...hain): Undefined symbols for architecture armv7: "_add_gas", referenced from: _main in main_ios_clang.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) I find after add '_' to add_gas label in iosasm_clang.s(change all add_gas to _add_gas) will get rid of this error, but this will raise error(can't find symbol 'add_gas' when linking) in gcc tool chain. I don't know whether it's llvm's feature or not. Thanks for any help! =============file: main.c=============================...
