Verifier

Build 32 bit version

To build x86 version, g++ compiler is needed. Go to FCS Server folder and run:

make x86

Build 64 bit version

To build ARM64 executable on the Linux x86, AArch64 toolchain is needed. E.g. on Ubuntu 18, install:

apt-get install g++-aarch64-linux-gnu

Go to FCS Server folder and run:

make aarch64

Build for All architectures

To build for both architectures, run:

make all

Output files:

fcsServer.x86
fcsServer.aarch64
fcsServer where fcsServer is a copy of fcsServer.aarch64

Build with DEBUG symbols and NO security protections

make DEBUG=1 all

Running FCS Server on HPS (Yocto linux)

After building FCS Server, copy following files to HPS running Yocto OS to one folder:

fcsServer - executable
fcsServer.service - service unit file used by systemd
install.sh - install script

To change default log level (Info) or default port (50001), edit fcsServer.service file:

ExecStart=/usr/sbin/fcsServer [PORT_NUMBER] [LOG_LEVEL]

Possible log levels: Debug, Info, Error, Fatal

To install FCS Server, run install.sh within the folder script is located, with root privileges. FCS Server will automatically start and will persist after system reboot.

SYSTEMCTL commands:

Checking FCS Server status
```
systemctl status fcsServer
```

Start/stop FCS Server

systemctl start fcsServer
systemctl stop fcsServer

Restart FCS Server
```
systemctl restart fcsServer
```
Changing FCS Server settings after installation: edit service unit file /etc/systemd/system/fcsServer.service, reload systemd manager configuration
```
systemctl daemon-reload
```
and restart service
```
systemctl restart fcsServer
```
