Hi,

I'm currently working on a class project with the purpose to install QMC2 & QT on gentoo, then MAME. I'm quite lost on how to do this, & i just started working on Gentoo / linux some months ago...so i'm a real noob !
Does someone has some tips to help me ? I followed the instructions on Wikis & some other topics, but as i said, i'm lost, & can't seem to install both QMC2 & QT.

Excuse me for any mistakes, i'm a french guy

Thanks for any future answer !

There is no wiki needed though.
QT is a dependancy of QMC2.

On Gentoo it is as easy as "emerge qmc2"

So my next question would be "where did this leave you" (error messages, so we can help you)

So here we are, i just typed the command, here is what i got then :

emerge: Maybe you meant any of these : media_sound/qtmpc, sci-libs/mc, app-misc/mc, media-gfx/qosmic

Code: Select all

emerge: Maybe you meant any of these : media_sound/qtmpc, sci-libs/mc, app-misc/mc, media-gfx/qosmic

I'm working on VMware 10.0.1 build-1379776

I have 4 partitions on my Gentoo:
- sda1 (20MB / Bootable)
- sda2 (1024mb)
- sda3 (Swap, 512 mb)
- sda4 (rest of free space)

First, i saw that i cannot modify files as i was on read-only mode, so i used this :
mount –o remount,rw /

That's th last command i used.

I made a documentation with all the commands i wrote, just in case ..

You are right. It is not in portage. I got it from the roslin overlay.
If you have to remount your root partition rw after rebooting you have a problem you might want to FIX first instead of remounting it.

I changed my partitions options on my fstab ("defaults" for every partition, execpting swap).
I rebooted the system, & then it works

Then, how can i get qmc2 from the roslin overlays ?

I'm currently connected in SSH with putty on my Virtual Machine, i have created a directory called "QMC2" in /home. Then i created a file with the following script: http://gpo.zugaina.org/AJAX/Ebuild/2610768/View

I saved it, & used :

Code: Select all

ebuild qmc2-0.42.ebuild compile

& I got this :

Code: Select all

Appending / to PORTDIR_OVERLAY...
!!! Repository 'x-' is missing masters attribute in '/metadata/layout.conf'
!!! Set 'masters = gentoo' in this file for future compatibility
ebuild: /home/qmc2-Directory/qmc2-0.42.ebuild: does not seem to have a valid PORTDIR structure

So i think it's not the way to get it installed...i'm a noob as i said ..
Maybe something went wrong when i installed my gentoo, & my layout.conf hasn't been created...

No worry, even if it didn't work out yet, you tried more than most people and are awfully close.

http://wiki.gentoo.org/wiki/Overlay/Local_overlay

Get your /usr/local/portage up and working, move the ebuild you got to the right name, digest it, build it

So finally the end is approaching i guess...
I followed the instructions & i got this :

Can't seem to see all the informations on my shell about dependencies that are needed, any commands like "less"/"more" to make it more easier to read it from shell ?
Anyway, QMC2 needs more files to run...
Then i was pretty sure that SDL was in cause, so i tried:

Code: Select all

root # emerge libsdl

& i remembered that, mainly, sdlmame was needed:

Code: Select all

root # emerge sdlmame

That send me this :

Am i in the right way ? Any tips ? (I'm praying god to make it works soon

)

If you look at the first screen, you see a comment about "--autounmask-write"
Using this options will add entries to your package files in /etc/portage
Once you have run "emerge qmc2 --autounmask-write" it will say it has made these entries.
Now run "etc-update" to add these entries into the files "/etc/portage/package.?"
The system has been told to allow emerging the program AND it's dependencies (like libsdl).
So if you run "emerge qmc2" after this it actually will.

I finally can't seem to make it works...so i thank you a lot for your patience & all your help, but i'm gonna give up; it's a class project, way too difficult, we discovered Linux 3 months ago without solid knowledge ...
There are so much problems & i have so much more other projects...but i thanks anyway !
