使用 Conan 构建 libjpeg/9d 时引导 makefile 片段时出错
Error bootstrapping makefile fragments while building libjpeg/9d with Conan
几天来我一直在尝试安装 OpenCV with Conan（在 Windows 10 上）。但是，安装在构建 libjpeg/9d 依赖项时失败。
柯南简介：
[settings]
arch=x86_64
arch_build=x86_64
build_type=Debug
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=8
os=Windows
os_build=Windows
[options]
[build_requires]
[env]
使用的命令：
conan install .. --profile vslamprofile --build=missing
与错误相关的日志部分：

我发现有几个人遇到了类似的错误（虽然不是在安装 OpenCV 时），但我还没有找到任何解决方案。

libjpeg 库很可能无法使用 MinGW 工具套件中的 autotools and/or makefile 进行编译。即使它是 Windows 的 gcc，也不是所有代码都可以在平台之间完全移植，那些自动工具或 Makefile 可能会做一些在 [=25= 中不正确的平台假设].
一般来说，Visual Studio 工具链（MSBuild，cl.exe）在 Windows 平台上得到社区更好的支持，可以被认为是默认的 to-go，尤其是如今 Visual Studio 社区版完全免费。
ConanCenter are also typically (and most of them, the ones created from the conan-center-index repo) 中的软件包是用 Visual Studio（多个版本）构建和测试的，因此预计支持会比 MinGW 好得多。
您可能对 Makefile.am 进行了修改，导致 autoreconf and/or configure 失败。 运行,
rm -f config.h* configure
清理，然后运行,
autoreconf; ./configure
重新配置。当然，如果您在此期间没有撤消对您的 Makefile.am 的假定的、冒犯性的更改，您最终将处于相同的位置。
几天来我一直在尝试安装 OpenCV with Conan（在 Windows 10 上）。但是，安装在构建 libjpeg/9d 依赖项时失败。

我发现有几个人遇到了类似的错误（虽然不是在安装 OpenCV 时），但我还没有找到任何解决方案。

libjpeg 库很可能无法使用 MinGW 工具套件中的 autotools and/or makefile 进行编译。即使它是 Windows 的 gcc，也不是所有代码都可以在平台之间完全移植，那些自动工具或 Makefile 可能会做一些在 [=25= 中不正确的平台假设].
一般来说，Visual Studio 工具链（MSBuild，cl.exe）在 Windows 平台上得到社区更好的支持，可以被认为是默认的 to-go，尤其是如今 Visual Studio 社区版完全免费。
ConanCenter are also typically (and most of them, the ones created from the conan-center-index repo) 中的软件包是用 Visual Studio（多个版本）构建和测试的，因此预计支持会比 MinGW 好得多。
您可能对 Makefile.am 进行了修改，导致 autoreconf and/or configure 失败。 运行,
rm -f config.h* configure
清理，然后运行,
autoreconf; ./configure
重新配置。当然，如果您在此期间没有撤消对您的 Makefile.am 的假定的、冒犯性的更改，您最终将处于相同的位置。
