back to slackware-14.2:
-removed dlackware option
-builds kde:
-some packages don't build because of cmake (kgamma, kuser and kdeartwork)
-kdesdk-kioslaves (svn ?)
-calligra (don't know why)
-pykde4 (dnssd ?)
Everything else builds.
By rebuilding qt, qt-gstreamer builds now.
Near the end of building slackware-14.2 entirely.

Lol you are building the whole of KDE from scratch? Oh joy.

Well, Nobodino,

Looks like you are making more progress than I am. Main problem is lack of time and energy.

I downloaded the new scripts and will test them as soon as possible.

error in build4_s.list : add "l qt" before "l qt-gstreamer"

new improvement:
- bivalent: able to build slackware-14.2 and slackware-current

Nobodino,

Ran your build from 2016-12-14, first part anyway.

Went smoothly. Only a couple of minor nits so far (I won't be able to do any
extensive testing until after Christmas).

1: chroot1.sh is referred to in message_end1(). It does not exist.

2: After the build, there were two error messages:

Neither directory exists. I'll look into this next week.

Have a merry Christmas and a Happy New Year!

I have made some progress on building kde, just calligra resists.
I had to introduce old version of cmake, subversion and taglib from slackware-14.1 in 'others' to be able to build the missing packages.
To build pykde4, I copied the patch from current in kde source tree.
-sfsinit.sh is just modified for build4_s.list
-sfsbuild1.sh is modified to change the rules to build each kde package, the previous one was not working very well
-chroot1.sh is enclosed

It is near the end of building the entire slackware-14.2.
There are certainly some packages missing.

Nobodino,

Continuing the testing of your scripts from 2016-12-24, I find that
the subroutine "gcc_build64_14_2" does not exist in sfsbuild1.sh.
Instead you have twosubroutines named "gcc_build64_c". This is also
true in your scripts from 2016-12-16.

Nobodino,

After correcting the names in the last post, gcc (complete) compiled ok.
Working on the last list now.

This time, slackware-14.2 is nearly complete (just linux-faq, howtos, ipset (need same kernel in chroot) and kernel packages remains), everything else has been built.
I managed to built kde entirely till the end...
I enclosed a diff-list of the packages in slackware-14.2 and those I built.

Just out of curiosity, why do the ARCH differs for bsd-finger (32-bit vs 64-bit)?

I joined the diff-list because they're some curiosities like this one and others.

Is it possible to modify variables in your script to build with -march=native?

Does this build and install all of Slackware without rebooting?

-1st question: I don't know? maybe.
-2nd question: yes, "you can".

I added now the last packages: kernel-generic, kernel-huge and kernel-generic-smp.
I built doxygen must sooner by playing with flex-2.5.39 and flex-2.6.0.
I built 'ipset' after rebooting in the new environment.
Just remains the 'linux-faq' and 'linux-howtos' packages.
I think that's finished for me for slackware from scratch 14.2.

Little did you realize that it is just the beginning. In fact, now you have to get your scripts to compile everything with clang.
