Hello,

I am new with the build boost sytem, before I wanted to use jam, but it was not enough for me.

In the future, it would be good to include some domain information in your subject line, such as "[build]." It would be even better to post to the Boost.Build mailing list (http://www.boost.org/more/mailing_lists.htm#jamboost)

I have 2 quick questions:

- How it is possible to check if a directory is present or not ?

we need more contextual information. Where? How?

- I want to do a system call before building some files, how can i do that (I want to call perforce to sync the files before compiling them....) ?

I think you will get better answers by describing exactly the result you want (without assuming how you will get it), and posting to the Boost.Build list. These are nontrivial questions unfortunately. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
