%e is the package Epoch. It's in the manual. http://www.finkproject.org/doc/packaging/format.php?phpLang=en#percent And you didn't use %type_raw[e] and/or %type_pkg[e]. If you don't use THE SYNTAX WHICH IS SUPPORTED, things won't work. > In Alex' package approximately 100 times the self-defined type variables are > used, but I don't understand what they are doing, how they are used, how they > are substituting themselves with something clear and reasonable and > previously set. > Let's leave out the booleans. I set Type: gcc (4.7) because A) I wanted only to have to change the gcc version in one place if decided to use a different gcc4N. B) I needed both "4.7" and "47". %type_raw[gcc] picks up the raw value, which is 4.7. %type_pkg[gcc] removes all of the '.', and so it gives 47. So, for the current value of Type: gcc, "gcc%type_pkg[gcc]" is "gcc47", and "gcc-fsf-%type_raw[gcc]" is "gcc-fsf-4.7". If I change Type: gcc to 4.8 when we get a Fink gcc48 package, then "gcc%type_pkg[gcc]" changes to "gcc48" and "gcc-fsf-%type_raw[gcc]" changes to "gcc-fsf-4.8" >> The fink packaging manual http://www.finkproject.org/doc/packaging has a >> whole section about this topic, including a full list of all available >> expansions and the origins of their values (including the various ways of >> getting the Type tokens). > > There is a chapter "2.3 Percent Expansion".

But here's the summary Type: foo (value) is the ONLY mechanism currently by which you can add anything resembling a variable 'foo' to a .info file, but the ONLY methods to access the are %type_raw[foo] and %type_pkg[foo]. > -- > Greetings > > Pete > > I wouldn't recommend sex, drugs or insanity for everyone, but they've always > worked for me. > – Hunter S.
