Linux build

[igorangst]

Lightweight adaptations for a linux build of kerberos, using ALSA or JACK drivers. Fixes a timing issue, where fast sysex messages were dropped. Also added a convenient build script that populates the kerberos release directory with the binary, dependency libs and a startup script. Have fun!

The build script fails because of missing Makefile. Forgot to add it?

[igorangst]

Hi,

the Makefile is being generated by qmake, which I forgot to call in the
build script. Should work now. Please test again.

It works fine now. Thanks! Just had to apt-get install qt5-default and all dependencies were installed (Ubuntu 14.04). Though, I don't know why but the change is not added in master branch. I had to add it myself into the build script even though I pulled from master.

Any plans to merge this?

Hi, tried this branch, but having troubles.
I tried to compile under jessie and 14.04.

joju@lx:usr/src/build/c64-midi-kerberos-git/qt# sh build-linux.sh
[] Building application

compilation terminated.
make: ** [mainwindow.o] Error 1
[*] Could not build application

I installed qt5-default as mentioned. In Jessie oder Ubuntu 14.04 there is not a file in/usr/include/x86_64-linux-gnu/qt5/QtGui/QAction only /usr/include/x86_64-linux-gnu/qt5/QtGui/QActionInterface.

What I am missing?

[meonwax]

I didn't use the build-linux.sh script, just compiled manually:

cd qt
qmake
make

Then the resulting kerberos.bin works just fine.
Why would i need the librarys bundled in a lib-directory as the build-linux.sh script copies them?
They are dynamically linked and just exist on my system.

Btw: I'm on Arch Linux with qt5 5.5.1 installed.

[igorangst]

As requested in the original issue, I tried to provide a more or less static build that could be deployed on systems that don't have all the libraries readily installed. It seems that my solution is not as portable as it should be. I suggest to split up the build script in a "just build" (i.e. qmake & make) and a "build release", which would include the library copying stuff. Any better idea?

[meonwax]

Would it be possible to statically link the libraries, so only the binary has to be deployed?

Edit: As i read here, the answer is: no.
Sorry, that conversation has been over a year ago :)

[j0ju]

I got it to build in a clean Debian/Jessie chroot. I have not tested the application yet, but it runs.

The following packages I had to install:

qt5-default
libasound-dev
This patch let my trouble go away, as in an qmake run Makefile and ui_mainwindowform.h are rebuild, if there is an ui_mainwindowform.h lying around from a former try it might fail.

With less white space fixes and the above patch you can find it here. j0ju@5a73573
