Trying to compile libobjc with Hans-Boehm GC under MinGW

[Lloyd Dupont]

I donwloaded (from http://www.hpl.hp.com/personal/Hans_Boehm/gc/), build and installed Boehm GC.

 

Now I'm trying to build 'objc.dll'

with

 

make clean

make gc=yes

 

It more or less work but fail at the link stage with that error

 Linking clibrary libobjc ...
c:\MinGW\bin\..\lib\gcc\mingw32\3.4.4\..\..\..\..\mingw32\bin\ld.exe: cannot find -lobjc_gc
collect2: ld returned 1 exit status
make[1]: *** [shared_obj/libobjc.dll.a] Error 1
make: *** [libobjc.all.clibrary.variables] Error 2

 

Any idea what's going on and how to fix it?

Thanks!
