Odroid C1 build problems (armv7, OPENGL ES) #19

Closed MagaTailor closed 9 years ago

MagaTailor commented 9 years ago

Build fails on Linux against a gles-only SDL2:

For some reason, even though LDFLAGS=-ldl is passed to make -j4 I'm getting these:

Linking CXX executable ../../../../jsonconvert
/usr/bin/ld.bfd.real: ../../../Debug/lib/liblua5.2.a(loadlib.c.o): undefined reference to symbol 'dlsym@@GLIBC_2.4'

collect2: error: ld returned 1 exit status
make[2]: *** [../soundmapper] Error 1
make[1]: *** [src/caveexpress/tools/CMakeFiles/soundmapper.dir/all] Error 2

and afterwards the build finally fails with:

Linking CXX static library ../../../Debug/lib/libui.a
[ 65%] Built target ui
make: *** [all] Error 2

Doing a make -j4 and then after the above dlsym errors finishing with LDFLAGS=-ldl make ends with:

Could you please post the first few lines for the cmake output - and please run make with make VERBOSE=1

mgerhardy commented 9 years ago

about the GLenum error: see src/modules/gfx/CMakeLists.txt - this is currently included if the platform is not android - because android is basically what you wanna compile it for, too (arm + gles).

That means we have several options - the best would maybe be to provide a dedicated toolchain file for cmake which exports a proper system name so I can identify it later on. Another option would also be to just skip the GL1Frontend code compilation if SDL_VIDEO_OPENGL is not 1

MagaTailor commented 9 years ago

I'm going to provide the requested info shortly. For now I'd like to commend the idea of disabling the GL backend completely - even though this system has a software Mesa implementation, the only hardware accelerated option is GLES 1/2 coming from the Mali chip.

Indeed it builds fine now. I'm getting a crash on startup though - would you like to continue here or move to a new issue?

MagaTailor commented 9 years ago

No wait, the build process likes x86 too much :)

I tried a Release build but got:

g++-4.9.real: error: unrecognized command line option ‘-msse3’

You probably meant -mfpu=neon ;)

EDIT: Just as I thought the release build starts and works fine.

mgerhardy commented 9 years ago

looks like the lua error is related to #18

Could you please reexecute cmake and attach the lines of this output:

message(STATUS "Target processor: ${CMAKE_SYSTEM_PROCESSOR}")
message(STATUS "Host processor: ${CMAKE_HOST_SYSTEM_PROCESSOR}")

(you need to pull to latest master)

MagaTailor commented 9 years ago

-- Target processor: armv7l -- Host processor: armv7l

mgerhardy commented 9 years ago

Thanks a lot - please give latest master a try. Should be fixed now.

MagaTailor commented 9 years ago

Yeah, that's what I manually did yesterday - the release build is ok now. I've also built it on my old 32bit Athlon box which only has OpenGL 1 (and sse) - the game runs smoothly with nvidia binary drivers but it has to be started with -set frontend sdl the first time, otherwise it crashes after automatically choosing GL3.

The lua issue is also present on that 32bit x86.

Thanks!

mgerhardy commented 9 years ago

The lua issue is also present there? I thought you are able to run it. What exactly is the output? segfault?

mgerhardy commented 9 years ago

ah - amd64. no sse3 - there was this cmake module FindSSE.cmake - but I found this a little bit overkill. But as far as I can see there is no way around it if I wanna support more platforms and still use -msse3

MagaTailor commented 9 years ago

The default debug build has the lua issue on both platforms whereas the release doesn't.

If you meant to see the GL3 segfault, here you are:
