Description
Loads the zbar library.Our Barcode.Scan function uses the open source zbar library. Since this library is licensed under LGPL, we can't embed it within the plugin, but you can ship it with your solution, either as a file you install with the plugin or as a file you store in a container and then export to a temp folder.
If you have a libzbar64-0.dll in the FileMaker application folder, you can simply pass "libzbar64-0.dll" as path to load on Windows.
We have libraries for you here:
https://www.monkeybreadsoftware.com/filemaker/files/Libs/
With MBS Plugin v13.2, we implemented automatic loading of a zbar library if you don't call Bacode.LoadLibrary yourself. We look for libzbar64-0.dll on Windows, libzbar.so.0 on Linux and libzbar.dylib on macOS.
If you have trouble with DLLs not loading on Windows, please check if you have new Visual Studio Runtime libraries installed. If you need more than one DLL, please use Process.SetDllDirectory to point to the folder to find the DLL files.
Examples
Load the zbar library on macOS:
MBS( "Barcode.LoadLibrary"; "/Users/cs/Desktop/zbar/libzbar.0.dylib" )
Load the zbar library on Linux:
MBS( "Barcode.LoadLibrary"; "/usr/lib/x86_64-linux-gnu/libzbar.so.0" )
// needs to install package on Linux:
// sudo apt-get install libzbar0
Load on various operation systems:
If [ MBS("IsWindows") ]
# you may need to download zbar from our Libs folder or get your own
# our copy of the library has a dependency, so we load libiconv first
Set Variable [ $path ; Value: "C:\Users\Christian\Desktop\libiconv.dll" ]
Set Variable [ $r ; Value: MBS( "Process.LoadLibrary"; $Path ) ]
# now we can load zbar dll
Set Variable [ $path ; Value: "C:\Users\Christian\Desktop\libzbar64-0.dll" ]
Else If [ MBS("isMacOS") ]
# you may need to download zbar from our Libs folder or get your own
Set Variable [ $path ; Value: "/Users/cs/Desktop/zbar/libzbar.0.dylib" ]
Else If [ MBS("isLinux") ]
# you may need to install first: sudo apt-get install libzbar0
Set Variable [ $path ; Value: "/usr/lib/x86_64-linux-gnu/libzbar.so.0" ]
Else
Show Custom Dialog [ "Unsupported platform" ; "No library coded for this platform or no MBS Plugin installed." ]
Halt Script
End If
#
# load zbar
Set Variable [ $r ; Value: MBS("Barcode.LoadLibrary"; $path) ]
If [ MBS("IsError") ]
Show Custom Dialog [ "Failed to load library" ; $r ]
End If
