Core archive (core.a) was locked by the virus checker.

I get this 

INFO: Core archive (core.a) was locked by the virus checker.

when I want to upload a STM32 Nucleo Project. Clicking 'Build>Clean Solution' did not resolve the issue. Projects for other Boards (ESP32, Raspi Pico) do not have this problem.

Thanks
Richard

Which virus checker are you using? Visual Micro (apps) don't have any control over this and that error message is produced by windows or the virus checker.

One option might be to exclude the core builld folder from virus checking.
C:\Users\RK_2\AppData\Local\Temp\VMBCore\arduino20x

I tried to exclude this folder

C:\\Users\\RK_2\\AppData\\Local\\Temp\\VMBCore\\

but there is no such folder. I tried   

C:\Users\RK_2\AppData\Local\Temp\arduino

but this didn't help.

Thanks
Richard

You can see the folder in your build output. neither of the two examples you tried matched the example I proved

C:\Users\RK_2\AppData\Local\Temp\VMBCore\arduino20x

The directory of core.a is 

57339eccdd9a\\core.a

Therefore I excluded both folders

dd9a\
dd9a\core\


but the error remains:

\\xpack-arm-none-eabi-gcc\\12.2.1-1.2/bin/arm-none-eabi-gcc-ar" rcs c57339eccdd9a\\core.a" c57339eccdd9a\\core\\abi.cpp.o"
ar.exe: 57339eccdd9a\\core\\abi.cpp.o: No such file or directory
INFO: Core archive (core.a) was locked by the virus checker. Retry 3.
\\xpack-arm-none-eabi-gcc\\12.2.1-1.2/bin/arm-none-eabi-gcc-ar" rcs c57339eccdd9a\\core.a" c57339eccdd9a\\core\\abi.cpp.o"
ar.exe: 57339eccdd9a\\core\\abi.cpp.o: No such file or directory
Error creating archive. This is usually caused by a virus checker locking the archive file (core.a)
    note: The core.a file will now be invalid. Please click 'Build>Clean Solution' to reolve the issue.
          Please report this issue to https://www.visualmicro.com/forums. Let us know which virus checker and board you are using.
Debug build failed for project 'STM32-Nucleo-C0'


What did I confuse?

Thanks
Richard

It might be a permissions error or lack of disk space. We don't have other reports of this and the same folder is used by all users, has been for years. The error message from the compiler states the virus checked is causing the issue.

The specific folder below arduino20x should not be specified. It will change based on your board settings.

You also have wrong paths. the core you are using is in 9e02eb6cce54b1c4308c57339eccdd9a

You need to look in the build output for the paths. Don't use \\, only single \.

We made some changes in recent releases that should have resolved this.

Thanks for trying to fix that problem.

But now I get this error message:
Code
Select All
cmsis_gcc.h: In function __get_CONTROL
cmsis_gcc.h:219: sorry, unimplemented  Thumb-1 hard-float VFP ABI
   219 | {
   | ^
Error compiling variant
Build failed for project 'STM32-C031C6'


I never got this message before. Can you fix it too?

Thanks 
Richard

Sorry, but I forgot to mention that I installed the update.

We need to see the build info. Please attach a build output as per yellow box above.

Concerning my reply #7:

Strange! I created a new project and now it works.

Thanks

Thanks, it was an issue building the core. Potentially down to board options.

It would be useful to see a full output from the project that works.

Click "Build>Clean Solution" then build. That will make a full build so that we can compare with the failed one.

I forgot to clean the project before my last post.

Here it is now after cleaning the project.

Thanks, we need to do some testing but it looks like you switched briefly to another nucleo using the board selection options. Some of the boards listed in the options set the -mfloat-abi=hard compiler flag and that was being set for your build even though you weren't using a board that specified it.

Should not be in the build ...

build.fpu=-mfpu=fpv4-sp-d16
build.float-abi=-mfloat-abi=hard

We will do some testing. Out of interest, when you hit the problem did an ide restart resolve the issue?
