How to use Hans Boehm GC with GNUstep?

[Lloyd Dupont]

I was led to believe that even though it was not well test, it should compile with Boehm GC.

Although I asked many times I had exactly one answer on "how to compile with Boehm GC" and it was:

"make gc=yes"

(and google found nothing at all)

 

 

So I'm trying that today.

 

libobjc issued a few warning and didn't link, but by stripping out a few useless library from the link command make it succeed (I know the final command, thanks to 'make -n').

 

now I'm trying to build libgnustp-base.

I was told I should and, anyway, my program crashed if I simply replace libobjc.

 

so I'm trying to rebuild libgnustep-base

=>

make clean

make gc=yes

 

it doesn't compile at all.

it fails utterly while build GSNextRuntime.m

which is not build in normal mode.

After looking at the GNUmakefile it's because of:

===========

ifneq ($(OBJC_RUNTIME_LIB), gnu)
Additions_OBJC_FILES += GSNextRuntime.m
endif
ifneq ($(FOUNDATION_LIB), gnu)
Additions_OBJC_FILES += GSCompatibility.m
endif
Additions_OBJC_FILES += Unicode.m
===========

eek..... why is 'gc=yes' changing the environment / make variable: OBJC_RUNTIME_LIB ?

looks like a nasty incompatibilities which might break many many files....

 

I tried

find . -name "*make*" -exec grep OBJC_RUNTIME_LIB {} \;

 

but nowehere this variable is set, it's just read....

 

any tips?
