Do you have your older device you could try your ppcarm on? You will have to address the PIC/PIE issue but you could be looking at the compiler using machine language instructions that aren't supported by your hardware (as previously described). If my guess about the tablet being newer is correct, I doubt it. Still it looks like my ppcarm supports over a dozen different instruction sets. And their is always the chance some other form of crash is causing that message. Android 6 *definitely* requires PIC binaries, that *definitely* changed in the past three years. A three year old version of FPC would not have been compiled that way. FYI: a PIE binary won't load on a non-PIE enabled OS. I had been reading about ways Google devs were trying to work around that. Of course Google wouldn't want that to happen... so I imagine their efforts were squashed. - On 11/16/2015 Yuri Sidorov wrote: -- Subject: Re: [fpc-devel] PIE compatible output?

And you may need to fiddle with the instruction set used. You can either do this by cross compiling on another FPC supported platform, which typically means building your own "binutils". Or, depending on what you have available, the needed prebuilt binaries to cross compile may already be available through the usual FPC channels (I think I saw windoze zips). Or you can leverage a *real* Linux based ARM platform such as Rpi or CHIP. That was actually one of my motivating factors to get involved with CHIP. A native ARM platform to build binaries, specifically units, for Android for only $9 USD! I still want to cluster a bunch of these things in a stock PC tower case to use as compiling nodes.

But it doesn't provide proper terminal emulation and came packaged with FPC 2.6 pre v3 beta, which was good at the time since 3 hadn't been out yet. :-D I patched and added many FPC units to his original set, which I think he released. -- Jon Foster JF Possibilities, Inc. j...@jfpossibilities.com ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

For Java-native libraries too ?
If I understand your question correctly: No, since the library isn't
"executed" (in the traditional *nix sense) its "loaded" and used. As you
stated you need an Android Java (Dalvik) app, which gets executed, and then
it loads the library and calls the functions in it. But never forget you
need someway to display stuff... and the normal Pascal methods of providing
user interaction are not available on Android.
Take this simple program:
program hello;
uses SysUtils;
var
s: string;
begin
write('Enter your name: ');
ReadLn(s);
WriteLn('Hello ', s);
end.
Assuming you made it into a library and write a Dalvik wrapper you still
need some place for the input to come from and the output to go to. On
Linux this would be "standard in" and "standard out", attached to a
terminal somewhere/somehow (VGA adapter, xterm, pipes, ...).
Technically all you need to do this with Android is a compiler for the
architecture of the Android device (usually ARM) and a terminal app. Once
compiled you can place the app on an SD card (typically available) then
launch your terminal app, copy the app from the SD card into "/data/tmp",
"chmod a+x /data/tmp/myapp" (change "myapp" to the name of yours) and then
launch it and interact with it via the terminal app.
You have to copy the app to "/data/tmp" as that is usually the only place
on Android with a Linux file system that all users have access to. You

For no gui console application, compile your fpc java native library for the same cpu than the one of Android. For example RPi (but I am not sure it is the same cpu as android-devices). I'd like to try console apps (also with Free Vision) first in conjunction with this: http://turbocontrol.com/gnuroot.htm The only thing that console apps need is a terminal emulator. A bunch of ways that can happen and it depends on whether this is to be provided through the Android market or not. If not things are much easier. Terminal emulators abound you can pretty much just pick one. Now for the obstacles: 1. Linux (Android kernel) only runs executables from a file system that allows you to set the "execute" permission, which means that you can't just put your stuff on an SD card and run it, since FAT and descendants don't have that permission. So you have to get your exes into the internal non-FAT App storage and Android permissions throw up plenty of barriers. 2. Compiling for ARM. This can be done with cross build tools, with an ARM Linux computer or some other *nix variant available on ARM, or with several of the Android apps that provide pre-built versions of the compiler and a term environment. I actually built the compiler and tools with a CHIP / PocketCHIP (http://getchip.com/). Very inexpensive full blown Debian 8 install. But I think I had to build a bootstrap compiler with my Intel based Linux box first. Which meant building a cross "binutils" for ARM, which was fairly simple. I can probably post some scripts if desired. My final solution for compiling and running things was "Terminal IDE" Its setup for Java, C & C++ but it provides the terminal, assembler, linker, some Android packaging tools and it provides full access to the packages "home" folder which allows the executable permission. If there is an ARM bootstrap compiler, and I haven't looked in a while, you should be able to build FPC and units all from within Terminal IDE. You will want to use the automated installer for the C compiler and stuff, since that contains "binutils" (assembler, linker, ...). *NOTE* Last I looked this won't work on Android 5+, explained below (#3). My problem with it is "vi" for editing. And since other apps don't have access to its "sandbox" you have to do some juggling for a complete on device dev environment. It would technically be possible to keep source on the FAT storage (SD or internal) and just build into the sandbox, which has permissions. You will need a ".fpc.cfg" in the IDE's home folder and you won't be able to install one to "/etc". You can find the correct location by typing "echo $HOME" (case is significant) in the terminal window. I should also mention that the "hacker's keyboard" is very desirable for this. But you will probably want a larger screen size. Those buttons can get pretty small! 3. Android 5+ introduced *mandatory* address space randomization. This means that binaries compiled for <5 won't run on 5+ and visa-versa. It also means you need address independent output from FPC for 5+. I believe this is now an option in FPC 3. But I don't believe the Terminal IDE guy ever produced a build that will work on Android 5+. If distributing you will probably want to build both an address independent and non-independent version and then selectively launch the correct one. But that ties in with 4 & 5 below. 4. Google does not allow one package to require another package. So your package has to be self contained, meaning that if you need an X server or Terminal emulator it has to be combined into one package with your fpc binaries and data. This has licensing implications that may not be acceptable. Depending on your situation you may be able to take someone else's OpenSource package and hack your stuff into it. ie. Get an open source term app, "rebrand" it, inject your FPC app, and patch it to auto-start your app and shutdown when your app finishes. 5. Android *only* launches Dalvik (Java) based apps so if packaging you have to provide some kind of Java based wrapper anyways. Making #4 mandatory anyways. 6. App lifespan. Terminal apps expect that they will start and run until either their task has finished or the user signals it to stop. Android expects it can terminate and restart apps as it sees fit. This can cause problems when your app unexpectedly gets terminated. I should also mention that the JVM target for FPC seems to work quite well. So its possible to use FPC to write the mandatory Dalvik wrapper for your native FPC code. I have an App that I kept the same core code and wrote a new Dalvik front end in FPC, using the JVM target. But its very time consuming and fraught with peril. The Android UI does many unexpected things and
