VSTlib

Install VSTlib, a separate package from VST, as coq-vst-lib through the Coq Platform or from the coq-released opam archive.

VSTlib release 2.12

VSTlib: VST-verified C library for VST-verified clients

These program modules, in the form of Verified Software Units, may be linked with client-module code (at the .c/.o level) and proofs (at the .v level). This release of VSTlib is expected to be compatible with VST 2.11.1 and VST 2.12.

VST version 2.12

The best way to install VST 2.12 is through the Coq Platform release 2023.03, or more recent.

New in this release:

• entailer!! tactic that does not put so many propositions above the line, compared to entailer!. See the end of the entailer! chapter in the manual.
• VSTlib, a new library of Verified Software Units; currently has interface to malloc/free library, math library, threads and locks libraries.
• Compatible with Coq 8.16 and 8.17, and with CompCert 3.12.

VST version 2.11.1

The best way to install VST 2.11.1 is through the Coq Platform release 2022.09.1.

VST version 2.9

VST 2.9 is compatible with Coq 8.13, 8.14, or 8.15; and with CompCert 3.10.

The simplest way to install VST is to install the Coq Platform.

The Coq Platform 2022.01 already contains VST 2.9 in the 8.15~beta1 package pick.
If you install Coq Platform via the "coq_platform_make.sh" script, it will ask you which package pick to install.

By mid-2022 you can expect that a non-beta 2022 Coq Platform will contain VST 2.9 (for Coq 8.15 and CompCert 3.10).

If you do not want to install a beta version of Coq Platform, you can also install the 8.14~2022.01 package pick via "coq_platform_make.sh". This package pick contains VST 2.8, but you can change this by first installing Coq Platform without CompCert and VST (it will ask) and then running "opam install coq-vst.2.9".

VST version 2.8

The simplest way to install VST is to install the Coq Platform. A Coq Platform release in approximately August 2021 will include VST 2.8.

Until then, the best way to install VST 2.8 is through opam: from the coq-released repository, install package coq-vst, version 2.8.

One method of doing that is:

1. Install the Coq Platform 2021.02.1 release using the "Compiling from Sources via opam" method; in that process unselect (do not install) CompCert and VST.
2. Then do opam update; opam install coq-vst which will install the latest CompCert and VST.

VST version 2.7

VST 2.7, released December 2020, compatible with Coq 8.12 or 8.13 and with CompCert 3.7 or 3.8.
