qtfuzzylite Linking problem

[Unknown]

Hi,

since version 4.0, qtfuzzylite does not link properly anymore on the following system configuration:
– Ubuntu 12.04 LTS
– use qt4
– fuzzylite only backtrace enabled
– qtfuzzylite no debug, use_float

All linking errors are related to “undefined reference to” for any call in the source, for instance:
> CMakeFiles/qtfuzzylite.dir/src/About.cpp.o: In function `fl::qt::About::setup()’:
> About.cpp:(.text+0x1798): undefined reference to `fl::fuzzylite::fullname()’

Furthermore, there’s another small issue about the generated ui_*.h files from the ui xml format from qt. Infact I needed to copy manually these (generated in the “build” directory) into fl/qt path (or a path setting to include the build dir is missing…)

Correction on the first issue:
apparently fl-shared is not a path to the folder, but the path to the target library. Is it correct?

Hi,

yes, fl-shared is the path to the target library.

I would recommend you make sure to clean CMake derived files using the clean.sh file.
Also, I think you will have trouble building from source using -DFL_USE_FLOAT=ON. If you do, please use double precision instead by setting -DFL_USE_FLOAT=OFF or just not using the flag -DFL_USE_FLOAT (by default is OFF). I am working on some compiling issues I found using floats instead of double.

Hi,

thank you for providing feedback!

Indeed, there were errors building fuzzylite 4.0 using -DFL_USE_FLOAT=on.
I have fixed them and updated the sources.
Please, download the sources again from http://www.fuzzylite.com/downloads and let me know if your issue was resolved.
