Error bootstrapping makefile fragments while building libjpeg/9d with Conan - c++

Question

I have been trying for several days to install OpenCV with Conan (on Windows 10). However, the installation is failing on building the libjpeg/9d dependency.
Conan profile:
[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]
The used command:
conan install .. --profile vslamprofile --build=missing
The part of the logs related to the error:
libjpeg/9d: configure: creating ./config.status
libjpeg/9d: config.status: creating Makefile
libjpeg/9d: config.status: creating libjpeg.pc
libjpeg/9d: config.status: creating jconfig.h

libjpeg/9d: for automatic dependency tracking. Try re-running configure with the
libjpeg/9d: '--disable-dependency-tracking' option to at least be able to build
libjpeg/9d: the package (albeit without support for automatic dependency tracking).

I have found several people with the similar error (not while installing OpenCV though) but I have not managed to find any solution.

Answer 1

You likely made a modification to a Makefile.am that caused autoreconf and/or configure to fail. Run,
rm -f config.h* configure
to clean up, then run,
autoreconf; ./configure
to reconfigure. Of course, if you haven't undone the assumed, offending change to your Makefile.am in the meantime, you're going to end up in the same spot.

Answer 2

It is very possible that the libjpeg library doesn't compile with autotools and/or makefiles in the MinGW tool suite. Even if it is a gcc for Windows, it is not like all the code is fully portable between platforms, and those autotools or Makefiles might do some assumptions of platform that are not correct in Windows.
In general, the Visual Studio toolchain (MSBuild, cl.exe) is better supported in Windows platforms by the community, could be considered the default to-go, especially nowadays that the Visual Studio Community editions are completely free.
The packages in ConanCenter are also typically (and most of them, the ones created from the conan-center-index repo) built and tested with Visual Studio (several versions), so the support is expected to be much better than the one for MinGW.
