there's definitely something wrong with setting up my environment variables.
I had messed around with it when I was trying to do an android app.
now i'm trying to set up netbeans, but it won't build.
when I first tried to build, tool selection came out, and it had looked for cygwin bin files in D: instead of C:, so I manually browsed for each file.
i found g++ make etc. however, I couldn't find gfortran.exe.
now, a message says that it can't find shell, and asks me to install cygwin.
this is what i have in my path:
D:\DAC driver and stuff\;%JAVA_HOME%\bin;
D:\matlab\MATLAB\runtime\win64;
D:\matlab\MATLAB\bin;C:\cygwin64\bin
and yes, cygwin is in C:\cygwin64
this is a picture of everything i have in my environment variables:

edit: i think i deleted something from 'path'! should there be something infront of what i currently have??
%JAVA_HOME%\bin is no legit. Everything after it doesn't count, fix is in link.

This is a long post, sorry.
I have been trying to start a project, using Rust, but ran into a problem: it just does not work correctly on Linux in VSCode/Atom.
Wasted 3 days, searching online, trying different tutorials/videos - nothing worked + most of the material is from 2017. I have tried Matrix chat, but no one knew what to do. Git too has no solution as people keep suggesting very random things, like "change this variable in toml file to something else, and back again"
Git: https://github.com/rust-lang/rls-vscode/issues/513
I installed (and re-installed rust many times in the last 3 days), and it works just fine from the terminal, but not in the Editor.
Two Issues:
Editors don't see any crates, so you can't run your code from the editor.
Autocomplete does not work (only works on std, not on extra crates you add).
What I did (out of many other things):
install Rust (on Manjaro and Debian computers): curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Tried stable, beta, nightly (for racer)
Just did a clean install again:
stable installed - rustc 1.40.0 (73528e339 2019-12-16)
Rust is installed now. Great!
Installed Rust (rls) rust-lang.rust extension in VSCode (and rust in Atom)
Created a new project: cargo new test_proj and added new rand = "0.6" to [dependencies] and used cargo build. It did build rand
Added "rust-client.enableMultiProjectSetup": true to the settings file to avoid a warning: A Cargo.toml file must be at the root of the workspace in order to support all features. Alternatively set rust-client.enableMultiProjectSetup=true in settings. by Rust (rls)
I also install 'code runner' extension that I use with Python, C++, and Java, to run the code from within the editor.
So now I have just the main func and it runs just fine from the editor:
Now I add rand and it seems to work, and does SOME auto-completion...
But now it stops working:
OK, I will finish the code and try running it, And now we can't run it anymore as the crate is missing:
OK, let's try Ctrl + Shift + B and try cargo build:
For some odd reason, it is looking in /media/Work/Work/rust_code and not in /media/Work/Work/rust_code/test_proj/
One last thing: let's try running in the terminal:
So it does work just fine.
Sorry for the long post, but I have wasted 3 days now and it still can't get it up and running. Did anyone manage to set this up at all?
It has to be Atom or VSCode as I have all of the other languages/projects setup there + VSCode is listed on the official Rust website, so I presume it should work.
Basically, out of two editors (VSCode and Atom), that have Debugging capabilities, unlike Intellij Rust, both don't work for me and I just can't code in Rust as tools are literally broken/not mature enough for productive work. Please let me know if I am wrong and it is just a case of one little flag, that everyone forgets to mention, is missing in some config.
Short Version
Assuming I understand the issue correctly. Then the various build issues boil down to different ways you're trying to build the project, and attempting to do so in different directories.
TL;DR: The directory you have open in VSCode is the rust_code directory. Close it and instead open rust_code/test_proj. Now the Rust: cargo build (or Rust: cargo run) should work.
Long Version
Editors don't see any crates, so you can't run your code from the editor.
The Rust: cargo build task isn't working, because the directory you have open isn't a "Rust project" (Cargo package), it's a directory containing another directory, which is a Rust project.
Looking at your screenshot shows this, look at how the top line says rust_code/test_proj:
When you execute the task, Cargo is complaining that rust_code/Cargo.toml doesn't exist, which is true since it's located in rust_code/test_proj/Cargo.toml
If you look at the output of this screenshot, you can see that is the case:
Here you're executing cargo run manually. But the important difference is that you're inside the rust_code/test_proj directory.
Lastly simply executing rustc main.rs is failing since you aren't passing the arguments needed. So rustc doesn't know anything about your dependencies.
Try executing cargo build -v then you can see all the arguments that Cargo is passing to rustc.
Autocomplete does not work (only works on std, not on extra crates you add).
Try and open a directory that contains a Cargo.toml, then code completion should work for dependencies. If I don't, then I get the following notification, and code completion only works for the standard library as you said. That being said, RLS is weird sometimes.
If I had to guess, then I think RLS compiles the code, and at some stage extracts the needed information. Thus if the code doesn't compile, then code completion could be affected. But this is 100% an educated guess.
Alternatively, I have heard praise about using IntelliJ + the Rust plugin, but I haven't used it myself yet.
I have figured out one part: problems with running your code from within the VSCode. I had to modify default code-runner command for rust:
Original command:
"rust": "cd $dir && rustc $fileName && $dir$fileNameWithoutExt",
Changed to:
"rust": "if [ $(basename $dir) = 'examples' ]; then cargo run --example $fileNameWithoutExt; else cargo run; fi",
And now it works, and I can run my code quickly.
Part 2: Autocomplete still is very very bad, unfortunately. I am using RLS. there is this thing racer. Is it a better choice?
Alternatively, I have heard praise about using IntelliJ + the Rust
plugin, but I haven't used it myself yet.
As I mentioned in my previous post, IntelliJ, free edition does not have a debugger from what I can see. I need it.
I am wondering how people get a good autocomplete from Rust?
Alright, so just a disclaimer I suspect this question will be a duplicate of another question however I'm not even sure what to search for.
I have never used Eclipse or Golang before and am attempting to get a basic hello world application to work.
I have installed the goclipse plugin, created a new go package and go command source file. From what I have read to run a project in Eclipse you right click the package, select Run as then set the run configurations. The problem occurs when I attempt to select the go package as none shows up and if I leave it blank it throws a 'Go package not found' exception.
Thank you for any help you can provide.
EDIT: Upon the answers advice I have decided to go with the basic command line, however a friend did also recommend LiteIDE. I will "assume" tmichels answer is correct in regards to getting Go to work within eclipse.
If you don't use the GOPATH environment variable and you don't put your project folder under $GOPATH/src the compiler won't find it. As I see it goclipse lets you skip the GOPATH entirely but in this case you have to put your code under the src directory that you can see in the Project Explorer. See the related section of the goclipe documentation.
Although I think you make your life harder by using a full-fetched IDE for go development. Just use the command line tools. And it has the added benefit that you will actually understand what's going on (IDEs hide this from you).
So for building you can use go build or go install. The latter will copy the binary to your $GOPATH/bin directory. For running test just call go test or go test path/to/package. There is a hidden gem in the go tool: when you are working with multiple packages in the same directory you can use go test ./... to test all of them at once. This also works with other go commands.
I am having quite a bit of trouble setting up Theano to work with my graphics card - I hope you guys can give me a hand.
I have used CUDA before and it is properly installed as would be necessary to run Nvidia Nsight. However, I now want to use it with PyDev and am having several problems following the 'Using the GPU' part of the tutorial at http://deeplearning.net/software/theano/install.html#gpu-linux
The first is quite basic, and that is how to set up the environment variables. It says I should 'Define a $CUDA_ROOT environment variable'. Several sources have said to create a new '.pam_environment' file in my home directory. I have done this and written the following:
CUDA_ROOT = /usr/local/cuda-5.5/bin
LD_LIBRARY_PATH = /usr/local/cuda-5.5/lib64/lib
I am not sure if this is exactly the way it has to be written - apologies if this is a basic question. If I could get confirmation that this is indeed the correct place to have written it, too, that would be helpful.
The second problem is in the following part of the tutorial. It says to 'change the device option to name the GPU device in your computer'. Apparently this has something to do with THEANO_FLAGS and .theanorc, but nowhere am I able to find out what these are: are they files? If so where do I find them? The tutorial seems to be assuming some knowledge that I don't have!
Thanks for taking the time to read this: any and all answers are greatly appreciated - I am very much completely stuck at the moment!
On Linux/OSX:
Edit or create the file ~/.theanorc. The file should contain:
[global]
floatX = float32
device = gpu0
[nvcc]
fastmath = True
[cuda]
root=/usr/local/cuda-5.5/
# On a mac, this will probably be /Developer/NVIDIA/CUDA-5.5/
You need to add cuda to the $LD_LIBRARY_PATH variable. If you're running eclipse, you can go to Project properties > Interpreters > Configure and interpreter ... > Environment, and then add an LD_LIBRARY_PATH variable that points to your cuda lib folder (probably /Developer/NVIDIA/CUDA-5.5/lib64)
Now when you import theano it should print a message about finding the gpu. You can run the test code at http://deeplearning.net/software/theano/tutorial/using_gpu.html to see if it's using the gpu.
THEANO_FLAGS is an environment variable and .theanorc is a configuration file. You can use both mechanism to configure Theano. This is described here.
I never heard of the .pam_environment file. Also, you shouldn't just override the value of LD_LIBRARY_PATH, but append/prepend to it like this:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-5.5/lib64/lib
For Theano, if you define CUDA_ROOT, you don't need to modify LD_LIBRARY_PATH, so I would just remove the last line.
Normally, if your shell is bash, people define the env variable CUDA_ROOT in the .bashrc file like this:
export CUDA_ROOT=/usr/local/cuda-5.5/bin
The change to .bashrc will only be used if you log out and log it again.
So, I've been using Sublime for a while as a simple text editor, but I'm venturing into the land of plugins for work and I've run into an issue getting pylint to work. Specifically I have it installed and have the Sublime package manager working, but I'm not sure how to include paths in my sublime settings.
I haven't found very useful documentation on this point, but if you are willing to point me towards it that would be a perfectly acceptable answer. My basic issue is that currently every time I save a file, the following error message shows up:
"Please define the full path to 'lint.py' in the settings"
I understand this error message which is great, I just have no idea where the sublime settings are or what the standard format for defining a path is. Any help would be appreciated.
There are quite complete directions at the SublimeLinter GitHub page that should describe how to set everything up. Briefly, go to Preferences->Package Settings->SublimeLinter->Settings - Default to see where the different settings are defined. Then, open Preferences->Package Settings->SublimeLinter->Settings - User to change anything, as the main settings will be overwritten when the package is updated. Remember that settings files are in JSON format, so you'll need opening and closing curly brackets to enclose settings, and a comma between them:
{
"sublimelinter_delay": 30,
"sublimelinter_mark_style": "none"
}
I haven't gotten the error you have, are you sure you're using the regular SublimeLinter and not the new beta version? I just installed it fresh on my work machine (I've been using it for a while at home) and after restarting ST2 it's working like a charm with Python.
I had the same problem. I found it to be coming from the package "Pylinter". I removed Pylinter and added SublimeLinter, it covers more than python and is well used. I'm enjoying it quite a bit.
From your command line just run:
sudo easy_install pylint
sudo easy_install pep8
After that restart your sublime.
I encounter the same situation today. In my case, that is because I have not installed the 'pylint' in my system yet. It works fine after I installed the 'pylint' through pip.
Just for other people reference.
so once again, I'm having a little problem I can't figure out myself. Meaning, I'm pretty sure I know what the problem is, I just can't fix it.
I'm developing in C++ using Netbeans 7.01 with CMake 2.8.6. However, when I'm trying to build a project, I get the following error from CMake:
CMake Error: The path to the source directory:
H:/Projects/Netbeans/CppApplication_1/CONF=Release
contains unsupported character '='.
Please use a different source directory name.
Please note, that "CONF=Release" isn't a folder. It seems to be a configuration flag set by Netbeans, as it changes when I'm trying a debug build. So, my guess here is, that theres a space missing, or something similar. Unfortunately, I can't figure out where to change that. There are no options in any related Netbeans window, I can't find anything related in the configuration files for netbeans itself or the project either.
Did anyone here have experienced the same problem and found a solution to it? I would be very glad to hear it. If there's any information missing, let me know, I will add them as fast as possible.
Edit:
Just noticed there is already version 7.1 of netbeans, nice to know. However, even with this version, the same problem occurs.
You must specify the command you ran to allow for the error to be identified. However, it looks like you missed the "source-path" parameter.
The cmake command ends with the path to source and should be something like:
cmake -D CONF=Release <path to source>
