Using Windows, my Hello World code is in src\hello\hello.go.
When using the command "go run hello.go"
Getting Error like this
# command-line-arguments
C:\go\pkg\tool\windows_amd64\link.exe: cannot create $WORK\b001\exe\a.out.exe: open $WORK\b001\exe\a.out.exe: Access is denied.
This can be caused by an anti-virus application like AVG or G-Data.
You can use the -o argument with go run to specify the output directory, and add that path to the exclude list of your anti-virus should this be the cause.
This usually happens when the executable is being edited in some way, or currently running. Check if you have any spare processes of this executable, or in the worst case, try restarting your computer.
Alternatively, it may also be that the linker genuinely does not have write access to the output directory. Make sure that the directory is writable to the user you are compiling your program as.
Adding code folder to the exception list solved the problem.
Windows Security-> Virus and Threat Protection Settings -> Exclutions->Add folder
Add your workplace folder here where your code exists. Adding temp folder didn't work for me.
go build gotest.go ; .\gotest.exe
Using the above command (regular command prompt.) can eliminate pop-up alerts but don't know the reason.

I have enabled golangci-lint file watcher in GoLand but when I save file I got error like below one:
msg="Running error: context loading failed: no go files to analyze"
After some debugging I found that this error comes when I run golangci-lint without activating my virtual env.
So my question is how do I tell file watcher to run golangci-lint after activating virtual environment?
So, In summary I want this:
Before running any file watcher command, Run this command
source .my_virtual_env_folder/bin/activate
This command is basically activates virtual environment.
I am new to GoLand. I tried to do google search but no luck.
I found a workaround.
Make a executable file, write all the commands there. We have full control on which commands do we want to run and in which order. Then in file watcher "Program", paste the absolute path of this file.
I just wrote source <name_of_the_env>/bin/activate at the top of file and then wrote my main command.
This way it activated the virtual environment and then call the command.
I am running Rscripts on a self hosted Devops agent. My Windows agent is able to access the system's directory where its hosted. Below is the directory structure for my code
Agent loc. : F:/agent
Source Code : F:/agent/deployment/projects/project1/sourcecode
DWH _dump : F:/agent/deployment/DWH_dump/2021/
Output loca. : F:/agent/deployment/projects/project1/output_data/2021
The agent is using CMD in the devops pipeline to trigger R from the system and use the libraries from the system directory.
Problem statement: I am unable to save the output from my Rscript in to the Output Loca. directory. It give an error as Probable reason: permission denied error by pointing to that directory.
Output File Format: file_name.rds but same issue happens even for a csv file.
Command leading to failure: saverds(paste0(Output loca.,"/",file_name.rds))
Workaround : However I found a workaround, tried to save the scripts at the Source Code directory and then save the same files at the Output Loca. directory. This works perfectly fine but costs me 2 extra hours of run time because I have to save all intermediatory files and delete them in the end. Keeping the intermediatory files in memory eats up my RAM.
I have not opened that directory anywhere in the machine. Only open application in my explorer is my browser where the pipeline is running. I spent hours to figure out the reason but no success. Even I checked the system Path to see whether I have mentioned that directory over there and its not present.
When I run the same script directly, on the machine using Rstudio, I do not have any issues with saving the file at any directory.
Spent 2 full days already. Any pointers to figure out the root cause can save me few hours of runtime.
Solution was to set the Azure Pipeline Agent services in Windows to run with Admin Credentials. The agent was not configured as an admin during creation and so after enabling it with my userid which has admin access on the VM, the pipelines were able to save files without any troubles.
Feels great, saved few hours of run time!
I was able to achieve this by following this post.
I'm working on a Rest API with Go, but everytime I try to run my application with
go run main.go
the Windows Firewall tells me that has blocked some features of my app. I would like to know if there's some way to make my executions without have to Accept everytime.
Change
http.ListenAndServe(":3000", r)
to
http.ListenAndServe("127.0.0.1:3000", r)
If you are calling go run main.go following is happening:
your programm is compiled inside a temporary folder
the compiled binary is executed
But the temporary folder is just for one execution. So the next time when you run your programm via go run another folder is used.
The windows firewall does give you always the information which path your server has and if you remember the paths after each time you will see that there is always a different path.
The windows firewall is so configuread that it remembers the path of each programm. So when the path is changing you will always need to comfirm that the new path is allowed to run on that port.
To fix this you should compile your server. Just run go build and exeute the binaries then inside you project folder. Then you will just have to accept just one time.
Hi I had the same problem:
Try that:
Go to Windows Defender Firewall, in Left side menu you saw Inbound Rules click there, then Right Side menu you will see New Rule... click.
Choose Port opened from window -> Next
Select TCP, then define which ports you want I choose 8080 click Next again, Choose Allow the connection Next, Check All Next, Give any Name Goland or anything you want and press Finish. Thats it
based on #apxp answer
in windows cli this works for me
go build main.go && main.exe
this work for me
go build main.go && .\main.exe
and run using makefile
I think #apxp's answer is the complete explanation of the situation; some time after ask this question I found a way to run my application with:
go build -o ejecutable.exe ; if($?) { .\ejecutable.exe }
Just go to your Windows Firewall notification settings:
Control Panel -> Windows Defender Firewall -> Change notification settings
Uncheck the option for Notify me when Windows Defender Firewall blocks a new app to prevent it from showing the popup.
You can use CompileDaemon to auto re-build your project on file changes, because it runs a build anyway, you'll only have to accept once. Plus, your project will re-build automatically!
Install:
go get https://github.com/githubnemo/CompileDaemon
Example usage:
# Assuming your project looks like and you're in your project working dir
# hello/
# hello.go
# Rebuild on .go file edits and run the hello command after
CompileDaemon -command="./hello"
The WSL run under VM, so you have to execute ifconfig
You will see your IP in the section (eth0:) inet x.x.x.x
This x.x.x.x is the IP you have to put in your browser.
I have a question and wondering if you guys could help.. Here are the details -
Program Flow ->
Autosys Job -> Windows .bat job on network path-> Internally calls java program along with few other components
When the .bat runs through Autosys job, it gives below warning and does partial processing and exits out without any failure
(i guess the internal code might not have good error handling..but sadly I do not have access to view/modify the same). However, when I logon to that
windows box and run the .bat file from cmd prompt, it works like a charm and throws no error.
Warning in Logs - "WARNING: Failed to load the sqljdbc_auth.dll"
Things I tried-
I tried creating a wrapper bat file in windows C drive (not the netwrok path where the actual .bat is in) and placed sqljdbc_auth.dll in that custom folder.
Job went to SU , after partial processing.
Appreciate your help.
Many Thanks,
Raj
I'd suspect there is a path error. Try echo %path% just before calling your batch, even simply run
echo %path%>alogfile
call yourbatch
and if the displayed path doesn't include a directory in which your .dll resides, add it into the path before calling yourbatch.
It may very well be that your logon includes the required directory as part of your user-defined path and the username under which the job runs does not include the directory.
Or, you could try moving the dll into somewhere like system32 which should be common to everyone.
(Windows should use the standard path-scanning algorithm to locate any required dll that isn't invoked from a full pathname)
when i save java file error is you dont have permission to save in this location contact the administrator to obtain permission on window7
Don't store application data in the "Program Files" directory.
It is very bad design and regular users don't have write access to that directory (for a very good reason).
So even if you changed your settings locally to open up the door for viruses your application won't run on other computers.
Besides: storing a Java file in the JDK directory serves no purpose at all.
Btw: your uppercase letters are broken, as well as the dot or the comma...
That's normal - jdk/bin is the installation directory of the JDK, regular users cannot (and should not) write files there. You'll have the same problem on Linux/Unix and on Mac OS X, where installation directories are off-limits to regular users.
Write your files to the users home directory (System property "user.home", works across platforms), or let the user choose where you save stuff.
Bin directory do not allow directly to save program in it.
it is so simple, just save your .java file on desktop and then copy paste it in Bin. done ;)
If the file can't save directly to c:\program files\java\jdk1.8.0\bin\
Solution:-
Click start Menu type Notepad command in run run as administrator
Right click the Notepad run as Administrator, then type the program file can save directly to c:\program files\java\jdk1.8.0\bin\
Just try it......
