Hello Gennadiy,
GR> 1. Why does ./b2 headers on windows creates hardlink for each file
GR> instead of directories? The process takes forever.
tools/build/src/tools/link.jam is responsible for this behavior. In particular
there is a rule that creates links to directories:
rule do-link
{
local target = [ path.native [ path.relative-to [ path.pwd ] $(<) ] ] ;
local source = [ path.native [ path.relative-to [ path.pwd ] $(>) ] ] ;
local relative = [ path.native [ path.relative-to [ path.parent $(<)
] $(>) ] ] ;
if ! [ on $(target) return $(MKLINK_OR_DIR) ]
{
LOCATE on $(target) = . ;
DEPENDS $(.current-target) : $(target) ;
mklink-or-dir $(target) : $(source) ;
}
if [ os.name ] = NT
{
MKLINK_OR_DIR on $(target) = mklink /D \"$(target)\" \"$(relative)\"
;
}
else
{
MKLINK_OR_DIR on $(target) = ln -s $(relative) $(target) ;
}
}
As you can see this rule uses mklink /D to create a symbolic link. However
by default in Windows users have no rights to create symbolic links. You
can try to change /D to /J. I personally solved the problem by using an alternative
command mklnk that exists in Take Command shell I use.
