attempting free on address which was not malloc()-ed

I'm getting this error:

SUMMARY: AddressSanitizer: bad-free ??:0 operator delete(void*)
==13005==ABORTING

When using this code:
`#include <anax/anax.hpp>
int main()
{

// anax::World *world = new anax::World;
anax::World world;
}`

So I don't know what to do.

Interesting, I'm going to have to see if I can reproduce on Linux. I wouldn't have expected that this would occur.

What compiler are you using? GCC 4.9?

[jvikstrom]

gcc (Ubuntu 4.9.2-0ubuntu1~14.04) 4.9.2
I'm also using linux. VERSION="14.04.3 LTS, Trusty Tahr"
(It's Mint 17)

[jvikstrom]

/usr/include/c++/4.9/bits/unique_ptr.h:236: error: undefined reference to `anax::World::SystemDeleter::operator()(anax::detail::BaseSystem*) const'

That is the error I get when doing this.

`
#include <anax/anax.hpp>
int main()
{

    anax::World *world = new anax::World;
    delete world;
    //anax::World world;
}

`

I must have done something wrong when I installed anax, right?

[miguelmartin75]

Hm before you could compile your program and now you can't? Try this:

c++ main.cpp -lanax -std=c++11

[jvikstrom]

./bin: error while loading shared libraries: libanax.so.2: cannot open shared object file: No such file or directory

I have like zero experience linking libraries using the terminal as I usually only use cmake.

But I suppose that error message means I didn't install it correctly.

[miguelmartin75]

That message means it can't find libanax.so.2. You have to give the compiler the path to where libanax is located, if installed by cmake this will likely be in /usr/local/lib. e.g.

c++ main.cpp -L/usr/local/lib -lanax -std=c++11

[jvikstrom]

I had to add the path to anax to my LD_LIBRARY_PATH, then it worked.
It compiled successfully and ran without segmentation faults. (This is when I compiled through the terminal)

[miguelmartin75]

If you compile with -fsanitize=address does it produce the same error you were describing?

[jvikstrom]

Unless doing these two commands:
LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

it gives me this error when running it: ./bin: error while loading shared libraries: libanax.so.2: cannot open shared object file: No such file or directory

Otherwise it runs and compiles fine when I compile through the terminal.

[jvikstrom]

The problem seemed to be was that I linked ${ANAX_LIBRARY_DEBUG} instead of ${ANAX_LIBRARY_RELEASE} in cmake. When I linked the release one it works.
