I'm trying to Build PJSIP as a dynamic library for our iOS app / open-source Cocoapod. Building is done on osx 10.11.6.
I have made some progress with the help of somebody reading this mailing list (in response to http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2016-August/019448.html)
When compiling PJSIP with the "--enable-shared" option, most of the lib's are build correctly.
However, some libs are compile for the wrong architecture, in this case x86_64 instead of arm64
libg7221codec.dylib is architecture: x86_64
libgsmcodec.dylib is architecture: x86_64
libilbccodec.dylib is architecture: x86_64
libresample.dylib is architecture: x86_64
libyuv.dylib is architecture: x86_64
Whereas these are correct:
libpjsip.dylib is architecture: arm64
libpjsua.dylib is architecture: arm64
libpjsua2.dylib is architecture: arm64
+ ./configure-iphone --enable-shared
+ make dep
+ make clean
al complete correctly but
+ make
generates these warnings:
ld: warning: -undefined dynamic_lookup is deprecated on iOS
ld: warning: -flat_namespace is deprecated on iOS
and a lot of warnings looking like this:
ld: warning: ignoring file output/libilbccodec-arm64-apple-darwin_ios/iLBC_decode.o, file was built for unsupported file format ( 0xCF 0xFA 0xED 0xFE 0x0C 0x00 0x00 0x01 0x00 0x00 0x00 0x00 0x01 0x00 0x00 0x00 ) which is not the architecture being linked (x86_64): output/libilbccodec-arm64-apple-darwin_ios/iLBC_decode.o
ld: warning: ignoring file output/libg7221codec-arm64-apple-darwin_ios/common/common.o, file was built for unsupported file format ( 0xCF 0xFA 0xED 0xFE 0x0C 0x00 0x00 0x01 0x00 0x00 0x00 0x00 0x01 0x00 0x00 0x00 ) which is not the architecture being linked (x86_64): output/libg7221codec-arm64-apple-darwin_ios/common/common.o
and:
ld: warning: ignoring file /pjsip/src/third_party/lib/libg7221codec.dylib, file was built for x86_64 which is not the architecture being linked (arm64): /pjsip/src/third_party/lib/libg7221codec.dylib
What could be the reason that some lib are compiled for the correct architecture and some are not? How would I be able to fix this?
If successful, we will wrap this dynamically compiled version op PJSIP into a Cocoapod which will be maintained by us an will remain open-source.
