Error Ubuntu

[Unknown]

Hi, I made the build files, and them made a “sudo make install” inside the release folder.
After that, I tried to include the library on QT creator using #include <lf/Headers.h> and it did fine, but when i try to compile, it show me a lot of erros, like

/usr/local/include/fl/Engine.h:75: error: invalid conversion from ‘long int’ to ‘std::string* {aka std::basic_string<char>*}’ [-fpermissive]
virtual bool isReady(std::string* status = fl::null) const;

/usr/local/include/fl/Engine.h:94: error: invalid conversion from ‘long int’ to ‘std::string* {aka std::basic_string<char>*}’ [-fpermissive]
virtual Type type(std::string* name = fl::null, std::string* reason = fl::null) const;
^

/usr/local/include/fl/Engine.h:94: error: invalid conversion from ‘long int’ to ‘std::string* {aka std::basic_string<char>*}’ [-fpermissive]

Hi,

Thanks for your post.

Please, add the definition “-DFL_CPP11=ON” to your project.

Cheers.

Juan, first I would like to thank you for your quick answer and for that awesome library/program. I’m sorry to disturb you with these silly questions, but im new on linux and qt creator, so how can I add this definition on my project ?
Thanks again, cheers.

Hi,

In your project.pro, add:

CONFIG += c++11
DEFINES += FL_CPP11
QMAKE_CXXFLAGS = -std=c++11

I think this would do.

Cheers.
