Bug 16546 – ordering of modules matters for pragma(lib) on linux

module ordering on command line (or indirectly via a call to rdmd) shouldn't matter, but on linux it seems the ordering of '-lfoo -lbar' matters when foo depends on bar, one ordering giving undefined symbol errors. what about providing a hook that allows user to postprocess the command line before calling the linker?

clarification: module mod1; pragma(lib,"foo"); module mod2; pragma(lib,"bar"); module main; version(v1){ import mod1; import mod2; } else{ import mod2; import mod1; } rdmd -version=v1 main.d;//ok rdmd main.d;//undefined symbol (when foo depends on bar)

As far as I can tell, I don't think a change in the language is needed. If you wish to link against a library which has a dependency, then specify the dependency in the same module. I.e. if in you example libbar depends on libfoo, change mod2.d to: module mod2; pragma(lib,"foo"); pragma(lib,"bar");
