On the "road" to build SFS with:
- glibc: 2.32
- gcc: 1.02.0
- binutils: 2.35

Building SFS with the new chain tool is not so bad:
- building the tools is ok
- the first package which is broken is tcp_wrapper (glibc-2.32: sys_nerr and sys_errlist are deprecated)
-----------------------
percent_m.c: In function 'percent_m':
percent_m.c:35:18: error: 'sys_nerr' undeclared (first use in this function)
35 | if (errno < sys_nerr && errno > 0) {
| ^~~~~~~~
percent_m.c:35:18: note: each undeclared identifier is reported only once for each function it appears in
percent_m.c:36:14: error: 'sys_errlist' undeclared (first use in this function)
36 | strcpy(bp, sys_errlist[errno]);
| ^~~~~~~~~~~
make[1]: *** [Makefile:681: percent_m.o] Error 1
make[1]: Leaving directory '/tmp/tcp_wrappers-7.6/tcp_wrappers_7.6'
make: *** [Makefile:152: linux] Error 2
---------------------

I made a comparison between the building of SFS with:
- 1/ binutils-2.35, glibc-2.32 and gcc-10.2
- 2/ binutils-2.35, glibc-2.31 and gcc-10.2

Concerning the 1/ try (glibc-2.32):
-----------------------
- building the tools is ok
- the first package which is broken is tcp_wrappers (glibc-2.32: sys_nerr and sys_errlist are deprecated)
-----------------------
percent_m.c: In function 'percent_m':

make[1]: Leaving directory '/tmp/tcp_wrappers-7.6/tcp_wrappers_7.6'
make: *** [Makefile:152: linux] Error 2
---------------------
I managed (nearly to make it built), by adding (see the following line added to the SlackBuild, to modify the Makefile):
---------------------
....
sh extract-and-patch.sh
cd tcp_wrappers_$VERSION || exit 1
# add -DHAVE_STRERROR to linux Makefile to solve glibc-2.32 deprecated sys_errlist and sys_nerr (from fedora 33 mas rebuild spec)
sed -i -e 's/-DHAVE_WEAKSYMS/-DHAVE_WEAKSYMS -DHAVE_STRERROR/' Makefile
make REAL_DAEMON_DIR=/usr/sbin linux
strip tcpd safe_finger tcpdchk tcpdmatch try-from
....
--------------------
but another error occured: libnsl from glibc-2.32 is not seen by tcp_wrappers (don't know why?):

Nobodino,

A couple little things that seem worth mentioning:

1: In sfs-bootstrap.sh, about line 423, shouldn't the order of export_variables_perso.sh and export_variables.sh
be reversed? This would allow pathnames from export_variables.sh to be over written allowing only one file
to be changed.

2: In the functions upgrade_{rsync,dvd,src} the statement "export $upgrade_sources" appears near the end if each. What is
intended here? Removing them doesn't seem do bother the program. All they seem to do is create and export
empty variables named "yes" or "no" that we selected above.

Hi Worsel, I took into account your suggestions.

due to new bison-3.7.x qt5-webkit doesn't build anymore.

Due to new bison-3.7.x qt-4.8.7 doesn't build anymore: the qtwebkit part.

By downgrading to bison-3.6.4 it builds normaly.

- ghostcript: failure because of freetype-2.14.3/2.14.4 but ok with freetype-2.10.2 (need patch from BLFS see link: https://github.com/nobodino/slackwar...ap/ghostscript)

- qt5-webkit: failure need patch (https://github.com/nobodino/slackwar...t/l/qt5-webkit)

note: libclc is now part of llvm-project, why is there a separate package?

a little more investigations:
- amarok: failure because of mariadb >= 10.5.0, but ok with mariadb-10.4.13
- pykde4: failure because of sip-4.19.23, but ok with sip-4.19.22
- artikulate: once qt-gstreamer is installed, artikulate builds ok.

only kppp and qt-gstreamer have no solution.

- qt-gstreamer: failure because of gstreamer-1.18.x and gst-plugins-base-1.18.x, but ok with gstreamer-1.16.3 and gst-plugins-base-1.16.2

only kppp has no solution.

-kppp: failure because of gcc-9.3.0, but ok with gcc-9.2.0

that's all folks.

- libclc : failure, need patch from debian (see link: https://github.com/nobodino/slackwar...rrent/l/libclc)
