Bug 3564 – Rdmd failing to link external C libraries

I try to run D-code with an externally linked C library in this example: ~/dee% dmd test.d -L-lSDL ~/dee% ./test ~/dee% rdmd test.d -L-lSDL /tmp/.rdmd/rdmd-test.d-E6CBF3336CD9625C87A273ACDCCC0CF8/test.d.o: In function `_Dmain': test.d:(.text._Dmain+0x9): undefined reference to `SDL_Init' collect2: ld returned 1 exit status --- errorlevel 1 With dmd it works fine, but with rdmd it doesn't link the library at all. Dry run looks like this: ~/dee% rdmd --dry-run test.d -L-lSDL chdir '.' && dmd -v -o- 'test.d' >test.d.deps dmd -of'/tmp/.rdmd/home/plol/dee/test.d.E6CBF3336CD9625C87A273ACDCCC0CF8' -od'/tmp/.rdmd/rdmd-test.d-E6CBF3336CD9625C87A273ACDCCC0CF8' 'test.d' The code I run is this: extern (C) { int SDL_Init(uint); } enum uint SDL_INIT_EVERYTHING = 0x0000FFFF; void main(char[][] args) { SDL_Init(SDL_INIT_EVERYTHING); }

rdmd's parameter format is: rdmd [RDMD AND DMD OPTIONS]... program [PROGRAM OPTIONS]... The order is important. This works fine: ------------------------ $ cat main.d module main; import theLib; void main() { foo(); } $ cat theLib.d module theLib; import std.stdio; void foo() { writeln("In foo"); } $ dmd theLib.d -lib $ mv theLib.d hide-this-file-and-keep-it-out-of-the-way-theLib.d $ rdmd -LtheLib.a main.d In foo ------------------------ But be aware of this: http://d.puremagic.com/issues/show_bug.cgi?id=4814

There's one more file I forgot to include in my example above: -------------------- $ cat theLib.di module theLib; void foo(); --------------------

Reopening, didn't notice this was regarding linking to C.

I can't reproduce this, seems to be a simple inversion of arguments. Use this: rdmd -L-lsomelib somefile.d NOT rdmd somefile.d -L-lsomelib Trying it with a couple of C libraries does not show any symptoms.
