We are currently trying to compile a barebox with the git version of ptxdist and the git version of the OSELAS generic Toolchain for powerpc. Also the current 2011.07.0 release of barebox. We are having some problems during the build, which I think are a result of some changes in gcc's optimizations (since 4.4.something). GCC uses some functions on the ppc platform to optimze the size of the resulting binary, which are only present in the libgcc.a. The compile stage works fine up tp the last linker step: CC arch/ppc/lib/time.o AS arch/ppc/lib/misc.o CC arch/ppc/lib/ppclinux.o CC arch/ppc/lib/board_data.o LD arch/ppc/lib/built-in.o LD barebox common/built-in.o: In function `mapset': hush.c:(.text.mapset+0x44): undefined reference to `_restgpr_30_x' common/built-in.o: In function `syntax_err': hush.c:(.text.syntax_err+0x34): undefined reference to `_restgpr_30_x' common/built-in.o: In function `done_command': hush.c:(.text.done_command+0x94): undefined reference to `_restgpr_29_x' common/built-in.o: In function `done_pipe': hush.c:(.text.done_pipe+0x5c): undefined reference to `_restgpr_29_x' common/built-in.o: In function `is_assignment': hush.c:(.text.is_assignment+0x8c): undefined reference to `_restgpr_27_x' common/built-in.o: In function `b_addchr': hush.c:(.text.b_addchr+0x8c): undefined reference to `_restgpr_28_x' common/built-in.o: In function `b_addqchr': hush.c:(.text.b_addqchr+0x78): undefined reference to `_restgpr_29_x' ... This goes on for a few pages. As far as I can see, the possibilities I have here, is to either integrate the missing functions out of the gcc sources into barebox, or make barebox link with libgcc, which seems surprisingly difficult, due to the unfamiliar (to me) build process. A simple LDFLAGS_barebox+=-l.. -L.. did not help here. Am I right with this assumption, or am I missing something else here? Any help would really be appreciated.
