Subject: [Boost-build] How to override variable during install
From: Avi Bahra (avibahra_at_[hidden])

Using Boost.Jam Version 3.1.14. OS=LINUX
I want to override the installation directory that was specified via an
environment variable. i.e in my Jamroot.jam
alias install : install-server install-client install-simulator ;
install install-server : Server//install : <location>$ECF_INSTALL_DIR
install install-client : Client//install : <location>$ECF_INSTALL_DIR
install install-simulator : Simulator//install : <location>$ECF_INSTALL_DIR
explicit install-server ;
explicit install-client ;
explicit install-simulator ;
explicit install ;
This all works OK. ECF_INSTALL_DIR is an environment variable
However when I do:
bjam install -s ECF_INSTALL_DIR=$HOME/bin
It ignores the -s, and still uses the environment variable setting.
The documention for -s says:
Set the variable *var* to *value*, overriding both internal variables and
variables imported from the environment.
have i missed something obvious , as this does not appear to work ?
Any help appreciated.
