Error while loading the Code Generator toolbox in Scilab - scilab

I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.

I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.

I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")
Scanning repository http://atoms.scilab.org/6.0 ... Done
ans =

The help systems return "help provider not available"

I'm using visual studio code to program in R and I have recently had trouble using the ?func and ??func command.
When typing something like ?rnorm, the message Couldn't show help for path: /library/stats/html/Normal.html shows up. The path is there and I'm sure R is in the path environment. This is really boggling me.
When I first installed R it was working absolutely fine in VSC but now it does not work. However the function works in the R shell. When I try to navigate to the R extension and click on "Help Topics by Package" it says help provider not available.
The packages/html files are there, but VSC doesn't want to access them.
Please advise what I can do to solve this.
I solved the same issue by checking my environmental variables. The steps I followed:
I added the bin installation file (C:\R\R-4.1.3\bin in my case, or C:\Program Files\R\R-4.1.3\bin) to the path in my user environmental variables. If you have an admin account, then you have to add the bin folder to the system environmental variables.
Check if you can start a R console from any terminal.
If that is positive, then in the Rpath settings for the R extension in vscode write r, or in the settings.json: "r.rpath.windows":"r"
Restart vscode. Check if the help pages are working.
Hope this helps ! Cheers.
This happened to me as well. I googled and tried different things and this works for me:
You need to provide the Rpath for the system you are using in the settings for the vscode R package. For example, for a windows machine, you need C:\Program Files\R\R-4.1.3\bin\x64\R.exe there if you installed the latest R using the default settings, and similarly for other systems.
Hope it helps!

Building Tools are missing in RStudio

First of all, I am working on a Mac. I am trying to install Blotter from GitHub. I found several descriptions of how to do that but my RStudio tells me that I am missing Building tools and gives me a link (https://www.cnet.com/how-to/install-command-line-developer-tools-in-os-x/) where it is described to do that. So far so good. I downloaded Xcode and the command line tools for Mac and installed those. Nothing changed even after restarting R. Then I found this https://cran.r-project.org/bin/macosx/tools/. I installed it and during that, it told me that I had to do the following
"This package will install clang 6.0.0 for OS X 10.11 (El Capitan) or higher with OpenMP support in /usr/local/clang6
In order to use this compiler you have to add /usr/local/clang6/bin to the PATH environment variable such as
export PATH=/usr/local/clang6/bin:$PATH"
So I changed the environmental variable path as follows http://blog.tonytsai.name/blog/2018-05-07-setting-path-variable-for-gs-command-in-rstudio/.
How I changed the PATH variable.
Again I restarted R but still, nothing changed. I still get the notice that the building tool is missing.
Somehow it seems to me that I installed everything correctly but R doesn't recognize the Programmes. Does anyone have an idea? I tried to search for settings to tell R that I installed the command line tool but couldn't really find anything helpful.
Ok, a bit of an update.
Best I can see it that Blotter is built and stored on R-Forge packages under a package called RStrategist
In R console type/cut & paste this.
install.packages('RStrategist',repos='http://R-Forge.r-project.org')
See R forR-Forge for more details. Once this has been installed run instead.
library(RStrategist)
Unfortunately, I am not willing to install this package and see if it works mainly because 1) don't need it nor know how to use it, 2) not sure how good packages are from R-forge, though it seems legit, but, this brings me back to point one.
So before i read the updated answer of Conrad Thiele i was trying around bit. Basically i deleted R, R Studio, Xcode and Command Line tools. Then i installed Xcode, Command Line tools, R and RStudio. Then i followed the notice on https://cran.r-project.org about the tools and installed both stated tools. As mentioned in the original question the Clang package tells you to change the Environmental Variable. And there was the mistake i believe. I originally simply pasted "PATH=/usr/local/clang6/bin:$PATH" into the the ".Renviron" file. With reading up online i noticed that "export PATH=/usr/local/clang6/bin:$PATH" is actually a Command for the Mac Terminal. After executing it, it sill didn't work but then i remembered that i still had the Path "PATH=/usr/local/clang6/bin:$PATH" in the the ".Renviron" file. Once i deleted that it worked. So i guess the key was that with changing the Environmental Variable correctly R found the connection with the right tool. Patients paid off.

Why can't I run TexMaker?

Background
Currently workingh on an Arch Linux and I want to modify and edit tex documents. I though texmaker would be the best available tool for this.
Problem
It seems to have installed perfectly, but I get the error below whenever I try to run texmaker from the terminal. If I double click to the shortcut, I don't even get an error.
texmaker: /usr/lib/libQt5Core.so.5: version `Qt_5.8' not found
(required by /usr/lib/libQt5Sensors.so.5)
texmaker:/usr/lib/libQt5Core.so.5: version `Qt_5.8' not found
(required by /usr/lib/libQt5Positioning.so.5)
texmaker: /usr/lib/libQt5Core.so.5: version `Qt_5.8' not found
(required by /usr/lib/libQt5WebChannel.so.5)
Is this related to ROS that I have installed on my system?
Did a simple yaourt -Syu and now it works!

How do I get Rtools 3.0 working for R 3.0? R can't find the installation

I'm trying to get R to recognize that I have installed Rtools.exe. I've tried installing it in several different locations. However, whenever I restart R and load devtools I get the same error:
> library(devtools)
WARNING: Rtools is required to build R packages, but is not currently installed.
Please download and install Rtools 3.0 from http://cran.r-project.org/bin/windows
/Rtools/ and then run find_rtools().
Naturally, whenever I try the function find_rtools() I get the same error message. I'm done trying to figure this out with help files, as the devtools help doesn't offer much. I've tried installing in several of the locations returned by get_path() but the problem persists.
FYI, currently my R is installed at D:/R.
Has anyone else had this problem, and more importantly, can anyone help me?
I'm sorry if this is a duplicate, and I've tried to include as many relevant details as possible so if you need any clarification please let me know.
Thanks,
Nick
Grab the batch file Rpathset.bat from batchfiles, edit the SET statements in it appropriately and then run R like this from the Windows console:
Rpathset
Rgui
I ran into this issue running a Windows 7 machine without admin rights. I leveraged G. Grothendieck's response, with a few additional steps.
Get Rpathset.bat from https://code.google.com/p/batchfiles/
Edit the Set statements in Rpathset.bat to your paths
Run CMD and change directories to where Rpathset.bat is stored
In the command prompt, run rpathset.bat > mypath.txt
Open mypath.txt with a text editor
Click Windows Start and search for environment
Click Edit environment variables for your account
Click path and then edit
Copy and paste the entire path from mypath.txt into the Windows path (everything after the path statement)
Restart RStudio and check that devtools::find_rtools() is TRUE
This file rtools.r contains the code for find_rtools(). It looks like it is trying to find ls and gcc in your system path (and then does some more checks based on the version) and if that fails it tries to look up SOFTWARE\R-core\Rtools in the the Windows registry.
As Thomas mentioned here, "Rtools is not a package." This is what I did to install Rtools. My RStudio is running R version 3.1.3. So I downloaded Rtools31.exe from https://cran.r-project.org/bin/windows/Rtools/. I executed the exe file, selected all the default options in the Setup Wizard and installed. (I had admin privilege on the computer I was using but I am not sure if that makes any difference.) To check that it was properly installed, you can enter find_rtools() in the R prompt which should return TRUE if Rtools installed properly.
For R 3.0, you probably just need to download Rtools30.exe and follow the same steps above.
I ran into this problem trying to install Rtools33 to use Hadley Wickham's lineprof package. I got that error multiple times. I'm running Windows 7 on a laptop.
I was able to fix the problem by running the Rtools installation file as the windows Admin (i.e. right-click the Rtools33.exe and choose "Run as administrator")
I also made sure to point the path to the R source directory, which I kept in C:\Rtools\ (which contains C:\Rtools\bin\ and C:\Rtools\gcc-4.6.3\).
This solved the problem for me and I am now able to install lineprof from GitHub and make use of it.

dart_api.h not found when build library dart_sqlite

As i ask before, to use dart-sqlite, I must install dart-ext:sqlite first. But every time I try to build it, I found error= Can not found dart_api.h. how to fix it?
I install it on ubuntu 12.04.
Thank you
It sounds like you didn't follow the build instructions:
Either edit build.sh to point to the SDK, or set the environment variable DART_SDK.
Once you correctly point DART_SDK to the dart-sdk directory of your local Dart installation, the build system will find $DART_SDK/include/dart_api.h just fine.
