[fpc-devel] fpc fails to link against libc on some architectures due to multiarch
reassign 636802 fpc thanks From my testing on armel I now belive that the issue causing the lazarus build failures is a problem with freepascal and multiarch. I haven't tried to troubleshoot the issue on powerpc or sparc as I don't have access to them but I presume it is the same issue. On armel the problem seems to be that freepascal can't find crti.o in the new multiarch path. Confusingly if freepascal can't find crti.o then rather than throwing an error it simply omits it from link.res. Manually pointing freepascal at the multiarch path by using -Fl/usr/lib/arm-linux-gnueabi (for armel) allows the test program to be built successfully. I presume the problem is the same on powerpc and sparc but I have no way of testing those. So it would seem that the multiarch library path for the relavent architecture needs to be added to the default freepascal search path either through adding it to the default configuration file or adding it to the hardcoded list in fpcsrc/compiler/systems/t_linux.pas . ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

And more important for me: the same code I can use on several OS: Android, WebOs, Linux, Windows, .. iOs ( I hope that FPC will be able to crosscompile to iOs soon), server can be embedded or standalone This might not be possible from non Apple targets, because of Apple's licence restrictions (the OS X users might be able to tell more regarding this). If you have a OS X and the iPhone SDK this is already possible... I count on it.

Right now I have a testing hardware with a processor that does not do hardware rendering and the GUI (I just tested some standard "Desktop"s) seem rather sluggish. In the end I supposedly will use a chip that has a hardware rendering unit, thus using fpGUI with openGL support seem a perfect choice.

The Freepascal examples run a bit strange (maybe ARM EABIv7 for Cortex 8, still palyimng with it) We4 trust that you will get it going :). You definitely only need JNI before Android 2.3.

Besides, it is a simple XML configuration file for the keyboard mapping and if you want to use it: JNI is inconvienient but NOT difficult. There is C++ code for IME softkeybord bindings available from the android developer website. From the platform highlights 2.3: "*Native input and sensor events* Applications that use native code can now receive and process input and sensor events directly in their native code, which dramatically improves efficiency and responsiveness. Native libraries exposed by the platform let applications handle the same types of input events as those available through the framework. Applications can receive events from all supported sensor types and can enable/disable specific sensors and manage event delivery rate and queueing." 2> Action completion. In standard apps you can for example click on a video and complete the action with any installed video player, and this requires access to the SDK which is only available from the Java side or from the bindings which I built See the 2.3 platform highlights above. 3> Application lifecycle, also something different from other platforms What do you mean? It isn't.( persé). If your APK is packaged and signed correctly, an Android machine that isn't supported won't see your app in the market. If that is what you mean.

Also lower than 2.3 issue, but you have to provide for it in code or use a browser approach, that's true. I must say I am still playing and can't say I have things working in a generic way.
