The makeinfo command splits the generated info output in multiple files (in 300 KiB chunks) by default; this meant the build system would have had to install the multiple QEMU.info-1, QEMU.info-2, etc. files for the info manual to work as intended. Instead, keep the info manual as one single file by specifying the --no-split option to makeinfo. * gnu/packages/patches/qemu-build-info-manual.patch (sphinxinfo) <makeinfo>: Invoke with the --no-split argument.

Subject: [PATCH] build: Build and install a Texinfo version of the manual.
 | 
						|
 | 
						|
Take advantage of the Sphinx texinfo backend to generate a QEMU info
 | 
						|
manual.  The Texinfo format allows for more structure and info readers
 | 
						|
provide more advanced navigation capabilities compared to manpages
 | 
						|
readers.
 | 
						|
 | 
						|
* configure (infodir): Add an --infodir option, which allows
 | 
						|
configuring the directory under which the info manuals are installed.
 | 
						|
* docs/meson.build (texi, info): New targets.
 |
