Fyne: Can't run hello world app

[thanhps42]

When I run, it say:

# pkg-config --cflags  -- eina evas ecore-evas ecore-evas ecore-input ecore eina evas ecore-evas ecore-input ecore evas ecore ecore-evas ecore-input evas
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'openssl', required by 'emile', not found
pkg-config: exit status 1

I has been installed EFL.

Thanks.

I also ran into this

Hi, is this on macOS by any chance? I think I know what is going on, let's see if I can update the bootstrap to correctly setup openssl as well

[komuw]

for me, it is on Ubuntu 18.04

[andydotxyz]

I have updated the bootstrap script which may help solve the issue - can you please re-run the bash command and let me know if this changes things?

[andydotxyz]

(it appears to be a bug in the debian packaging info whereby emile does not report that it depends upon openssl, but the development files require it to be present...)

Can you please paste the output of the command line when the bootstrap is running?
Thanks

Hi,

This is confusing - the latest change to bootstrap should have meant that it cannot get directly to "All dependencies installed". I guess some caching could exist.

If you manually install libssl-dev and then re-run bootstrap does it work correctly?

[edelmanjm]

Same issue on macOS 10.13.6. openssl is installed with Homebrew and is up to date.

[andydotxyz]

Hi,

If you run “brew link openssl” does it work?
Do you know where the openssl.pc file is installed to?

[edelmanjm]

Still not working. Looks like it's actually installed using something other than Homebrew. Not sure how or when, but homebrew gives Warning: Refusing to link macOS-provided software: openssl when asking it to create the links.

The file appears to be installed to /usr/local/opt/openssl/lib/pkgconfig/openssl.pc

[andydotxyz]

That makes sense, as macOS has it's own version of some dependencies but lacks some of the developer facilities to discover them..

If you execute the following before launching the go does it work better?

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opt/openssl/lib/pkgconfig

It seems like that should fix things, and if so I think the bootstrap / docs could be updated to fix.

[edelmanjm]

That fixes it! If you want I can submit a PR For that. Should I add that export to my .bash_profile, or is it only needed for the setup script?

Also, not sure if this is related, but I'm getting a different error now when running the Hello Fyne example. It doesn't prevent the application form launching, but it seems like it'd be good to paste. Let me know if I should be opening a separate issue for this.

Hi,

A PR would be great - but as you guessed this is needed every time a Fyne app is built, not just for the setup script.
.bash_profile is a good place to put it I would think - it's a shame that homebrew does not include a command to set this.

The other errors are related to DBus not working by default but that is not a problem.
I have mentioned to the EFL team that it would be better to not continually throw developer errors but we've not got that resolved yet.

[thanhps42]

That makes sense, as macOS has it's own version of some dependencies but lacks some of the developer facilities to discover them..

If you execute the following before launching the go does it work better?

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opt/openssl/lib/pkgconfig

It seems like that should fix things, and if so I think the bootstrap / docs could be updated to fix.

It's work now. Thanks (y)

[edelmanjm]

I've created a fork with the changes, however I can't seem to submit a PR and I keep getting logged out and getting 404 errors on my work. I'm guessing it's something to do with GitHub's incident earlier today, so I'm going to wait until that calms down.

[andydotxyz]

@komuw This has been fixed for macOS users - I don't think the same fix works for Ubuntu though. Did you have the exact same error (Package 'openssl', required by 'emile', not found) or was it just similar?
