cmakeModules

This repository contains helpful CMake modules for a variety of Xilinx build flows.

Current release

The current release is meant to be used with the Xilinx Vitis 2022.1 tools.

There are two main toolchains:

(1) Vitis cross compiler toolchain (toolchain_vitis_crosscomp_arm.cmake)

(2) Clang cross compiler toolchain (toolchain_clang_crosscomp_arm.cmake)

The toolchains are invoked as most standard toolchains but with two additionally defined parameters (Arch, Sysroot).

$cmake .. -DCMAKE_TOOLCHAIN_FILE=<path to cmakeModules>/<target toolchain file> -DArch=<arm32|arm64> -DSysroot=<absoluate path to sysroot folder>

In both cases, the sysroot folder can be the default Vitis sysroot, a Petalinux generated sysroot or a standard Ubuntu-based sysroot like those built by PYNQ. In the case when you're working with more custom sysroots like Vitis or Petalinux, you should use the toolchain toolchain_clang_crosscomp_arm_petalinux.cmake which provides additional guidance to find the necessary libraries. Note that this file may need to be edited depending if you're using 2022.1 or an older tool version. See the toolchain_clang_crosscomp_arm_petalinux.cmake header for more information.

cmakemodules's Issues

Compatible with Vitis 2020.2

Hi,

sorry if this is a dumb question, but will these Scripts be working with Vitis 2020.2? The commits are about 2 years old.
I am just getting up to speed working with the tools, but as I am very used to having CMake for all other C++ projects.

I'd prefer setting up projects with CMake, and then opt-in on Simulation and Hardware synthesis. Is this even possible?
Is there any documentation?
I feel that a CMake approach will be the only reasonable one, when integrating with more complex projects.

Sorry again for what seems like a beginner question.

FindLibXAIE has hard coded paths

It should support LibXAIE_DIR and/or LibXAIE_ROOT.

FindVitis fails with 2021.1

It seems that the key files in the include directory aren't there anymore... (hls_stream.h)

Update FindVitis for AIE essentials release

• remove checks for chess mk and DSP lib
• verify FindVitis works on native Ubuntu and WSL

unsafe for cross-compilation

I got

$ cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=/usr/lib/cmake/xilinx/toolchain_clang_crosscomp_arm.cmake

Perhaps CMAKE_FIND_ROOT_PATH_MODE_PROGRAM, CMAKE_FIND_ROOT_PATH_MODE_LIBRARY, CMAKE_FIND_ROOT_PATH_MODE_INCLUDE, CMAKE_FIND_ROOT_PATH_MODE_PACKAGE should be set correctly.
