Emacs bootstrap: 'ignored' errors [trunk]

Emacs bootstrap: 'ignored' errors [trunk]

[Angelo Graziosi]

Just for completeness, the bootstrap log of current trunk (rev.101821) 
shows up the following 'ignored' errors:

[...]

Those errors were absent in the bootstraps of previous revisions.

Hi Glenn,

have you some comments?

I noticed this in 'doc/emacs/ChangeLog':

2010-10-06  Glenn Morris  <>

Ciao,

My comment on ignored make errors is that they should be ignored.

No, as you have seen, 'errors' should never been ignored...

??? Commands that begin with a "-" in the Makefile are written that
way to ignore errors if they happen.

The errors 'ignored'[1] were related to fatal errors which broke the 
bootstrap (out of tree) in rev.101874 [2].

In rev.101887 all seems fixed.

Thanks,
Angelo.

Errors that should be ignored by Make can never break any build.

No, they were not related at all.

The ignored errors are also present in Emacs 23 (and before) and are
harmless. They don't happen to show up in the build log there, so you
remain blisfully ignorant of them.

I haven't said that they break the build.

If I have understood, they were generated by the build out of tree 
(OOT). In rev.101874 there were similar changes (all in docs) *which* 
caused the break in the bootstrap OOT.

In some ways, the 'ignored' errors were the basis of the upcoming fatal 
ones. Perhaps, asking 'why I got these ignored?' could avoid the break 
in r101874: the recent changes in docs did not take into account for 
bootstrap OOT.

Ciao,
Angelo.

This is all bunkum.

For completeness, I did also bootstraps 'in tree' (using the same 
revisions) and the logs didn't show up 'ignored' errors regarding 
'infoclean' [*] (rev.101821, [1]) nor the bootstrap was broken with 
rev.101874 [2].

I did this on GNU/Linux an on Cygwin.

Cheers,
Angelo.

Why?

The following is on GNU/Linux Kubuntu 10.04.

[A] - Out of tree build, rev. 101821
$ rsync -av --delete emacs-trunk/ emacs/
$ cd emacs
$ bzr up -r 101821
$ mkdir build_dir
$ cd build_dir
$ ../configure 2>&1 | tee oot_build.log
$ make bootstrap -j4 2>&1 | tee -a oot_build.log

[B] - In tree build, rev. 101821

$ cd emacs
$ bzr up -r 101821
$ ./configure 2>&1 | tee in_tree_build.log
$ make bootstrap -j4 2>&1 | tee -a in_tree_build.log

$ grep -i error in_tree_build.log

In [B], the 'ignored' errors regard something like 'cp foo foo' _NOT_ 
your changes in 'infoclean'.

Repeating the same with rev. 101874, [A] gives:

$ grep -i error oot_build.log
checking jerror.h usability... yes
checking jerror.h presence... yes
checking for jerror.h... yes
checking for strerror... yes

BOOTSTRAP FAILURE!

Instead, [B] with rev. 101874 has success:

$ grep -i error in_tree_build.log
checking jerror.h usability... yes
checking jerror.h presence... yes
checking for jerror.h... yes
checking for strerror... yes

make[2]: [stamp-vcdiff] Errore 1 (ignorato)

Where 'ignored' recards 'cp foo foo'.

Your changes, at least up to rev. 101874, were affected by this issue: 
they did not work right in a bootstrap 'out of tree', and the 'ignored' 
errors, [A], of rev. 101821, were trying to flag this.

Cheers,
Angelo.
