Notes:
|
|
|
|
Make variable replacements open a can of worms. Sometimes they should
|
|
be quoted and sometimes not. Sometimes their replacement values are
|
|
already quoted.
|
|
|
|
VS variables cause problems. In order to pass the referenced value
|
|
with spaces the reference must be quoted. If the variable value ends
|
|
in a backslash then it will escape the ending quote! In order to make
|
|
the ending backslash appear we need this:
|
|
|
|
"$(InputDir)\"
|
|
|
|
However if there is not a trailing backslash then this will put a
|
|
quote in the value so we need:
|
|
|
|
"$(InputDir)"
|
|
|
|
Make variable references are platform specific so we should probably
|
|
just NOT quote them and let the listfile author deal with it.

/*
|
|
Allowing make variable replacements opens a can of worms. Sometimes
|
|
they should be quoted and sometimes not. Sometimes their replacement
|
|
values are already quoted or contain escapes.
|
|
|
|
Some Visual Studio variables cause problems. In order to pass the
|
|
referenced value with spaces the reference must be quoted. If the
|
|
variable value ends in a backslash then it will escape the ending
|
|
quote! In order to make the ending backslash appear we need this:
|
|
|
|
"$(InputDir)\"
|
|
|
|
However if there is not a trailing backslash then this will put a
|
|
quote in the value so we need:
|
|
|
|
"$(InputDir)"
|
|
|
|
This macro decides whether we quote an argument just because it
|
|
contains a make variable reference. This should be replaced with a
|
|
flag later when we understand applications of this better.
