Hi I'm new to jam. I am working on a project that is built with boost jam (version 3.1.13), using almost none of the provided rules. I am trying to break the code into smaller projects that can be built independent from each other. Each project needs to compile/link with a specific version of some common code that is in a separate directory. I would like the intermediate build files to go in a separate directory tree, organized by source directory location so that the common code doesn't need to be rebuilt for each project.
I have set up a basic project to experiment with that doesn't use any of our custom rules. I have TOP defined in my environment. From TOP my directory structure looks like this:
TOP:
Jamrules
TOP/src:
Jamfile hello.cc
TOP/swap_code:
swaps.cc swaps.hh
My Jamrules file defines only the compiler options/locations to work with the basic jam rules.
Here is TOP/Jamfile:
#######################
SubDir TOP src ;
SubDir TOP swap_code ;
Main hello : hello.cc swaps.cc ;
#######################
With this setup, src would represent the main project a user is trying to build, and swap_code represents the read-only code that must be compiled/linked with the files in src. Now when I run Jam from TOP/src, all of my files end up in the exact wrong location, the swap_code directory:
-> ls ../swap_code/
hello ; hello.o swaps.cc swaps.hh swaps.o
I'd really appreciate any help that can be provided. I've spent over a week scouring the web/www.boost.org/perforce site/mailing lists/etc trying to find how to do this. ; If someone could point out what I'm doing wrong, or point me in the right direction I'd really appreciate it.
Thanks in advance,
Ashley
