[gs-devel] Cross-compiling Ghostscript, linker issues, Mac OS X

[Gerben Wierda]

I am trying to cross compile ghostscript:
	- compile system: Mac OS X 10.5
	- target system: Mac OS X 10.4

What I have done:

In a master makefile I have set

SDK=/Developer/SDKs/MacOSX10.4u.sdk
SDKCFLAGS= -isysroot ${SDK}
SDKLDFLAGS= -isysroot ${SDK} -Wl,-syslibroot,${SDK}

and I run from that same Makefile

			./configure --without-x && make XCFLAGS="${SDKCFLAGS}" XLDFLAGS="$ 
{SDKLDFLAGS}"

This works up to a point. The CFLAGS gets changed and a compile to  
object looks like (e.g.)

gcc  -DHAVE_MKSTEMP -DHAVE_HYPOT   -DHAVE_FONTCONFIG -O2 -Wall - 
Wstrict-prototypes -Wundef -Wmissing-declarations -Wmissing-prototypes  
-Wwrite-strings -Wno-strict-aliasing -fno-builtin -fno-common - 
DHAVE_STDINT_H -DGX_COLOR_INDEX_TYPE="unsigned long long"  -isysroot / 
Developer/SDKs/MacOSX10.4u.sdk -I./obj -I./src  -o ./obj/gxipixel.o - 
c ./src/gxipixel.c

But the final link has no XLDFLAGS. obj/ldt.tr contains:

gcc -o ./bin/gs ./obj/gsromfs1.o ./obj/gs.o ./obj/gp_getnv.o \
./obj/gp_unix.o \
./obj/gp_unifs.o \
[etc.]

unixlink.mak contains:
$(GS_XE): $(ld_tr) $(ECHOGS_XE) $(XE_ALL) $(PSOBJ)gsromfs$ 
(COMPILE_INITS).$(OBJ)
         $(ECHOGS_XE) -w $(ldt_tr) -n - $(CCLD) $(LDFLAGS) -o $(GS_XE)
         $(ECHOGS_XE) -a $(ldt_tr) -n -s $(PSOBJ)gsromfs$ 
(COMPILE_INITS).$(OBJ) $(PSOBJ)gs.$(OBJ) -s
         cat $(ld_tr) >>$(ldt_tr)
         $(ECHOGS_XE) -a $(ldt_tr) -s - $(EXTRALIBS) $(STDLIBS)

Hence, I expect LDFLAGS to be there before -o ./bin/gs but it is not  
there in ldt.tr.

I am stymied. Any clues what goes wrong here?

Thanks,

G

PS. Trying to give these cross compiling flags to configure fails  
miserably (configure is unable to link anything).
