Re: Using D static library from C
You need to link the druntime too, I think.

Re: Using D static library from C
You can create a static library from one or more .o files using ar, if that helps (unless I've failed to understand the question). ar r libtest.a test.o should do the job.

I just remeberd linking d with gcc needs a few libs -lpthread -lc -lm and possiby more though I use gdc I don't know what dmd links by default try to make an object file with gcc and link with dmd

I don't have trouble creating a static library with dmd, I have trouble figuring out how to link it with C using gcc.

So additional libs does not solve anything. The trouble is linking a static lib without causing a segfault.

Re: Using D static library from C
I found that if I told dmd rather than gcc to do the linking that everything just magically worked. In other words: gcc -c cstuff.c dmd -c dstuff.d dmd cstuff.o dstuff.o I presume that dmd would be similarly smart with static libraries.

To get around phobos2 being linked twice and still have a static lib suitable for gcc I'm trying this now: dmd -c test.d ar r libtest.a test.o gcc main.c -ltest -L. -lphobos2 -otest It works with this small test project. I'll try to integrate this into bigger project now.

That works! Thanks. So is dmd linking to shared/different phobos2 by default or something?
