Check system for user installed Linux dependencies #1180

leaanthony · 2022-02-23T20:43:34Z

Attempts to discover the dependencies if not installed via the package manager.
The library discovery code is untested!

Better, but still not correct...

Dependency	Package Name		Status		Version
----------	------------		------		-------
*docker		docker.io		Installed	20.10.5+dfsg1
gcc		build-essential		Installed	10.2.1
libgtk-3	libgtk-3-dev		Available	3.24.24-4
libwebkit	libwebkit2gtk-4.0-dev	Available	2.34.6-1~deb11u1
npm		npm			Installed	8.5.0
pkg-config	pkg-config		Installed	0.29.2

However, after unset LANG I get:

Dependency	Package Name		Status		Version
----------	------------		------		-------
*docker		docker.io		Installed	20.10.5+dfsg1-1+deb11u1
gcc		build-essential		Installed	12.9
libgtk-3	libgtk-3-dev		Installed	3.24.24-4
libwebkit	libwebkit2gtk-4.0-dev	Installed	2.34.6-1~deb11u1
npm		npm			Installed	8.5.0
pkg-config	pkg-config		Installed	0.29.2-1

Here is the output for version v2.0.0-beta.31 after unset LANG:

Dependency	Package Name		Status		Version
----------	------------		------		-------
*docker		docker.io		Installed	20.10.5+dfsg1-1+deb11u1
gcc		build-essential		Installed	12.9
libgtk-3	libgtk-3-dev		Installed	3.24.24-4
libwebkit	libwebkit2gtk-4.0-dev	Installed	2.34.6-1~deb11u1
npm		npm			Available	7.5.2+ds-2
pkg-config	pkg-config		Installed	0.29.2-1

I have installed all mention packages through the package manager, except npm, which is too old.
So the fix is a partial fix.

Why would LANG change things? All I'm doing for the libraries is running pkg-config and checking if it finds the cflags for the given library

pebbe · 2022-02-24T17:37:52Z

~ apt list build-essential
Bezig met oplijsten... Klaar
build-essential/stable,now 12.9 amd64 [geïnstalleerd]
build-essential/stable 12.9 i386

~ unset LANG

~ apt list build-essential
Listing... Done
build-essential/stable,now 12.9 amd64 [installed]
build-essential/stable 12.9 i386

Nice catch @pebbe - I think we can fix this by setting LANG before shelling. Thanks for taking time to test 👍

leaanthony · 2022-02-26T00:06:11Z

@pebbe - I've added a change that will attempt to set LANG for the call. I'm unable to test this locally. Is there a more robust way to detect packages are installed?

pebbe · 2022-02-26T01:17:01Z

Perhaps this?

dpkg-query -W -f '${status}\t${package}\t${version}\n' docker* build-* libgtk* libwebkit* npm pkg-config

v2/internal/system/system_linux.go

+			checker := checkerFunctions[dep.Name]
+			if checker != nil {
+				checkLocallyInstalled(checker, dep)
+				continue


is continue really needed here?

also the if on line 48 what protects us against?

I am afraid that this fix wont cut it

Do we think this can be merged?

leaanthony · 2022-03-15T09:25:10Z

Merging this as it appears to be better than what we have.
