Failure building Emacs on WSL

Failure building Emacs on WSL

[Angelo Graziosi]

I build Emacs master on different system (Win64, GNU/Linux, OSX, WSL) monthly, but now it fails on WSL (Window Subsystem for Linux):

  [...]
  checking for brew... no
  configure: error: You do not seem to have makeinfo >= 4.13, and your
  source tree does not seem to have pre-built manuals in the 'info' directory.
  Either install a suitable version of makeinfo, or re-run configure
  with the '--without-makeinfo' option to build without the manuals.
  GNUmakefile:72: set di istruzioni per l'obiettivo "Makefile" non riuscito
  make: *** [Makefile] Errore 1

This didn't happened less than a month ago.. What changed? 

Thanks..

Well, do you have makeinfo >= 4.13?  If not, then the build process
now identifies this problem correctly where it previously failed to do
so.

If you do have makeinfo >= 4.13, then it's some kind of bug in the
configure script.

I don't have it but the build I did a month ago has the info/*.info files so is a mystery what created them a month ago... unless some WSL update (apt update, upgrade etc. ) has removed it... :(

I don't want to install the texinfo package which would install a bunch of texlive packages (I already have TeXLive installed from its site...)

In any case, thanks for clarification.

 Angelo

The change is probably related to Bug#29931

If there's an info/emacs.info file, the error will not show up.

AFAIU, you should be able to configure --without-makeinfo.

You should check if you will get that many dependencies on top of TeXLive.
Because with MSYS2, the makeinfo package installs nothing that would
duplicate stuff in TeXLive.
Actually, I use TeXLive/w32 together with MSYS2 and its makeinfo package.

Now everything is clear.

Up few week ago I had 'C:\msys64\usr\bin' In the Windows PATH and I have MSYS2-texinfo package installed (it installs nothing about TeXLive because MSYS2 has not texlive packages).

So the Emacs build on WSL used makeinfo of MSYS2-texinfo! Now that I removed that path from PATH (following suggestions from INSTALL.W64) the issue came out!

Thanks,
  Angelo.

When is 'makeinfo' used building Emacs?

If I build with

  ./configure..
  ./make...
  ./make install

is it really used? Or is it used only in something like this

  make doc

etc.?

It's not used if you're building from an Emacs distribution tarball, 
which is intended to be portable even to platforms lacking many 
developer tools. It is used if you're building from Git, where it's 
assumed you have a development environment with the appropriate tools, 
one of them being GNU texinfo.

It's probably best for you to arrange for your preferred environment to 
have all these tools. If that's not possible for some reason, you can 
first use GNU/Linux to create a tarball, and then copy the tarball to 
your more-limited development environment and build from that.

When the build process detects that your Info manuals (in info/) are
out of sync with their Texinfo sources (under doc/*/).

Yes, it will be, by default.  If you configure --without-makeinfo, the
manuals will not be built even if that is necessary (because they are
missing in the build tree or outdated).

Is the Cygwin Texinfo installation really so heavy-weight?  Is it not
possible to install only Texinfo, without TeX?  If you don't have TeX,
you will be unable to produce the printed versions of the manuals
(PDF, DVI, PS formats), but if you never need that, TeX is just (a lot
of) ballast.  So in that case, just installing Texinfo alone, which is
a relatively small package, will allow you to build the manuals when
you build Emacs from Git, and get the latest manuals to go with the
binaries you built.

Thanks for claryfication...

MSYS2 has not texlive packages so its texinfo package install only makeinfo and some other utility but WSL (the Windows Subsystem for Linux in W10) wants to install also some texlive package when one installs texinfo...

The issue was originated by the fact that I removed C:\msys64\usr\bin from Windows PATH so in the previous builds the WSL build of Emacs was really using the MSYS2 makeinfo.

Thanks,
 Angelo.
