I have gone through the Nordic Academy to install the tools and build the first example which is blinky. I am using MS Visual Code and SDK version 1.9.1. I have seen some similar questions but the suggested solution of deleting the files in the 'ToolchainCapabilityDatabase' did not help.
I have tried a number of the exercises and it always locks up after it tries to do the build. It seems to complete the steps to setup the configuration successfully but locks up early in the build process. I suspect that it is a conflict with something else on my PC. I have a good number of other development tools installed on my machine.
I see when it reaches about step 4/162 that a task starts called ccache.exe. I have found that if I abort the build that I cannot delete the files until I terminate that task. We do not see that task start on a coworker’s machine.
I have tried deleting everything and installing it again but the same thing happens. I am running Windows 10 (64bit) on a Lenovo PC.
When the build locks up, I have a couple of files in the build/CMakeFiles directory that seem to point out some issues. I have attached these files. The error file contains the message “exit.c:(.text.exit+0x2c): undefined reference to `_exit'”.
When I do the build configuration, I see the following output in the terminal. The output looks the same as a coworker until mine hangs.
