Package: dh-r
Version: 120180613
Severity: important
Some CRAN packages for R require x11 at build time when they load the package
towards the end of the 'R CMD build' step. r-cran.mk accomodated that via
## xvfb-run with GL extension and default resolution
xvfbSrvArgs = -screen 0 1024x768x24 -ac +extension GLX +render -noreset
[...]
## call R to install the sources we're looking at
## use this inside xvfb-run if this wrapper is installed
if test -f /usr/bin/xvfb-run; then \
$(makeFlagsCall) xvfb-run -a -n 20 \
-s "${xvfbSrvArgs}" \
R CMD INSTALL -l $(debRlib) --clean \
$(extraInstallFlags) . \
$(builttimeStamp) \
; \
else \
$(makeFlagsCall) R CMD INSTALL -l $(debRlib) \
--clean $(extraInstallFlags) . \
$(builttimeStamp) \
; \
fi
So if xvfb-run is present (in the chroot, say), it is used to wrap the call.
We used that for years.
dh-r skipped that step.
For a package like cairoDevice (aka r-cran-cairodevice), this renders dh-r
unuseable:
** testing if installed package can be loaded
Error: package or namespace load failed for 'cairoDevice':
.onLoad failed in loadNamespace() for 'cairoDevice', details:
call: fun(libname, pkgname)
error: GDK display not found - please make sure X11 is running
Error: loading failed
Execution halted

To reproduce, clone the repo at
https://salsa.debian.org/edd/r-cran-cairodevice
and use the
bug/dh-r
branch. The master and debian branch revert back to cdbs by (yuck) including
a copy of r-cran.mk in debian/rules.
