Subject: [Boost-build] [git] genrating forward headers
From: Bjørn Roald (bjorn_at_[hidden])

I am trying the patches for b2 support of generating forward headers.
Latest post on this I found was:
http://listarchives.boost.org/boost-build/2013/06/26812.php
As conversion to git is up and running again, this need some care and I
intended to do some testing to attempt to get the
https://svn.boost.org/trac/boost/wiki/TryModBoost process steps working
smoothly.
The patches I have is derived from Jürgen's patches here:
http://listarchives.boost.org/boost-build/2013/05/26798.php
However as it looked to me most of the changes in tools/build except
from addition of try-build and changes to build-raw in config.jam has
been applied to trunk and thus is part of what git clone provide.
Nevertheless, I am more lost than Jürgen I guess as I get an error in
configure.jam executing this new code:
+# Attempts to build a set of virtual targets
+rule try-build ( targets * : ps : what : retry ? )
+{
+ local cache-name = $(what) [ $(ps).raw ] ;
+ cache-name = $(cache-name:J=-) ;
+ local value = [ config-cache.get $(cache-name) ] ;
build-raw was changed to call try-build like this:
+ result = [ try-build $(targets[2-]) : $(ps) : $(what) :
$(retry) ] ;
+ .$(what)-supported.$(ps) = $(result) ;
however in link.jam we have
if [ configure.try-build $(target) : "symlinks supported" ]
I can not figure out what to put as the missing "ps" or "what" required
parameter here, if anything. Are there some additional changes or later
patches I need?
Call stack is:
