[Dwarf-Discuss] Read an .axf file on windows with LibDwarf
Hello, I've seen a lot of webpages to have an idea of what the libdwarf library can do, but I can't find the way to compile it in windows. The reason to do this, is that I want to read and understand an .axf file in my C# program that I'm developing in Visual Studio 10 in Windows (I can use VS15 too). I don't need to debug anything, I only want read an .axf file, so if there is a way to do this, please I want to know it, and how to do it. Thank you, Ane. ___ Dwarf-Discuss mailing list Dwarf-Discuss@lists.dwarfstd.org http://lists.dwarfstd.org/listinfo.cgi/dwarf-discuss-dwarfstd.org

I've tried a few libraries (libdwarf, libelf, examples in VC for both of them, libelfin in c++) and none of them can I compile correctly in windows (it doesn't matter if there was in VS15 / VS10 / as a makefile project with MinGW or normal project / just MinGW in command window ... ). I've just finded another library in C# "ElfSharp" and it seems to be good for reading my .axf file, but I'm looking for decode the DWARF sections. If anyone could help me, I'm all ears. Thanks for the info anyway. Ane. ___ Dwarf-Discuss mailing list Dwarf-Discuss@lists.dwarfstd.org http://lists.dwarfstd.org/listinfo.cgi/dwarf-discuss-dwarfstd.org

I want to do everything in Windows 7, and as far as I understood about LLVM, is for Unix Systems. I don't need the compiler to go faster, I need just compiling the source code, or at least, find some code which has no dependency of Unix libraries. Maybe I didn't understand your idea of doing it, so if it is so, please could you explain it to me again? Did you mean this about LLVM http://llvm.org/docs/GettingStartedVS.html ? Rigth now I'm looking for DWARF info in this library http://elfsharp.hellsgate.pl/examples.shtml , and I just read a section content but all of them are bytes and I need to read them as a dwarf info (and I'm thinking how to decode that part). If I haven't explained it better, please let me know.

I've tried almost everything, also I tried to compile the library on visual studio with mingw's make but it doesn't compile correctly. I think my last option is to read the .axf file through readelf (binutils) as an .exe and get the output to handle it on the C# program. I would like not to need more programs to do this, because the C# program can be developed on multiple computers.
