Core v7.0beta2
« on: January 19, 2016, 10:43:19 PM »
Team Tiny Core is pleased to announce that Tiny Core 7.0 Beta2 is available for public testing:

http://repo.tinycorelinux.net/7.x/x86/release_candidates/
http://repo.tinycorelinux.net/7.x/x86_64/release_candidates/

This is an beta level cut. If you decide to help test, then please test carefully. We don't want anyone to lose data.

Most extensions have been copied over from the 6.x repo - note that the alsa extensions have been refactored and updated and the Xorg-7.7 extensions have been updated.

We appreciate testing and feedback.

If you use distribution files note that you need a new vmlinuz and core.gz (or rootfs.gz + modules.gz)

Changelog for 7.0 beta2:
* busybox patched to fix "crontab -e" error
* kernel updated to 4.2.9 with the latest stable patch, with these config changes:
  - minstrel enabled for some wireless cards
  - vmmouse disabled for VMWare + Xvesa
  - the cpu limit on the 64-bit kernel raised to 64

Changelog for 7.0 beta1:
* busybox updated to 1.24.1
* kernel updated to 4.2.7
* glibc updated to 2.22
* gcc updated to 5.2.0
* e2fsprogs base libs/apps updated to 1.42.13
* util-linux base libs/apps updated to 2.27

Note that the drm/i915 kernel driver error is still not fixed.

'seems to work for me:
Code: [Select]
$ gcc -flto -fuse-linker-plugin -mtune=generic -Os -pipe hello.c
hello.c:1:1: warning: return type defaults to 'int' [-Wimplicit-int]

..and I just compiled busybox with it.

Did you load compiletc or just gcc?

Always nasty when gcc uses over-486 instructions when told to use 486 ones. I wonder which it was, just out of curiosity.

Can you try that in gdb? gdb --args gcc hello.c
run

The cursor works with Xvesa and VMware now so thanks. Autograb doesn't work but it didn't in TC 6 either and if it's important then open-vm-tools will need to be loaded. I can submit it once the following issue is resolved.

I have determined that the problem with /dev/fuse is that the permissions change when glib2.tcz is loaded. To reproduce, start with TC installed but no extensions loaded. Check /dev/fuse permissions, they should be 1666. Load dependencies libffi.tcz and gamin.tcz and check /dev/fuse. Should be no change. Load glib2.tce and check permissions. They are now 1600. I ran strace, it looks like some devices are being worked on but I can't tell for sure what's happening. I found some suspicious activity where "sudo /sbin/udevadm trigger" is doing this:

open("/sys/devices/virtual/misc/fuse/uevent", O_WRONLY|O_LARGEFILE) = 3
write(3, "change", 6)                   = 6
close(3)                                = 0

Maybe something is changing it back later when all the other extensions get loaded for open-vm-tools, but there over 90 more to load. Testing that will take a while.

Two other comments about the installed beta:

1. Both fltk-1.1.10 and fltk-1.3 extentions are loaded. Are they both necessary?
2. If another window manager like openbox is booted, then both it and flwm_topside extensions are loaded. Shouldn't flwm_topside not be in onboot.lst? Or is this a feature?

I'm guessing that you're using CorePlus?

As I recall, all of the extensions are loaded onboot - booting another window manager is a managed by changing the "desktop=" boot code in the syslinux menu.

If you're going to use tinycore for any length of time, I'd recommend a usb stick or hd install where you can customise things to load exactly what you need and nothing more.

I'd guess (without checking) that one of the window managers uses fltk-1.1.10, but you can easily check.

My "two other comments" were about a HD installation. There isn't a dependency for fltk-1.1.10 in any of the .dep files in optional, but it is in tc-install.sh so I'm suggesting that script needs to be updated. As you say, if someone wants to use a different window manager shouldn't that be the only one loaded?

@vt1431

Oh ok, lots of cmov. The build steps are all correct, so it might be a bug in upstream gcc. We may not be able to do anything, is it possible for you to build on a newer machine and just copy to the 586?
The only barriers that can stop you are the ones you create yourself.
