That already makes it more clear.

Yeah, I know. Happens since gcc 7.3

Is not really helpful. The root cause is (see config.log):

configure:28374: checking glm/glm.hpp usability
configure:28374: /usr/bin/ccache x86_64-linux-gnu-g++ -c -g -O2 -fdebug-prefix-map=/data/rene/git/LibreOffice/master=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 conftest.cpp >&5

Maybe I need to include an additonal header (as the real code does)? The configure check above just does

    AC_LANG_PUSH([C++])
    AC_CHECK_HEADER([glm/glm.hpp], [],
       [AC_MSG_ERROR([glm/glm.hpp not found. install glm])], [])
    AC_LANG_POP([C++])

Judging from the above error message it _does_ see the other headers, though.

Anyways, this was worked around in the recent upload of LO 6.0.0 rc3:

libreoffice (1:6.0.0~rc3-1) experimental; urgency=medium

  * New upstream release candidate

  * debian/patches/apparmor-fixes.diff: add patch from master with syntax
    fixes. Also include X abstractions and allow .mozilla/firefox/** reading
  * debian/patches/apparmor-updates.diff: more gpg stuff: gpg(sm), .gnupg/*
  (both together closes: #887593)
  * debian/rules, debian/source/include-binaries: temporarily use internal glm;
    configure check fails since the gcc 7.3 upload

Guus, any idea?
