Run multiple process?

[duccoder]

At one point, I can only open a single window GUI or run only one script.
If I run the 2nd will receive the message "Warning: Application already running. Aborting ..."

Is there any way I can run multiple process

- Open multiple windows simultaneously
- Run multiple scripts
- Just open the window that run scripts

From the output of ./qcad -h:

Usage: qcad [Options] [Files to open]

...
-allow-multiple-instances        Don't try to avoid multiple instances from running
                                 simultaneously.
...

Thank. I try:

$HOME/opt/qcad-3.9.4-linux-x86_64/qcad -allow-multiple-instances
$HOME/opt/qcad-3.9.4-linux-x86_64/qcad
$HOME/opt/qcad-3.9.4-linux-x86_64/qcad

Then 3rd will abort

So, need pass -allow-multiple-instances every command run?

Starting QCAD without -allow-multiple-instances checks for other running instances.
Starting QCAD with -allow-multiple-instances does not check for other running instances.

Note that if you are using the library browser, -allow-multiple-instances might break your library data base. This parameter is mostly useful for command line tools (which don't use the part library browser). For example the dwg2bmp, dwg2pdf, dwg2svg conversion scripts.
