ninja: error: build.ninja:68: unknown build rule 'cu'

[dddddjent]

Xmake 版本

2.9.4

操作系统版本和架构

Archlinux

描述问题

xmake project -k ninja 生成的build.ninja没有cuda编译相关的rule，不能正常编译
但是直接xmake build可以

期待的结果

ninja能够成功编译

工程配置

xmake create [project_name]
mv src/main.cpp src/main.cu

add_rules("mode.debug", "mode.release")

target("xmake_cuda_ninja_test")
    set_kind("binary")
    add_files("src/*.cu")

附加信息和错误日志

create ok!

Xmake version

2.9.4

Operating system version and architecture

Archlinux

Describe the problem

The build.ninja generated by xmake project -k ninja does not have rules related to cuda compilation and cannot be compiled normally.
But you can directly xmake build

Expected results

ninja can compile successfully

Project configuration

xmake create [project_name]
mv src/main.cpp src/main.cu

add_rules("mode.debug", "mode.release")

target("xmake_cuda_ninja_test")
    set_kind("binary")
    add_files("src/*.cu")

Additional information and error logs

Create OK!

我暂时没有 cuda 环境，你可以自己在这个位置加上 cuda.build 的 rule 试试，然后提个 pr 过来。。

xmake/xmake/plugins/project/ninja/build_ninja.lua

Line 38 in 6295d86

or rulename == "objc.build" or rulename == "objc++.build" then

I don’t have a cuda environment for the time being. You can try adding the cuda.build rule to this location and submit a PR. .

xmake/xmake/plugins/project/ninja/build_ninja.lua

Line 38 in 6295d86

or rulename == "objc.build" or rulename == "objc++.build" then

rule name 很早就加了，所以这里加一行就能编译正常 cuda 代码。不过 devlink 不是基于 batchcmd，目前不太好处理。

The rule name was added very early, so adding one line here can compile normal cuda code. However, devlink is not based on batchcmd and is currently not easy to handle.
