# [2019.12.19] Building From Source

During this year, I mostly used a desktop not connected to the
Internet at work. Since I don't use a corporate MacBook anymore, I
have a corporate desktop with the Internet connection. And although
some sites are banned or work improperly because of the
man-in-the-middle, it's still possible to build software from source.
I was a bit surprised that it's possible even without being `root`.
One only need to use some subdirectory of `HOME`, e.g. `.local`,
include it in variables `LD_LIBRARY_PATH`, `LD_RUN_PATH`,
`PKG_CONFIG_PATH`, and `MANPATH`, and run `make` with `--prefix`
option. For some hard cases, I needed to set `LDFLAGS` and
`CPPFLAGS`, too. And sometimes before running `configure`, I had to
run `libtoolize` or `autoreconf`. Still, I was easy, I now I have not
only Emacs but also `screen`, `xclip`, `curl`, `wget`, and most
important --- Python of any version built by `PyEnv`. There are so
many things to be sad about at work, but building open-source for a
comfortable environment makes me happier.
