Hi


1. Does the existence of these files imply that libuuid-devel was actually added to MinGW, just not as a separate package?

/usr/x86_64-w64-mingw32/sys-root/mingw/lib/libuuid.a
This one is in mingw-crt
/usr/x86_64-w64-mingw32/sys-root/mingw/include/uuids.h
This one is in mingw-headers

2. In order to overcome this issue I tried to look on the Fedora's native uuid.pc and adopt it inside of the container:

I believe ones shipped by mingw-crt and mingw-headers are basically these https://docs.microsoft.com/en-us/windows/win32/directshow/time-format-guids

They are not related to libuuid.


3. May I ask you to add a separate mingw package for libuuid-devel (with pkg-config file uuid.pc)?

This is one I was experimenting with a while back: https://smani.fedorapeople.org/mingw-libuuid-1.0.3-1.gita29bf0f.fc32.src.rpm

Feel free to use it as a base and submit if for review if it suits your needs.

PS: I've opened Fedora's native /usr/include/linux/uuid.h from libuuid-devel and it looks quite Linux specific...

Here is what I've found regarding porting uuid to windows:

https://trac.xapian.org/ticket/303 <https://trac.xapian.org/ticket/303>

see this (and other patches there):
https://trac.xapian.org/attachment/ticket/303/windows_uuid.patch <https://trac.xapian.org/attachment/ticket/303/windows_uuid.patch>


Can this help to create uuid for mingw?

Thank you!

    Hello,

    I try to create a CI/CD pipeline that would allow to automatically
    cross-compile gImageReader's GTK interface for Windows. Here is
    the Dockerfile in my fork:
    
https://github.com/AvtechScientific/gImageReader/blob/master/packaging/win32/Dockerfile
    
<https://github.com/AvtechScientific/gImageReader/blob/master/packaging/win32/Dockerfile>
    . To build it, one needs to run: `sudo docker build -t
    gimagereader_buildenv packaging/win32`, to build GTK UI run `sudo
    docker run -v $PWD:/workspace gimagereader_buildenv
    packaging/win32/makeinstaller.sh x86_64 gtk`.

    I was able to make some progress but now I'm stuck with `uuid`.
    Here is CMake's error: Checking for module 'uuid' --   No package
    'uuid' found. Full error output: https://paste.debian.net/1201327/
    <https://paste.debian.net/1201327/> If I run `find / -name
    "*uuid*"` inside of the container it looks like uuid is there and
    here is what I get: https://paste.debian.net/1201326/
    <https://paste.debian.net/1201326/> .

    prefix=/usr/x86_64-w64-mingw32/sys-root/mingw
    exec_prefix=/usr/x86_64-w64-mingw32/sys-root/mingw
    libdir=/usr/x86_64-w64-mingw32/sys-root/mingw/lib
    includedir=/usr/x86_64-w64-mingw32/sys-root/mingw/include

    Name: uuid
    Description: Universally unique id library
    Version: 2.37.0
    Requires:
    Cflags: -I${includedir}/
    Libs: -L${libdir} -luuid

    I'm not sure it is correct, but CMake accepted it so far...

    Does this file looks OK to you?

    Thank you in advance!
