描述问题

我试图在一个C+rust的项目里使用no_std/nostdlib(可以先忽略C的这部分) 进行编译。 rust项目在独自的rsystem目录下，有自己的xmake.lua。 我使用add_requires("cargo::rsystem", {...}) 为它添加 std = false, main = false 并使用toml管理它的cargo依赖。 这个库应该被编译为静态库并可以被c链接。

遇到的问题首先 rsystem 这个目标似乎会被编译成可执行文件，xmake为它生成的Cargo.toml并不会包含[lib] ，并且xmake会为它会生成一个main.rs（里面似乎还包含一些panic handler之类的东西，但这不应该是我自己添加吗？）而不是lib.rs进行编译。

其次，xmake无法正确安装编译产物，在提示 copy /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/cache/source/target/x86_64-unknown-none/release/deps to /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/934c937479bb4bedb432f28382ca4aaa/lib 之后，复制并没有成功，在目标路径并不存在，尽管源文件的路径确实存在。

仔细看了一下，在installdir.failed/lib 里面是有这些文件的

另外有一个疑问是，我预期的行为是整个项目被cargo原封不动地进行编译，然后和项目的其他部分进行链接，但是似乎xmake会创建一个额外的cargo项目然后只包含我add_files("src/lib.rs")添加的lib.rs？

期待的结果

编译得到一个static library并可以被添加为其它c项目的依赖项（这里没有使用 bindgen，因为我打算手写头文件）

Title: Unable to build no_std rust project

Yangff commented 7 months ago

实际上的话会有两个问题，如果我使用 x86_64-unknown-linux-gnu 作为target，然后在cargo.toml里面加

[profile.release]
panic = "abort"

因为xmake会使用main.rs编译可执行文件，因为找不到 __libc_start_main的符号而失败，尽管在这里就不应该有 __libc_start_main.

然后，如果试图用 x86_64-unknown-none 作为target，在package.lua里面fetch package的时候会因为

    else

        print(system)
        print(self:is_thirdparty())
        print(self:is_cross())
        print(self:plat(), self:arch())
        -- only fetch it from the xmake repository first
        if not fetchinfo and system ~= true and not self:is_thirdparty() then
            fetchinfo = self:_fetch_library({require_version = self:version_str(), external = external, force = opt.force})
            if fetchinfo then
                is_system = self._is_system
            end
        end

        -- fetch it from the system and external package sources (disabled for cross-compilation)
        if not fetchinfo and system ~= false and not self:is_cross() then
            fetchinfo = self:_fetch_library({system = true, require_version = require_ver, external = external, force = opt.force})
            if fetchinfo then
                is_system = true
            end
        end

    end

这里is_cross()会为真，但是这个是cargo的源而不是xmake的package manager所以两个分支都不会执行。

Yangff commented 7 months ago

去掉 is_cross() 的话，在编译实际的rust代码的时候，似乎不会带上arch，导致cargo和rustc使用不同的arch tuple。

Issues-translate-bot commented 7 months ago

If is_cross() is removed, it seems that arch will not be included when compiling the actual rust code, causing cargo and rustc to use different arch tuples.

mentalonigiri commented 7 months ago

I had similar problems with fetch *** failed, and I can tell now it was github server side problem. It is not xmake bug. It is github, probably their web server, drops git clone connection randomly. A little weird workaround is to use git over ssh. You have to create git script somewhere and prepend it to your PATH. Script is here:

#!/bin/bash

cmd=("$@") # Copy original arguments into an array
for i in "${!cmd[@]}"; do
if [[ "${cmd[$i]}" =~ ^https://github.com ]]; then
    cmd[$i]=${cmd[$i]//https:\/\/github.com/ssh:\/\/git@github.com}
fi
done
/bin/git "${cmd[@]}" # Execute the git command with the possibly modified arguments

Basically it changes https://github* to ssh://git@github* . That way your git clone connection is authorized by your ssh key (dont forget to setup ssh key for your github account!). And those weird connection drops stop happening for me.

waruqi commented 6 months ago

遇到的问题首先 rsystem 这个目标似乎会被编译成可执行文件，xmake为它生成的Cargo.toml并不会包含[lib] ，并且xmake会为它会生成一个main.rs（里面似乎还包含一些panic handler之类的东西，但这不应该是我自己添加吗？）而不是lib.rs进行编译。

这个只是个空 wrapper ，仅仅只是为了借助 cargo 拉取到对应的依赖库，而这个编译生成的二进制产物 不会去使用。

其次，xmake无法正确安装编译产物，在提示 copy /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/cache/source/target/x86_64-unknown-none/release/deps to /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/934c937479bb4bedb432f28382ca4aaa/lib 之后，复制并没有成功，在目标路径并不存在，尽管源文件的路径确实存在。

能否给个完整的 project demo ，我调试下

另外有一个疑问是，我预期的行为是整个项目被cargo原封不动地进行编译，然后和项目的其他部分进行链接，但是似乎xmake会创建一个额外的cargo项目然后只包含我add_files("src/lib.rs")添加的lib.rs？

xmake 里 rust 项目不是用 cargo 编译的，是 xmake 自己直接调用 rustc 编译的。。调用 cargo 仅仅只是为了拉依赖库

如果都直接调用 cargo 去编译项目了，那就没 xmake 啥事了，你直接用 cargo 去编译就完事了，没必要去用 xmake

或者可以看下这个 https://docs.rs/xmake/latest/xmake/，在 cargo 里调用 xmake

Issues-translate-bot commented 6 months ago

Bot detected the issue body's language is not English, translate it automatically.

Problems encountered: First, the rsystem target seems to be compiled into an executable file. The Cargo.toml generated by xmake does not contain [lib], and xmake generates a main.rs for it (which seems to also contain Some panic handler stuff, but shouldn't that be something I add myself?) instead of lib.rs for compilation.

This is just an empty wrapper, just to use cargo to pull the corresponding dependent library, and the binary product generated by this compilation will not be used.

Secondly, xmake cannot correctly install the compiled product and prompts copy /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/cache/source/target/x86_64-unknown-none/release/deps to /home/dell/Projects/test-proj/build/.packages/c/cargo_rsystem/latest/934c937479bb4bedb432f28382ca4aaa/lib, the copy does not succeed, the destination path does not exist, although the path to the source file does exist.

Can you give me a complete project demo so I can debug it?

Another question is that the expected behavior is that the entire project is compiled intact by cargo and then linked with other parts of the project, but it seems that xmake will create an additional cargo project and then only include my add_files("src /lib.rs") added lib.rs?

The rust project in xmake is not compiled with cargo, but is compiled by xmake itself directly calling rustc. . Calling cargo is just to pull dependent libraries

If you call cargo directly to compile the project, then there is no need for xmake. You can just use cargo to compile it. There is no need to use xmake.

Or you can take a look at this https://docs.rs/xmake/latest/xmake/ and call xmake in cargo

Yangff commented 6 months ago

能否给个完整的 project demo ，我调试下

我又想了一下应该是编译出来了，x86_64-unknown-none的主要问题可能是x86_64-unknown-none和x86_64-linux-gnu会被xmake认为是两个架构没法链接在一起，等我去看的时候他已经把东西删了。所以就算强行install了之后编译rust项目的时候用的tuple还是错的。

https://github.com/Yangff/xmake_rust_no_std

但是，如果去掉 set_arch，xmake在编译提取依赖的空项目的时候会失败，会提示

  = note: /usr/sbin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.1/../../../../lib/Scrt1.o: in function `_start':

          /usr/sbin/ld: (.text+0x21): undefined reference to `__libc_start_main'
          collect2: error: ld returned 1 exit status

不知道为什么他会尝试链接main，明明我设置了 main = false,

Yangff commented 6 months ago

没必要去用 xmake

rust那边我可以生成正常的.a，主要是为了c/c++那边可以把它链接上，类似cmake那边corrosion的用法。

Issues-translate-bot commented 6 months ago

Bot detected the issue body's language is not English, translate it automatically.

No need to use xmake

I can generate normal .a on the rust side, mainly so that the c/c++ side can link it, similar to the usage of corrosion on the cmake side.

是我这 ructc 版本太低了

应该是，allocator api还是nightly。你可以 在features 里把 "allocator" and "nightly_api" 关掉或者把这些代码都删了随便塞个什么东西给allocator…… 因为用不用这个包不重要，我只是从我自己的项目里复制了一下。 ……不过删了还是有点麻烦，建议还是直接nightly吧

Issues-translate-bot commented 6 months ago

My ructc version is too low

It should be, allocator api or nightly. you can Turn off "allocator" and "nightly_api" in features or delete all these codes... Because it doesn't matter whether you use this package or not, I just copied it from my own project.

Yangff commented 6 months ago

可能要把

#[panic_handler]
#[cfg(not(test))]
fn panic(_info: &core::panic::PanicInfo) -> ! {
    loop {}
}

// rust_eh_personality
#[no_mangle]
#[cfg(not(test))]
extern fn rust_eh_personality() {}

这个加上

Yangff commented 6 months ago

不过就算不加，用了nightly的话我这里也可以进到这一步 linux-no-std:

master分支是演示如果将目标的arch设置成x86_64-unknown-none的情况，在xmake.lua里有 https://github.com/Yangff/xmake_rust_no_std/blob/master/xmake.lua#L2C11-L2C30

不过我不是很确定的一点是无论如何也不应该出现 the lang item is first defined in cratestd`, 因为lib.rs里使用了#![no_std]`..

我试了一下加不加panic函数我这里都是能编译的才对。。

而且不管怎么说我配置的也是main=false

add_requires("cargo::rsystem", {
    configs = {
        std = false,
        main = false,
        cargo_toml = path.join(os.projectdir(), "rsystem", "Cargo.toml"),
    }
})

不应该出现main吧？

Issues-translate-bot commented 6 months ago

Bot detected the issue body's language is not English, translate it automatically.

And no matter what, I configured it with main=false

add_requires("cargo::rsystem", {
configs = {
std = false,
main = false,
cargo_toml = path.join(os.projectdir(), "rsystem", "Cargo.toml"),
}
})

Main shouldn't appear, right?

master 我这也可以了

加上add_rcflags("--target", "x86_64-unknown-none", {force = true}) 后可以链接（这个需要加上panic函数

target 这个我加上了，你可以再试试 https://github.com/xmake-io/xmake/pull/5164

xmake update -s github:xmake-io/xmake#rust

panic 这个需要用户手动自己加上吧，那这边就不管了。。我加上后也能编译

不过我这 macOS 上 link 的时候，还有一个 error 正在看。

linux-no-std分支在configure的时候失败

我单独拎出来用 cargo build 也一样失败，因为你配置了 no main ，所以内部那个 stub rs 里面，自动加了 

#![no_main]
$ cargo build --release -vv
defaultlibs"
  = note: ld: Undefined symbols:
            _main, referenced from:
                <initial-undefines>
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

没有 main 就 link 失败了。。所以，我刚提 cargo deps 的那个 stub wrapper 改成 staticlib 了，这样里面就不会走到 link ，反正也只是为了提取 cargo 下载的依赖用。。

https://github.com/xmake-io/xmake/pull/5164

再试试，至少 main link 那个问题，应该能过掉了。

mater可以正常编译了

linux-no-std那边还需要加上 add_rcflags("-C", "panic=abort", {force = true})。 对于一般使用cargo定义的项目来说这是在Cargo.toml里定义的，因为xmake实际上只是提取依赖的话，在xmake里手动添加这个好像也是合理的。

还有一个 error 正在看

看起来c项目的target和rust的target不一致，链接的时候选择的target是 -target x86_64-unknown-none-apple-macos14.0 (我猜是在set_arch之后强行拼接了mac的target后缀 -apple-macos14.0)，而rust是 x86_64-unknown-none 。 之所以我 set_arch 写 x86_64-unknown-none 而不是 x86_64 是因为rust需要的是前者，如果只写 x86_64 的话传递给rust的target会只有 x86_64, 这个会被rust无视掉。

warning: the arch "x86_64" is NOT a valid target triple, will be IGNORED and may cause compilation errors, please check it again
warning: add -v for getting more warnings ..

不过LLVM的triple太乱了，rust的更乱，感觉这里除了一坨if下来没啥特别好的拼接方法其实。

arch 拼错这个问题，主要是你这 set_arch 全局配置导致的，会对 test target 也生效，但是 test target 里面只有 .c 文件，属于 c 项目，走的 xcode toolchain ，这个时候设置的 arch 应该得用默认的 x86_64 ，而不是 rust 那个 x86_64-unknown-none

你只能单独对 rust 那个 target ，和它的 package 配置 x86_64-unknown-none

add_requires("cargo::rsystem", {
    arch = "x86_64-unknown-none",
    configs = {
        std = false,
        main = false,
        cargo_toml = path.join(os.projectdir(), "rsystem", "Cargo.toml"),
    }
})

target("rsystem")
    set_kind("static")
    add_files("src/lib.rs")
    set_values("rust.cratetype", "staticlib")
    add_packages("cargo::rsystem")
    set_arch("x86_64-unknown-none")

这样，arch 就不会拼错了，但是我这那个 error 还不是这个 arch 导致，问题还是存在

可以，只是要自己加上这个-C panic=abort

一般如果整个项目都是 no_std 的且目标是 x86_64-unknown-linux-gnu 这种情况， panic=abort 是要加的。因为没有std就没有unwind，默认的panic使用 unwind 就无法工作。但是，对于 x86_64-unknown-none 这样的目标默认的panic就是abort所以没有问题，所以master直接就过了。

这里的问题是，cargo.toml里面的定义只是对crate而言的，也就是说crate是no_std而项目本身链接std是完全可能的（一些库用不到std的东西就可以加上这个）。所以应该是没没办法简单根据crate的情况来决定是不是要加这行。

Yes, you just need to add this -C panic=abort yourself

Generally, if the entire project is no_std and the target is x86_64-unknown-linux-gnu, panic=abort should be added. Because there is no unwind without std, the default panic cannot work using unwind. However, for targets like x86_64-unknown-none, the default panic is abort, so there is no problem, so the master can pass it directly.

The problem here is that the definition in cargo.toml is only for crate, which means that the crate is no_std and it is entirely possible for the project itself to link to std (some libraries can add this if they do not use std). So there should be no way to simply decide whether to add this line based on the crate situation.

既然默认也是 abort ，那我就全局加了。。你再试试那个 patch ，看看还有啥问题，没得话，我先 merge 了

Yangff commented 6 months ago

默认也是 abort

啊不是的， x86_64-unknown-none 这种默认是abort的不需要加也不会有问题。只有 x86_64-unknown-linux-gnu 这种默认是 unwind的需要在no_std的情况下加。

但是如果只是根据说cargo包是no std就说整个项目也是no std好像是不大对劲的。。但也不好说，毕竟xmake这里似乎就是把这个cargo包当成是项目本身的cargo.toml来用那好像又没问题。。反正我是不大确定这里到底是咋回事了（

Yangff commented 6 months ago

你再试试那个 patch

这个patch是能用了，不过是否加panic的条件我觉得可以考虑一下，或者单独给一个配置项？至少正常的项目是不应该加这个的，全加上应该会坏事…… 只有真正的no_std项目需要这个（不包括那些只是某个包需要no_std的，比如会不会有人add_requires哪个crate的时候拉进来一个no_std的包）.

Since the default is also abort, I will add it globally. . You can try that patch again and see if there are any problems. If it doesn't work, I'll merge it first.

This patch can be used, but I think we can consider whether to add panic conditions, or provide a separate configuration item?

The default is also abort

Ah, no, x86_64-unknown-none is aborted by default. There is no need to add it and there will be no problem. Only x86_64-unknown-linux-gnu, which defaults to unwind, needs to be added in the case of no_std.

But it seems wrong to say that the entire project is also no std just based on the cargo package being no std. . But it’s hard to say. After all, xmake seems to use this cargo package as the cargo.toml of the project itself, so there seems to be no problem. . Anyway, I’m not quite sure what’s going on here (

关键是这边没法判断当前项目是否 no_std，只有某个包有这个配置，target 里面判断不出来，除非根据 arch 判断是否交叉编译，如果交叉编译就加。。

再不行，就只能用户自己 add_rcflags 自己加了

Issues-translate-bot commented 6 months ago

This patch can be used, but I think we can consider whether to add panic conditions, or provide a separate configuration item? At least normal projects shouldn't add this. Adding it all should be bad... Only real no_std projects need this (excluding those that just require no_std for a certain package. For example, will someone pull it in when adding_requires which crate a no_std package).

The key is that there is no way to determine whether the current project is no_std. Only a certain package has this configuration. It cannot be determined in the target unless it is judged according to arch whether to cross-compile. If it is cross-compiled, add it. .

If it doesn't work, the user can only add it by himself using add_rcflags.

Yangff commented 6 months ago

如果交叉编译就加

尴尬的是交叉编译的那个情况反而不用加就行了，因为走的是-none的triple，rustc自动就是abort。

我觉得在target这个范围内好像没有特别好的条件来判断。。

The embarrassing thing is that in the case of cross compilation, there is no need to add it, because using the -none triple, rustc automatically aborts.
