Missing environment variables for "briefcase dev" run

[NilsRG]

Describe the bug

After following the setup description at beeware/docs/tutorial/tutorial-1.rst exactly, I get two errors about missing folders. I made it work by adding these lines to the activate script:

PKG_CONFIG_PATH='/usr/lib/x86_64-linux-gnu/pkgconfig':'/usr/share/pkgconfig':'/usr/share/pkgconfig':$PKG_CONFIG_PATH
export PKG_CONFIG_PATH

I don't know if that's the right way to do it, so I am not going to fork that page and make a fix (for now).

Log files before and after attached.

Steps to reproduce

1. Go to 'beeware-tutorial/helloworld'
2. Run 'briefcase dev'
3. Scroll down to 'Installing build dependencies: finished with status 'error''
4. See error

Expected behavior

Expected behaviour is what happens in the last log file...

Thanks for the report; can you please clarify what operating system you're using? I think you've provided a uname string... but it's not at all clear what actual distribution that is. It seems to suggest Ubuntu... but it's not obvious what release of Ubuntu it is.

[NilsRG]

Sure! LSB Version: core-11.2ubuntu1-noarch:printing-11.2ubuntu1-noarch:security-11.2ubuntu1-noarch Distributor ID: Ubuntu Description: Ubuntu 22.10 Release: 22.10 Codename: kinetic

Thanks for that clarification.

This seems like you might be missing something in your local system configuration (and - admittedly, this might be because we've missed a pre-requisite in our tutorial).

Can you confirm:

1. If your system has pkg-config installed
2. Whether:

pkg-config --libs glib-2.0

produces valid output (something like -lglib2.0) or an error, without the environment configuration you mention above?

[NilsRG]

pkg-config --libs glib-2.0 Package glib-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `glib-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'glib-2.0' found The above mentioned file seem to be here: locate glib-2.0.pc /usr/lib/x86_64-linux-gnu/pkgconfig/glib-2.0.pc However using sudo, I get this result: sudo pkg-config --libs glib-2.0 [sudo] password for nils: -lglib-2.0 This is all done outside the venv environment, so "env | grep PKG_CONFIG_PATH" returns nothing.

Thanks - I've never seen pkg-config provide different results depending on whether it's run with admin credentials. Is there any possibility that your local shell config is overriding (or ignoring) system default configurations? Have you got a non-default shell? Anything else of note that isn't a "Ubuntu Kinetic default system install"?

[NilsRG]

I have personally done nothing to change it afaik. It may be slightly special because it has Linux pre-installed by System76: sudo lshw nils-sys76 description: Desktop Computer product: Sable (All) vendor: System76, Inc. version: sabl4 serial: System Serial Number width: 64 bits capabilities: smbios-2.7 dmi-2.7 smp vsyscall32 They install quite a few tools as indicated here: [image: image.png] I don't want to add a lot of info you don't need, but if you have commands you want me to run and send the results of, then feel free to tell me. However, if this is a problem only for me then it's fine if you want to close this issue, after all I have a nice fix because of how your error messages are so verbose and helpful.

Looks to me like the picture never got through. I'll attach it here.

[freakboy3742]

Hrm - this is definitely odd. If you create a fresh user account on your machine, does that new user inherit this oddity, or does pkg-config work there without the environment variable?

[freakboy3742]

Tagging @Firstyear because he expressed an interest in the haunting of pkg-config in this case :-)

[Firstyear]

Thanks @freakboy3742 I'm installing a VM to have a look at this.

[Firstyear]

Okay, I've setup a ubuntu kinetic machine but I was unable to reproduce. @NilsRG Can you provide me the output of the following commands all run as your user - I will indicate inline when sudo is needed.

env
pkg-config --libs glib-2.0
sudo pkg-config --libs glib-2.0
sudo env
sudo -i pkg-config --libs glib-2.0
sudo -i env
sudo -s pkg-config --libs glib-2.0
sudo -s env
sudo dpkg-query -L pkg-config

That will help give me some better ideas on where to follow from here because currently "out of box" I can't reproduce.
