I've tried to install git2R via R and via clone and I always get the same error:

There is a problem with iconv_open. I also installed iconv via Macports and Brew, I tried the following command but I get the same error has above:

R CMD INSTALL —configure-args="--with-libssh2-include=/opt/local/include --with-libssh2-lib=/opt/local/lib --with-iconv-include=/opt/local/bin --with-iconv-lib=/opt/local/lib” git2r

Thank you Paula

Thanks for reporting the issue.

I have updated the test for iconv in the configure script in commit https://github.com/ropensci/git2r/commit/56b94690dbaad4130fd2aae25418ebd8b0b191ab. Could you please test to install from source using e.g.

git clone https://github.com/ropensci/git2r.git
R CMD INSTALL git2r

[stewid]

I think this is the same problem as in issue #216 which has been resolved. Please open the issue again if the installation still fails.

I used:

git clone https://github.com/ropensci/git2r.git R CMD INSTALL git2r

and it works now. Thank you!
