xrepo search zlib error

[ItaloFan]

我刚开始学习使用xmake，在尝试xmake的包管理时出现了问题

环境

• windows11
• 通过msys2安装的gcc
• 未安装msvc

基本情况

通过设置xmake f --toolchain=gcc能成功编译运行hello world项目，但包管理功能无法正常使用

问题描述

首先是xrepo search zlib -vD和xrepo install zlib -vD都会出现同样的问题：

error: checking for platform ... windows
checking for architecture ... x64
checking for Microsoft Visual Studio (x64) version ... no
error: target(working): toolchain not found!

然后我尝试在hello world工程中添加zlib：

add_rules("mode.debug", "mode.release")
set_toolchains("gcc")
add_requires("zlib")
target("hello")
    set_kind("binary")
    add_files("src/*.cc")
    add_packages("zlib")

运行xmake -vD出现问题，完整log：

似乎是有一个基础库文件没有找到？

xrepo install 没指定平台，默认 Windows，而你没装 msvc 工具链所以报错了

#include_next <stdlib.h>

这个是经典问题了，自行谷歌

[waruqi]

通过设置xmake f --toolchain=gcc能成功编译运行hello world项目，但包管理功能无法正常使用

默认 windows 平台，要用包管理，是绑定 msvc 的，不支持切 gcc

要么你在 msys2下，切到 mingw 平台用 gcc

xmake f -p mingw

好的，感谢回答！
