QGroundControl for Linux

[DUKE40]

Hi Max,

I don't think ignoring the errors is the right solution, as the command sh ./get-festival.sh ends with the following erros:
testinstall.sh: 41: testinstall.sh: ../bin/festival: not found
make[1]: *** [testinstall] Fehler 1
make: *** [test] Fehler 2
./get-festival.sh: 33: ./get-festival.sh: bin/festival: not found

meaning the application festival could not be build. I am not sure if it is needed by QGroundControl, but I assume that it is needed, otherwise there would be no need to have it build according to the documentation.
And Building QGroundControl anyway ends with an error an no application:
/usr/include/osg/Math: In function 'bool osg::isNaN(float)':
../qgroundcontrol/src/QGC.h:55:18: error: 'std::std' has not been declared
#define isnan(x) std::isnan(x)
^
/usr/include/osg/Math: In function 'bool osg::isNaN(double)':
../qgroundcontrol/src/QGC.h:55:18: error: 'std::std' has not been declared
#define isnan(x) std::isnan(x)

make: *** [build-release/obj/MainWindow.o] Error 1
03:33:00: The Process "/usr/bin/make" was ended with the return value 2.
Error while creating/deploying the project qgroundcontrol(Kit: Desktop)
While processing step 'Make'

So, yes I tried that as well and failed as well. The error seems not to be related, but the result still is not what is expected.

I tried apt-get install festival-dev as well, but it did not solve the issue.

There are some patch arround for this issue. I didn't remember where I found that patch for festival.
Ignoring didn't work.

That is good to know, that it is not an isolated issue, but Google was not able to redirect me to the mentioned patches, or at least I was not able to find them.
Further Qt Creator fails to compile with the error:
/usr/include/osg/Math: In function 'bool osg::isNaN(float)':
/usr/include/osg/Math:118:46: error: 'std::std' has not been declared
/usr/include/osg/Math: In function 'bool osg::isNaN(double)':
/usr/include/osg/Math:119:47: error: 'std::std' has not been declared

I have no idea what is wrong and how it could be corrrected. In this case as well I was not able to google the solution.

"osg" is OpenSceneGraph. I have no idea why it can't find "std" lib. You don't really need OSG... to build w/out, go into qgroundcontrol.pri and comment out the relevant code block @ lines 207-219.

To build w/out speech, comment out the QtSpeech include in qgroundcontrol.pro line 96. Then open up src/GAudioOutput.cc and .h, and comment out every occurrence of "QtSpeech" (2 in .h) and the variable "speech" (3 in .cc). That should work, though it's possible I forgot some part. (And yes, there really should be a #define macro to exclude speech, but I haven't gotten around to it.)

Thanks Max, that worked, I have now again a running QGroundControl on my linux box.

Hello Autoquad Community:-),
i got it compiled under Ubuntu 14.04 by installing the Packages festival; festival-dev speech-tools libsdl-console libsdl-console-dev libsdl1.2-dbg libsdl1.2-dev.
I only got the errors solved by copying the files of those packages from /usr/include/speech-tools and /usr/include/festival to the project directory of the qgroundcontrol application.

Hello Johannes, and welcome.

Good to know, thanks. Building with festival seems to need a different "trick" for everyone. I should probably point a link in the readme to this thread.

Did you build the latest master version, or a branch? master is a bit experimental at the moment, but we'd appreciate testing the new serial library and functions. The 1.4 branch is the last released stable version.

BTW, I did add a macro for building w/out speech altogether (instructions in readme).

Cheers,
-Max

Hello Max,
i built both, the Master Branch and Branch 1.4. Both versions had the same issues with festival.
To have a successful build in Ubuntu you have to install qt version 4.8.6 and qt creator.
In qt creator go to tools --> options --> build & run --> [qt versions] to check the version of qt used by qt designer.
Install the required packages by typing
"sudo apt-get install festival festival-dev speech-tools libsdl-console libsdl-console-dev libsdl1.2-dbg libsdl1.2-dev"
Download the latest stable source from github and open the project file in qt-creator.
Now you have to tell qt designer where the include files of festival and speech-tools are, by changing the following line of code in the file "qgroundcontrol.pro"
Line 77-81
#################################################################
# EXTERNAL LIBRARY CONFIGURATION

# EIGEN matrix library (header-only)
INCLUDEPATH += libs/eigen

to

#################################################################
# EXTERNAL LIBRARY CONFIGURATION

# EIGEN matrix library (header-only)
INCLUDEPATH += libs/eigen \
/usr/include/festival \
/usr/include/speech_tools

Cheers Johannes:-)

Hi Johannes,

Thanks for the tips. I agree, specifying the path to the shared festival and speech_tools is a better way to go than the current setup (using "private" versions the get-festival.sh script would download). I think your changes will be better placed in /libs/QtSpeech/QtSpeech.pri, in the Linux-specific section.

Cheers,

Hi Max,
i added the following lines to my /libs/QtSpeech/QtSpeech.pri:
48-49
INCLUDEPATH += /usr/include/speech_tools
INCLUDEPATH += /usr/include/festival
56-57
LIBS += -L/usr/lib -lFestival
LIBS += -L/usr/lib/speech_tools/lib -lestools -lestbase -leststring

This works for me;-).

The whole file looks like this now:

I don't know if there are prettier ways for adding include and library paths.
