compileCommands setting does not appear to account for --sysroot/target options #1575
Description
* Ubuntu 16.04
* VS Code version 1.20.1
* C/C++ extension version 0.15.0
I'm cross compiling and using the --sysroot option with gcc. The extension does not seem to account for this when loading the compile_commands.json file. It correctly includes the header paths specified with the -I option to gcc, but does not include the headers in e.g. sysroot/usr/include.
Removing all entries from both includePath and browse.path did not fix this issue.
Adding the sysroot/usr/include directories to includePath gave me the functionality I was expecting from the compileCommands setting

We should be able to add support for --sysroot for the next update.

We haven't added --sysroot parsing to compile_commands.json yet, but as an alternative you might be able to set the compilerPath and add the --sysroot arg , assuming all your files use the same sysroot arg.

Thanks, that’s what i ended up doing until this is added to the extension.

Fixing #1755 might fix this too.

I can also confirm that the isystem paths in compile_commands.json do not take into account the --sysroot param.
