Well, you could try this untested patch... The sh-linux-tdep.c parts bring it in line with other Linux ports, but are not specifically important for your problem. The configure.tgt parts fix the fact that "sh4-linux-uclibc" was not recognized as a Linux system. -- Daniel Jacobowitz CodeSourcery 2008-02-25 Daniel Jacobowitz * configure.tgt (sh-*-linux*): Match sh*. Add glibc-tdep.o. * sh-linux-tdep.c (sh_linux_init_abi): Use glibc_skip_solib_resolver and svr4_fetch_objfile_link_map. * Makefile.in (sh-linux-tdep.o): Update.
