Can't compile Emacs from source - symlink issue again?

[PhilipDaniels]

Have been trying to compile Emacs from git HEAD. "make bootstrap" fails with

Opening input file: No such file or directory, /root/repos/emacs/lisp/leim/quail/.#tsang-cns.el

I went into that directory and did an ls -al and saw

Just for laughs, I tried

$ cp tsang-cns.el .#tsang-cns.el
cp: not writing through dangling symlink '.#tsang-cns.el'

Is this related to the known symlink problems?

Which version of emacs are you trying to build? https://github.com/emacs-mirror/emacs?

[PhilipDaniels]

Hi Ben, I didn't know about that mirror. After installing dependencies, I did

$ git clone --depth 1 git://git.sv.gnu.org/emacs.git
$ cd emacs
$ ./autogen.sh
$ ./configure
$ make bootstrap

Was on commit ed54b3f at the time I tried. Looks like the same commit is in the mirror too.

[benhillis]

Thanks for the additional info. I tried this locally (after installing a ton of random packages) and the build is succeeding for me. Looks like this was fixed by the same symlink bug fix that is making its way to the flighting branch.

[PhilipDaniels]

That's great, thank you. Please leave the bug open and when a new build is available I will check it.

Adding a link to #6 so we have a record there of symlink issues.

@PhilipDaniels symlink improvements were made in the new Windows build 14328, WSL specific release notes are here
Please let us know if this resolves your issue. If so, we would like to close this one out.

[PhilipDaniels]

Windows updated itself to build 14328 last night, and I have done an apt-get dist-upgrade too, but the problem is still not fixed. Same error as reported above. I re-cloned the Emacs repo before trying to compile again

Opening input file: No such file or directory, /root/repos/emacs/lisp/leim/quail/.#tsang-cns.el

[PhilipDaniels]

Can confirm this is fixed in Build 14332. Cheers!

I have just tried installing emacs.24.5 and make is failing with:

heap (19938104 bytes).  This usually means that exec-shield
or something similar is in effect.  The dump may
fail because of this.  See the section about

EDIT: This may be an emacs issue see moby/moby#22801

sudo apt-add-repository ppa:ubuntu-elisp/ppa
sudo apt-get update
sudo apt-get install emacs-snapshot emacs-snapshot-el

seemed to work for the snapshots
