Hi ,

I am using gcc4.0 amd the MacOSXSDK 10.4u for the intel version and gcc3.3 and the 10.3.9 sdk for the ppc version of the build .

I then use lipo to create a universal binary and then archive them into a static library .

The above two steps are done on an intel mac 10.4

I create quite a many static llibraries from the above build .

I now intend to use these universal static libraries to create executables on ppc and when I try to link these libraries on ppc using gcc 3.3 , I get a lot many errors

ld: ../src/liblmgr.a(wurzl34.o) r_type field of relocation entry 3751 in section (__TEXT,__text) invalid

ld: ../src/liblmgr.a(wurzl34.o) stray relocation PPC_RELOC_PAIR entry (3752) in section (__TEXT,__text) .

I also tried creating a thin library from the universal version of the library and using this tin library to link with the other object files/libraries to create an executable . But even that seems to fail with the same error.

The compiler flags and other details that I have set for the build are

ARCH_i386 = -arch i386

SDKROOT_i386 = $(shell $(GPLATARGS_CMD) -sdk_i386)

CFLAGS_i386 = $(INCFLAGS) $(DEBUGFLAG) $(XTRACFLAG) -isysroot $(SDKROOT_i386) $(THREADFLAG) $(ACTFLAGS) $(ARCH_i386)

CC_i386 = gcc-4.0

ARCH_ppc = -arch ppc

SDKROOT_ppc = $(shell $(GPLATARGS_CMD) -sdk_ppc)

CFLAGS_ppc = $(INCFLAGS) $(DEBUGFLAG) $(XTRACFLAG) $(THREADFLAG) $(ACTFLAGS) -isystem $(SDKROOT_ppc) $(ARCH_ppc)

CC_ppc = gcc-3.3

$(CC_i386) -c $(CFLAGS_i386) -S $< -o $*i.s

$(CC_i386) -c $(CFLAGS_i386) $*i.s -o $*i.o

$(CC_ppc) -c $(CFLAGS_ppc) -S $< -o $*p.s

$(CC_ppc) -c $(CFLAGS_ppc) $*p.s -o $*p.o

lipo -create -o $@ $*i.o $*p.o

rm $*p.s $*i.s $*i.o $*p.o

I have searched for all the help I could get from the existing archives and forums ,but in vain .

Can any one help me on this . Please

Shweta.
