Does it have process-shared mutexes and events?

This symbols should be weak and therefore should not cause dup errors. > For iOS 8.1 (arm v7) the error is: > The build currently stops on linking libfbclient.dylib: > Undefined symbols for architecture armv7: > "_libiconv", referenced from: > (anonymous namespace)::IConv::convert(Firebird::AbstractString&, > void*) in libcommon.a(isc_file.o) > "_libiconv_open", referenced from: > (anonymous namespace)::IConv::openIconv(char const*, char > const*) in libcommon.a(isc_file.o) > "_libiconv_close", referenced from: > (anonymous namespace)::IConv::closeIconv(void*) in > libcommon.a(isc_file.o) > ld: symbol(s) not found for architecture armv7 > clang: error: linker command failed with exit code 1 (use -v to see > invocation) > That's even more funny. There _is_ .h file that redefined iconv* as libiconv*, but there is no such entries in available libraries. Looks like additional library should be added to the link. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
