I have Ubuntu 20.04 on a desktop with an old i7 CPU and 16 GiB of RAM.

Here are the commands I ran to compile Unreal 4.27:

./Setup.sh
./GenerateProjectFiles.sh
make -j 4
make -j 4 ShaderCompileWorker

TEST1 := $(shell command -v sh)
TEST2 := $(shell /bin/sh -c 'command -v sh')
all:
        $(info TEST1 = $(TEST1))
        $(info TEST2 = $(TEST2))

Running make prints

make: command: Command not found
TEST1 = 
TEST2 = /usr/bin/sh

Weird. Why does the default shell not know the command built-in? And what is the defaul ...

I downloaded the angryIP scanner in 2.x and 2.21. The old version, because I need to run it on a Tegra (ARM) processor. The universal plattform .deb fails to install, so it seems not to be that universal... However, the archive comes with all the .h and .cpp files, but no makefile.am, makefile.im, configure, readme or whatever. I tried a couple of hours now with the auto(re)conf tools, but I fail.
