I have issue when installing legato the first time. I have successfully installed toolchain from legato.io/legato-docs/latest … build.html. Problem is than when I execute make command at the legato-af I get error about the invalid pch-files. I read somewhere that problem is solved if those files are deleted (and rebuild during make) but I can’t locate the pch-files.
heiautio@Linux:~/legato/legato-af$ make

Create the build/tools directory, run cmake in there to construct Makefiles, then run make.
mkdir -p build/tools &&
cd build/tools &&
cmake …/…/framework/tools/mkTools
