intro: "NVP" == Nick V Pakoulin <npak(a)ispras.ru&gt; writes: Ok, i thought a little bit, looked at the Makefile and some understanding seems to come to my mind ... Building with pdump results in two files -- executable (temacs) and corresponding dumped lisp. Right? Then why not to keep dumped part somewhere under ${datadir}/${instvardir}/ ? On my system xemacs-21.2-b41-3a68d0b7.dmp is the only non-executable out of 186 files in /usr/local/bin and I strongly objects to filling bin/ with any kind of data files whether they come with XEmacs or something else. bin/ for executables, and share/ include/ lib/ etc-etc-etc for all else. Hope you see my point: I'm not against pdump, I'm for keeping dumped part in an appropriate data dir. Nick. NVP> Today I build xemacs with pdumper for the first time.
