Not sure if I post the message before. I am going to compile pjsip with SILK codec on OSX for my iOS project, the steps are: - Download the latest version of pjsip and SILK 1.0.9 - Extract them into two different folders - Add config_site.h according to pjsip wiki: http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone -./configure-iphone --with-silk?../SILK_SDK_SRC_ v1.0.9/SILK_SDK_SRC_FLP_v1.0.9/ <http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone> - make dep && make clean && make I got the following errors during the compiling: Undefined symbols for architecture armv7: "_SKP_Silk_SDK_Decode", referenced from: _silk_codec_recover in libpjmedia-codec-arm-apple-darwin9.a(silk.o) _silk_codec_decode in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_Encode", referenced from: _silk_codec_encode in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_Get_Decoder_Size", referenced from: _silk_codec_open in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_Get_Encoder_Size", referenced from: _silk_codec_open in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_InitDecoder", referenced from: _silk_codec_open in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_InitEncoder", referenced from: _silk_codec_open in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_get_TOC", referenced from: _silk_codec_parse in libpjmedia-codec-arm-apple-darwin9.a(silk.o) _silk_codec_decode in libpjmedia-codec-arm-apple-darwin9.a(silk.o) "_SKP_Silk_SDK_get_version", referenced from: _pjmedia_codec_silk_init in libpjmedia-codec-arm-apple-darwin9.a(silk.o) ld: symbol(s) not found for architecture armv7 collect2: ld returned 1 exit status make[2]: *** [../bin/pjsua-arm-apple-darwin9] Error 1 make[1]: *** [pjsua] Error 2 make: *** [all] Error 1 Any suggestions will be appreciated. -------------- next part -------------- An HTML attachment was scrubbed...
