Mm, normally you should use the mingw env in msys2, from your prompt it
appears you use the msys env.

Normally I would expect all psths it uses for binsries to be unic like,
that is /c instead of c:/

Thanks for the info. Good to know that libocct is the library I will need to 
install when the switch is made from OCE to OCC.

Re: [Kicad-developers] How many users does KiCAD have?

[Seth Hillbrand]

Hello Avishay-

We do not currently have telemetry for KiCad directly.  But we do have some
metrics on downloads as a proxy for installations.

We average ~1500 downloads per day from the KiCad website.  This is
relatively steady over time and works out to 225,000 downloads of KiCad
5.1.9.  This accounts for Windows (90%) and MacOS (10%) but does not
account for installations on linux and other *nixes.  From the Ubuntu
numbers given by Jean-Samuel, Ubuntu will account for another 30 downloads
per day or a total of 5k users.

The limitations of this method of counting:
1) It does not track _unique_ download (no IP logging), so a user
downloading twice will count twice
2) It does not account for users that neglect to upgrade their minor
versions, so it does not count users of 5.1.0-5.1.8 that have not upgraded.
3) It does not count Linux users who compile on their own or install
versions directly from their package managers (and not the Ubuntu PPA)

Overall, this is likely our baseline number.  We don't have estimates for
the rates of upgrades, so we can't say how much larger the true number is
right now.  It also does not capture users running nightly builds (they are
more likely to download multiple times for the same installation) or users
running older versions of KiCad.

Also of interest might be this breakdown of the locations of users
downloading KiCad:
[image: image.png]

As you can see, we are dominated by European users at the moment.  I will
note that both Asia and South America are becoming more prevalent.  And, in
case this graph concerns people, it is derived by major IP octets.  We do
not store IP addresses, but we do store coarse locations by zeroing out the
lower two octets of IP addresses before geolocating to a country.  This
helps us to make informed decisions about features (e.g. ISO vs. ANSI vs
JIS vs GOST?) to include in future versions of KiCad.

While we do have some ideas of commercial usage, these are not data that we
share publicly.  I hope you understand.

I hope this helps.

Regards-
Seth

Re: [Kicad-developers] OCE vs. OCC default build flag

[Ian McInerney]

I would prefer we keep this change to 5.99/6.0 only and not force a default
change in 5.1 builds. There are enough other dependency changes going on
for future v6 that packagers/users have to handle I think it is more
reasonable to force it there.

Re: [Kicad-developers] SPICE_VALUE behavior

[Wayne Stambaugh]

Hi Sylwester,

I don't know that we need to support SI units in spice strings but I 
suppose it wouldn't hurt.  That would have to wait until V7 as it is a 
new feature.  The test cases look correct so I don't see any issues here.

be an overkill. The easiest solution is to ignore everything after 
number and prefix.


See below the testcases I made on AC tab of Simulation Settings dialog:

you will need to have installed libocct-data-exchange-dev which will
probably pull in other OCC related packages as an dependency.

Re: [Kicad-developers] OCE vs. OCC default build flag

Make sure that OCE is not installed along side OCC.  I also had to add 
"-DOCC_INCLUDE_DIR=/${MINGW_PREFIX}/include/opencascade" so that 
FindOpenCASCADE.cmake could find the header files.  Everything else 
should build as normal.

I think that we should remove OCE altogether.  The existing versions 
have bugs that we cannot fix and it is fully deprecated at the source 
repository (https://github.com/tpaviot/oce/releases 
) in that it only tags upstream 
releases and hasn't released any updates since 2018.


Keeping OCE in the build tree as an option is just asking for headaches 
that we can avoid in v6.

I understand it's a tricky question to answer, especially when it comes to
open source software, but is there any estimation about the number of
active KiCAD users? How many (commercial) companies use KiCAD? How many
people downloaded each version of KiCAD?
