libqt4-help qt4-dev-tools libboost-all-dev libmuparser-dev

Compilation steps:

1. First download this


2. Extract this

3. Go to this directory

    $ cd LibreCAD-dwgsupp2

4. Disable test build (only used in libdxfrw develop).
    To disable comment line #7 in tests/libraries/libraries.pro (#        libdxfrwtest \)

5. Build makefile

    $ qmake librecad.pro

6. Compile

    $ make

Running steps:

1. Made DWG file in CAD software like circle.dwg.
You can download from this.

2. Go to this directory

    $ cd unix/

3. Run this

    $ ./librecad circle.dwg

4. If nothing shows, then click on Auto Zoom.

It shows following output:
