Getting the subversion repository number into code

Question

I\'d like to implement a way of recording the version of a project within code, so that it can be used when testing and to help track bugs. It seems the best version number

Answer 1

in your Makefile, add:

SVNDEV := -D'SVN_REV="$(shell svnversion -n .)"'
CFLAGS := $(SVNDEV) ...

then you can use macro SVN_REV anywhere in your code, eg:

printf ("Version: SVN %s\n", SVN_REV);
