Dear R experts, I am testing my R package 'fsbrain' using the Winbuilder service [1] before submitting a new version to CRAN.
All checks pass under R versions 4.0.5 and 4.1.0 alpha, but the installation fails under R 3.6.3 because of a problem related to rgl, which is a dependency of my package. The file 00check.log says 'installation failed' and refers to '00install.log', which contains the following message: ------------------Message start------------------------- * installing *source* package 'fsbrain' ... ** using staged installation ** R ** inst ** byte-compile and prepare package for lazy loading Error in system.file(paste0(dir, "/rgl", .Platform$dynlib.ext), package = pkg, : no file found Warning: Loading rgl's DLL failed. Warning: Trying without OpenGL... Error in system.file(paste0(dir, "/rgl", .Platform$dynlib.ext), package = pkg, : no file found Error: .onLoad failed in loadNamespace() for 'rgl', details: call: fun(libname, pkgname) error: Loading failed. Execution halted ERROR: lazy loading failed for package 'fsbrain' * removing 'd:/RCompile/CRANguest/R-oldrelease/lib/fsbrain' * restoring previous 'd:/RCompile/CRANguest/R-oldrelease/lib/fsbrain' ------------------end------------------------- The full output of the build process can currently be found at https://win-builder.r-project.org/5Mr7luWmfUNL/ To me it seems that rgl cannot be loaded on the test system, but I do not fully understand the message and what to do about it. I hope somebody here can comment on the message and suggest a solution. The source code for my package is at https://github.com/dfsp-spirit/fsbrain.
