Trouble installing

[twesleyb]

Hi Daniel, I really appreciate your efforts to make wholebrain as open source and accessible as possible. Thank you! I followed your tutorial to install on Windows, but on one of the final steps I run into an issue. In Rstudio I call the following to install your package from GitHub:

devtools::install_github("tractatus/wholebrain", args='--no-multiarch')

This generate the following message in which there is an error:

I'm hoping your experienced eye can catch the underlying problem. I hope I have provided enough information, but I can provide more info if necessary.

Thanks, Tyler

hi Tyler, I have just got the same problem with you. I wonder if you have found answers to solve this problem, if so, please let me know, thank you very much!

Hi luckylara, I'm sorry I have not found a solution. If you are able to overcome the install problem, please let me know!

@twesleyb you havent set Rtools properly. The C++ compiler "C:/Rtools/mingw_64/bin/g++.exe" is not able to compile a simple test program.

Is Cmake complaining that the compiler cant compile.

Later you have this error:

make: /bin/sh: Command not found

Which means that sh.exe cant be found by the Rtools your Rstudio/R is using. Check your paths.
