distance point to point precision

ravas wrote

I'm interested in using this program for geometric construction / exploration.
What I need is for the 'distance point to point' tool to produce at least 8 numbers
to the right of the decimal point. Is this currently possible?
Also, is there a way to access this tool via the command line?

Thank you! :-]

Sigh... I think I need to compile boost or something?
Running bootstrap gives:

'cl' is not recognized as an internal or external command,
operable program or batch file.

Failed to build Boost.Build engine.

My research indicates I might need visual studio for cl.exe.
I think installing an 11gb program is above and beyond what I'm willing to do to get this compiled.
I'll wait for the next .exe release of LibreCad.

I already downloaded Qt (5.4) with the online installer... does it matter?
I downloaded boost 1_53 and updated custom.pro
I unchecked shadow build.
I could not find this in Qt 5.4:
"Select librecad as building target in Qt Creator (instead of tff2lff, which is another choice)"

With build configuration set to 'release',
I tried once with 'build project librecad' and once with 'build all'
with I think the same result each time:

is explained by the fact I never created that file ;-].

It's really a miracle it compiled the last time.
I just found out today I needed to:
press windows-key
type qt
open 'QT 5.4 for desktop'

instead of opening the command line normally.

The last time it worked only because I had used QT creator to build beforehand.
Considering that part failed with errors, I say it was a miracle... ;-]

no. Just to figure out how to compile it with libxml++, similar way to what we described for boost and muparser in:
