Issues with installing blugon

[mqbpjfg2]

Hi,

I had blugon intalled and working fine on linux mint but after re-installing my linux mint I don't seem to be able to install blugon again.
Here is the error I get:

~/blugon$ make
sed "s|MAKE_INSTALL_PREFIX = '.*'|MAKE_INSTALL_PREFIX = '/usr'|g" blugon.py > blugon
sed "s|MAKE_INSTALL_PREFIX|/usr|g" systemd/user/blugon.service > blugon.service
gzip --best --force --keep blugon.1
cd backends/scg && make build
make[1]: Entering directory '/home/flo/blugon/backends/scg'
gcc -O2 -std=c11 -D_POSIX_C_SOURCE=200809L -Wall -Wextra -Wpedantic -I/usr/X11R6/include -L/usr/X11R6/lib -lX11 -lXrandr -o scg scg.c
scg.c:1:10: fatal error: errno.h: No such file or directory
 #include <errno.h>
          ^~~~~~~~~

make[1]: *** [build] Error 1
make[1]: Leaving directory '/home/flo/blugon/backends/scg'
Makefile:5: recipe for target 'build' failed
make: *** [build] Error 2

I have tried with a older release (1.11.4) but I get the same mistake... I'm quite puzzled because it was working just fine before...
Any idea what I could try?

Thank you!

errno.h is part of the C Standard Library.

I am not familiar with Linux Mint's package repository, but Archlinux and nixpkgs call the package glibc.
I hope you can find what you are missing!

You could also use nix to install blugon, but that really shouldnt be necessary when you fix your dependencies.

Thank you very much for your answer!
I managed to get it working installing build-essential and using the release 1.11.4 (I had issues with the location of libraries X11R6 with the newest version).
But it's up and running now :)
Thanks for your help!
