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.

Code:
equery d rust

shows you all packages that pull in rust.

Hi mike155,

thanks for your reply! :)

But it is not exactly, what I meant with:

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 ??
