You did good work.
It also compiles and installs on a rapsberry pi. 
I got "dietpi" underlying and installed it on top, works great, except xosview2, it doesn't compile.

Code:

g++-10 -Wall -Wextra -O2 -I/usr/include/freetype2 -I/home/dietpi/work/DVdist/DeskView/bin/Xosview/src/xosview2-2.3.1 -I/home/dietpi/work/DVdist/DeskView/bin/Xosview/src/xosview2-2.3.1/cmeter -I/home/dietpi/work/DVdist/DeskView/bin/Xosview/src/xosview2-2.3.1/linux -DHAVE_CONFIG_H -c serialmeter.cc -o serialmeter.o
serialmeter.cc: In member function ‘void SerialMeter::getserial()’:
serialmeter.cc:73:25: error: ‘inb’ was not declared in this scope; did you mean ‘int’?
   73 |     unsigned char lsr = inb(_port + UART_LSR);
      |                         ^~~
      |                         int
make[1]: *** [../Makefile.config:42: serialmeter.o] Fehler 1

The build script for Xosview is broken. Try building manually:

cd /opt/DeskView/bin/Xosview/src/xosview2-2.3.1
make clean
./configure
make -j4

This works for me on Devuan (64-bit ARMv8) on my Pi 3B. I noticed that your uname output says ARMv7 (32-bit?) so maybe there's a difference in some library or the compiler. You could also contact the developer: https://sourceforge.net/projects/xosview/



New icons, color schemes and apps are in the works. I'm attaching a couple previews
