Command line tool to dump Windows DLL version?

Question

I need a command line tool to dump standard Windows DLL version info so I can process it by means of a bash script (Cygwin).

As a Java developer I am not very used to Microsoft development tools (though I have a little bit of experience with Microsoft Visual Embedded C++ 4.0 and Microsoft Visual Basic 6.0).

The appropriate tool seems to be mt.exe, as stated on SO. However the only chance I have found to get this little application is to download a 1.29 GB ISO of the Windows SDK for Windows Server 2008 and .NET Framework. I can not believe this is the only way to do it.

I have also found a little application on the Internet called PEView, but it displays too much (and useless in my case) information and it is not a command line application.

Standard objdump bundled inside Cygwin can also dump some information about the DLL files, but I can not see the option to dump DLL version. Note that MajorImageVersion, MinorImageVersion and other fields dumped by this tool (with -p option) are not related to own DLL version.

Any alternatives about what to do? Maybe I missed some important objdump option? Is mt.exe my only choice? If this is the case, is it possible to get it separately from Windows SDK?

Answer 1

You can also look at filever.exe, which can be downloaded as part of the Windows XP SP2 Support Tools package - only 4.7MB of download.

The listdlls tools from Systernals might do the job: http://technet.microsoft.com/en-us/sysinternals/bb896656.aspx

listdlls -v -d mylib.dll

This function returns the ntfs Windows file details for any file using Cygwin bash (actual r-click-properties-info) to the term

Pass the files path to finfo(), can be unix path, dos path, relative or absolute. The file is converted into an absolute nix path, then checked to see if it is in-fact a regular/existing file. Then converted into an absolute windows path and sent to "wmic". Then magic, you have windows file details right in the terminal. Uses: cygwin, cygpath, sed, and awk. Needs Windows WMI "wmic.exe" to be operational. The output is corrected for easy...

$ finfo notepad.exe
$ finfo "C:\windows\system32\notepad.exe" 
$ finfo /cygdrive/c/Windows/System32/notepad.exe 
$ finfo "/cygdrive/c/Program Files/notepad.exe"
$ finfo ../notepad.exe

finfo() {
    [[ -e "$(cygpath -wa "$@")" ]] || { echo "bad-file"; return 1; }
    echo "$(wmic datafile where name=\""$(echo "$(cygpath -wa "$@")" | sed 's/\\/\\\\/g')"\" get /value)" |\
    sed 's/\r//g;s/^M$//;/^$/d' | awk -F"=" '{print $1"=""\033[1m"$2"\033[0m" }'
}

Using Powershell it is possible to get just the Version string, i.e. 2.3.4 from any dll or exe with the following command

(Get-Item "C:\program files\OpenVPN\bin\openvpn.exe").VersionInfo.ProductVersion

Tested on Windows 10

Answer 5

or you can build one yourself. Open VS, create a new console application. Create a simple project with no ATL or MFC support, leave the stdafx option checked but do not check 'empty project' and call it VersionInfo.

You'll get a simple project with 2 files: VersionInfo.cpp and VersionInfo.h

Open the cpp file and paste the following into it, then compile. You'll be able to run it, first argument is the full filename, it'll print out "Product: 5.6.7.8 File: 1.2.3.4" based on the Version resource block. If there's no version resource it'll return -1, otherwise 0.

Compiles to an 8k binary using the dll CRT, 60k with everything linked statically (set in the C++ options, change "Code Generation page, Runtime options" to "/MT")

HTH.

PS. If you don't want to use Visual Studio, it'll still compile using any c++ compiler (fingers crossed), but you'll almost certainly have to change the #pragma - just specify that lib in the linker settings instead, the pragma's just a shorthand to automatically link with that library.

    if (!GetFileVersionInfo(argv[1], handle, size, versionInfo))
    {
        delete[] versionInfo;
        return -1;
    }
    // we have version information
    UINT    len = 0;
    VS_FIXEDFILEINFO*   vsfi = NULL;
    VerQueryValue(versionInfo, L"\\", (void**)&vsfi, &len);
