Problems running RV-Match?

We list below some possible issues occurring when using RV-Match and ways to address them. For any unlisted issue you might experience, or for any questions or suggestions, please contact us at the RV Support Center.

Java 8 is required

If you get installation errors or errors when calling kcc, make sure that you run Java 8 or higher. We tested RV-Match with Oracle Java 8 JDK, but the JRE should be sufficient.

Program does not terminate

Due to the complex analyses performed, both kcc and the kcc-compiled program are orders of magnitude slower than gcc and the gcc-compiled program. If waiting longer or getting a faster machine is not possible, then try to minimize your program and/or its input. For example, it may be a good idea to run unit-tests, or to execute each function separately.

[Windows] Editing programs

You can either execute existing C programs, or write new ones using your favorite editor or IDE from Windows itself. The RV-Match terminal opens in your home directory under the MSYS2 installation, which should be at C:/RV-Match/msys/home. The MSYS environment behaves exactly like Windows Powershell or cmd. In case you want to install a text editor under MSYS2 itself, you can do with something like:

pacman -S nano vim

You can also use Windows text-editors from the RV-Match terminal by referring to their executables (they must be on the Windows PATH, accessible from Windows cmd, and MSYS2 must be restarted after adding them to the path):

notepad [file]
C:/Program Files (x86)/Notepad++/notepad++.exe [file]
(or notepad++ [file] with notepad on the Windows PATH)

[Windows] Installing Additional Packages

The RV-Match terminal uses MSYS2. The default MSYS2 environment for running RV-Match comes with the Pacman package manager, which can be used for installing or upgrading the software packages available to this environment. This includes installing additional libraries, compilers, or dependencies. A guide on installing packages in MSYS2 is here:

[Windows] Kerberos

MSYS2 comes installed by default with Kerberos, which includes an executable named kcc, same like our tool. We have renamed this program for convenience to avoid conflicts on the path to /usr/bin/kcc_kerberos.exe. If you find that this causes any issues, you can rename the file back to kcc.exe to restore default settings, and access the RV-Match kcc using its alias kclang.
