I haven't built a new system since April, so I thought it was time
to test current -svn. In particular, I wanted to see how bison-3.0
impacted other packages. But I can't even build it!
make[2]: Entering directory `/building/bison-3.0'
CC lib/math.o
CC lib/mbswidth.o
CC lib/pipe2.o
CC lib/pipe2-safer.o
In file included from lib/pipe2.c:20:0:
lib/unistd.h:603:1: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'extern'
_GL_CXXALIAS_SYS (close, int, (int fd));
^
followed by a stream of errors, the first several of which are also
complaints about 'extern'.
At this point my obvious divergences from the book are:
1. building in '/building' (/sources is an nfs mount)
2. setting CFLAGS and CXXFLAGS to "-O2"
3. glibc built with --enable-kernel=3.9.0
AFAICS, all the versions and patches up to this point match what is
in the current book. This is x86_64, *host* is LFS r10258
(2013-04-29) plus headers from 3.9 kernel, zlib-1.2.8 (I put those
into the book after this host built everything ok), and eudev insted
of Bruce's udev-from-systemd - none of which seem likely to affect
this problem.
The lines of the bisonlib/unistd.h header are:
#if 1
# if 0
/* Automatically included by modules that need a replacement for
* close. */
# if !(defined __cplusplus && defined GNULIB_NAMESPACE)
# undef close
# define close rpl_close
# endif
_GL_FUNCDECL_RPL (close, int, (int fd));
_GL_CXXALIAS_RPL (close, int, (int fd));
^^^ barfs here
# else
_GL_CXXALIAS_SYS (close, int, (int fd));
# endif
_GL_CXXALIASWARN (close);
#elif 0
# undef close
# define close close_used_without_requesting_gnulib_module_close
#elif defined GNULIB_POSIXCHECK
# undef close
/* Assume close is always declared. */
_GL_WARN_ON_USE (close, "close does not portably work on sockets - "
"use gnulib module close for portability");
#endif
I've always been frightened of bison, now I know why :-) Any
ideas, please ?
