I have a c++ program I'm trying to get to compile which is
showing an error in the include file chain. First, versions:
gcc --version
gcc (SUSE Linux) 4.9.0
uname -a
Linux Ishtar 4.10.1-Isht-Van #1 SMP PREEMPT Tue Feb 28 18:57:48 PST 2017
x86_64 GNU/Linux
rpm -qf /usr/include/features.h
glibc-devel-2.19-16.9.1.x86_64
Invocation and output:
/usr/bin/g++ -Og -g3 -ggdb -m64 -march=native -fpic -pipe -std=c++11

__BEGIN_DECLS

-----
First part of the problem is in finding the location of the problem
in so much as the traceback given doesn't point to assert.h.
In features.h, at line 378, (starting at 375) I see:
/* This is here only because every header file already includes this
one. */
#ifndef __ASSEMBLER__
# ifndef _SYS_CDEFS_H
# include <sys/cdefs.h>
# endif
----
I.e -- no inclusion of assert.h, but instead, 378 is an inclusion of
<sys/cdefs>. Shouldn't the include chain have shown that file?
Second part of the problem is "why the error". I saw one or two
other people with this error in google who's problem was
some source error in their code before the include, but I tend
to reject that in my case, since there isn't much before the
includes that could cause such an error.
In cpumeter.cc, there is only a comment block before the inclusion of
cpumeter.h @ line 25 and in cpumeter.h, there are only comments
and an include-guard (ifndef/define). I see no code before those
include statements. I tried to follow the include chain, but am
hindered by it seeming to be inaccurate or incomplete.
So am sorta stuck --
Why am I getting this error, and how did I get to 'assert.h' (where
there is a __BEGIN_CDECLS?
Thanks much, in advance!
