Full_Name: Earl Kinney Version: 2.4.0 OS: Red Hat Enterprise Linux 4 Submission from: (NULL) (140.247.116.214) At HMDC, we make use of the cross building tools to build Windows R libraries on Linux. Recently when attempting to update the cross building environment to 2.4.0 we encountered a linker error. The error reference an undefined symbol "__pcre_ucp_findprop". After walking through the code there appear to be a combination of two problems: 1. Some of the PCRE code does not properly wrap ucp calls with appropriate "#ifdef SUPPORT_UCP" directives. I plan to report this to the PCRE developers. 2. In R, the implementations for this ucp function are removed, as R does not link against the entire pcre library. I was able to get around this problem by including the following files directly from the PCRE distribution and adding them to the makefiles: pcre_ucp_searchfuncs.c ucptable.c As this is such a trivial change, if you could please consider adding this to future releases of R with this release of PCRE, I would be most appreciative.
