-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Adding autoconf and bug-m4 to distribution] According to Bruno Haible on 6/22/2006 5:45 AM: > Hi, > > I got two problems with m4-1.4.4b: > > 1) After installing it, automake breaks like this: > > $ automake-1.9 --gnits tests/Makefile > NONE:0: /packages/gnu/bin/m4: `m4_symbols' from frozen file not found in builtin table! > autom4te: /packages/gnu/bin/m4 failed with exit status: 1 > automake-1.9: autoconf failed with exit status: 1 > make: *** [Makefile.in] Fehler 1 > > I had m4-1.4o installed at the same place earlier. m4-1.4<letter> is a beta release, which will be the eventual m4-2.0. There are some known incompatibilities in the frozen file format added in format version 2, that m4 1.4.x is documented to be unable to understand (since it only parses format version 1). In short, downgrading m4 potentially invalidates all frozen files created with the newer version. Ralf Wildenhues already identified frozen file format incompatibilities as an issue for autoconf, and added a patch to CVS autoconf that melts all files when bootstrapping autoconf (in other words, avoids using frozen files leftover from previous runs, in case the bootstrap picks up on a new m4 version), but this was intended for the upgrade transition from m4-1.4.x to m4-2.0 rather than the downgrade transition you mention (since CVS head m4 does not yet parse version 1 correctly, even though it should). All I can say for m4 is that I will more prominently mention in the documentation that downgrading from an alpha release to a stable release probably invalidates all frozen files created with the alpha release; and that people using alpha m4-1.4o should be prepared for such breakage if they choose to downgrade to stable 1.4.5. > > 2) The tarball is lacking m4/gnulib-cache.m4. Without it, > "gnulib-tool --update" effectively removes all gnulib modules from lib/. Thanks; I'll patch this shortly. > > Bruno > - -- Life is short - so eat dessert first!
