newsFirst go using SolveSpace
I posted about SolveSpace:
https://bkhome.org/news/201911/using-solvespace-v23-in-pyro.html
After working through a couple of tutorials, had a bit of a go at
drawing a basin-type distiller. Hmmm, got to the point where some things
became difficult. This is as far as I got, exported as PNG:
I could plough ahead, however, there really isn't much point. I can
create reasonable drawings with pen and paper, no need for the fancy 3D
visualising. Even a 2D CAD program would be OK, to publish drawings that
are more tidy than my hand-drawn sketches.

Using SolveSpace v2.3 in Pyro
Yesterday I posted about including SolveSpace v2.3 in the next
build of Easy Buster, and v3.0alpha (latest from github) in Easy Pyro:
https://bkhome.org/news/201911/solvespace-parametric-3d-cad-in-easyos.html
The latest source looks good, more features, however, last night I was working through this tutorial, running Easy Pyro:
http://solvespace.com/bracket.pl
Those tutorials are excellent, but they are written for v2.3 and I
discovered slight UI differences -- only slight, not a show-stopper.
Zoom in-out does not work in v3.0alpha (but later I found that it
doesn't work in v2.3 either).
What did stop me was when I tried to open my creation in v2.3, that had been created in v3.0alpha -- which hung the application.
I can live with less features, for now want the compatibility, to be
able to open and edit drawings created in either Easy Pyro or Buster.
And then there's the tutorials being written for v2.3.
Oh, yes, v2.3 uses gtkmm v2, which is already in Easy Pyro. gtkmm v3
is a very big package. So including v2.3 in the next release of Pyro
will hardly add anything to the download size.
Compile notes for v2.3 in Pyro 1.2.8:
requires json-c, gtkmm v2, unifont
# patch -p1 < ../debian/patches/01_RemoveGitHash.patch
# patch -p1 < ../debian/patches/20_use_system_unifont.patch
# patch -p1 < ../debian/patches/30_fix_ftbfs_glibc.patch
# mkdir build
# cd build
# cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr
# make
# new2dir make install
The PET has been uploaded, as well as a 'unifont' PET, so in the
"petget" package manager, update the package database. If you already
installed v3.0-alpha, uninstall it first.
Got to say, liking SolveSpace!
EDIT:
Oh bother! v2.3 is hanging in Easy Pyro. Have to use the v3.0alpha. Both
are in the package manager. If you have already installed v2.3,
uninstall it, and instead install package 'solvespace3'.

SolveSpace parametric 3D CAD in EasyOS
SolveSpace is another CAD application. See links to QCAD and FreeCAD here:
https://bkhome.org/news/201911/qcad-2d-cad-application-compiled.html
Example construction in SolveSpace;
SolveSpace has various points in it's favour: looks easy to use (from
a very superficial first-look), reasonably powerful, and small size. It
uses the gtkmm library, and is in the Debian DEB repository.
The version in the Debian repository is a bit old, version 2.3,
released in 2016, and uses gtkmm v2, which is already in the Easy Buster
build. So great, I have added it to the package list and it will be in
the next release of Easy Buster.
Note, if you are running Easy Buster and want to try it now, via
"petget", there is also another package 'libslvs1' -- install that too.
It is actually part of SolveSpace, looks like it is optional, and I
don't know what it brings to the table, but might as well install it in
case it is something useful.
For easy Pyro, I have compiled it from source, and got the latest out of github:
https://github.com/solvespace/solvespace
A downside of this latest source is that it requires gtkmm v3.
However, as this project is very active, with lots of commits since
2016, I decided to compile the latest source. Compile notes:
needs json-c
https://github.com/json-c/json-c
# cd json-c-0.13.1-20180305
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=x86_64-pc-linux-gnu
# make
# new2dir make install
needs gtkmm-3.0>=3.18
https://ftp.gnome.org/pub/GNOME/sources/gtkmm/3.22/
gtkmm 3.22.3
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=x86_64-pc-linux-gnu --enable-static --enable-shared --disable-documentation --enable-x11-backend=yes --enable-wayland-backend=no
# make
# new2dir make install
# git clone https://github.com/solvespace/solvespace.git --depth 1
# cd solvespace
# git submodule update --init extlib/libdxfrw extlib/flatbuffers extlib/q3d
# cd ..
# mv solvespace solvespace-20190920
# dir2tgz solvespace-20190920
# cd solvespace-20190920
# mkdir build
# cd build
# cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr
# make
# new2dir make install
I have uploaded the PET packages, so via "petget" on the desktop, if
you update the PET database, you can install SolveSpace -- or, wait
until the next release of Easy Pyro -- yep, might as well be consistent
with Buster.
The thing for me to do now is learn how to use it, find out if it is suitable for my solar water still designing.
Here is the project home page:

On YouTube, there are tutorials, uploaded by Eric Buijs:

QCAD 2D CAD application compiled
I posted earlier about FreeCAD provided as an SFS:
https://bkhome.org/news/201911/freecad-sfs-created-for-easyos.html
I have been exploring other CAD applications. QCAD has been around
for a long time, and is very easy to use. It is only 2D, though does
have isometric views. There is a paid-for version, also a free
open-source GPL version.
I compiled the open-source version in Easy Pyro 1.2.8. Note, QCAD is
not available in the Debian repositories, however the SFS that I have
created will work in both Pyro and Buster.
It requires 'qtscript', so I had to compile that:
Downloaded from here:
https://download.qt.io/archive/qt/5.10/5.10.1/submodules/
# export OE_QMAKE_AR=ar
# qmake PREFIX='/usr' LIBDIR='/usr/lib' PKG_CONFIG='/usr/bin/pkg-config'
# make
# make install
...had to manually create the PETs.
Downloaded QCAD source from here:
https://github.com/qcad/qcad/releases
# export OE_QMAKE_AR=ar
# qmake -r PREFIX='/usr' LIBDIR='/usr/lib' PKG_CONFIG='/usr/bin/pkg-config'
...errors, but go ahead anyway...
# make release
# cd release
# LD_LIBRARY_PATH=. ./qcad-bin
Created a PET and a SFS. The SFS has been uploaded, and you can get
it by clicking on "sfsget" on the desktop. It will work in both Pyro and
Buster, in the latter case in a container only.
Here is the QCAD home page:
If you go to YouTube, there are tutorials.

FreeCAD SFS created for EasyOS
I have been making very rough sketches of the solar water
distiller prototypes, and have even published some of them to this blog.
Planning for basin-type prototype #2, thought might have a go at better
quality drawings.
Running Easy Buster 2.1.8, I installed FreeCAD from the Debian DEB
repository, via the "petget" icon on the desktop. This has a massive
number of dependencies. After installation, ran it, and it did start,
but with an error message:
No module named StartGui
A google revealed this to be a known problem in Debian, that was fixed by running:
# update-alternatives --all
Now it works, well, starts anyway, and beyond that I haven't got a
clue. However, there are lots of tutorials, including YouTube videos.
I made it into a SFS, a massive 239MB, and tested that it works in Easy Pyro 1.2.8 in a container.
If anyone reading this knows how to use FreeCAD, you are welcome to
test it, and let me known if there are any issues. You just need to
click "sfsget" on the desktop, and can download and install to either
Buster or Pyro -- in the latter case, as a container only.

Easy Pyro 1.2.8 and Buster 2.1.8 released
EasyOS versions 1.2.7 and 2.1.8 were released about two weeks ago:
https://bkhome.org/news/201910/easy-pyro-127-and-buster-217-released.html
Enough new things have happened to warrant new releases. The
so-called EOL (End Of Line) Pyro series is continuing to receive version
bumps, and if you read the release notes you will see that the version
bump 1.2.7 to 1.2.8 and 2.1.7 to 2.1.8 are both getting the same
changes.

Extra notes
One thing that I forgot to post about, several days ago I created a
SFS of Firefox. This was created from the Debian 10.1 DEB repository,
Firefox version 60.8.0 ESR (long term supported version, with current
security patches). So, although an older version, it is kept up to date
for secure browsing.
Having Firefox as an SFS has many advantages, one being that you can
download it and install as a container, for super security. Or, you can
if you wish install to the main desktop. Just click "sfsget" on the
desktop.
If you don't know anything about SFS files and Easy Containers, please read up on it. There are some usage notes here:
https://easyos.org/user/using-easy-containers.html
...as that page explains, even though the Firefox SFS is for Buster,
you can install it in Easy Pyro. So, I didn't have to create a separate
SFS just for Pyro.

pSynclient setup for touchpad
This is great news. For forever, we have used flsynclient, a
compiled utility that uses the fltk library. There have been problems
with this, such as the latest official version unable to load pre-set
settings at startup. Also it is a dead project.
Forum member 'mistfire' has come to the rescue with a 'pSynclient' written in bash and using gtkdialog, see forum post:
http://murga-linux.com/puppy/viewtopic.php?t=117240
I have created a PET of version 1.3, which I modified slightly. Took
out the "XDG" button, also some widgets were rendering overlapped. Named
it version 1.3-1:
