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!

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I'm not sure why you are using an outdated version of Scilab.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")

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.
I'm re-running some R Markdown scripts that worked fine a month ago, but now kable_as_image is unable to find Ghostscript (yes, I'm on Windows 8). I get the following error message:
Error in kable_as_image(criteria.table,"Criteria",file_format="jpeg"):
Ghostscript is required to read PDF on windows. Please download it here: https://ghostscript.com/
My computer still has Ghostscript, which runs fine when I open it up independently (I tried reinstalling Ghostscript; it didn't help). My guess is that the problem has something to do with R, RStudio, or a package being unable to find the Ghostscript.
I'm pretty sure I've upgraded R in the interim, and I'm currently on 3.4.3 with the latest versions of kableExtra and magick. I've also tried
Sys.setenv(R_GSCMD="C:/Program Files/gs/gs9.22/bin/gswin64.exe")
(and also for gswin64c.exe) but that didn't help, either. Any advice would be appreciated.
Despite what the error message says, R needs the path to MikTeX (or your TeX program of choice), not to Ghostscript itself. The best solution is to add it to PATH in your operating system directly so it's always there, but it also works to add it within R. This is helpful to test it out before digging into your OS (make sure you have the right path), or if you don't have administrator privileges to your work machine.
Sys.setenv("PATH"=sprintf("%s;C:\\Users\\me\\AppData\\Local\\Programs\\MiKTeX 2.9\\miktex\\bin\\x64\\",Sys.getenv("PATH")))
Your path to MikTeX will likely be different than mine. Note that you need sprintf() or something similar to add the directory to the end of the PATH instead of overwriting the existing path.
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.
I just updated R from version 2.15.1 to version 3.0.0 on my MAC running 10.6.8 and now R crashes on startup.
I get the error:
Error in getLoadedDLLs() : there is no .Internal function 'getLoadedDLLs'
Error in checkConflicts(value) :
".isMethodsDispatchOn" is not a BUILTIN function
Any ideas on how to go about?
The most common cause of this is having a corrupted ".Rdata" file in your working directory. Using the Mac Finder.app you will not by default be able to see files that begin with a ".", so-called dotfiles. Those files can be "seen" if you execute a change to the plist controlling the behavior of Finder.app. Open a Terminal.app window and run this bit of code:
defaults write com.apple.Finder AppleShowAllFiles YES
Then /point/-/click/-/hold/ on Dock-Finder-icon, and choose "Relaunch"
If you to do so, you can then change it back with the obvious modfication to that procedure. I happen to like seeing the hidden files so that's the way I run my Mac all the time, but some people may feel it is too dangerous to expose the "hidden secrets" to their own bumbling.
Paul raises a good point: I run the following R function in the R console after updating:
update.packages(checkBuilt=TRUE, ask=FALSE)
I have a lot of installed packages and paging through the entire list has gotten too tiresome so I bypass the ask-messages. Sometimes you will get errors because there may be dependencies on r-forge or Omegahat packages or on packages that need to be compiled from source. These may need to be updated "by hand". And you may need more than one pass through such an effort. Take notes of which packages are missing and fill them in.
I had the same problem running RKWard on ubuntu 12.04.
Check your r-base-core, like Paul suggested, to make sure the version is also at the latest version. Mine didn't update automatically. I had a platform dependent version, but RKWard was calling the new version. To solve this problem, I simply marked r-base-core for removal and reinstalled the latest version or r-base-core. poof problem fixed, bippity boppity boo!
I suspect that your error is similar to mine because I had also JUST updated RKWard. Start at updating r-base-core or try to get all of the dependencies to match up the versions.
I hope that you can translate this into what to do on a MAC,
SU
