Which library does R link against? If you can find out its name and a function that R tries to use, you can check for the library's (and function's) presence with AC_CHECK_LIB. Or if you need specific headers, there's AC_CHECK_HEADERS. > The same is true for pcre. PCRE is the same.

In fact, R itself has a working configure script that checks for curl/pcre. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
