Hi, I have run into a problem using "R CMD INSTALL" with the "--with-package-versions" option under Windows. It is a bit obscure, which could explain why other people have not run into it. We happen to have two packages with almost the same name. One name is a subset of the other. The names are "RtTests" and "RtTestsEG1". I have no problem installing "RtTests" and many other packages, but run into problems installing "RtTestsEG1". The "RtTestsEG1" package happens to be a simple example of how to use the "RtTests" package, so it depends on "RtTests" (which is probably the problem). OK, so this is what happens when I attempt to install "RtTestsEG1": $ R CMD INSTALL --with-package-versions --library=$R_LIBS RtTestsEG1 installing RtTestsEG1 package ---------- Making package RtTestsEG1 ------------ adding build stamp to DESCRIPTION installing R files preparing package RtTestsEG1 for lazy loading Loading required package: RtTests ... [lost of lines removed] Loading required package: RtTests Error: evaluation nested too deeply: infinite recursion / options(expressions=)? Execution halted make[2]: *** [lazyload] Error 1 make[1]: *** [all] Error 2 make: *** [pkg-RtTestsEG1] Error 2 *** Installation of RtTestsEG1 failed *** After some digging in the Windows makefiles, I found out that changing the locale from "C" to "us" in the "lazyload" target of $R_HOME/src/gnuwin32/MakePkg, i.e. using "LC_ALL=us" instead of "LC_ALL=C", solves the infinite recursion problem and give an useful message. It still fails but now says: Loading required package: RtTests Warning: S3 methods 'summary.RtTestSetResults', 'print.RtTestSetResults', 'print.RtTestSetResults.summary' were declared in NAMESPACE but not found Error in namespaceExport(ns, exports) : undefined exports: parseTranscriptFile, compareTranscriptAndOutput Error: package 'RtTests' could not be loaded Execution halted It is true that RtTests declares the various functions in its name space, but why can they suddenly not be found? If I load RtTests by itself, i.e. library(RtTests), there is no problem. I happen to have all this working under Linux, so I tracked down the difference. Turns out that under Linux the equivalent to the "lazyload" target is in "/usr/lib/R/bin/INSTALL" and the difference is in the argument passed to "tools:::makeLazyLoading". Under Linux the full package name with version number is used, i.e. "RtTests_0.1-1". Windows just uses "RtTests". So I managed to fix the problem by making Windows use the full package name in the "lazyload" target. I replaced tools:::makeLazyLoading(\"$(PKG)\" with tools:::makeLazyLoading(\"$(notdir $(DPKG))\" If I now reinstall "RtTests", I can finally install "RtTestsEG1". I must confess, that I do not fully understand exactly what it takes to reproduce this problem. I am guessing that all it takes is a package depending on a versioned package. Maybe the similarity in names introduces a problem because of partial matching. I am guessing that has nothing to do with it. To sum up the report. I see two problems: 1) LC_ALL=C causes infinite recursion. It is as if the C locale does not work under Windows. I do not know what the fix is. It is used many places in install scripts and makefiles. Fixing it in the "lazyload" target is not enough. Even with my change I still get "infinite recursion" and no error message if I try to install "RtTestsEG1" without first installing "RtTests". 2) "makeLazyLoading()" in "lazyload" target needs to be called with full package name with embedded version number. I think this is bug under Windows and my fix takes care of it. It took some time to figure this out. I am hoping this report will save other people time. I am note sure if I succeeded in describing the problem clearly. Please do not hesitate to ask for clarification.
