基于 VSCODE 不能进行 debug 查看变量信息 #171

Closed davidxiaozhi closed 1 year ago

davidxiaozhi commented 1 year ago

Xmake 版本

xmake v2.7.6+20230202, A cross-platform build utility based on Lua

操作系统版本和架构

Linux algserver 5.4.0-128-generic xmake-io/xmake#144-Ubuntu SMP Tue Sep 20 11:00:04 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

描述问题

1.VSCODE debug 时选择 xmake 无法 debug

依赖code lldb 已安装

另外我通过xmake 的工作栏 debug 执行代码时会出现 /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by release 模式下没问题,命令行的解决方案是通过把旧的删除掉 ,软连接到conda 的动态库

xmake.lua 已配置 add_includedirs("/App/conda/include")

add_linkdirs("/App/conda/lib")

conda 当中是已经安装 conda install -c conda-forge gxx_linux-64==12.2.0 -y

strings /App/conda/bin/../lib/libstdc++.so.6 | grep GLIBCXX_3.4.29

期待的结果

基于 vscode 能够完成 debug

工程配置

附加信息和错误日志

/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found ,命令行debug已解决,请问是否通过配置使用 conda 里的动态可以解决 vscode debug 未解决

waruqi commented 1 year ago

这个好像跟 xmake 也没啥关系，要么 conda 的问题，要么 codelldb 和 cpptools 插件的问题，xmake-vscode 也仅仅只是透传给它们直接加载调试

另外 conda 库，直接包集成干嘛不用 add_requires("conda::xxx")/add_packages("conda::xxx")

davidxiaozhi commented 1 year ago

@waruqi 这里还没有使用 conda 内部的其他库,当前只是 gcc,未来打算使用, 另外要么 conda 的问题，要么 codelldb 和 cpptools 插件的问题,这个是只我的配置文件有问题么, 结合 xmake 配置 debug 有什么建议,还是直接依据 codelldb 或者 cpptools 的官方要求配置就可以了

waruqi commented 1 year ago

推荐走官方仓库包，插件调试运行，会内置每个包动态加载需要的环境变量信息。比如 LD_LIBRARY_PATH，然后透传给调试器，以及级联依赖支持。。

用 conda 等第三方库，里面的 so 加载，目前没 LD_LIBRARY_PATH 自动设置支持，你得自己外面配置加载环境

调试器走 cpptools/codelldb 都可以，但不管走哪个，xmake 只能送可执行文件路径给它们加载，依赖的 so 库，需要它们去找。。

先确认 xmake run 运行是否正常，xmake run 里面会对 xmake-repo 仓库包自动加载对应环境变量，如果正常，就是 so 的加载路径问题，如果也不正常，自己 ldd 调下。

编译器不用改，走默认 gcc clang 都可以

davidxiaozhi commented 1 year ago

好的, xmake run 运行是没问题的, 基于 conda 的动态库 LD_LIBRARY_PATH 未来确实需要基于环境变量设置一下,提前学到了,我重新 review 以下插件,我怀疑是cpp插件的问题,好了这里同步,也希望其他的小白们可以借鉴

waruqi commented 1 year ago

那就是 LD_LIBRARY_PATH 没设置，目前仅仅 xmake-repo 仓库包，我内部会配置各种 LD_LIBRARY_PATH PATH 等变量，确保运行正常，也会传给调试器，不用额外配置。。

但是第三方包仓库，提供的包信息有限，xmake 并不知道哪些路径需要设置 LD_LIBRARY_PATH 的，所以只能用户自己外面配置。

所以建议尽量用 xmake-repo 里面包

使用 xmake 的时候请教一下通过vscode debug 的时候 launch.json 如何正确配置

下面的如何正确配置

davidxiaozhi commented 1 year ago

看到知乎的录制视频了,借鉴一下 https://www.zhihu.com/question/353722203

davidxiaozhi commented 1 year ago

视频当中,单击 xmake 下方的 debug, 自动就可以 debug ,但是我的 demo 当中不行,是不是多个 target 的原因, 如何调整配置,有一些建议么另外视频当中下面的文件生成, 提示信息如下

waruqi commented 1 year ago

不需要设置 launch.json，装下 codelldb 和 cpptools 插件，然后点下面的调试

davidxiaozhi commented 1 year ago

codelldb 和 cpptools 已安装,并同步到容器内了 codelldb 插件在容器内已同步安装

cpptools 插件

点击下面的调试

弹出设置窗口提示b不能决定 debugger path 需要指定 MIDebuggerPath

@waruqi

waruqi commented 1 year ago

你 gdb 装了么，它提示找不到调试器

https://github.com/xmake-io/xmake-vscode/blob/06a258318c2d32f2f7871130a806a6f889a0eed9/src/debugger.ts#L137

也就是加载调试的时候，vscode 会去调用 gdb 调试的，但是 vscode 没找到 gdb 。。就报错了。。

如果是在容器里面跑，先看下是否装了 gdb，如果装了，再确认下是否具有调试权限。。我记得容器里调试，需要开些权限的，否则 gdb 里面没法断点调试。。

davidxiaozhi commented 1 year ago

之前插件没有同步的时候,xmake 点击debug 启动的是命令行调试,当时我基于命令行是可以的,所以应该是安装过的,我重新安装一下lldb 和 gdb 试试,我也发现是调试器找不到,估计容器被人 kill 过的原因,我重新安装一下看看

waruqi commented 1 year ago

https://github.com/xmake-io/xmake-vscode/blob/06a258318c2d32f2f7871130a806a6f889a0eed9/src/debugger.ts#L28

目前是调用 xmake l find_gdb.lua 去找 gdb 的。。

你可以调下插件里面这个脚本 https://github.com/xmake-io/xmake-vscode/blob/06a258318c2d32f2f7871130a806a6f889a0eed9/assets/find_gdb.lua

也可以清下项目的缓存，强制重新找下。。xmake f -c

davidxiaozhi commented 1 year ago

我 debug 发现是 conda 在借鉴依赖冲突时导致之前的 lldb 和 gdb 消失了导致的,我重新初始化容器后 xmake 编译出现

装下 libstdc++ 或者 libc++ ，linker 确保使用 clang++/g++

你只要不改 ld，默认就是 g++/clang++

没必要设置，想切 clang ，只需要整体切 --toolchain=clang

waruqi log 变更为

带 -v 的 link logs

davidxiaozhi commented 1 year ago

@waruqi 现在是任何一个xmake工程,都不能编译,比如之前基于xmake 创建 c++的默认工程,xmake f -c 后,执行 xmake 编译会出现

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

set_languages("c++17")

--set_optimize("fastest")

add_includedirs("/App/conda/include")

target("hello")
    set_kind("binary")
    add_files("src/*.cpp")

[ 60%]: linking.release magic-person /App/conda/envs/conda_xmake/bin/x86_64-conda-linux-gnu-ld -o buil

为什么你会去用 x86_64-conda-linux-gnu-ld ?

刚说了 linker 走 g++ 或者 clang++

如果自己没配置修改，就检查下 $LD 什么的环境变量，看是否有设置。

waruqi commented 1 year ago

看下 $LD $CC 环境变量设置，有的话，去掉。。或者走 --toolchain=gcc 或者 --toolchain=clang 切下。

davidxiaozhi commented 1 year ago

定位是 conda 的虚拟环境激活设置的 LD

waruqi commented 1 year ago

那就按上面的方式处理下

davidxiaozhi commented 1 year ago

@waruqi 嗯已处理 xmake f --toolchain=clang 比较好使, 但是更新 xmake.lua 后, vscode xmake 插件菜单就会恢复默认,再次基于 vscode切换clang-15 通过 xmake 插件和命令行 build 都会出现 /usr/bin/ld: build/.objs/magic-car/linux/x86_64/release/src/example/01/car/Main.cpp.o:(.data.DW.ref.gxx_personality_v0[DW.ref.gxx_personality_v0]+0x0): undefined reference to `__gxx_personality_v0' clang-15: error: linker command failed with exit code 1 (use -v to see invocation)

ld 由 conda 当中的 ld 变成了系统的 ld (/usr/bin/ld),这里$LD 依然为空, 但是通过命令行再次执行 xmake f --toolchain=clang 就会恢复正常,默认 xmake 选择的并不是 clang

set_toolchains 可以配置到 xmake.lua，或者插件配置里面有个 additionalConfigs 配置参数，可以配到那里

davidxiaozhi commented 1 year ago

重新打开 vscode xmake插件菜单就会恢复默认, xmake 插件重新选择 clang-15 的时候,通过 xmake 插件编译仍然会出现上面的问题,我看日志还是 ld 切换为了非 clang

davidxiaozhi commented 1 year ago

set_toolchains 可以配置到 xmake.lua

set_toolchains 可以配置到 xmake.lua 这个是只针对单个 target 的,针对全局是不是还是上面的命令行更保险

davidxiaozhi commented 1 year ago

@waruqi 其实只要设置成功了就能成功 debug 了,现在,LD 目前没有环境变量,默认死系统的 LD 非 g++ 或者 clang++ 看样需要 debug 一下 xmake ,到时可能还得请教

waruqi commented 1 year ago

你在 root scope 设置，不就全局生效了么，而且插件底下也有专门的 tool bar 可以切 toolchain

davidxiaozhi commented 1 year ago

@waruqi 而且插件底专门的 tool bar 切 toolchain 为 clang15 不好使, ld 没有切换其他的切换过来了, xmake f --toolchain=clang 这个是最好使的

waruqi commented 1 year ago

toolbar 里可以选 clang 的，干嘛要用 clang15呢，就是自动传 --toolchain=clang 一样的效果，跟你命令行设置有啥区别？

而且 set_toolchains 全局切也可以，刚说了。

xmake f --toolchain=clang

之前也说了，插件配置里，可以写死配置的，不用命令敲

或者插件配置里面有个 additionalConfigs 配置参数，可以配到那里

davidxiaozhi commented 1 year ago

@waruqi 我理解错了,我以为 clang15 和 clang 是一样的效果,我测试一下

waruqi commented 1 year ago

clang-15 指的是一些系统上走 apt install clang-15 安装的特定版本 clang 。。编译器 bin 本身文件名就是 /usr/bin/clang-15 这种。。

davidxiaozhi commented 1 year ago

@waruqi 好的总结问题产生的背景基于c++17 编译器 clang 15.0.6 ,clang 15.0.6 是依赖 gcc-12.2.0 ,c++标准库 gxx_linux-64==12.2.0

debug 依赖 codelldb 插件, 基于 conda 升级 clang 会导致 gdb lldb 安装失败不可用,影响debug
默认 ld 问题,xmake 推荐 linker 使用 g++ 或者 clang++ 如果默认获取linker 非以上两个,需要切换整个 toolchain 2.1 xmake f --toolchain=clang 2.2 xmake.lua 内 set_toolchains 全局配置切 2.3 xmake 菜单切换 toolchains 这里需要注意的是选择 clang 非其他的类似 clang-15 的 toolchains,特殊场景除外

新手小白,都可以参考
