I have a program written in C++ and C that exports C functions. I
have been able to create a dynamic library, using:
gcc -dynamiclib ofile1.o ofile2.o -o libfile.dylib -shared-libgcc -
lstdc++-static
such that I may simply compile and link a vanilla C program without
having to link to the C++ runtime library. For example:
gcc -O3 my_test.c -o my_test -L../libdir -lfile
NOT
gcc -O3 my_test.c -o my_test -L../libdir -lfile -shared-libgcc -lstdc
++-static
The reason I need a static C++ library that can be used by C programs
is this: I have a C++ library that will be embedded in the runtime
system of a program language compiler that produces assembly code
through gcc (not g++). I cannot change the linker flags the compiler
passes to gcc, just for a problem on OS X and I cannot require every
developer who uses the system to bundle the dynamic library
(libfile.dylib) with every program they ship.
I have also created a static library using libtool:
libtool -static -o libfile.a -s -arch_only ppc *.o
but when I want to link to that library, I have to append -shared-
libgcc -lstdc++-static (that is, I have to link to the C++ runtime
library) every time.
I cannot create a static library using:
ld -static ...
because ld (or ld called through "gcc -static") produces errors:
(1) if I specify only -fno-weak, I get an error for:
lazy symbol pointers (.non_lazy_symbol_pointer),
(2) if I specify -fno-weak AND -mdynamic-no-pic, I get an error for:
symbol_stubs
Does anyone here have experience with this sort of thing?
Thanks in advance for any help you can give.
Peter
