I checked the archive to make sure that the .rel which defined the _gb_memcpy symbol was included. The error text shows: ?ASlink-Warning-Undefined Global '_gb_memcpy' referenced by module 'gbtest' ?ASlink-Warning-Undefined Global '_gb_memcpy' referenced by module 'gbscreen' If there's any other information you need, I can provide it. Code itself doesn't seem to be relevant here. I'm including the right header files (thus the compiler doesn't error), and I've passed the proper -L flag to include the library when compiling. I've made no changes from the last working build of my library other than adding this file/function. My guess is it's something to do with the existence of the separate file and not the function itself. Happy Hacking, David E.
