[fpc-devel] Building the Android branch

[Sven Barth]

Hello together!

I'm currently testing the Android branch and I've already reached a 
problem when trying to build it. I've downloaded the current Android NDK 
r8c and then tried to run the following command line:

make all OS_TARGET=android CPU_TARGET=arm 
CROSSBINDIR=/mnt/data/downloads/dev/android/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin 
BINUTILSPREFIX=arm-linux-androideabi- OPT=-dFPC_ARMEL CROSSOPT="-CpARMv6 
-Cfsoft"

This works until the process reaches the CHM package where it wants to 
compile chmls. The compiler then returns with a linker error when 
executing the following command (reported by fpmake):

/mnt/data/source/fpc/fpc-android/compiler/ppcrossarm -Tandroid 
-FEchm/bin/arm-android -FUchm/units/arm-android 
-Fu/mnt/data/source/fpc/fpc-android/rtl/units/arm-android 
-Fu/mnt/data/source/fpc/fpc-android/packages/fcl-xml/units/arm-android 
-Fu/mnt/data/source/fpc/fpc-android/packages/fcl-base/units/arm-android 
-Tandroid -Parm -XParm-linux-androideabi- -Xr -Ur -Xs -O2 -n 
-Fu/mnt/data/source/fpc/fpc-android/rtl/units/arm-android 
-FD/mnt/data/downloads/dev/android/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin 
-dFPC_ARMEL -darm -dRELEASE -CpARMv6 -Cfsoft -viq chm/src/chmls.lpr

When I run that command manually from within the packages directory I 
get the following output:

Am I doing something wrong here or is the compiler the culprit?
