Hello,

Here is an update on my process :

I always get this error when trying to "make index" :
make: *** No rule to make target
'/usr/share/javascript/proxmox-widget-toolkit-dev/APIViewer.js', needed by
'api-viewer/apidoc.js'.  Stop.

Following Thomas' suggestion, I tried to :
touch api-viewer/apidata.js
touch api-viewer/apiddoc.js

But it didn't change anything, so for the moment I edited the Makefile to
comment the "${API_VIEWER_SOURCES}" in the index.html entry, in order to
skip this part.

I then had errors for missing binaries :
rsvg-convert (provided by the librsvg2-bin Debian package)
a2x (provided by the asciidoc Debian package)

So I installed these packages on my desktop. I also wanted to install them
on my Proxmox server, but asciidoc depends on about 200 packages, and I
cannot install all this stuff on the production server. I guess I could
build a developement server, but it seems overkill for a small
documentation update.

On my desktop, I still get the PVE::RESTHandler error, but for a different
target now :

$ make index
./scan-adoc-refs *.adoc --depends .pve-doc-depends.tmp > link-refs.json.tmp
./scan-adoc-refs *.adoc --depends .pve-doc-depends.tmp > link-refs.json.tmp
PVE_GENERATING_DOCS=1 perl -I. ./gen-cpu-models.conf.5-opts.pl
>cpu-models.conf.5-opts.adoc.tmp
Can't locate PVE/RESTHandler.pm in @INC (you may need to install the
PVE::RESTHandler module) (@INC contains: . /etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.32.1 /usr/local/share/perl/5.32.1
/usr/lib/x86_64-linux-gnu/perl5/5.32 /usr/share/perl5
/usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.32
/usr/share/perl/5.32 /usr/local/lib/site_perl) at ./
gen-cpu-models.conf.5-opts.pl line 6.
BEGIN failed--compilation aborted at ./gen-cpu-models.conf.5-opts.pl line 6.
make: *** [pve-doc-generator.mk:23: cpu-models.conf.5-opts.adoc] Error 2

I think I'm going to write patches for the source files without checking
the compile output, it should be OK for small changes.

Best regards.

Sylvain
