Compile errors

[awong26]

Hi,

I'm trying to install ITKR from inside the R environment and am running into an error during the compilation process. Your help would be appreciated. For reference I'm running the latest version of R and Rstudio on a Windows 7 machine.

Installing ITKR
"C:/PROGRA~1/R/R-35~1.0/bin/x64/R" --no-site-file --no-environ --no-save --no-restore --quiet CMD  \
  INSTALL "C:/Users/Coda/AppData/Local/Temp/Rtmpa8caoE/filee703b617bc1/ITKR"  \
  --library="C:/Users/Coda/Documents/R/win-library/3.5" --install-tests

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

testing on windows is an ongoing process --- i dont know much about it but several people succeed with this, dont know if they were using mingw or not. you might try to pull again to see if you experienced "bad timing" on a commit or something of that nature.

also any help from you or other windows users would be appreciated

I realized that the error is being caused by the temporary path (that gets created during the download/install process) is too long. I got around the problem by manually cloning the repository to a location with a short path name, and then asking devtools to do the build and install manually. That seemed to do the trick!

Actually it still seems to be having issues; although it completed the install process it does not work properly. I'm trying to see how to get it running.
