[blfs-dev] math.h : No such file or directory (from gcc)

[Alain Toussaint]

Hello,

Someone have any clue how to solve this:


In file included from ../../include/c99_math.h:194:0,
from ../../src/gallium/auxiliary/util/u_math.h:44,
from ../../src/mesa/main/macros.h:35,
from glsl_types.cpp:25:
/usr/include/c++/7.3.0/cmath:45:15: erreur fatale: math.h : Aucun fichier
ou dossier de ce type
#include_next <math.h>
^~~~~~~~
Aucun fichier ou dossier de ce type == No such file or directory.

LFS-SVN hand-built (i.e. no ALFS used) but BLFS is currently building with
ALFS.

gcc stage two from chapter 5 and gcc chapter 6 built with
--enable-bootstrap and both were checked out with the testsuite.

absolutely no CFLAGS or CXXFLAGS used.

Installation support for LFS was a usb key with LFS+some BLFS built from
svn checkout from two weeks ago, the linux kernel v4.14.14 boot to a 2.5GB
ramdrive (I have 32GB of ram in that machine) and is pretty much self
contained.

At the moment, I have over 250 packages from BLFS built but this is the
first time I encounter that error.

What was compiling was mesa-17.3.3 with these settings:

GLL_DRV="nouveau"
./configure CFLAGS='-O2' CXXFLAGS='-O2' LDFLAGS=-lLLVM \
--prefix=$XORG_PREFIX \
--sysconfdir=/etc \
--enable-texture-float \
--enable-osmesa \
--enable-xa \
--enable-glx-tls \
--enable-dri3 \
--disable-llvm \
--with-gallium-drivers="" \
--with-platforms="drm,x11,wayland" \
--with-dri-drivers=$GLL_DRV


I suspect something's seriously afoul if gcc can't find a standard header
and I may need to restart the whole build from scratch. Also suspecting
hardware issues but there was only one thread compiling (make -j1 used at
all times).

Trying a build without LDFLAGS did not fix the issue.

Just to do some more testing, I updated my svn tree for jhalfs-dev, LFS
and BLFS; started a new build of LFS with ALFS and upon building chapter 5
gcc stage 1, I get this error:

^~~~~~~~~~

I do think I have to restart from scratch as gcc seem to be broken.

Ouch! I've just replied to your initial post, I suspect something
is wrong in your copy of the book from which you are extracting the
commands.

^^^^^^

We have dropped --with-dri-drivers, and we use
--with-gallium-drivers=$GLL_DRV (double checked against today's
book).

I built nouveau and a host of other gallium drivers like that
yesterday.

Not sure how you managed to get what looks like an old set of
commands.

I modified the ALFS generated script by hand, these settings are my own
but the original setting from an svn checkout of BLFS from yesterday
didn't compile because of missing amdgpu support in llvm (which was in
turn modified because llvm with the amdgpu support didn't compile).

I have many failure to report but then, my computer doesn't have all the
software built and at the moment, I make do with alpine and lynx instead
of a gnome desktop.

When include_next does not work it may be that some headers have been
"include-fixed" and should not have been. Try running (as root):
-------
/usr/libexec/gcc/x86_64-pc-linux-gnu/7.1.0/install-tools/mkheaders
-------
before anything else.

See the Caution on the BLFS GCC page.

Forgot to remove the SPAM header in the preceding, and also this should
be updated to:
/usr/libexec/gcc/x86_64-pc-linux-gnu/7.3.0/install-tools/mkheaders
