[zeromq-dev] compiling zeromq on ios

[Paolo Denti]

Hi all,
i am trying to compile zeromq for ios5 and i had to change a little bit the instructions found on the wiki at page http://www.zeromq.org/build:iphone

SDK_ROOT="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer"
export CXX="${SDK_ROOT}/usr/bin/g++"
export CC="${SDK_ROOT}/usr/bin/gcc"
./configure --disable-dependency-tracking --enable-static --disable-shared --host=arm-apple-darwin10 --with-poller=kqueue --prefix=${BUILD_DIR}

changing the xcode location and adding --with-poller=kqueue because a polling system was not found (and kqueue is included in ios)

However while configuring i get the following warnings (autoconf version is 2.61)

checking errno.h usability... no
checking errno.h presence... yes
configure: WARNING: errno.h: present but cannot be compiled
configure: WARNING: errno.h:     check for missing prerequisite headers?
