Vitis AIの構造を勉強してみる（4日目）

cmkake問題を片付けよう。

cmake問題をどうする？

Ubuntu 20.04.1LTSでcmakeのバージョンは？

$ which cmake
/home/hidemi/.local/bin/cmake
$ cmake --version
cmake version 3.18.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

おぉ？

バージョンは3.18.2で3.5より上なのでいいんだけど、なんで.localの下にあるんだろう？

いやいや、ちょっと待って。

ライブラリはZynqMPSoC上で実行されるものだからローカルホスト向けにビルドしちゃいけないよね。

PetaLinuxの環境を整えてみよう。

$ source /opt/pkg/petalinux/2020.2/settings.sh 
PetaLinux environment set to '/disk/opt/pkg/petalinux/2020.2'

さて、cmakeしたらどうなるかな？

$ cmake ..
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

うむ、エラーである。

project(ProjectName)ってなんやねん？

それとXilinxVersionってなんやねん？

いまいちわからない、明日にしよう。
