Build and Run

Dependencies

The following software is required in order to build and use ELVE.

• Qt (5.7 or later)
• boost (1.60 or later)
• g++ (6.2.0 or later)
• libstdc++6 (for full c++11 support)

To download Qt, follow the instructions on Qt website.

In Ubuntu Qt and the other packages can be installed with the following commands.

sudo apt-get install build-essential git libboost-all-dev g++-6 libstdc++6
sudo apt-get install qt5-default qtcreator libqt5svg5-dev

Build

Building ELVE is straight forward:

mkdir build
cd build
qmake CONFIG+=release ..
make

Install

sudo make install

Will install ELVE for the current user, adding the ~/.elve folder to the $HOME directory.

If, for permissions reasons, ELVE could not be installed with sudo. It is still useful to run

make install

As this will create the folder in the $HOME directory and add a RunElve script to the build/Elve directory.

Run

Once installed, ELVE can be run this way:

Elve

or this way if the user could not install it with sudo:

#in build/Elve
./RunElve

Stdin control

ELVE terminal allows issuing commands. But often we would rather execute a whole script or have commands coming from another software.

Since the standard input is redirected automatically to the internal terminal, you can pipe your script files to Elve like this:

cat myelvescript | ./Elve

ELVE script files are simply either semi-colon separated or newline separated list of commands.

Sample script content:

load_blif "~/mul5.blif"
level_layout
show -g
cluster
select --add 1 338 154 150 340
group -m 1
select -c 1 365 359 244 351 252 185 199 353 347 358 195 357
extract -n

And of course, this also allows software to launch Elve frontend as a subprocess and invoke commands automatically through stdin.
