[R-pkg-devel] 'configure' exists but is not executable

[Sebastian Ankargren]

Dear package developers,

I have a package that is dependent upon Rcpp and RcppArmadillo and for this reason I use a configure file. On my local machine with:
R version 3.6.0 (2019-04-26)
Platform: x86_64-apple-darwin15.6.0 (64-bit)
Running under: macOS Mojave 10.14.3

…my package passes R CMD check. However, on Travis CI I get

* installing *source* package ‘mfbvar’ ...
** using staged installation
ERROR: 'configure' exists but is not executable -- see the 'R Installation and Administration Manual'

This despite the configure file being executable locally. Some of my attempts at fixing this include:
- chmod +x configure
- removing configure, committing/pushing, putting configure back and chmod +x configure before committing/pushing again to ensure the executable version is pushed
- creating a new configure from configure.ac using autoconf

All of my attempts have been unsuccessful and I’m a little bit puzzled why it doesn’t work on Travis. Does anyone have any suggestions? The failure is present both on Linux and OS X. I am not sure whether the issue is specific to Travis, but I have no other ways of testing it before submitting to CRAN.

Appreciate any input you might have!

Best,

Sebastian
