We are -- for about 5 seconds after we modify configure.ac to require a specific version of a certain package. Thereafter, the required versions are recorded in configury, and nowhere else. For example: WEBKIT_REQUIRED=2.12 WEBKIT_MODULES="webkit2gtk-4.0 >= $WEBKIT_REQUIRED" This is quite self-explanatory, right? The problem is to collect all these requirements, express them in human-readable form, and then keep that up-to-date whenever the configury changes. That's a non-trivial manual work. Btw, the info you are looking for is generally available on the Internet. I like to use http://www.linuxfromscratch.org in such cases, in particular see http://www.linuxfromscratch.org/blfs/view/svn/postlfs/emacs.html (It still doesn't show Emacs 26, but it probably will soon.) > It would be very helpful if configure specified what it is > specifically looking for, and includes what it needs in the error > message. It does. In your case, it didn't find the package-config file for the relevant version, so it only could tell you that webkit2gtk-4.0 is not installed. Once you install it, if its version is older than the one required, you'd see a message saying it looked for version X.Y.Z, but didn't find it. > It seems that the new emacs silently quit last night while the screen > was locked. I may need to retreat to the previous release (25.3). I suggest to look in the system message log to see what happened. If it crashed, please consider submitting a bug report. > Something else I notice is that when I open a file which is in a > Mercurial repository, the /usr/bin/hg program crashes and I get an > Ubuntu crash report.

Please submit a separate bug report using "M-x report-emacs-bug", and please include in the report the relevant details, such as the hg command issued by Emacs and the Python backtrace. Thanks.
