Gui error

[wangwenfeng0]

When I compile the source code, it will produce an access rights conflict in the xtree file, the function name is "template _Nodeptr _Lbound(const _Other& _Keyval) const { // find leftmost node not less than _Keyval _Nodeptr _Wherenode = this->_Get_data()._Myhead; // end() if search fails _Nodeptr _Pnode = _Wherenode->_Parent; } " the error information is : _Wherenode is nullpter

When I remove the gui source codes, it will be no error. How could I fix this problem, thank you very much.

What platform and compiler are you seeing this on? You may have set up your build environment incorrectly

I use the Windows 10 system with openframeworks 0.11.0, and the compiler is VS2017. I have tracked the error in the code, when in the ofxSimpleGuiConfig.cpp to run the ttf.load("data/type/Roboto-Regular.ttf", 9); it will produce the error.

I find the fonts_table size is zero, thank you for your reply, I will try to fix it.

Interesting, thanks for debugging. I'll compile it in Windows (I'm using a similar setup, vs2017, OF 0.11.0, Windows 10) and see if I can reproduce it.

You can work around it for the moment by changing the code to this:

    /* set up font */
    bUseFont = false;
//    ttf.load("data/type/Roboto-Regular.ttf", 9);

Can you get the latest code? It should be fixed.

[wangwenfeng0]

OK, I will test it, It should be fixed with your work, thank you.
