Hi all, I had a change to see the link http://stackoverflow.com/questions/12643898/incorporating-gdal-ogr-into-an-ios-project-a-quick-guide
This was guiding to build with Xcode 4.0, the above link says that it doesn't work with Xcode version above 4.0 I just wanted to build GDAL as static library for iPhone and use the OGR library there in iPhone. I modified the build script as shown here, build_gdal_ios_cus.sh #!/bin/bash if [ "$#" -eq 0 ] then echo "No parameters supplied" else default_prefix="${HOME}/Documents/iOS_GDAL" prefix="${default_prefix}" if [ "$1" == "arm" ] then arch="armv7" fi if [ "$1" == "sim" ] then arch="i386" fi if [ "$2" == "iPhone" ] then export PATH=$PATH:/Users/w1/ctools echo $PATH #extra_cflags="-m${thumb_opt:-no-thumb} -mthumb-interwork" platform="iPhone" platform_dir="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain" platform_bin_dir="${platform_dir}/usr/bin" platform_sdk_dir="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/" prefix="${prefix}/${arch}/${platform}.platform/iPhoneOS.sdk" echo library will be exported to $prefix #export CC="${platform_bin_dir}/clang" export INCDIR="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include" export INCDIR1="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/c++/4.2.1/tr1" export INCDIRCPP="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/c++/4.2.1" #export CFLAGS="-std=gnu99 -nostdinc -I${INCDIR} -I${INCDIRCPP} -I${INCDIR1} -arch ${arch} -pipe -Os -gdwarf-2 -isysroot ${platform_sdk_dir}" export CFLAGS="-std=gnu99 -nostdinc -I${INCDIR} -I${INCDIR1} -arch ${arch} -pipe -Os -gdwarf-2 -isysroot ${platform_sdk_dir}" export LDFLAGS="-arch ${arch} -isysroot ${platform_sdk_dir}" export CXXFLAGS="-stdlib=libstdc++ -nostdinc++ -I${INCDIR} -I${INCDIRCPP} -arch ${arch} -pipe -Os -gdwarf-2 -isysroot ${platform_sdk_dir}" fi if [ "$1" == "sim" ] then platform="iPhoneSimulator" fi ./configure \ --prefix="${prefix}" \ --host="${arch}-apple-darwin" \ --disable-shared \ --enable-static \ --with-unix-stdio-64=no fi I created symbolic links to armv7-apple-darwin-gcc -> /usr/bin/llvm-gcc armv7-apple-darwin-g++ -> /usr/bin/llvm-g++ Actually points llvm-g++ -> clang++ llvm-gcc -> clang Above script was invoked as ./build_gdal_ios_cus.sh arm iPhone Configure succeeded. when I run make I get error like this (cd alg;

Can we build GDAL for iPhone with arm7 targert ?? 2. Did I have missed or misconfigured something ??? Any suggestion or references on web will be of great help. Thanks Gane
