Hi,<div><br></div><div>I haven't installed XCode 4 yet, but the&nbsp;crt1.10.5.o is the c runtime file defining the symbol "start" which any program will be linked with being the programs real entry point.</div><div><br></div><div>Disassembling "crt1.10.5.o" (for Leopard) and "crt1.10.6.o" (for Snow Leopard) reveals the very same code for the symbol "start", but</div><div><meta charset="utf-8">"crt1.10.5.o" additionally defines "dyld_stub_binding_helper" and "__dyld_func_lookup".</div><div><br></div><div>I think I read that XCode 4 is snow leopard+ only, therefore I guess&nbsp;"crt1.10.5.o" was deleted when you've install Xcode 4.</div><div><br></div><div>Maybe a symbolic link "ln -s&nbsp;crt1.10.6.o&nbsp;crt1.10.5.o" in /usr/lib shall do just fine, but I will keep a copy of "crt1.10.5.o" before upgrading to Xcode 4 just in case and report any findings.</div><div><br></div><div>- Steffen</div><meta charset="utf-8"><meta charset="utf-8"><meta charset="utf-8"><meta charset="utf-8"><meta charset="utf-8">
