When manually calling the linker, which libraries should be linked with a d object file? If I run dmd with the -v option on Mac OS X, I notice dmd issues the following linker command: gcc test.o -o test -m32 -Xlinker -L/Library/Compilers/dmd2/osx/bin/../lib -lphobos2 -lpthread -lm which includes library phobos2 but not druntime. I've made D for Xcode link both phobos2 and druntime in the final executable; this cause no problem on Mac OS X 10.6 (Snow Leopard) but I have a user on 10.5 (Leopard) who gets duplicate symbols in druntime and phobos2 because of this. So now I wonder, is druntime included into the phobos2 library? Is this how it should be? -- Michel Fortin michel.fortin michelf.com http://michelf.com/

Here is the line (200) from the Phobos makefile that builds the file libphobos2.a: $(DMD) $(DFLAGS) -lib -of$ $(DRUNTIME) $(D_FILES) $(OBJS) The variable $(DRUNTIME) contains the path to libdruntime.a. If it is removed, Phobos still compiles just fine, so I suspect it shouldn't be there. -Lars

If it was a dynamic lib, then we need to address it. What I find odd is that libdruntime.a is in the lib subdir even though it's never used. -Steve
