I’m trying VisualGDB 5.3 r8, and have confirmed a problem for openSUSE(13.1 and 43.1, 43.2).
Using openSUSE and target machine, quit some header files within the asm directory, like errno.h, fcntl.h, are not automatically copied to RemoteSourceCache folder. But with Ubuntu 14.04, no such problem.
Could you please check into this problem and get it fixed?
Different Linux distros may have slightly different include directory layouts, so please double-check that the files actually exist in the same directory on the other machine (please also double-check that you are looking at a correct folder on the Windows side – the dir.txt file should contain the remote directory name).
If you can confirm this, please try reloading all include directories via VisualGDB Project Properties. If this doesn’t resolve the problem either, please check that you can access the header files from your current user account (incorrectly set permissions would prevent VisualGDB from synchronizing those files properly).
