iOS library to BitCode

Question

I recently downloaded Xcode 7 beta, and Xcode complains about some of my C libraries not being compiled into BitCode. How would I go about telling Clang to produce BitCode t

Answer 1

What you need is -fembed-bitcode. When ENABLE_BITCODE is enabled, Xcode builds with -fembed-bitcode-marker for regular builds and with -fembed-bitcode for archive builds. One option simply "marks" where the bitcode would be in the binary after an archive build and enforces the new bitcode rules, while the other actually does the full-on bitcode generation, which is likely slower and thus not enabled on every kind of build.
