Error in `./sfml-app': free(): invalid pointer
« on: January 12, 2017, 10:36:45 pm »
I've been trying to run sfml on my computer following this tutorial http://www.sfml-dev.org/tutorials/2.0/start-linux.php
the program compiles without any errors, and I set up my link paths correctly, however once I run the program this message appears

Error in `./sfml-app': free(): invalid pointer: 0x000000000206ab38 ***

Following this is a long memory map that starts at my program's directory and works its way to the /dev folder

7ffb9fa63000-7ffb9fa64000 rw-s dfdf5000Aborted (core dumped)

Ubuntu version: 16.04
SFML-2.4.1 (GCC - 64-bit) 
g++ Version 5.4.0

I've already tried switched my g++ version to something before 5.4.0, however this does not change the outcome of the program at all.

 I would greatly appreciate some help. Thanks

Build the debug libs of SFML, find out where the error occurs and provide a stack trace.

I used this command to compile

g++-4.8 main.o -o sfml-app -L /media/matt/DataDrive/SFML-2.4.1/lib -lsfml-graphics-d -lsfml-window-d -lsfml-system-d

Then used this to compile

export LD_LIBRARY_PATH=/media/matt/DataDrive/SFML-2.4.1/lib && ./sfml-app

errors

Re: Error in `./sfml-app': free(): invalid pointer

Build as debug with the -g flag, so you actually get a meaningful backtrace.

What's your code?
Where did you get SFML from?

Error in `./sfml-app': free(): invalid pointer
« Reply #5 on: January 13, 2017, 10:52:11 am »
From the error messages it seems like you're linking the application object file twice. Can you provide your build command?

I used this command to compile  (the sfml project main.cpp is in a folder in the DataDrive directory if that helps at all)

g++-4.8 main.o -o -g sfml-app -L /media/matt/DataDrive/SFML-2.4.1/lib -lsfml-graphics -lsfml-window -lsfml-system

Alternatively when I run this command (replace main.o with main.cpp)

g++-4.8 main.cpp -o -g sfml-app -L /media/matt/DataDrive/SFML-2.4.1/lib -lsfml-graphics -lsfml-window -lsfml-system

the output is....

main.cpp:1:27: fatal error: SFML/Graphics.hpp: No such file or directory
compilation terminated.


The sfml window does briefly open for a second when using this command

g++-4.8 main.o -o sfml-app -L /media/matt/DataDrive/SFML-2.4.1/lib -lsfml-graphics -lsfml-window -lsfml-system

 but crashes and shows the error again

I read online about the free(): invalid pointer error, and found it is caused by trying to free objects from memory multiple times, or it Also happens if you have two libraries loaded into memory, which manipulate the same object name. Or two libraries of the same file name  identically named classes

I hope this helps, thanks.

It's fixed now, After deleting my project and reinstalling sfml and using g++-4.8 did it finally started to work.

Hi,

I am having a near identical problem with SFML 2.4.2 downloaded from this site. I am copying the example in the tutorial exactly, as in the code above. The code compiles but aborts with an invalid pointer when run. I did a fresh installation of Linux Mint 18.1 in case I broke something, but still have the same problem.

A trace in gdb gives me this:

I am not that familiar with Linux, C++ or SFML and I would appreciate your patience in helping me figure out what to do.

Thanks.

And where did you get SFML from?

Use the SFML version by your package manager or build SFML from source.
