Hello, I am upgrading my project to the latest trunk and I am having trouble building pjsua2-test for iOS. It also looks like libmilenage is no longer being built. I am not using pjsua2-lib or pjsua-test right now but I did not see an easy way to skip building them so I need to figure out how to get past this step. The first problem I found was that CXX is not set correctly in configure-iphone. It is set to clang instead of clang++. I added the line to change clang to clang++ in the block below to fix that problem. # Set CXX if not set if test "${CXX}" = ""; then export CXX=`echo ${CC} | sed 's/clang/clang++/'` export CXX=`echo ${CC} | sed 's/gcc/g++/'` echo "$F: CXX is not specified, using ${CXX}" fi The next problem is that the standard c++ library is not being set correctly when linking pjsua2-test. I tried passing -stdlib=libc++ or -stdlib=libstdc++ but pjsua2-test would still not link. It is not finding std::string, etc. The first part of the error is below.
