Hi guys, I've configured and built the Ruby interpreter with the following options: CFLAGS=-static ./configure --with-static-linked-ext --disable-shared -- without-openssl --without-tk --prefix=/opt/ruby I also have an extension which was built with the following commands # ruby extconf.rb # make gcc -I. -I/opt/ruby/lib/ruby/1.8/i686-linux -I/opt/ruby/lib/ruby/1.8/ i686-linux -I. -D_FILE_OFFSET_BITS=64 -fPIC -static -c clicmd.c gcc -shared -o clicmd.so clicmd.o -L. -L/opt/ruby/lib -Wl,-R/opt/ruby/ lib -L. -rdynamic -Wl,-export-dynamic -ldl -lcrypt -lm -lc When I run the script that requires this library I get an undefined symbol error: # ruby hpm.rb ./clicmd.so: ./clicmd.so: undefined symbol: rb_cObject - ./clicmd.so (LoadError) Any hints on how to solve this issue? Can I use dynamic extensions if I have built ruby with statically linked extensions? Do I need to statically link my extension to ruby? Thanks in advance, Edgardo
