Hi. I tried compiling AS on Jetson Tegra K1 which uses ARM processor. I used the gnuc makefile and everything compiles except as_callfunc_arm.cpp.s. It returns error about THUMB instruction not being in IT block. The whole log:

make: *** [obj/as_callfunc_arm_gcc.o] Error 1

You can also see I tried compiling with -DAS_MAX_PORTABILITY with the idea it will not use the ASM at all, but it still compiled it and threw the error. Is there some kind of flag I need to change? The ASM has defined blocks for THUMB1, THUMB2 and ARM, so techniclly I could disable THUMB and fallback to ARM?

Compiler:

For some reason I cannot post the whole g++ -v here. So I posted it here: http://pastebin.com/n4uXrVXb

The as_callfunc_arm_gnuc.S is missing a #ifndef AS_MAX_PORTABILITY condition. I'll have this added.

When compiling with max portability this code is not needed, you can simply remove as_callfunc_arm_gnuc.S from the makefile if you prefer using AS_MAX_PORTABILITY.

I'm not sure why the compilation fails though. Unfortunately my little BeagleBone Black with Angström Linux uses the soft-float ABI, and I haven't been able to make it compile with hard-float ABI yet so I'm not able to verify the assembler code for the hard-float ABI (which is where you're getting compiler errors).

Still, the same assembler instructions that the compiler is complaining about in your case are present in the soft-float ABI too, and I don't get any errors.

Do you also compile with the thumb instructions or the regular arm? My gcc has defined "--with-mode=thumb". When I added the "#ifndef AS_MAX_PORTABILITY" I got it to compile. But when I launch the project it segfaults on AS functions. It manages to create the engine, but the next function which is registering the error callback crashes (quite ironic). At first I thought it was because of asCALL_CDECL, because at that point I was running the AS_MAX_PORTABILITY flag. So I changed it into asCALL_GENERIC and same thing. I posted both of the segfaults. The callstack doesn't go any deeper than this. The whole backtrace only shows the path until it calls this function.

//With CDECL
Program received signal SIGSEGV, Segmentation fault.
0x0002e900 in as::as_engine_create ()
at NodeVision_System/scripting/angelscript_wrapper.cpp:94
94 int r = engine->SetMessageCallback(asFUNCTION(as::MessageCallback), 0, asCALL_CDECL); assert( r >= 0 ); //For errors reports

//With Generic
Program received signal SIGSEGV, Segmentation fault.
0x0002e900 in as::as_engine_create ()
at NodeVision_System/scripting/angelscript_wrapper.cpp:94
94 int r = engine->SetMessageCallback(asFUNCTION(as::MessageCallback), 0, asCALL_GENERIC); assert( r >= 0 ); //For errors reports

Then I tried removing it, just to see if it would go further. But the next function is RegisterStdString, which then calls RegisterStdStringGeneric and crashes.

It also compiled when I removed the AS_MAX_PORTABILITY and instead added the -marm flag (which is the same as --with-mode=arm). In that case everything is the same. It crashes at SetMessageCallback and when I remove it, it calls RegisterStdString, which then calls RegisterStdStringNative and crashes. Here is the full backtrace for both:

Everything works fine on Windows x86 and x64. I'm using the 2.30 version of AS.

I don't use thumb mode. Though I'll give it a try as soon as I can to see if works (probably not, since I haven't prepared the soft-float ABI for thumb mode).

From your backtraces the program crashes because the engine pointer is null. Apparently the asCreateScriptEngine() call didn't work, and returned null. Have you tried stepping into this function in the debugger to understand why it is not creating the engine instance?
