[R-pkg-devel] Help with Windows build failure

[Alexandre Sieira]

Hi, everyone.

I have done some work this weekend to allow the SnakeCharmR package (
https://github.com/asieira/SnakeCharmR) to be compiled under Windows. For
reference, this is an Rcpp-based packages that links to the system's
libpython.

I have been able to test it on my box using Windows 10 and several Python
versions:

* Rtools mingw_64/opt Python 2.7.9;
* python.org 2.7.13 64-bit;
* python.org 3.6.1 64-bit;
* python.org 2.7.x 32-bit on Appveyor (
https://ci.appveyor.com/project/asieira/SnakeCharmR).

Still, when I submit my source package to win-builder I get an error:
https://win-builder.r-project.org/9aqdlW0D6e3m/

https://win-builder.r-project.org/9aqdlW0D6e3m/00install.out shows some
warnings on header files that are outside of my control, but ends with a
successful compilation. However, it compiles only the 64-bit version of the
DLL and gives me this warning:

Warning: this package has a non-empty 'configure.win' file,
so building only the main architecture


Finally, when we look at
https://win-builder.r-project.org/9aqdlW0D6e3m/00check.log we see an error
due to the fact that the package can’t be tested on i386:

** checking whether the package can be loaded ... ERROR
Loading this package had a fatal error status code 1
Loading log:
Error: package 'SnakeCharmR' is not installed for 'arch = i386'
Execution halted
** DONE
Status: 1 ERROR, 1 NOTE


I apologize if this is a beginner’s problem, but this is my first R package
ever and I’m not really used to working with R on Windows. Would appreciate
any guidance and pointers on how to address this and get the package to
pass the necessary CRAN automated tests.

Thanks in advance for your help.
