Differences between version #8184 and #8185
20a21 > ===== Static Linking ===== 21a23 > When generating a static library (as required by iPhone), instead of a dynamic ndll, some care must be taken to ensure the "DEFINE_PRIM" macro works correctly. Most linkers today will only pull symbols from a static library if then exist in an obj file (ie, c++ file) that has other symbols explicitly required be the application. Since the CFFI functions are located by name, the linker does not explicitly know they are required, so the exporting DEFINE_PRIM macros will not be linked, and will not export their functions. To fix this, ensure that there is at least 1 real symbols in each c++ file that is referred to externally. This can simply be a dummy function, or an "extern int". Putting all the CFFI "glue" functions in a single file is not such a bad idea, and reduces this problem to a single symbol. 22a25,28 > ===== Array Access ===== > > One of the main differences between neko CFFI and C++ CFFI is how arrays are treated. >
