Cryptic error message from namespaceExport

R devel mailing list
Dear all,

Today I got this error message (R 3.6.1) when installing my package:

Error: package or namespace load failed for ‘inlatools’ in
namespaceExport(ns, exports):
 undefined exports: .__C__inla

My package was using setOldClass("inla") and exported the "inla" class via
the NAMESPACE. It imports functions from the INLA package. Older versions
of the INLA package did not export the "inla" class. Hence the use of
setOldClass().
The current version of the INLA package does export the "inla" class
through it NAMESPACE. This triggered the error described above.

Is the possible to improve this error message? The current message is
misleading as neither packages contain the string ".__C__inla"

Best regards,

Re: Cryptic error message from namespaceExport

Just to clarify, your package is exporting a class that is not
defined? Or is it exporting a class that is defined by a dependency
and then masked by setOldClass()? A simple reproducible example would
help.

Re: Cryptic error message from namespaceExport

R devel mailing list
Dear Michael,

my package has setOldClass("inla") and the NAMESPACE
contains exportClasses(inla) and importFrom(INLA, inla.posterior.sample)

the old version of INLA uses the S3 class "inla" but does not export it.
the new version of INLA has setOldClass("inla") and the NAMESPACE
contains exportClasses(inla)

installing my package in combination with an older INLA version works

install.packages("
https://inla.r-inla-download.org/R/stable/src/contrib/INLA_18.07.12.tar.gz",
repos = NULL)
remotes::install_github("inbo/inlatools", upgrade = FALSE, force = TRUE)

installing my package with a recent INLA versions yields the error

install.packages("
https://inla.r-inla-download.org/R/stable/src/contrib/INLA_19.09.03.tar.gz",
repos = NULL)
remotes::install_github("inbo/inlatools", upgrade = FALSE, force = TRUE)

Warning: INLA is a very large package. The old version is 87 MB, the new
one 250 MB
