The .in files are processed by Configure.pl to create the real files.

perl Configure.pl ...

should do it, possibly after 'make realclean'.

hi,

as my attempt to write a lua compiler is continuing (slowly but surely),
and quite some stuff is working already (although rather s l o w), I
decided it was time to write the PMCs representing the various Lua
datatypes. I understood from my previous postings (and replies on those)
that PMCs can be either implemented in PIR (although they are really
created as objects, right?), or in C as .pmc files. I get the feeling
writing them in C as .pmc files is the way to go, so I started with the
first pmc for the lua language: LuaNil.pmc. Whenever a variable hasn't
been assigned a value, its 'value' is "nil". (pretty much the same as
None, I think).

According to the README file in the 'dynclasses' directory, adding
dynamic PMCs can be done by:

1. write the PMC
2. edit parrot/config/gen/makefiles/dynclasses.in
3. make

In my case this didn't work. Editing the dynclasses.in file didn't
trigger the make system to make my PMC.
After getting a fresh parrot, before making it, I added my pmc file,
edited the dynclasses.in file, and started making parrot. This works (of
course), but it's a bit cumbersome to do this everytime I'm adding a
PMC. Anybody got an idea what may go wrong?

thanks,

klaas-jan

thanks, that works. I sent a patch to update this document a minute ago
(it's only a minor detail, but it may help other beginning PMC writers
and prevend this question being asked again)
