Q Light Controller+

Hi!

I'm trying to build QLC+ on a RPI for several weeks but always end with an error due to linked libs:

g++ -Wl,-O1 -o bus_test bus_test.o moc_bus_test.o -L../../src -L/usr/lib/arm-linux-gnueabihf -lqlcplusengine -lQtTest -lQtScript -lQtXml -lQtGui -lQtCore -lpthread

It seems this error occurs when the libs aren't at the end of the line of the gcc command, but even by moving ($LIBS) at the ends of the lines in the Makefiles in which they weren't, I just don't get it.

By the way, fftw dev files are installed:
ii libfftw3-3:armhf 3.3.2-3.1 armhf Library for computing Fast Fourier Transforms
ii libfftw3-bin 3.3.2-3.1 armhf Library for computing Fast Fourier Transforms -
ii libfftw3-dev:armhf 3.3.2-3.1 armhf Library for computing Fast Fourier Transforms -

Any idea?

Aurelien, you posted again the same thing and again on the wrong forum.
https://sourceforge.net/p/qlcplus/discu ... /e3231741/

Can you please give more details about what you're doing ?
For example the GCC version.
Also, try with QLC+ 4.7.0 instead of RC1.

Oh sorry, I thought the first one didn't reach anything, and had to subscribe to sourceforge.

As far as gcc is concerned, here it is:
dpkg -l gcc*

I'm with raspbian stable, and I'm going to try the 4.7.0 right now, but it takes a bit on the RPI (don't know how to build something on an arch for another arch, and don't have the time to look for this right now).

(weird, I do have post a comment, but it doesn't appear - hope I'm not messing up again!!)

So, I've tried with 4.7.0, but I finally reach an error:

I suppose I would have to build it without ola support, but didn't find how by reading make -h and qmake -h.

Hi Aurelien,

I recommend reading the [Linux Build HOWTO](https://github.com/mcallegari/qlcplus/w ... uild-HOWTO).

To exclude some plugins from the build:

>If you want to exclude some [plugins] from the build process then just comment them out by placing the character # at the beginning of the plugin line in the file plugins/plugins.pro For example:
#unix:SUBDIRS += ola


To install the OLA (notice that you may need to install also additional packages to compile OLA. I needed: *bison flex uuid-dev libcppunit-dev libprotobuf-dev libprotoc-dev*)

>Acquire the latest tarball from the OLA webiste:
http://code.google.com/p/open-lighting/downloads/list
>
>Extract the package and enter into the OLA folder. Then, as usual, type:

>./configure --prefix=/usr
make
sudo make install

OK, thanks, so I removed ola from the plugins, and it finally built OK. But I couldn't install, it seems the /usr/share/qlcplus folder is not created :

(I've tried both with sudo and sudo su -)

I precise I already managed to build QLC+ on a "standard" (AMD64) Debian machine, but on RPI, I'm way more noob!

Can you please prefix all your command with LANG=C, like this; LANG=C
sudo make install

OK, correct, the problem came from the use of checkinstall.
It's now built and working.
Let's see what it gives.
