GNU binutils for cross-target application development. Prerequisite for the GCC cross-compiling environment. Use TGTARCH switch to select target architecture, and TGTABI to select ABI. E.g. the following command will build binutils for rtems on sparc: % make TGTARCH=sparc TGTABI=rtems If you encounter any problems building/using/installing this port, please make me know. It would help to improve this port in feature. WWW: http://sources.redhat.com/binutils/
