How to correctly reinstall version 2

[Anonymous]

Hello,

Until now I was gratefuly using mgl version 1 and today I installed version 2
on linux using the instructions:

cmake .
cmake .
make
make install

but then I realized that I forgot to enable-qt. I tried to make uninstall, in
order to reinstall the library, but with no success. Then I just did:

cmake enable-all .
cmake enable-all .
make
make install

The instalation finished, but there is no mgl/qt.h file. If I understand this
correctly, I am supposed to use mgl/qt.h instead of mgl/mgl_qt.h which is from
version 1. How can I make everything right again?

I am not familiar with linux very much. I use synaptic package manager to
install libraries, but I cannot find version 2 using synaptic package manager,
so I decided to install it on my own and now I messed it up :(

Please help. Any advice is appreciated.

Dear Martin,

Firstly, I recommend to use cmake-gui for setting non-standard option of
MathGL.

However, you can still use console mode as you wish, but please read cmake
manual (or at least 'man cmake'). In yours case you need to use something like
this

cmake -D enable-all=1 .

But possible you may require to setup paths for additional libraries too.

Thank you Alexey! I tried it again and this time it is correct. It was my
mistake, the header was "mgl2/qt.h" and not "mgl/qt.h"
