    How I Fixed my “DYLD shared region unnest for map”

    Countless people have had this kind of thing appear in their dmesg output:

    9/15/09 9:15:45 AM	kernel	Safari (map: 0x103f070c) triggered DYLD shared region unnest for map: 0x103f070c, region 0x7fff82c00000->0x7fff82e00000. While not abnormal for debuggers, this increases system memory footprint until the target exits.

    System Events (map: 0x7697ae4) triggered DYLD shared region unnest for map: 0x7697ae4, region 0x7fff85e00000->0x7fff86000000. While not abnormal for debuggers, this increases system memory footprint until the target exits.

    27/02/2010 14:28:11	kernel	Problem Reporter (map: 0x550de18) triggered DYLD shared region unnest for map: 0x550de18, region 0x7fff83600000->0x7fff83800000. While not abnormal for debuggers, this increases system memory footprint until the target exits.

    I fixed mine by doing the following:

    • uninstalling MacFUSE
    • uninstalling SIMBL
    • going through /Library and deleting any leftover SIMBL or MacFUSE files (and removing the MacFUSE.prefPane too)
    • safe reboot (press and hold the shift key)
    • unloading all vmware and parallels modules listed in kextstat
    • deleting ConnectUSB.kext, Pvsnet.kext, hypervisor.kext, vmmain.kext
    • deleting /Library/Application Support/VMware Fusion
    • getting rid of Parallels and VMware applications (I used VirtualBox now)
    • rebooting

    Happy Mac.

    SSHKeychain on Snow Leopard

    I am an avid user of MacPorts, but it seems some things are broken with Snow Leopard. In particular it seems one cannot build SSHKeychain:

    [~]% sudo port install SSHKeychain
--->  Computing dependencies for SSHKeychain
--->  Fetching SSHKeychain
--->  Verifying checksum(s) for SSHKeychain
--->  Extracting SSHKeychain
--->  Applying patches to SSHKeychain

Error: Target org.macports.build returned: shell command "cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_SSHKeychain/work/0.8.2" && xcodebuild  -target "SSHKeychain" -configuration Deployment build OBJROOT=build/ SYMROOT=build/ MACOSX_DEPLOYMENT_TARGET=10.6 ARCHS=x86_64 SDKROOT= ARCHS=i386" returned error 1
Command output:

** BUILD FAILED **


Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to get complete output.

    To fix this, I simply changed “10.4u” and “10.4” on lines 922 and 924 to “10.5” in the xcodeproj file:

    /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_SSHKeychain/work/0.8.2/SSHKeychain.xcodeproj/project.pbxproj

	  	CC39D6380921118A00FE3BC5 /* Development */ = {
                        isa = XCBuildConfiguration;
	           	buildSettings = {
				ARCHS = (
                                	ppc,
		                        i386,
		                );
		                MACOSX_DEPLOYMENT_TARGET_i386 = 10.5;
		                MACOSX_DEPLOYMENT_TARGET_ppc = 10.3;
		                SDKROOT_i386 = /Developer/SDKs/MacOSX10.5.sdk;
		                SDKROOT_ppc = /Developer/SDKs/MacOSX10.3.9.sdk;
		        };
		        name = Development;
		};

    Also further down on lines 936 and 938:

    /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_SSHKeychain/work/0.8.2/SSHKeychain.xcodeproj/project.pbxproj

		CC39D6390921118A00FE3BC5 /* Deployment */ = {
		        isa = XCBuildConfiguration;
		        buildSettings = {
		                ARCHS = (
                                        ppc,
                                        i386,
				);
                                MACOSX_DEPLOYMENT_TARGET_i386 = 10.5;
				MACOSX_DEPLOYMENT_TARGET_ppc = 10.3;
				SDKROOT_i386 = /Developer/SDKs/MacOSX10.5.sdk;
				SDKROOT_ppc = /Developer/SDKs/MacOSX10.3.9.sdk;
			};
                        name = Deployment;
		};

    …and then…

    [~]% sudo port install SSHKeychain
--->  Computing dependencies for SSHKeychain
--->  Building SSHKeychain
--->  Staging SSHKeychain into destroot
--->  Installing SSHKeychain @0.8.2_0
--->  Activating SSHKeychain @0.8.2_0
--->  Cleaning SSHKeychain

    Alternatively, if you wish to just download it, it is available at http://fs.maz.nu/sshkeychain-0.8.2-sl.app.zip.
