I finally got around to installing the new version (with the run-time fix in place). When I precompile EiffelBase, the C code all compiles but the link fails with: /home/eiffel/Eiffel13.11.93542/studio/spec/linux-x86/lib/libwkbench.a(interp.o): In function `interpret': interp.c:(.text+0xd39e): undefined reference to `__divdi3' interp.c:(.text+0xd46c): undefined reference to `__udivdi3' interp.c:(.text+0xd952): undefined reference to `__moddi3' interp.c:(.text+0xdbf4): undefined reference to `__umoddi3' /home/eiffel/Eiffel13.11.93542/studio/spec/linux-x86/lib/libwkbench.a(wmisc.o): In function `eif_sleep': misc.c:(.text+0x266): undefined reference to `__divdi3' misc.c:(.text+0x28b): undefined reference to `__moddi3' Looks like the runtime was compiled with gcc instead of cc. Can you give me a new version? I think I just need the contents of $ISE_EIFFEL/studio/spec/linux-x86/lib where runtime is compiled with Sun cc.
