Displaying the version numbers of the source used in an exec

QNX USERS QNX6 - OS

Hi,

I’m trying to find the way to know version numbers of the source used to genarate an executable in QNX6. We’ve been lately uploading our code to a CVS server so this would be a great deal for us.

We are doing this right now with our QNX4 projects using RCS IDENT and CVS keywords. Basically, we declare a variable containing the information we want to read afterwards:
[static char rcsid[]="$Id$"] [CVS replaces $Id$ with the info]
And then, we get to know revision numbers using the IDENT utility.

But, in QNX6 ther is no RCS or IDENT (correct me if I am wrong). Does anybody know the way to do the same we are doing in QNX4??

I’ve been trying some alternatives but none of them has worked:

  • I’ve tried de #ident directive which the preprocessor ignores.
  • I’ve tried the “use -s” but I am always getting “No info available in …” So, clearly I am putting the information in the wrong place.

BTW, I’m using IDE 3.0 under QNX Momentics 6.3.0 SP2

You can use something like strings | grep ID

Or you can get the info from the cvs update command and stuff the output in the executable using usemsg -I… Then to access the data you via use -i

May I suggest you look at using svn instead of cvs. Much more powerful and flexible. One main advantage is that a single version number identy the whole source tree, so no need to keep track of the version number for each file. I stuff that number using usemsg, which means that with a simple number in 5 years from now I can rebuild the executable.

OK, strings it’s ok for *.c and *.h. But I’ve realised that I cannot use the same method for other files like *.wgtd.
So, then the “usemsg -i” way is the best for me. But I have some questions:

The usemsg manual says that I can also use the option -f to load all the id=value pairs stored in a file. Has anybody tested that? It isn’t working for me.

Also, the manual for USE says that “use -s” should “display the version numbers of the source used in the executable”. Does anybody know where deoes “use -s” look for them?

About SVN, we aren’t using it because of the server box and because we also have clients running QNX4.

QNX4 has a svn client.
