Cross-compiling ZeroMQ to ARM for use in a MonoTouch iPhone app configure settings

Question

I\'m attempting to use the ZeroMQ library in an iPhone app developed in C# using MonoTouch. I\'ve solved almost all of the problems, but have fallen at the last hurdle. I\'m usi

Just thought I'd share that I found the answer in the end - the trick was to add CPP="cpp" CXXCPP="cpp" to the ./configure statement, giving:

./configure CPP="cpp" CXXCPP="cpp" CXX=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-g++-4.2 CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2 LD=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ld CFLAGS="-O -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" CXXFLAGS="-O -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" --disable-dependency-tracking --host=arm-apple-darwin10 LDFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar AS=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/as LIBTOOL=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/libtool STRIP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/strip RANLIB=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ranlib

I used this configuration to successfully build ZeroMQ for ARM, as used in my new iPhone app I Buzzed First (available at http://itunes.apple.com/gb/app/i-buzzed-first!/id490622820?mt=8 )

That question is not really related to MonoTouch but on how to compile 0MQ on the iOS (ARM). Have a look at: Compile C lib for iPhone

Hopefully it will help you and also cover the next question: fat universal binaries using lipo. The good news is that, if this works on the simulator, then you likely already covered any MonoTouch related issue :-)
