Hi,
I've contacted the processx package maintainer on a problem reported
here previously (see
https://cygwin.com/pipermail/cygwin/2020-April/244667.html). He
suggested to try the github version but that triggered a different
type of error which does not seem to be package-specific.
1st try: build from a local copy of the github package sources with
default locale settings on a German Windows 10 system
install.packages("/cygdrive/c/Temp/processx-master",repos=NULL,type="source")
Installing package into ‘/usr/lib/R/site-library’
(as ‘lib’ is unspecified)
* installing *source* package ‘processx’ ...
** using staged installation
Error : Invalid DESCRIPTION file
Authors@R field gives no person with maintainer role, valid email
address and non-empty name.
See section 'The DESCRIPTION file' in the 'Writing R Extensions'
manual.
ERROR: installing package DESCRIPTION failed for package ‘processx’
* removing ‘/usr/lib/R/site-library/processx’
Warning message:
In install.packages("/cygdrive/c/Temp/processx-master", repos = NULL,

non-zero exit status

Noted. I will look on both the two issues but it could take a bit.
I never looked at the build process of R packages in such details
Hi,
kind of "while you're at it": I've noticed one additional problem with
non-ASCII characters. This may or may not be related to the problem
reported above. Several packages throw an error during installation, in
my case questionr, readr, pls, and vegan. The output of the latter is
shown here:
installing to /usr/lib/R/site-library/00LOCK-vegan/00new/vegan/libs
** R
** data
** inst
** byte-compile and prepare package for lazy loading
** help
*** installing help indices
Error in Rd_info(db[[i]]) :
missing/empty \title field in
'/tmp/RtmprL23H1/R.INSTALLffe51949f2e2/vegan/man/sipoo.Rd'
Rd files must have a non-empty \title.
See chapter 'Writing R documentation' in manual 'Writing R Extensions'.
* removing ‘/usr/lib/R/site-library/vegan’
The file in question (man/sipoo.Rd) starts like this:
\encoding{UTF-8}
\name{sipoo}
\alias{sipoo}
\alias{sipoo.map}
\docType{data}
\title{ Birds in the Archipelago of Sipoo (Sibbo and Borgå)}
Please note that the encoding is set to UTF-8 explicitely. Nonetheless,
the a with overring in "Borgå" seems to mess up the title, which makes R
think the \title field is missing. Changing the å to a circumvents this
problem. I've also noticed that non-ASCII characters outside the title
field do not hurt at all.
regards,
Markus
