Dear list, I installed R 2.3.1 on a solaris machine. The first time, I used the wrong option --enable-shlib, the installation went smoothly (glitch 1), but of course did not generate libR.so. So, I ran ./configure again with --enable-R-shlib, make and make install went well but still there was no libR.so generated (glitch 2). Finally, I removed the build directory and started fresh, and everything went well. I should have used the correct options, or should have used make distclean afterwards, but the fact that configure/make did not complain may be considered as bugs. Regards, Bo
