Development VM Technical Information

Fedora Packages

The development VM has a number of pre-installed packages. Due to new features that are added to the library it may be necessary to install some additional packages.

The json-c library is now used for graphical CUPS ticket formatting. From a terminal window type:

sudo dnf install json-c-devel

The libesmtp library will be used to allow sending tickets as emails.

sudo dnf install libesmtp-devel

Environment Variables

The development VM uses a number of environment variables. To review or edit these from a terminal window type kate /etc/profile.d/arm825env.sh

#Setup environment variables for ARM825 development

AARCH64=/opt/armv8a
export AARCH64

AARCH64MX8M=/opt/armv8a-mx8m
export AARCH64MX8M

export DSPWIDTH=1280
export DSPHEIGHT=800

export UI_LIBS="wayland-client -lwayland-cursor -lxkbcommon -lffi -ljpeg -lpng -lpixman-1 -lfreetype -lz"
export CURL_LIBS="curl -lcrypto -lssl -lidn2 -lunistring"
export GLIB_LIBS="glib-2.0 -lgio-2.0 -lgmodule-2.0 -lgobject-2.0 -lpcre -lmount -lblkid"
export NM_LIBS="nm -lsmime3 -lnss3 -lnssutil3 -lnspr4 -lplds4 -lplc4 -ludev"
export CAIRO_LIBS="pango-1.0 -lpangocairo-1.0 -lharfbuzz -lfribidi -lcairo -lfontconfig -lGLESv2 -lEGL -lexpat -luuid -lGAL -lVSC -lwayland-server -ldrm -lgbm -lgbm_viv"
export CAIRO_SIM_LIBS="pango-1.0 -lpangocairo-1.0 -lharfbuzz -lfribidi -lcairo -lfontconfig -lGLESv2 -lEGL -lxcb-shm -lxcb -lxcb-render -lX11 -lXext -lXrender -lXau -lXdmcp -lexpat -luuid -lwayland-server -ldrm -lgbm"
export CUPS_LIBS="cups -lavahi-common -lavahi-client -ldbus-1 -lsystemd -lzstd -lcap"
export PRT_LIBS="cups -lavahi-common -lavahi-client -ldbus-1 -lsystemd -lzstd -lcap -ljson-c -lesmtp -lssl -lcrypto"

# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/opt/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin/:/opt/freescale/usr/local/gcc-4.4.53-uclibc-0.9.53/m68k-uclinux/bin/

The PRT_LIBS environment variable is a new variable that contains the CUPS_LIBS contents, json-c, esmtp, ssl, and crypto to facilitate the new ticket printing features for graphical tickets and emails.

After making changes to this it may be necessary to restart the VM.

Project helper setup_arm64lib

The folders /opt/arm64include and /opt/arm64lib contain symbolic links to various header and library files so that apps can refer to these folders to reduce the complexity of app properties.

The file /home/user/bin/setup_arm64lib is a script used to update these folders:
