OF: OF_LOG_ERROR: trying to delete a non indexed texture, something weird is happening. Deleting anyway

#4

not to put too fine a point on it, but as outlined in the guidelines, you are asked not to doublepost. it would be better to add additional information to the existing thread. I’m going to merge the two threads.

If nobody answers, it’s probably because nobody has an answer, or people haven’t seen your question yet - your query is only a day old.

#5

a stacktrace like that is not really very human readable. from the little i can see it seems to be happening when you close your application? what version are you using github or the one from the downloads section? it could be some problem in the destruction of objects inside OF since your code seems fine

#6

i am using of 007 from the downloaded section and yes after closing the apps those messages are being prompted

#7

i was running the app in terminal its showing these things but when i used it in codeblocks ide it ran perfectly fine any guesses on it

#8

This is just a though but since you’re on Linux, you should be able to run valgrind out of CodeBlocks after installing it, arturo has instructions here: http://forum.openframeworks.cc/t/memory-check-with-valgrind/1072/0

More info: http://valgrind.org/docs/manual/quick-start.html#quick-start.mcrun

Giving it a run in mem::check mode might track down what’s going on as your application exits b/c my guess is that something (probably a texture) is getting deleted twice somehow. Also, this is only happening in debug by any chance?

#9

thanks for the replies
i tried the valgrind memcheck in terminal its showing the messages but how to do the memcheck using codeblocks
and as i am very new to this can you please suggest me how to start solving those memory leaks
i am getting such prompts in terminal while i run vlgrind --leak-check=yes ./myTestProject

inside codeblocks you can try debugging your application to see where it’s crashing in the console you can do the same using gdb. but if it’s only crashing when closing the application i won’t worry about it

thanks for the reply again
i had again this problem i ran a code in terminal it didnt work saying segmentation fault and it ran perfectly fine in codeblocks any particular reason to these

#12

it could be that you are using the release version in console and the debug version in codeblocks (or the opposite) the only way to know why a segmentation fault is happenning is to debug the application

#13

i had no idea about that i tried to run the code in codeblocks in release mode and now its showing error as in terminal
so does it mean there are flaws in the code or should i be running the code in debug mode

in release mode its not running i am stuck here for a day please guide me

i finally got the problem whenever creating a new project using the python scripts its including the ofMain.h in both main.cpp and testApp.h so having that header once solves all the segmentation fault and glibc

:slight_smile:
thanks for all your support :slight_smile:

#16

mmh, i think the problem can be related with a bug in 007 with latest versions of gcc. are you using ubuntu 11.10? if so there’s a problem with the makefile where it doesn’t detect the dependencies properly and you need to:

make clean

and then make again or in codeblocks rebuild the whole project if you change a .h file. this is fixed in github, if you don’t want to download the whole repository you can just get the makefile from scripts/linux/template and substitute it in your download

#17

yes i am using ubuntu 11.10 and i did make clean and make it worked perfectly fine with no changes in header and all

thanks a ton arturo you are a saviour

and i just needed to ask can you provide me the lnk of how to use the github repositories i mean checking out the whole version
and some tutorials links if you can
thanks again

you can find some info on the OF git workflow and links to general documentation about git here:

hey i was trying the geometry shader example of OF 007 downloaded from the download section i tried the make clean and all it didn’t work i used the gdb debugger to get these

  
Program received signal SIGSEGV, Segmentation fault.  
0x00000000 in ?? ()  
(gdb) where  
#0  0x00000000 in ?? ()

#5  0x0805aa77 in ofRunApp(ofBaseApp*) ()

any specific solution to the example itself

Are you sure your card supports geometry shaders? Some older cards or drivers don’t.
