Prior to version 1.7, the versions were identified by the top +line of the ChangeLog. + +Define USG with `-DUSG' when compiling these programs to run on system V. + +COFF is not supported, but we do support a way of encapsulating GNU +executable files with COFF headers. Use -DCOFF_ENCAPSULATE when you +compile, to enable this feature. + +In order to use encapsulation, you must use entirely GNU tools, +including these plus GAS, GCC and GDB. You will need to convert the +system libraries to BSD object file format. Use the shell script +libconvert (which uses robotussin) for that. + +The GNU version of ld has some interesting features: + +1. Undefined and multiply-defined global symbol errors +are now associated with specific source files and line numbers, +and printed in a format M-x next-error can parse. + +2. Normally no output is written if there are serious errors. +Use the option `-noinhibit-exec' if you want an output file anyway. + +3. Global symbols can be defined by indirection to other symbols. +See comments at definition of N_INDR in ld.c + +4. LD can accumulate sets of related values from all the object files +that are being linked together, and put them into a vector that can +be accessed at run time. Thus, you can arrange for each file to have +initializations to be run when your `main' function sees fit, without +having to know the names of all the files that are linked together. +See comments at definition of N_SETA, etc., in ld.c. |
