Some packages may need an adaption with GCC 14

Serious issues marked as bold.

cmake (3.28.1)

​https://gitlab.kitware.com/cmake/cmake/-/commit/806c40a38fc6e1996738173ecfa23a26f7502dbf

Two tests fail.

Fixed 3.28.2.

xmlto (0.0.28)

FTBFS:

Configure script wrongly probe things and then FTBFS:

termcap.c:45:14: error: conflicting types for 'boolcodes'; have 'char *[]'
   45 | static char *boolcodes[] = {
      |              ^~~~~~~~~

                 from termcap.mdh:15,
                 from termcap.c:38:

make[3]: *** [Makefile:230: termcap.o] Error 1

Note that simply fixing up termcap.c will cover up the real issue and produce an zsh executable hanging at runtime. The upstream changes can be done via sed:

sed -i -e 's/^main/int &/' -e 's/exit(/return(/' aczsh.m4 configure.ac
sed -i 's/test = /&(char**)/'                    configure.ac
autoreconf

aalib (1.4rc5)

FTBFS. Many issues need fix.

• Run autoreconf to regenerate the configure script with modern autoconf.
• Fix aatest.c, aafire.c, aasavefont.c, aainfo.c, aaregist.c, aalib.c, and aalinuxkbd.c for missing stdlib.h
• Fix aatest.c, aaregist.c, aakbdreg.c, and aamoureg.c for missing string.h
• Fix aaxkbd.c for missing X11/Xutil.h
• Fix aalinuxkbd.c rawmode_init() for bad return

polkit (124)

FTBFS unless disabling test.

• Missing prototype void print_indent(FILE *, unsigned int); in test/mocklibc/src/netgroup.h
  • Note that stdlib.h is needed for FILE.

accountservice (23.13.9)

FTBFS.

• Same issue as polkit. Note that in accountservice mocklibc is a shipped tarball and it only gets untarred after meson setup, so the fix up needs to be placed after meson setup.

libcddb (1.3.2)

FTBFS.

• In lib/cddb_net.c size_t l; needs to be changed to socklen_t l;

QT6 (6.7.1, maybe earlier versions, too)

FTBFS in a i686 VM.

a patch using

sed -e "/^#elif defined(Q_CC_GNU_ONLY)/s/.*/& \&\& 0/" \
    -i qtbase/src/corelib/global/qtypes.h

seems to fix that. No issues on same machine with gcc-13.
