Qt and Fuzzylite

[Unknown]

Hi Juan,

I need to use the library with a Qt creator 5.3, but when i try to build it by running the “build.bat” file, i got only this error file in the release and debug folders

/////////////////////////////////////
Compiling the CXX compiler identification source file “CMakeCXXCompilerId.cpp” failed.
Compiler: cl
Build flags:
Id flags:

The output was:
The system cannot find the file specified

Compiling the CXX compiler identification source file “CMakeCXXCompilerId.cpp” failed.
Compiler: cl
Build flags:
Id flags: -c

The output was:
The system cannot find the file specified

Checking whether the CXX compiler is IAR using “” did not match “IAR .+ Compiler”:

I’m also tryed to simply add the .lib and includepath to my project

but it doesnt work and shows exactly the errors as the following link.

Hi,

for the build.bat, you need to open the console window using the Visual Studio Console (or Terminal), which will run some commands to update the paths for binaries in your system. The problem there seems that CMake is not able to find the compiler.

As for the following code:

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../../../fuzzylite-5.0/ -lfuzzylite
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../../../fuzzylite-5.0/ -lfuzzylited
else:unix: LIBS += -L$$PWD/../../../../../../fuzzylite-5.0/ -lfuzzylite

INCLUDEPATH += $$PWD/../../../../../../fuzzylite-5.0
DEPENDPATH += $$PWD/../../../../../../fuzzylite-5.0

The problem is that you are not finding the library. Please use the full path to fuzzylite instead of a relative ../../../ to prevent unnoticed errors. Also, some times things are funny with dynamic libraries, so you may also try using -lfuzzylite-static and -lfuzzylite-staticd instead of the dynamic versions.

Furthermore, you need to ensure that the path to fuzzylite is correct. For example, the INCLUDEPATH needs to point to the fuzzylite directory that contains folders fl and src, such that doing cd $FL_HOME/fl is a valid path to the headers. Likewise, you need to make sure that the library files are available in the fuzzylite directory or change accordingly: LIBS+=path/to/fuzzylite/release/bin/, such that the libraries are in path/to/fuzzylite/release/bin/.

Hope this helps.
