Ffmpeg will not build in my project, works fine in the sample application

Question

I tried for several hours, but I cannot figure it out. I use KXMOVIE in my project. I downloaded and compiled ffmpeg binaries according to the instructions. The sample application actually works very well, but I cannot build it in my own project. All .a files are, as shown in the sample application. I get this error when I try to build a simulator.

Undefined symbols for architecture i386: "_iconv", referenced from: _avcodec_decode_subtitle2 in libavcodec.a(utils.o) "_iconv_close", referenced from: _avcodec_open2 in libavcodec.a(utils.o) _avcodec_decode_subtitle2 in libavcodec.a(utils.o) "_iconv_open", referenced from: _avcodec_open2 in libavcodec.a(utils.o) _avcodec_decode_subtitle2 in libavcodec.a(utils.o) ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) 

What am I doing wrong? I don’t even know where to start.

Answer 1

You need to also link to libiconv. Assuming you have this, pass -liconv as a link option.

Answer 2

Directly in the development of "TARGETS" → "BuildSettings" → "Other linker flags" click "+" to add the "- liconv" element, if you have any questions, welcome to leave a message
