Re: Problem cross compiling for iPhone (iOS 4)

Hi All,

Got a version of the (simple) script I used to build the libraries:

#!/bin/sh

# First we unset some shell variables and set some important (??) onces
unset CC
unset CFLAGS
unset LDFLAGS
unset CPP
unset PLATFORM

export buildPath=`pwd`

# make arm target
export CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1
export CFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
export LDFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -Wl,-syslibroot \ /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk"
export CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp

cd $buildPath/freetds-0.83.dev.20110125_arm
./configure --disable-shared --disable-odbc --disable-pool --disable-server --disable-apps --host=arm-apple-darwin10 --prefix=$buildPath/build/arm 
make -j4
make install

# make i686 (Simulator) target
unset CC
unset CFLAGS
unset LDFLAGS
unset CPP

export CC=/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/i686-apple-darwin10-gcc-4.2.1
export CFLAGS="-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk"
export LDFLAGS="-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk -Wl,-syslibroot \
Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk"
export CPP=/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/cpp

cd $buildPath/freetds-0.83.dev.20110125_i686_SIM
./configure --disable-shared --disable-odbc --disable-pool --disable-server --disable-apps --host=i686-apple-darwin10 --prefix=$buildPath/build/i686
make -j4
make install

# make the universal libraries
for lib in libct.a libsybdb.a; do lipo -create -output $buildPath/build/universal/$lib $buildPath/build/arm/lib/$lib $buildPath/build/i686/lib/$lib; done

The script creates the correct archs in their respective folders and lipo creates a (correct) universal library. 
I do get the same 'error' when I try to link to the i386 library (not the universal one).

It must be something I do wrong, but what... (tearing my hair out....)

Regards,

Xander
