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

The following table is a list of packages that should be installed in the VM. These should normally already be installed except the above.

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

# 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 and PRT_SIM_LIBS environment variables are new variables (2025-03-06) that contain the cups, 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:

The json-c and esmtp lines are recent additions (2025-03-06).

Any time changes are made to this from a terminal type:

setup_arm64lib

This will recreate the symbolic links in /opt/arm64include and /opt/arm64lib
