Output dsymutil: invalid option

MarioAleo

Hello,

I'm starting using Xamarin, I've build an simple app on Windows and everything was fine, but now that't I'm trying to use on Mac, I just can't build the app or debbug on my device.
When I try to emulate, it works fine, but when I try to emulate it i get the following error:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Error: Tool exited with code: 1. Output: dsymutil: invalid option -- z
NAME
dsymutil -- manipulate archived DWARF debug symbol files.

SYNOPSIS
dsymutil [--arch=ARCH] [--out=path] exe_path

DESCRIPTION
dsymutil links the DWARF debug information found in the object files
for an executable exe_path by using debug symbols information contained in
its symbol table.

A list of flags and their descriptions:

--arch=ARCH
    Link DWARF debug information only for specified CPU architecture
    types.  Architectures may be specified by name or by number. When
    using this option, an error will be returned if any architectures
    can not be properly linked.  This option can be specified multiple
    times, once for each desired architecture.  All cpu architectures
    will be linked by default and any architectures that can't be
    properly linked will not cause dsymutil to return an error as long
    as at least one architecture was able to link successfully.

-h
--help
    Display the help documentation for this command.

-f
--flat
    Produce a flat dSYM file (not a bundle).

-o path
--out=path
    Specifies an alternate path to place the .dSYM bundle. The default
    dSYM bundle path is created by appending '.dSYM' to the executable
    name.

--oso-prepend-path=path
    Specifies a path to prepend to all debug symbol object file paths.

-s
--symtab
    Dumps the symbol table found in executable or object file(s) and
    exits.

-t n
--threads=n
    Specifies the maximum number (n) of simultaneous threads to use
    when linking multiple architectures.

-v
--version
    Display the current version and build date of the dsymutil
    binary.

--verbose
    Display verbose information when linking.

You need to update your Command Line Tools.

I assume you're using Mavericks (since I believe this was fixed in Yosemite), in which case you can update the Command Line Tools in Xcode's preferences.

MarioAleo

I'm using Yosemite and also I'm using xcode 6 with it's last command line tools.
Anyway, thanks for the answer.

MarioAleo

I'm still with problem, I've already tried to reinstall the Command Line Tool, reinstall XCode and to reinstall both, but the problem still there.

Finally get rid of the error.
Xamarin was using a dsymutil on /usr/bin/ that was out of date, here is the way to fix it:

• Install the newest Command Line Tool, and "cd" to it's directory, probable at /Library/Developer/CommandLineTools/.

• Inside it you'll find the dsymutil at /usr/bin/dsymutil, then copy it to /usr/bin/.

• Now try to build the app on Xamarin.

Remember to verify if everything is up to date and if it's all from compatible versions.

I already tried, but not work,
