[lldb-dev] about the error:unable to restore file position to 0x00000ab0 for section __DWARF.__debug_info

[DuYvonne]

Hi, GregThanks very much for your time.The flag -flimit-debug-info does not solve my problem.I checked the .o files for my project that every .o file is very large (among 3.5MB to 6MB). I think this is the cause for my problem. I included too many header files in the precompile headers. There seems no way to let me strip the dup symbols when generate .dSYM files.  The only option I find is  -feliminate-dwarf2-dups which works only for dwarf2.The concern to me is that even I switch to clang, can this problem be solved? > Subject: Re: [lldb-dev] about the error:unable to restore file position to 0x00000ab0 for section __DWARF.__debug_info
