Dear R-helpers, I have been trying to use the 'configure' feature offered to package writters... but could make it work. The matter may have been discussed before, and a rtfm answer with the place the answer is found is perfect (but I read the 'writing R extensions' manual). The problem is: In my C code I have code conditional to a defined macro. I used autoconf the naive way (I am not an autoconf wizard) but the Makefile generated seems of no use. Forgetting the use of something like 'DEFS=@DEFS@' I tried to append say ' -DHAVE_ZLIB' to the 'CFLAGS' variable but it did not give anything. (note: I am using R-1.3.0... I plan to update) Any idea ? Thanking in advance... Laurent -- Laurent Gautier CBS, Building 208, DTU PhD.
