Hello:
I recently upgraded to R 3.4.0, and I've so far been unable to
"install.packages('RODBC')" or "R CMD INSTALL RODBC_1.3-15.tar.gz". Both
end with the following:
configure: error: "ODBC headers sql.h and sqlext.h not found"
ERROR: configuration failed for package ‘RODBC’
I had RODBC installed in R 3.3, but that was before I upgraded to
macOS Sierra 10.12.4. I've tried to RTFM, but I don't know which FMTR,
and I can't decrypt the documentation I've found that seem relevant. I
couldn't find the answer in Ripley's "ODBC Connectivity" vignette.
"iodbc-42.5/iodbc/README.MACOSX" says, "You first need to install
the latest Mac OS X Developer Packages, which can be found at
"http://developer.apple.com/tools";. I think I've done that, but I don't
know how to check it.
"iodbc-42.5/iodbc/README.MACOSX" continues, "Then, you can open
the Xcode Project Builder files under mac/iODBCinst, mac/iODBC,
mac/iODBCtest and mac/iODBCtestw,". I don't know how find any of
these. It further continues, "or execute the following commands from a
terminal session to build all the frameworks and demo applications:
$ cd mac
$ make"
I just did "$ cd mac" and got, "-bash: cd: mac: No such file or
directory". Evidently, I need to substitute something for "mac" here,
but I don't know what.
Suggestions? Thanks,
Spencer Graves
