From: Daniel Berger Date: 2007-06-19T00:20:01+09:00 Subject: Can't build extensions with g++ Hi, Ruby 1.8.6-p36 OS X 10.4.9 $ g++ -v Using built-in specs. Target: i686-apple-darwin8 Configured with: /private/var/tmp/gcc/gcc-5363.obj~28/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=powerpc-apple-darwin8 --with-arch=nocona --with-tune=generic --program-prefix= --host=i686-apple-darwin8 --target=i686-apple-darwin8 Thread model: posix gcc version 4.0.1 (Apple Computer, Inc. build 5363) Sample code: #include "ruby.h" void Init_cvector(){ VALUE cVector = rb_define_class("CVector", rb_cObject); } Whenever I try to build something as simple as the above extension I get this error: g++ -Wall -I. -I/usr/local/lib/ruby/1.8/i686-darwin8.9.1 -I/usr/local/lib/ruby/1.8/i686-darwin8.9.1 -I. -fno-common -g -O2 -pipe -fno-common -c cvector.c /usr/local/lib/ruby/1.8/i686-darwin8.9.1/intern.h:207: error: use of enum 'rb_thread_status' without previous declaration /usr/local/lib/ruby/1.8/i686-darwin8.9.1/intern.h:207: error: invalid type in declaration before ';' token Any ideas? Thanks, Dan
