site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Organization: University of California San Francisco--Biostatistics Can anyone summarize, or direct me to a summary, of the requirements for mixing and matching different library and object formats? In particular, I have an R package (a module for a statistics system) that includes C code in the LAM library. LAM was present only as .a and .la files, not .dylib. The R module included a .so file, which I think is a "bundle". The LAM code seems to be inside the .so file (otool shows no external links to lam, and does show symbols and code inside the .so file). And it all seemed to work. I am used to dynamically loaded code requiring special options at compile and link time, and would expect static (.a) libraries not to work in this scenario. The docs I've seen mention no such restriction for Darwin, though I've seen some references to PIC (compile time) helping performance. One non-apple site said the common option was necessary. Basically, I'm wondering what combinations of compile and link formats are possible, and which are recommended. Thanks. -- Ross Boylan wk: (415) 514-8146 185 Berry St #5700 ross@biostat.ucsf.edu Dept of Epidemiology and Biostatistics fax: (415) 514-8150 University of California, San Francisco San Francisco, CA 94107-1739 hm: (415) 550-1062 _______________________________________________ Do not post admin requests to the list.
