 Posted: Wed Feb 17, 2021 3:31 pm Post subject: How to get the most complete depandency graph (reverse)? |
 |
|
Hi,
I have installed Gentoo (64bit) on my Raspberry Pi 4 and there are a few libraries and application,
which need A LOT OF TIME to build on this tiny computer: For example: rust....14 hours.
And it will be triggered quite often for the time it will take to build.
If rust is needed by application, which I dont need or can be replaced with other more lightweighted
one...I would be happy.
But when I do a emerge -cvp --deep --tree I only get
virtiual/rust as dependancy
I can repeat this step by step...and I am still not knowing, whether I catched all dependancies.
Is there as way to get a full depedancy tree, which show me exactly what will happen, if I will
remove rust from my Raspberry Pi 4....in one go?
Cheers!

Moved from Installing Gentoo to Gentoo on ARM.

Hi mike155,
thanks for your reply! 
But it is not exactly, what I meant with:
| Quote: | "Is there as way to get a full depedancy tree, which show me exactly what will happen, if I will
remove rust from my Raspberry Pi 4....in one go?" |
For example...from my | Code: | Raspi:localhost:/root>equery d rust
* These packages depend on rust:
dev-lang/rust-1.50.0 (system-bootstrap ? =dev-lang/rust-1.49*)
(system-bootstrap ? =dev-lang/rust-1.50*)
dev-lang/spidermonkey-78.7.1 (>=virtual/rust-1.41.0)
gnome-base/librsvg-2.50.3 (>=virtual/rust-1.40[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?])
virtual/rust-1.50.0 (~dev-lang/rust-1.50.0[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?])

This says, that (beside other tings) spidermonkey will no longer work....but it does not show, what depends on spidermonkey...
Is there a way to show, what will happen, if I will remove dev-lang/rust from my raspi ... with all its consequences ?
Cheers!

Rust is not in @system set, so removing it shouldn't prevent system from booting. If you want to try, you can make backup of it using quickpkg [1], unmerge it[2], check what are consequences of it and emerge it from backup[3].
[1] quickpkg dev-lang/rust
[2] emerge --unmerge dev-lang/rust
[3] emerge --usepkgonly dev-lang/rust |

This might be what you want: | Code: | | emerge -cvp <packagename> |
-c is an option to "safely" check if a package can be removed (safely meaning don't remove if something depends on it).
-p and -v are pretend and verbose. verbose is required to show you what packages are installed that require <packagename>.

There is a rust-bin that can be used.
Saves the compiling of it.
14 hours seem long, got your governor setup ?? |
