PiBox

There are now two template implementations for using the new installed toolchain and staging tree.
libleak shows how to use them with GNU Make based builds.
picam shows to use them with autoconf based builds.
The set of builds to port to each example are taken from the metabuild configurations.

GNU Make builds to port (these support -showconfig in cross.sh)

• mjpg-streamer : cmake example
• omxplayer
• pmsui
• piboxwww : supports -P for PiSentry
• psplash : supports -T to enable for TFT displays
• piconf : supports -S <system> - needs fix to clamp to known values
• ironman+www : supports -S <system>
• ironman+monitor
• ironman+ironmancfg
• lcdshow
• libleak

Autoconf builds to port (these do not have -showconfig support in cross.sh)

• appmgr : supports -P for PiPlayer
• launcher supports
  

  -f             Force use of colored icons
  -k             Make a kiosk launcher
  -p             Make a piplayer launcher
  -P             Make a piplayer launcher but add terminal app
  -s             Show the config used to run the build.
  -T             Install test configs with app
  -x             Make a xeon launcher
  

• libpibox
• pigtk
• piboxd
  

  -a             If set, then package for AutoKiosk System.
  -p             If set, then package for PiPlayer System.
  -S             If set, then package for PiSentry System.
  -x             If set, then package for Xeon System.
  

• piclock : supports -P for PiPlayer
• pipics
• pnc
• videofe
  

  -k num         Kiosk modes
                 0: Non-kiosk (normal media center mode)
                 1: touchscreen kiosk (video picture frame)
                 2: auto-kiosk (auto-starting, looping videos)
  

• musicfe
• picam : supports -P for PiSentry
• pixm
• pinet : supports
  

  -S             Set the SSID for the node.
  -x             Enable use on Xeon.
  

• ironman+imrest
• ironman+sensors
• raspi2fb
• pistore
• pistore+pistoreweb
• (xeon) pidialer - needs xeon build ported to install toolchain and staging tree.

After these are done, the metabuilds need to be updated to support the changed build processes, specifically by using cross.sh on all apps.
Then the various sandboxes need to be updated, rebuilt and installed.
Then the metabuilds for apps needs to be tested against each board type. A -b option for boards needs to be added, which will also determine which Systems are meaningful to the build.

• rpi1
  • Player
  • Kiosk
  • AutoKiosk
• rpi2
  • autokiosk
  • ironman
  • kiosk
  • media
  • pisentry
  • pistore
  • player
• rpi4
  • media
  • pisentry
• xeon

Finally, the new builds + apps need to be tested on hardware.

RM #1224: Migrated to app-defs.mk + docker + cross.sh usage.
RM #1224: Disable AC features of app-defs.mk.

Build:
./cross.sh -b rpi2
./cross.sh -s -b rpi2
./cross.sh -d -b rpi2
./cross.sh -b rpi -t "clobber app-init"
./cross.sh -c

Other options are app specific, such as -T or -S.

cmake programs need to be told where the toolchain stuff is.

First, take a look at these examples and this explanation. The latter gives an example that could be turned into a template under $(HOME)/.pibox. The app-defs.mk can copy this to the top of the build directory and replace tags with build specifics, like the toolchain and staging tree locations based on select board for the build. Then cmake builds can references it

-DCMAKE_TOOLCHAIN_FILE=$(stage)/$1/toolchain.cmake

But this doesn't actually set the pkg-config stuff, just the toolchain stuff.

If it can be set in the environment and used by cmake, try this.

    PKG_CONFIG_LIBDIR=${STAGING_DIR}/usr/lib/pkgconfig:${STAGING_DIR}/usr/share/pkgconfig
    PKG_CONFIG_SYSROOT_DIR=$STAGING_DIR

Alternatively, try modifying this and passing it as

-DCMAKE_TOOLCHAIN_FILE=$(stage)/$1/toolchain.cmake

string(REPLACE "/share/cmake" "" RELOCATED_HOST_DIR ${CMAKE_CURRENT_LIST_DIR})
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_VERSION 1)
set(CMAKE_SYSROOT ${RELOCATED_HOST_DIR}/sysroot)
set(CMAKE_FIND_ROOT_PATH ${RELOCATED_HOST_DIR}/sysroot)
set(CMAKE_PROGRAM_PATH ${RELOCATED_HOST_DIR}/../tools/bin)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_C_COMPILER aarch64-qsys-linux-gnu-gcc)
set(CMAKE_CXX_COMPILER aarch64-qsys-linux-gnu-g++)
