On my Ubuntu 16.04 I'm trying to build freetype-2.8 and libgd-2.2.4.
Here is how I build freetype2:
./configure \
--prefix=/home/stephane/programs/install \
--with-bzip2
make
make install
make clean
Here is how I build libgd:
./configure \
--prefix=/home/stephane/programs/install \
--with-jpeg=/home/stephane/programs/install \
--with-png=/home/stephane/programs/install \
--with-freetype=/home/stephane/programs/install \
--with-zlib=/home/stephane/programs/install \
--with-xpm
The configure command reports it finds freetype2:
Support for Freetype 2.x library: yes
But the make fails with the error:
gdft.c:154:22: fatal error: ft2build.h: No such file or directory
I can see freetype2 was installed in the following directories:

How to have freetype2 install its header files in the expected include directory ?
Note: I know I could install a package using sudo apt-get install -y libfreetype6-dev but this is not what I want. I want to build it myself.
I upgraded the release of GD to libgd-2.2.5 but the exact same error keeps occurring.
By using the 2.7.1 version of freetype I can build GD just fine.
There is something that changed in freetype from freetype-2.7.1 to freetype-2.8.* that breaks the build of libgd-2.2.4 or libgd-2.2.5.

I downloaded scala,unpacked it and copied to /usr/local/share
After that,I edited ~/.bashrc
export SCALA_HOME=/usr/local/share/scala-2.12.8
export PATH=$PATH:$SCALA_HOME/bin
Anyway,it does not work.
scala -version
Command 'scala' not found, but can be installed with:
sudo apt install scala
I could go for apt install but I don't get it what is wrong.

Editing .bashrc won't affect an already open shell. You could explicitly source it (source ~/.bashrc) to have it take effect, or open a new shell to reload it.
I am doing Chapter 1 exercises from Linux Basics for Hackers (Starch Press):
Create a new directory called hackerdirectory and create a new file in
that directory named hackedfile. Now copy that file to your /root
directory and then rename it secretfile.
So I did mkdir hackerdirectory then cd hackerdirectory then touch hackedfile then sudo mv hackedfile /root
My understanding is that /root is the top home directory but when I cd .. back to home and ls -l, it's not there:

Edit (when sudo su)
root#nobu-ThinkPad-T420:/home/nobu# whereis hackedfile
hackedfile:
So when I do command whereis, it shows the file. So is it really deleted?
But now when I try: sudo find /root -type f -name hackedfile I get:
nobu#nobu-ThinkPad-T420:~$ sudo find /root -type f -name hackedfile
nobu#nobu-ThinkPad-T420:~$
And thus it seems to be gone except doing `whereis' still shows it with the colon.
Edit:
Beware that whereis returns whatever you were looking for say filename: and then lists the PATH of location after colon.
So here is how to use find:
find
That's from my textbook listed above.
Try pwd to see where you are in the file system. You will probably find the file using sudo ls -al /root
In ubuntu 16.04 I have in bashrc:
alias python=python3.6
In other words, the command python starts python 3.6.
Now I want a virtualenv with python 2.7.
I have installed virtualenv:
virtualenv -p python2 pgadmin4
Then activated it.
Now check:
$ which python

Well, just writing python must run python2.
But:
$ python
Python 3.6.2 (default, Jul 20 2017, 08:43:29)
Could you give me a kick here?
When you activate a virtualenv, under the hood, the PATH environment variable is rewritten to give more priority to the bin directory of your virtualenv.
The which python command tells you the path you expect because it ignores any alias eventually configured. It looks at the PATH environment variable and tries to resolve the current python path.
Bash, instead, takes into account all the alias configured and when you types python, bash resolves the command to python3.6 which is not in you virtualenv bin directory and goes to the system one.
The only possible solutions are:
remove the alias
add a symlink python3.6 -> python inside the bin folder of your virtualenv

It is suggested that the recommended way to install this feature is using MELPA. I can clone this git repo, but I can not ping MELPA. My question is how can I manually install this Emacs feature? More generic, how can I manually install such a Emacs feature which is using cask?
In your example,you dose not need cask
git clone https://github.com/bbatsov/projectile /some/place/you/want
Then add
(add-to-load-path "/some/place/you/want")
in your .emacs or init.el.Then
(require 'projectile)
manually.
I have to include the pandas library in my package to run my software on a cluster server without pandas library installed but with all the right dependencies.
I tried to build on my pc the pandas library from source (ver. 0.8.1):
python setup.py build_ext --inplace
and if I move the builded pandas folder anywhere in some other folder in my pc I can import it in my software (ex ./mySoftwareFolder/pandas)
But when I move my software with pandas libray on the cluster server it raise me the error:
File "testPandas.py", line 9, in <module>
import pandas
File "/home/TEST/pandas/__init__.py", line 15, in <module>
raise ImportError('C extensions not built: if you installed already '
ImportError: C extensions not built: if you installed already verify that you are not importing from the source directory
like if it is not compiled.
What is wrong in my way to include library?
thanks a lot!
update:
the directory that I copy to cluster server contains:
-bash-4.2$ ll -a pandas
