hi all

i've successfully compiled phobos master with gmake on freebsd. (make fails, i've no clue at all as to why)

how do i compile my project now against my local phobos with dub? with plain dmd?

i tried (in dub.sdl):
- full path to new libphobos.so with -defaultlib to dflags
- full path to new libphobos.so to lflags

i checked with ldd and saw the original libphobos.so was used. my current workaround is copying mine to /usr/lib.

thanks in advanced.

Hello, what you want to do is certainly possible but... I'd rather build a full custom dmd+runtime+phobos with its own sc.conf file Why ?
- Easier to invoke dub w/ the option --compiler=path.
- The custom DMD will alsways use the right phobos (when not using dub).

try changing the dmd.conf file that is next to the dmd binary. My current one looks like

[Environment]
DFLAGS=-I~/d/druntime/import -I~/d/import -I~/d/phobos -L-L/Users/nicholaswilson/d/lib/

just change the -I and -L-L flags to the appropriate locations. or use the -conf switch (-conf=/path/to/newdmd.conf)

While you are linking with the phobos you compiled yourself with -defaultlib, ldd (and your binary) will pickup the one available in one of the paths configured for the run-time shared library loader.

To actually make use of the phobos you compiled you also need to set the rpath.

```
-L-rpath=/path/to/phobos
```

Or use phobos as a static library.
