I notice that, when a value to be rounded is 5, LibreCAD rounds down, not up. For example, if the drawing precision is 0.00 and an entity such as a straight line is 30.165, when dimensioning the line, LibreCAD draws 30.16 instead of 30.17.
What is the standard drafting rule for rounding, up, down or other? What are LibreCAD's rules? Can the rounding rules be adjusted? |
Hi,
Thanks a lot for raising this issue: The current implementation always rounds down, and seems to be a bad choice to me. Please have a look at the source code: https://github.com/LibreCAD/LibreCAD/blob/master/librecad/src/lib/math/rs_math.cpp#L320

I tried building the source but it fails:

"Project ERROR: Unknown module(s) in QT: help"
http://askubuntu.com/questions/508503/whats-the-development-package-for-qt5-in-14-04 Maybe the second answer is what you need? qtbase5-dev Otherwise, the third answer shows: help qttools5-dev libqt5help5 |
qttools5-dev is what I think you need to install...
|
Thank you ravas for all your suggetions. I am at the office right now; I will try your suggestions when I get home later today.

Thanks ravas. I installed qttools5-dev and got past that error. Unfortunately, there are yet more errors, this time related to printing, perhaps.

Looks like a problem I recently introduced.
It's fixed now if you know how to sync your local repository. Otherwise you could delete the code manually and rebuild. https://github.com/LibreCAD/LibreCAD/commit/0a4ca3caefa706135fb831b402a647c6485a0ea5 |
Why it was happening is not apparent to me...
It built fine for me and it clearly shows that those types are a part of QPrinter in Qt 5. http://doc.qt.io/qt-5/qprinter.html#PaperSize-enum |

What version of Qt are you using specifically?
|
In reply to this post by ravas
It looks like there are two other places to find this enum
enum QPagedPaintDevice::PageSize enum QPageSize::PageSizeId Since QPageSize was added in 5.3 it would probably be safe to use #if QT_VERSION >= 0x050300 I'm going to wait for some feedback on the Qt forum. |

Thanks! It looks like my guess about 5.3+ was probably right.
However, with the fix I mentioned, I would expect that you can build now. |

I just deleted the directory and re-cloned the repo to ensure I got a completely clean start. It seems to build but I still get what appears to be an error. The error message appears around line 966 of 1390 lines of make output complaining something about not finding a Boost installation, which I think I have. My question, is it really an issue or am I good to go?

I previously installed LibreCAD using apt-get install. Should I uninstall that first? |
As far as I understand it, on unix boost is looked for via this code in boost.pri:
BOOST_DIR = $$findBoostDirIn( /usr /usr/local /usr/pkg /opt/local ) Therefore if it is not in one of those locations it will fail. Boost is required. Something else I'm noticing is you have some qt4 and some qt5 libs. And I think that is part of the problem. In https://github.com/LibreCAD/LibreCAD/blob/master/scripts/postprocess-unix.sh I notice [ "$( which lrelease-qt4 )" ] && LRELEASE="lrelease-qt4" Maybe this needs to be updated? This is out of my realm of experience. You might have more luck if you focus on qt4... unfortunately. From https://github.com/LibreCAD/LibreCAD/wiki/Build-from-source Good luck! >_< |
I uninstalled qt4 and qt5 and reinstalled qt4 ($ sudo apt-get build-dep librecad) but I have unresolved dependencies. Here is the output of apt-get:

Hey folks,
I found a solution to my last post after hours of agonizing googling! $ sudo dpkg --force-all --purge libqtcore4 $ sudo apt-get install libqtcore4 Now, apt-get update and upgrade do not give errors. I'm not sure what happened to my config files but it seems to be fixed now. I will now try building the source. Stay tuned! Allan |
