Hi, I'm using 10.7.1 and the latest version of XCode (4.1 I believe) Doing a stock standard pull down of the latest publicly available version pjsip 1.10 from the site, compiling for iPhone. Make the changes to my config_site.h to specify iPhone and include the default but I'm getting stuck at the following point: if test ! -d ../bin; then mkdir -p ../bin; fi /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 -o ../bin/pjlib-util-test-arm-apple-darwin9 \ output/pjlib-util-test-arm-apple-darwin9/main.o output/pjlib-util-test-arm-apple-darwin9/xml.o output/pjlib-util-test-arm-apple-darwin9/encryption.o output/pjlib-util-test-arm-apple-darwin9/stun.o output/pjlib-util-test-arm-apple-darwin9/resolver_test.o output/pjlib-util-test-arm-apple-darwin9/test.o output/pjlib-util-test-arm-apple-darwin9/http_client.o ../lib/libpjlib-util-arm-apple-darwin9.a /Users/dan/Documents/Development/ios/Internal/pjsip_latest/pjlib/lib/libpj-arm-apple-darwin9.a -O2 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk -framework AudioToolbox -framework Foundation -luuid -lpthread -framework CoreAudio -framework CoreFoundation -framework AudioToolbox -framework CFNetwork -framework UIKit ld: library not found for -luuid I think it may be a Lion error but I'm not 100% sure. I'm just doing a bog standard configure-iphone, make and make dep. I've tried running with the --disable-ssl flag on but it still will not compile properly and will stop at this -luuid flag. I think there may not be a check for whether the supplied version of -luuid is working based on the version of Xcode or the OS you have installed. Any advice? -- Dan Nolan
