Hi, I have created some functions and I need to create a library for a client. I don't want him to have my source. So how can I create such thing ? Thanks, Oprah,
"...a header so that the linker can find them..." Sorry for the confusion. I do not mean a header in the sense of a C language .h file. I mean a header in the sense of structured information available at the beginning of a file (or packet, or whatever) which describes the following information. A library file often has a really simple structure that looks something like: header: (obj file1, offset) (obj file2, offset) (obj file3, offset) body: file1 file2 file3 This is an archive file that simply contains other files along with an index of where to find them, kind of like a .ZIP file without compression. You can add lots of extra features and refinements, of course. As far as I know, the Keil implementation includes all of the contents of an obj file if any item is referenced. The linker will omit totally unneeded .objs, which at least is a step up from handing uVision a list of .obj files, which will all be included in the project even if not needed.
