2.2.0-rc4 does not display text in file created by 2.1.3

I have several .dxf files that work fine with librecad 2.1.3. When I open them with 2.2.0-rc4 built from git sources, the text does not display.

Any ideas?

Tom Dean

Are you able to share one of these files ?

Here is one of the files.EncoderMount.dxf

presumably simply https://forum.librecad.org/only-empty-boxes-frames-are-shown-for-image-text-no-line-thickness-tp5706737.html

I saw the draft issue in my google searches.
Draft is not checked.
I do not see empty boxes for text.
I have set text size to large values and still no text.

Well, then supply more info about how you built, which OS, what shows Help->About window?
How do you start LibreCAD?
Possibly the fonts are not found.

I also believe this is some form of env or setting problem. But, I expect drawings to pass seamlessly from one version to the next.

I have the same problem on 3 machines, all Ubuntu.
It is either a missing font or a mucked-up font environment or something in the build.

In 2.2.0-rc4, the MText dialog, the Font drop down box is empty.
In 2.1.3, the MText dialog drop down box has many things.

I found the problem.

When I built librecad, I did it out of the source tree, in a build subdir.

Rebuilding in the source tree resolved the problem

cd CAD/LibreCAD
qmake -qt=5 -r
make -j `nproc`
./unix/librecad

I want to install librecad in /usr/local/bin. But, it needs resources, etc. Just copying librecad to /usr/local/bin does not work.

We have no installation routines for Linux. There are too many distributions using different locations for this stuff.
Placing resources to their preferred locations is what the distribution maintainer usually do.

The LibreCAD application on Linux search different places for the resources like fonts, libraries, plugins, translations.

What is your intention to build from source?
If you just want a newer version I recommend to use or AppImage distribution.
Some Red Hat based distributions started to switch over to 2.2.0 release candidates lately.
I don' t know when Debian and derivates will follow, but at least when we release 2.2.0 finally soon. Then you can use apt to install and automatic updates.

When your intention is to modify code it is best to use librecad from unix folder, as it contains everything it needs.

For the above said reasons, we also have no installation instructions for Linux.
If you anyway want to install your built version manually, you can have a look into CI/build-appimage.sh. Assume that appimage/ is the root folder, then you see folders created under /usr and which resources are copied to these locations.
