Dear Rick, I dont think so. Will check that. Thanks!

That process will get launched when rexximage runs, so it might be hanging up because the daemon isn't getting created on startup.

I already had the chance to try the build on the emulated device. Out of the box it is not working. When trying to execute "./rexx -v" I get an error which says that "librexx.so" is not found. The problem here is that r-path is not available for Android and so its a problem to find the libraries. A workaround for now is to use "LD_LIBRARY_PATH=./lib bin/rexx -v" This works and I'm getting the version info. At least that's a good sign. The problem with this solution is, nothing else works. I tried multiple things including a small hello-world file but every time I want to execute rexx commands I wont get an output. It seems like its stuck somehow. Only <STRG>C helps. I attached a screenshot. Its not a problem with the shell itself because my small c++ sample program (sums two integers given by the user) works just fine even with the user input. The Shell running on the Android device is mksh. See https://www.commandlinux.com/man-page/man1/mksh.1.html My thoughts on that problem: First of all @Erich Steinboeck you told me it will be necessary to manually, or automatically upload rexximage together with librexx.so and librexxapi.so and the *.orx Files to the device. To finish my build I did not do that for now. Instead, I took the rexximage executable from another Linux build and let CMake generate the rexx.img from this rexximage file. I'm aware that this is probably the wrong way but it was faster to implement for now. Although I'm pretty sure that this is not the problem here. Btw. its possible to connect via command line to the device. I tried your suggestion manually. So I pushed the rexximage (generated during the build with the Android-Toolchain) together with librexx.so and librexxapi.so to the device. "./rexximage rexx.img" again, gives an error regarding librexx.so. But with the LD_LIBRARY_PATH-Command its executable but with the same result which I got from the rexx executable. It is stuck. Therefore the problem must arise earlier. My suspicion is that something is maybe wrong with the libraries. To further limit the problem down to a specific file I wanted to try out which library file gets linked in which order. It seems that "librexx.so" is first followed by librexxapi.so. When removing "librexxapi.so" and trying to build the rexx.img. I get the error message that "librexxapi.so" could not be found. Therefore I assume that "librexx.so" is fine. At least it isn't stuck till now. When I'm re-adding "librexxapi.so" the process freezes again. So I derive that the problem has to be in "librexxapi.so". It is built at around 13-15 percent. The only thing I changed here was to replace the open64() function with the open() function from fentl.h library. There is a flag for open() called O_LARGEFILE which should have the same effect as open64() but I did not use this flag. A few info's to the host and target system: Host System x86_64 Arch Linux Target System x86 Android API LVL 29 I also tried Target System x86_64 Android API LVL 30 As a side note I want to mention that I have 34 files in the /lib-Folder for a standard Linux build. There are only 24 files in the /lib-Folder for an Android build. Of course maybe I'm totally wrong with my assumptions but I"m limited to my observations here. Maybe someone has further ideas?
