Subject: [Boost-build] Building an executable, then running it
From: k h (xerceslist.kh_at_[hidden])

I would like to compute a tag so it would contain the current version of the
library being built. The version is in a C++ header, so I thought I could:
i) build an executable that prints the version
ii) run it
iii) use the output to determine the tag
The following bjam file will print the version correctly the *second* time
it is run. The first time it says "sh: tmp/showversion: No such file or
directory", then proceeds to build and install tmp/showversion. What am I
doing wrong please? Many thanks.
exe showversion : showversion.cpp : <include>$(BOOST_INCLUDE) ;
install tmp : showversion ;
DEPENDS version : tmp/showversion
rule version ( )
{
return [ SHELL tmp/showversion ] ;
}
echo [ version ] ;
