Yes I have, and of course I will share my findings with the world for
the benefit of mankind.
I also have a follow-up question: the libprotobuf-lite.a static
library is about 500 kB which seems a little heavy. Is this normal?
I've tried to strip the symbol information but maybe that didn't
succeed.
We're using iOS SDK 4.0 with the PLBlocks compiler. The script needs
some adjustments if you are not using PLBlocks.
This produces the ARM library:
-----------------------------------------
export ARCH=arm-apple-darwin10
export ARCH_PREFIX=$ARCH-
export PLATFORM=iPhoneOS
export SDKVER="4.0"
export DEVROOT=/Developer/Platforms/${PLATFORM}.platform/Developer
export SDKROOT="$DEVROOT/SDKs/${PLATFORM}$SDKVER.sdk"
export PKG_CONFIG_PATH="$SDKROOT/usr/lib/pkgconfig:$DEVROOT/usr/lib/
pkgconfig"
export AS="$DEVROOT/usr/bin/as"
export ASCPP="$DEVROOT/usr/bin/as"
export AR="$DEVROOT/usr/bin/ar"
export RANLIB="$DEVROOT/usr/bin/ranlib"
export CPP="$DEVROOT/usr/bin/cpp"
export CXXCPP="$DEVROOT/usr/bin/cpp"

export LDFLAGS="--sysroot='$SDKROOT' -L$SDKROOT/usr/lib -L$DEVROOT/usr/

./configure --host=${ARCH} --with-protoc=protoc --enable-static --
disable-shared

And the i386 version for the simulator:
---------------------------------------
export ARCH=i686-apple-darwin10

export RANLIB="$DEVROOT/usr/bin/ranlib"
export CPP="$DEVROOT/usr/bin/cpp"
export CXXCPP="$DEVROOT/usr/bin/cpp"
#export CC="$DEVROOT/usr/bin/arm-apple-darwin10-llvm-gcc-4.2"
