My question

I’m trying to build my own package that requires the qt/5.13.2 package. I followed the Creating Packages Tutorial and managed to get it working without any requirements.
I then added the requires = "qt/5.13.2@bincrafters/stable" line to my conanfile.py. So the conanfile.py now looks like this:

from conans import ConanFile, CMake, tools

class MypackageConan(ConanFile):
    name = "my_package"
    version = "0.0.1"
    license = "<Put the package license here>"
    url = "<Package recipe repository url here, for issues about the package>"
    description = "<Description of Hello here>"
    settings = "os", "compiler", "build_type", "arch"
    options = {"shared": [True, False]}
    default_options = {"shared": False}
    requires = "qt/5.13.2@bincrafters/stable"
    generators = "cmake"

    def configure(self):
        # I don't need GUI support for this project
        self.options["qt"].GUI = False
        self.options["qt"].widgets = False
        self.options["openssl].with_asm = False
...

The rest of the file is just the standard contents produced by conan new.

Now, when I try to test my package by running conan create . demo/testing --build, I get the following error:

I researched a bit and found that I can add a build requirement to my package by adding a corresponding line to the conanfile.py. So I added the following

    requires = "qt/5.13.2@bincrafters/stable"
    build_requires = "msys2_installer/latest@bincrafters/stable" # added this line
    generators = "cmake"

The logs indicate that msys2 is now a build requirement but for some reason libpq still does not recognize it.

I finally managed to get libpq compiled by adding the build requirement not to the conanfile.py but to my conan profile. There I can explicitly specify that msys2 is a build requirement of libpq:

...
[build_requires]
libpq/11.5: msys2_installer/latest@bincrafters/stable
...

I tried to do this in the conanfile.py, as well, but that gave me the following error:

ERROR: The reference has too many '/'

However, libpq is not the only package where I need to explicitly specify the build requirement. openssl/1.1.1d (also required by qt) and nasm:1.24 (required by openssl) are also affected by this. So the only way I managed to get the complete build working was to specify the build requirements explicitly in my conan profile:

[build_requires]
libpq/11.5: msys2_installer/latest@bincrafters/stable
openssl/1.1.1d: msys2_installer/latest@bincrafters/stable
nasm/2.14: msys2_installer/latest@bincrafters/stable

Am I doing something wrong regarding build requirements in the conanfile.py or is it not intended to specify them in the same way as in a conan profile? Is there another way how I can specify build requirements I’m not yet aware of?
I hope, I included all of the necessary information. If not, just let me know and I’ll add anything that’s missing.

you could put this in your profile:

[build_requires]
msys2/20190524

so that msys2 build requirement is applied to all the packages. That would be a workaround until libpq, openssl and nasm recipe declare the build_requirement when MinGW is used

Ok, so this works for me now. When I just add msys2/20190524 as a general build requirement in my profile, as you suggested above, it gets applied to all packages just as one would expect. I must have had a corrupted 7zip package from a previous time when I tried to build it from sources. Removing the package from the local cache and running conan create again, finally solved the issue.

Thanks again for all your help with this 😄

So the problem is still existing? I mean buid_requires only works in profile.
