examples don't work #17

Closed porky11 closed 2 years ago

porky11 commented 7 years ago

I did everything as written in the readme. example: ./run.sh scratch/projects/games/rollball.cpp The first error I get is this:

/home/porky11/build/versor/scratch/projects/games/rollball.cpp: In Elementfunktion »virtual bool MyApp::onKeyDown(glv::GLV&)«:
/home/porky11/build/versor/scratch/projects/games/rollball.cpp:99:9: Fehler: »interface« wurde in diesem Gültigkeitsbereich nicht definiert
     if (interface.keyboard.code == 'i'){
         ^
wolftype commented 7 years ago

Hi -- the scratch folder is not entirely up to date yet with the newer API and not all .cpp files compile -- see this issue. That said, I've pushed a change which allows rollball.cpp to compile. If you find more that don't work, please feel free to add them here as a comment. Thanks!

porky11 commented 7 years ago

It seems to compile now, but in line 22 of run.sh the file ./bin/xInterface is not found

wolftype commented 7 years ago

I removed xInterface since it was an empty file. If you continue to receive errors about this file, try re-running ./build.sh (this will re-run the cmake file). Alternatively, you can run ./run.sh path-to-file --configure. The --confgure flag will also re-run the cmake file.

I tried it, but now I get errors like this when executing after the target is built 100% ./run.sh: Zeile 22: 30492 Speicherzugriffsfehler ./bin/$TARGET

wolftype commented 7 years ago

hi -- thanks -- I clearly need to clean this up, but for the moment please note that not all files in the scratch/project/ directories are working.

wolftype commented 7 years ago

i just realized perhaps you are just running ./run.sh without a path to a file? try for example: ./run.sh examples/xBasic.cpp

porky11 commented 7 years ago

your example doesn't work for me either

wolftype commented 7 years ago

thanks -- could you please be more specific? if you type the following: 

./buildAll.sh
./run.sh examples/xBasic.cpp

what exactly is the error being output?

porky11 commented 7 years ago

the first command does not generate warnings or errors the second outputs following:

Compiling and Running examples/xBasic.cpp
Directory is examples
Target is xBasic
[  0%] Built target gfx
[ 66%] Built target vsr
[100%] Built target vsrGfx
[100%] Linking CXX executable bin/xBasic
[100%] Built target xBasic
./run.sh: Zeile 22:  4837 Speicherzugriffsfehler  ./bin/$TARGET

(Speicherzugriffsfehler means memory access error)

wolftype commented 7 years ago

Strange to me that the error is coming from the run script itself, not the built executable. What happens if you run the built executable directly by typing:

./build/bin/xBasic On Sat, Apr 22, 2017 at 7:36 AM Fabio Krapohl notifications@github.com wrote:

porky11 commented 7 years ago

just the error

wolftype commented 7 years ago

I cannot duplicate this. What machine are you running on? Do all the examples behave this way?

porky11 commented 7 years ago

Gentoo linux, and yes, all examples, I tested

wolftype commented 7 years ago

Thanks for this information -- I am separating out the build steps to better debug what is happening. Would you mind trying the following branch and reporting back?

cd path/to/versor/repo
rm -rf build
git checkout gfx-update
git submodule update
./build.sh
./run.sh examples/xAlgebra.cpp

If the above works (it should spit out some numbers to your terminal), then also please try

./run.sh examples/xBasic.cpp

As always, please copy any output in your response. Thanks again!

wolftype commented 7 years ago

Oh, and please "git pull" before checking out the gfx-update branch

porky11 commented 7 years ago

I tried it again. xAlgebra.cpp works now. (I also switched to Arch Linux (i. e. Antergos)) But xBasic.cpp still gives this error:

wolftype commented 7 years ago

thanks -- seems to have gotten farther before crashing. if you could, please output a backtrace log and post it here so I can see what function call is having the "Speicherzugriffsfehler" memory access error.

wolftype commented 7 years ago

another test to try is to comment out line #19 (bindGLV()) of xBasic.cpp

porky11 commented 7 years ago

I don't know how to output a backtrace log. Seems to have something to do with gdb, but I don't use this, I normally print to debug. Removing bindGLV didn't change anything. btw. I remembered "Speicherzugriffsfehler (Speicherabzug geschrieben)" is called "Segfault (Core Dumped)" on english systems.

wolftype commented 7 years ago

If you have gdb you could spit out a backtrace with the bt command

gdb ./build/bin/xBasic
run

program segfaults here, then type:

bt

Hello! I seem to have the same problem. I am running arch linux on a modern computer. I followed the instructions on your website to compile versor (git .... ./build.sh ./run.sh ....). Then on the main branch,
