AppsGettingStarted.md is inconsistent with GettingStarted.md

[mcharleb]

Both documents describe different ways of installing the qrlSDK.

@rkintada can you have a look at this and decide what method you want to use?

@bharath374 This is indeed confusing. I just tried to build the camera-deamon using the description under ii. Camera Programming and failed. This could be because I installed the qrlSDK using the cross_toolchain repository, or because it is anyway broken. Here is what I did: In XXX/camerad-sample/media/camera-daemon I typed: make -f sdk_use.mk all and got the following error:

legatus@legatus-ThinkPad-T440p:~/camerad-sample/media/camera-daemon$ make -f sdk_use.mk all
g++  -std=c++11 -DHAVE_SYS_UIO_H -I /usr/include/live555 -I /usr/include/omx -I /usr/include/linux-headers/usr/include -I src  -c -o src/camerad.o src/camerad.cpp
In file included from src/camerad.cpp:41:0:
src/camerad.h:33:20: fatal error: camera.h: No such file or directory
compilation terminated.

Then in camera-deamon/sdk_use.mk I replaced $(SDKTARGETSYSROOT) with $(HEXAGON_ARM_SYSROOT)

As the file still wasn't found I added the line CPPFLAGS += -I $(HEXAGON_ARM_SYSROOT)/usr/include

as on instance of the camera.h file was suited there. However, new errors showed up then:

.... I will now try to install the qrlsdk as described here AppsGettingStarted.md and see whether these error persist.

[skye-AL]

Reinstalling the qrlsdk as described here AppsGettingStarted and installing the 32 bit libraries sudo apt-get install zlib1g:i386 and then following the instructions here CameraProg.md worked. I lack knowledge to support you here, but one single installation of the qrlSDK would be nicer (see also gcc-linaro-arm-linux-gnueabihf-4.8 vs 4.9).

[bharath374]

The installation instructions have now been cleaned up, and there is now only one documented procedure. Please see: https://github.com/ATLFlight/ATLFlightDocs
