[Scons-users] force rebuild of a specific target

[Roberto De Vecchi]

William,

Thx for the quick answer! I’m mainly using MD5-timestamp decider with no cache. The method that seems closer to my goal is to delete the actual file and then rebuilt it but I would like to do this without having to browse to the directory that contains the target (I’m running with variant dir and a huge tree so finding out the file location is an annoying process !!)

Cheers
Roberto

Also, depending on what decider you are using MD5 vs timestamp you may just be able to touch the file (IE. to change the timestamp).  Also, if you are using caching then the rebuild will just pull the old file from the cache since the dependencies will not have changed.

V/R,

You can move or delete the file in question; this will mark the node as out-of-date which will cause a rebuild.  Is that sufficient?  You can also mark a node as AlwaysBuild if that is more what you are looking for: http://www.scons.org/doc/HTML/scons-user/ch06s09.html

Hi all,

I’m looking for a way to request scons to rebuild a specific target. The best for me would be to find a way compatible with the interactive mode.

Digging a bit in the scons code base I found the option –assume-new that seems to do what I need ( mark a node as out of date ), but it’s not yet implemented.

As an alternative I tried issuing a clean + build commands on specific node, but in this way the clean command is cleaning all the nodes on which my target depends on making the build process too time consuming.

Any idea / suggestion is welcome!

Cheers,
roberto
