hello,

looking at mpi.jam, there is a part that tests some flags for a compiler
wrapper:

 

local result ;

local compile_flags ;

local link_flags ;

    

if ! $(command)

    { 

      # Do nothing: we'll complain later

    }

    # OpenMPI and newer versions of LAM-MPI have -showme:compile and 

    # -showme:link.

    else if [ safe-shell-command "$(command) -showme:compile" ] &&

              [ safe-shell-command "$(command) -showme:link" ]

    {

...

}

 

What does the safe-shell-command do on windows?

Does it use the %PATH% environment variable if defined?

 

$(command) evaluates to mpic++

 

mpic++ -showme:compile outputs some flags properly,

 

if I were to replace $(command) with the mpic++ full path, should I write:

 

safe-shell-command "c:\\Program Files (x86)\\openmpi\\bin\\mpic++.exe
-showme:compile"
