using shortcuts to name header files

Paul Linsay

I tried to use a shortcut(alias) to point to a C header file but uVision2 couldn't resolve the shortcut when opening the project. So I have a shortcut with the name header.h that can point to header1.h, header2.h, and so on, but Uv2 can't figure out where header.h is pointing. Is there a solution to this beyond the obvious of multiple #includes, etc.?

    "The source code is exactly where such things should be kept."

    I think that the Project can be a perfectly acceptable alternative, provided it is subject to the same control procedures as the source code.

    Unfortunately, many tools (including, IMO, uVision) do not make it easy to maintain and document such stuff.
    uVision is better than some - at least the Project files are plain ASCII text.

    #if defined HEADER_TO_USE

#if HEADER_TO_USE == 2
#include "header_2.h"
#elif HEADER_TO_USE == 3
#include "header_3.h"
#else
#error "Invalid value for HEADER_TO_USE
#endif

#else
#error "HEADER_TO_USE is not defined"
#endif

    You Could define HEADER_TO_USE in a "configuration" header file, included before all others, on the command line, or via the Project options (eg, using different Targets).

    Note the use of #else clauses to catch missing or invalid definitions;

    Note also that it's best to avoid values 0 and 1 - as these are often used as defaults when a symbol is defined (especially on the command line) without assigning a specific value...
