You could create yourself a Linux VM on your MAC (Install the RDK and copy the Files from there). The ADK/RDK "Installer" is 64Bit only - you would hav to install to a 64Bit OS. It has both File Parts for 64Bit and 32Bit (vcomponents).
Most VPS are 64Bits. So a 64Bit WebApp would make installing the required dependencys easier. Because intslling the 32Bit dependencys on a 64Bit OS can be a pain in the a.. (for Xojo Apps). You should check out Xojo System Requirements. PS: Point is: if Youre Server-OS is CentO7 (and Up) or Ubuntu 14.04 (and UP) you should Create a 64Bit Application else for Example for CentOS 6 or Ubuntu 12.04 you can only Create 32Bit Apps (because they don't have the required Library VERSIONS for Xojo Apps (librarys are there but the wrong Version)
And for the Deployment of Apps with Valentina you should checkout: The Reference Link
like the others say. RPM or DEB ar the same just target Different Linux Distributions.
you could deploy the vcomponents and vresources folder a a sub folder in your web app.
The Question remains if the WebApp would even run. Most (Shared) Hosting Companies dont have all the required librarys on the Servers witch would have to be installed on the server to run the Xojo WebApp.
Most People use a Dedicated Server for this - in witch case you can install all the librarys you need.
You could try Asking your Hosting Company if they would install the required librarys - in witch case they should also be able too install the Valentina ADK/RDK.
v4rb.so is not enough, it is necessary to have also vcomponents folder.
It should be copied to the application folder.
vcomponents for linux are distributed in the DEB and RPM packages, so usually it is necessary to have linux to get it.
However, there is an option to do it on OS X.
Don't you have linux to extract vcomponents?
I don't remember having our hosting company install anything. Can't I just include something in the application directory? I just looked in the Directory of the only app that is using it and there is a file named: v4rb.so? Is that not the Valentina Report adk?
