[Message part 1 (text/plain, inline)]

Hello,

Since my update to last fedora version (fedora 29), I'm unable to build the emacs-26 branch out of tree (ie. on an subdir called build-26).
Note that the compilation on the tree still works.

I'm attaching the trace file of compilation output.

[emacs-26.outoftree.err.C.trc (text/plain, attachment)]

[Message part 3 (text/plain, inline)]

I tried many things, like to build the 26.1 version but whatever I try, this fail.
I someone has a clue on how to start to find a solution ...

I think the above is the root cause.  Where's loaddefs.el being
generated?

I'm unable to find the file.
I tried with the following command:
find . -iname loaddefs.el in my ~/Travail/VCS/Emacs/emacs/emacs-26  directory
It seems the generation of this file has failed.

Then Emacs should have loaded ldefs-boot.el instead, and I see in your
trace that it did.

Is your source tree clean?  Or was it used for another in-tree build?

Anyway, I cannot see what all this could have with your OS update.

It's clean, and i also re-created the build-26 directory

I don't too, but as it's the only thing that changed ...

I can't reproduce the problem on my Fedora 29 x86-64 platform. My build 
log is attached (compressed). One difference is that I didn't use the 
configure argument "--host=$(rpm -E 
'%{_arch}-fc%{fedora}-%{_host_os}%{_gnu}')", which caused ar, ranlib, 
and pkg-config to not be found on your platform. What happens if you 
omit the --host argument?

Also, the first command discrepancy is that my build log says "GEN 
../../../etc/charsets/8859-2.map" and similarly for other *.map files, 
whereas yours does not, and there are other places where it appears that 
your directory contains files that are already built and may have the 
wrong contents. I suggest looking into that.

Hello Paul,
First, thanks for the time you spend on this and sorry for the delay in
my response.

Nothing change. I've tried many variant :

- with only --prefix=/usr/local
- without anything
- without --host=...

After each try, this fail with the same error.

I've also done some experiments :
- in a directory on the side of my emacs-26 source: everything work as
expected.
- after deleting the build-26 directory and re-applyed the following
commands:
  1) git clean -dfx
  2) ./autogen.sh
  3) mkdir build-26 && cd build-26
  3) ../configure with the same options as yours
and this doesn't build.

FYI I've attached my traces and also 2 diffs:
- one after the configure step between my two build-26 dirs (the one
beside of the emacs-26 directory and the other inside). -- emacs-26.outoftree.diff

- one between your traces and mine for the build inside
emacs-26/build-26 (for this I've stripped off the paths before
emacs-26. eg. removed /home/...) -- emacs-26.outoftree.diff.eggbert.diff

For the second diff I've found that the my temacs dump has lesser size
than yours and of course the "Nothing to be done for 'compile-first'."
for 'emacs-26/build-26/lisp' directory

I'm felling like if I've jumped inside the rabbit's hole of Alice.
If you see something that make sense to you ...

How about if you try cloning afresh into a new directory in a different 
filesystem? Something like the following. The 'git clone' will take a 
while but if this doesn't work then we can try to figure out why:

cd /tmp
mkdir d
cd d
git clone -b emacs-26 git://git.sv.gnu.org/emacs.git
cd emacs
./autogen.sh
mkdir build-26
cd build-26
../configure --with-dbus --with-gif --with-jpeg --with-png --with-rsvg 
--with-tiff --with-xft --with-xpm --with-x-toolkit=gtk3 --with-xwidgets 
--with-modules --with-mailutils 'CFLAGS=-O2 -g0'
LC_ALL=C make

Also, please check your environment (run the 'env' command) to see if 
there's something funny in your PATH, or something like that. For 
example, you should be running git 2.19.1, make 4.2.1, gcc 8.2.1 20181011.

I've followed your advices and tried in my /tmp directory. Everything is
working as expected : emacs build successfully.

I then cleanup my git repo (another time with git clean -dfx), trashed
my emacs-26 worktree. Then I recreated it and successfully build my
emacs.

I'm sorry for the annoyance and I therefore close the bug.
