Issue #1261 has been updated by Daniel Golle. File Makefile added File mkmf.log added Update: Including DESTDIR="#{ENV['DESTDIR']}" helps when compiling, and I gained a working shared library from that. But the Makefile generated by mkmf just prepends the DESTDIR to the prefix which causes a horrible mess when make install is called given another DESTDIR. This is a common situation when creating stripped-down binary distributions, as we don't want to include all the headers and development files needed for building a packet. If you agree that this is supposed to work differently and indeed is a Bug, I'd happily work on mkmf.rb to fix it. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1261 ---------------------------------------- http://redmine.ruby-lang.org
