There is a package CefSharp.OffScreen.NETCore
There is an example of its use under Windows
In theory, the package CefSharp.OffScreen.NETCore should be different from CefSharp.OffScreen cross-platform, that is, the ability to work under Linux. But judging by the example code of its use, it still depends on Windows.
Can this package CefSharp.OffScreen.NETCore work under Linux?
If it can, where can I see an example of its use under Linux?
CefSharp is built with Visual C++ which only runs on Windows.

According to its developer, the Cuba library (for numerical integration) will not run(?) on a Windows machine since the OS is missing the function fork(2).
Windows users: Cuba 3 and up uses fork(2) to parallelize the execution threads. This POSIX function is not part of the Windows API, however, and is furthermore used in an essential way such that it cannot be worked around simply with CreateProcess etc. The only feasible emulation seems to be available through Cygwin.
See [http://www.feynarts.de/cuba/][1].
Since Cuba.jl is just a wrapper for the Cuba library, does this mean that Windows users must install Cygwin in order to use this Julia package?
You don't have to install Cygwin to use Cuba.jl, a normal Windows system is sufficient. The package is tested on AppVeyor without any problem
I'm using QSysInfo to get OS information like the kernel version and OS name, but would also like to get the desktop environment (for example LXDE, XFCE, Luna, Aero, Aqua). Is there any way that I can do this (at runtime)? Grateful for help!
EDIT: I am looking for a cross-platform solution
I recently discovered a portable version of R and RStudio #
http://rportable.sourceforge.net/
Open source rocks!
At any-rate, I am jumping from pc to pc at my university, and I'd like to get Portable R-studio to recognize Portable R as the default R version. Most computers at the university already have several versions of r-installed, and RStudio uses one of those versions of R. When I go into the Global Options to change the default version, it does not "see" portable R on the USB drive.
I am basically hopping I can run R without constantly having to download packages, specifying the work directory, downloading Scripts, data from Google Drive, etc...
Any suggestions? I am open. Thanks for your help.
I did not need to touch the registry.
I first installed R portable and then R Studio portable, both from Sourceforge.
After launching R Studio for the first time, I was shown the option of choosing the installation of R to be used, as shown in
https://support.rstudio.com/hc/en-us/articles/200486138-Using-Different-Versions-of-R
I browsed to branch \PortableApps\R-Portable\App\R-Portable\bin, where executables are located. There I selected the 64-bit version.
If you want to change later the version used, you open R Studio and go to Tools -> Option -> General -> R Version.
This avoids modifying the registry, with the two advantages of Portable Apps:
Leaving no trace of the app in the system (or, at least, a much milder one).
Being really portable (or, at least, much more so).
On Windows, RStudio uses the system registry to find where installed versions of R are located. You'll need to edit the registry yourself to let it know about new versions. Fortunately you can do this in HKEY_CURRENT_USER so admin rights shouldn't be required. Here are the keys and values you'll want to write:

More detail about how RStudio selects the R version to run here:
https://support.rstudio.com/hc/en-us/articles/200486138-Using-Different-Versions-of-R
The link to R Portable above is a bit misleading. In order to run a portable version of R AND RStudio, you also need the 27MB portable RStudio here. What's even more confusing is that it has the same name as the RPortable file.
It took me a bit of time to figure that one out. Perhaps you could edit your question to point to both for those who wish for an IDE?
And, IMHO, it's not truly portable, because when you move from one machine to another you need to specify the R version on your USB drive and also the work directory. Pity.
I manage to link RStudio (not portable version) to the aforementioned version of R Portable, directly through Global Options -> R Version -> Choose a specific version of R -> Browse,
and the trick was selecting the R-Portable\App\R-Portable folder. Choosing another one doesnt allow RStudio to find the instalation.
Im running RStudio 1.1.463.
Bye!
I am developing an R package that relies on some Fortran subroutines. I write my code under Linux, but to be able to collaborate with my colleagues who work with Windows, I would like to be able to compile a Windows version of my package.
How to compile an R package for Windows under Linux? I have been looking into this issue on the web and found many suggestions and possible solutions, but no clear advice on how to do this with recent versions of R. It looks like cross-compiling was supported in previous versions of R, but not anymore today.
I am able to compile my Fortran subroutine for Windows under Linux using MinGW, but I am not sure about the next steps to create a package that can be installed on Windows. Does anyone have experience with this?
Any help would be much appreciated, thank you!
I've been coding with Python and C++ and now need to work on building a gui for data visualization purposes. I work on Mac Snow Leopard (intel), python 3.1 using gcc 4.2.1 (from Xcode 3.1)
I wanted to first install Qt and then PyQt. And my goals are to be able to:
- quickly prototype GUI and the accompanied logic that drives the GUI using PyQt and python
- if I decided I need the speed, or if it's fairly easy to translate my GUI into C++ using the Qt tools, I have the options to translate my app into C++
- Be able to deploy my application onto Windows (both the python and c++ version of my app)
Give the goals above, what are the correct steps I should take and what issues i should be aware of when setting up Qt and PyQt. Which other deployment tools do I need?
From my readings so far, here's what I have:
download the Qt source for mac and configure it with
-platform macx-g++42 -arch x86_64 -no-framework
(i've read somewhere that
building as framework causes some
trouble in deployment and/or
debugging, can't find the article
anymore)
download latest SIP source and build
download latest PyQt and build from source (any special options I should pay attention to?)
For deployment, I've read that I would need to use py2exe/cx_freeze for windows, p2app for mac:
http://arstechnica.com/open-source/guides/2009/03/how-to-deploying-pyqt-applications-on-windows-and-mac-os-x.ars
but seems like what the article describe is deploying an app you build on windows on the windows platform and vice versa. How do you deploy to windows (is it even possible?) if you are writing your Qt app on a mac ?
Really appreciate the help
I'm guessing by deploying, you mean a compiled version to users that have no Python or Qt or anything.
I'm been trying py2app for a while now and never really worked out for me. You can try PyInstaller. It worked out pretty well for me since it's made to work with plugins like PyQt and PIL etc. I put up some instructions here
http://tech.xster.net/tips/deploy-pyqt-applications-on-mac-os-x-with-pyinstaller/
They don't really support cross-compilation though. Just recently, they made cross-compilation for windows binaries on linux possible. If you want to spend some time hacking it, it's probably possible. But probably easier just to get a windows machine and building a binary with it.
