Compiling libpq with iOS SDK 4.2

I am trying to compile libpq for arm and i386 again with iOS SDK 4.2.

I did last year for SDK3.x with no problems.

Now, when I want to create a bold binary with two files, I get this error:

specifed architecture type (arm) for file (/Users/montx/mylibs_sdk42/libpq.arm) does not match its cputype (7) and cpusubtype (3) (should be cputype (12) and cpusubtype (0))

I am going again because my compiled files do not work with the latest iOS4.2

 Detected an attempt to call a symbol in system libraries that is not present on the iPhone: fcntl$UNIX2003 called from function pg_set_noblock in image GlobalScan. If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first.

thanks!

Here is the full script:

 #!/bin/bash DEVROOT=/Developer/Platforms/iPhoneOS.platform/Developer SDKROOT=$DEVROOT/SDKs/iPhoneOS4.2.sdk rm -rf /Users/montx/mylibs_sdk42 mkdir /Users/montx/mylibs_sdk42 #Store there compiled libs make clean #Build ARM library ./configure --host=arm-apple-darwin --without-readline --disable-ipv6 CC=$DEVROOT/usr/bin/arm-apple-darwin9-gcc-4.0.1 CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin9/4.0.1/include/ -I$SDKROOT/usr/include/" CFLAGS="$CPPFLAGS -arch armv6 -pipe -no-cpp-precomp -isysroot $SDKROOT" CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" LD=$DEVROOT/usr/bin/ld make -C src/interfaces/libpq cp /Users/montx/Downloads/postgresql-8.4.1/src/interfaces/libpq/libpq.a /Users/montx/mylibs_sdk42/libpq.arm #Build ARM library ./configure --host=arm-apple-darwin --without-readline --disable-ipv6 CC=$DEVROOT/usr/bin/arm-apple-darwin9-gcc-4.0.1 CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin9/4.0.1/include/ -I$SDKROOT/usr/include/" CFLAGS="$CPPFLAGS -arch armv6 -pipe -no-cpp-precomp -isysroot $SDKROOT" CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" LD=$DEVROOT/usr/bin/ld #Then build i386 library ==> the simulator is 32bits CFLAGS="$(OTHER_CFLAGS) -mmacosx-version-min=10.5" LDFLAGS="$(OTHER_LDFLAGS) -mmacosx-version-min=10.5" make clean && ./configure CFLAGS="-arch i386 -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5" && make -C src/interfaces/libpq cp src/interfaces/libpq/libpq.a /Users/montx/mylibs_sdk42/libpq.i386 #Then make fat binary $DEVROOT/usr/bin/lipo -arch armv6 /Users/montx/mylibs_sdk42/libpq.arm -arch i386 /Users/montx/mylibs_sdk42/libpq.i386 -create -output /Users/montx/mylibs_sdk42/libpq

This works for me for the hand library, but I am using gcc 4.2 and I am targeting armv7

 DEVROOT=/Developer/Platforms/iPhoneOS.platform/Developer SDKROOT=$DEVROOT/SDKs/iPhoneOS4.2.sdk ./configure --host=arm-apple-darwin --without-readline --disable-ipv6 \ CC="$DEVROOT/usr/bin/gcc" \ CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ \ -I$SDKROOT/usr/include/" \ CFLAGS="$CPPFLAGS -arch armv7 -pipe -no-cpp-precomp -isysroot $SDKROOT" \ CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \ LD=$DEVROOT/usr/bin/ld make -C src/interfaces/libpq cp src/interfaces/libpq/libpq.a lib/libpq.arm

My old simulator script no longer works, and it works fine again iOS 3.2.

 DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer SDKROOT=$DEVROOT/SDKs/iPhoneSimulator4.2.sdk $ROOT_DIR/configure --host=i386-apple-darwin \ CC="$DEVROOT/usr/bin/gcc" \ CPPFLAGS="-I$SDKROOT/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ \ -I$SDKROOT/usr/include/ -mmacosx-version-min=10.5" \ CFLAGS="$CPPFLAGS -arch i386 -pipe -no-cpp-precomp -isysroot $SDKROOT \ -mmacosx-version-min=10.5" \ CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \ LD=$DEVROOT/usr/bin/ld make -C $ROOT_DIR/src/interfaces/libpq

Update

Here is the full script. Highlight the bash script in the postgres directory and build. Your project includes $ POSTGRESDIR / src / include and $ POSTGRESDIR / src / interfaces / libpq to get the necessary headers. Note that this works for Postgres 8. Did not test it on Postgres 9.

 #!/bin/bash set -e if [ -d "./lib" ] then echo "Existing libs deleted" rm -rf lib/* else echo "Generating output directory" mkdir lib fi if [ -e "./src/Makefile.global" ] then make -C ./src/interfaces/libpq distclean fi chmod u+x ./configure #Build i386 library DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer SDKROOT=$DEVROOT/SDKs/iPhoneSimulator4.2.sdk ./configure --host=i386-apple-darwin --without-readline --disable-ipv6 \ CC="$DEVROOT/usr/bin/gcc-4.2" \ CPPFLAGS="-I$SDKROOT/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ -I$SDKROOT/usr/include/ -mmacosx-version-min=10.5" \ CFLAGS="$CPPFLAGS -arch i386 -pipe -no-cpp-precomp -isysroot $SDKROOT -mmacosx-version-min=10.5" \ CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \ LD=$DEVROOT/usr/bin/ld make -C ./src/interfaces/libpq cp ./src/interfaces/libpq/libpq.a lib/libpq.i386 #Build ARM library make -C ./src/interfaces/libpq distclean DEVROOT=/Developer/Platforms/iPhoneOS.platform/Developer SDKROOT=$DEVROOT/SDKs/iPhoneOS4.2.sdk ./configure --host=arm-apple-darwin --without-readline --disable-ipv6 \ CC="$DEVROOT/usr/bin/gcc-4.2" \ CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ -I$SDKROOT/usr/include/" \ CFLAGS="$CPPFLAGS -arch armv7 -pipe -no-cpp-precomp -isysroot $SDKROOT" \ CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \ LD=$DEVROOT/usr/bin/ld make -C ./src/interfaces/libpq cp ./src/interfaces/libpq/libpq.a lib/libpq.arm

Github has a libpq-ios project. I used it.
