Legato build issue


#1

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
No toolchain found for target ‘ar6’.
No toolchain found for target ‘ar7’.
No toolchain found for target ‘ar86’.
No toolchain found for target ‘wp7’.

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
-DUSE_CLANG=0
-DHOST_ARCH=i686

Can you give us some more information about your environment?

Also, did you try “make clean” and then “make”?
