recently I added preliminary arm/android support as official target for fpc. The changes are available in the
http://svn.freepascal.org/svn/fpc/branches/targetandroid/ branch. How to compile: --------------- from the command line, e.g. by issuing make zipinstall FPC=<host fpc compiler> OS_TARGET=android CPU_TARGET=arm CROSSOPT="-Cfsoft" BINUTILSPREFIX=<prefix-to-android-ndk-as-ld> you should get a nice archive with your cross compiler after completion. Before that you might need to create a new "fpcmake" tool by e.g. building a normal zipinstall to be used during building the crosscompiler (or native compiler) and put it into the path. Usage notes: ------------ - while the compiler should now be appropriately prepared for the target, the rtl likely still contains a few bugs; I successfully compiled and ran some shared libraries and created Android (sdl/OpenGL based) app generated by it. - no special packaging support at the moment, you have to do that using the ndk by replacing .so's. - no Android API header translations included in the rtl - while it is able to generate standalone executables, they have not been tested - usual disclaimer, generated code may jump in your face etc. Developer notes --------------- - the compiler does NOT define "LINUX" during compilation! It defines UNIX and ANDROID though. This will likely not change. (Background: Android is not completely Linux compatible, e.g. a few syscalls and default library functions e.g. in pthreads, ... are missing, and it generally behaves different in a few ways. This makes the amount of defines manageable by avoiding "if defined(linux) and not defined(android)". Actually, the list of things that are different is only growing) - the current interface to the OS uses syscalls, not the bionic libc. This default might change in the future at least for shared libraries, because at the moment this means that environment variables are not available (envp) for them. - shared libraries do not have argc/argv/envp available (i.e. set to 0 or nil) because of Android. - the selection of compiled packages is mostly driven by what libraries are shipped by default on Android, i.e. not much. I might have missed one or two though. - comments, questions and patches are much appreciated - I do have to warn you though that I usually do not have much time and equipment available for a lot of testing, but I am available to reviewing and committing of patches. Note that probably a lot of workarounds for the arm/linux compiler that have previously been required for getting arm/android executables to work are not needed any more. Anyway, have fun, Thomas _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
