Compilation fails on armv6l (Raspberry Pi)

[jextrevor]

Trying to compile on my Raspberry Pi causes make to fail:

../lib/libAngelscript.a(as_callfunc.cpp.o): In function `CallSystemFunction(int, asCContext*, void*)':
as_callfunc.cpp:(.text+0x754): undefined reference to `CallSystemFunctionNative(asCContext*, asCScriptFunction*, void*, unsigned long*, void*, unsigned long long&)'
collect2: error: ld returned 1 exit status
Sources/CMakeFiles/OpenSpades.dir/build.make:5424: recipe for target 'bin/openspades' failed
make[2]: *** [bin/openspades] Error 1
CMakeFiles/Makefile2:168: recipe for target 'Sources/CMakeFiles/OpenSpades.dir/all' failed
make[1]: *** [Sources/CMakeFiles/OpenSpades.dir/all] Error 2
Makefile:137: recipe for target 'all' failed
make: *** [all] Error 2

This git project solves the problem by using a newer version of Angelscript. Any chance this is possible for openspades?

[jextrevor]

It is true that the version of Angel Script has been updated, however compilation still seems to fail on armv6l.

I know very little about how to use CMake or how compilers work at all, but after reading a bit about the changes that SuperTuxKart made to compile on ARM, I think CMake is the culprit.

Just see the difference between the OpenSpades CMakeLists.txt and the SuperTuxKart CMakeLists.txt

Specially this:

+if(${CMAKE_SYSTEM_PROCESSOR} MATCHES "^arm")
+    enable_language(ASM)
+    if(CMAKE_ASM_COMPILER_WORKS)
+        set(ANGELSCRIPT_SOURCE ${ANGELSCRIPT_SOURCE} ../../source/as_callfunc_arm.cpp ../../source/as_callfunc_arm_gcc.S)
+        set_property(SOURCE ../../source/as_callfunc_arm_gcc.S APPEND PROPERTY COMPILE_FLAGS " -Wa,-mimplicit-it=always")
+    else()
+        message(FATAL ERROR "ARM target requires a working assembler")
+    endif()
+ endif()

I made a simple Gist diff here.

[jextrevor]

Yes, I saw the same thing. I'll try to edit the CMakeLists.txt to get compilation to work, then I might submit a pull request.

@jextrevor Great! It'd be very cool to have OpenSpades running on Raspberry Pi.

[ghost]

jextrevor please explain here what you did and how you got it running because im having this error on pi 3B with armv7 here

[jextrevor]

@Tapmemer see above message from feikname. I did manage to compile it, but didn't manage to get it running.

[feikname]

@jextrevor could please post the 'SystemMessages.log' and the crash dump, if it exists, of when you tried to run it?

[jextrevor]

@feikname where might I find the SystemMessages.log?

Here is the output of the program when I try to run it:

[jextrevor]

The problem seems to be with the GetReportLineColor function. Somehow this function is being called with an "invalid index". I'm going to see if I can find where this function is being called, and why an invalid index is being passed.

[jextrevor]

I was able to recompile the project so that it would skip the start screen altogether, however, now I run into this error:

2017/03/06 10:53:16 [Runner.cpp:48] [!] Unhandled exception in SDLRunner:
GL error Invalid Value in virtual void spades::gui::SDLGLDevice::TexImage2D(spades::draw::IGLDevice::Enum, spades::draw::IGLDevice::Integer, spades::draw::IGLDevice::Enum, spades::draw::IGLDevice::Sizei, spades::draw::IGLDevice::Sizei, spades::draw::IGLDevice::Integer, spades::draw::IGLDevice::Enum, spades::draw::IGLDevice::Enum, const void*) at /home/pi/openspades/Sources/Gui/SDLGLDevice.cpp:873

[jextrevor]

Recompiled yet again to use the software renderer by default. Main screen starts fine, albeit very slowly. All text is a blue-ish color. I'm able to change settings and select a game, but when I try to actually connect, OpenSpades segfaults.

[jextrevor]

I'm trying with release 0.1.1-c, instead of latest.

[feikname]

@Jextrevor The SystemMessages.log file in inside the user resource directory, which should be located at $XDG_DATA_HOME/openspades/Resources

If XDG_DATA_HOME is not set (you can see this by looking at the output of echo $XDG_DATA_HOME), then the file is located at the ~/.local/share/openspades/Resources folder (If I'm not mistaken)

[jextrevor]

Software rendering is working great on a Raspberry Pi 3. Still segfaults when placing blocks. I've found 640x480 to work the best (at fullscreen) with no undersampling.

@TapMemer sorry for the late response.

If you're atill interested in running OpenSpades on arm, take a look at the OpenPides fork master branch.

[tigercoding56]

really why dont we just take the code from openspides clean it up and then add it to openspades so that we do not have to worry about it anymore ?

@TapMemer sorry for the late response.
