           Summary: xxx.c:1:20: stdint.h: No such file or directory
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: preprocessor
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: danglin at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: hppa2.0w-hp-hpux11.00
  GCC host triplet: hppa2.0w-hp-hpux11.00
GCC target triplet: hppa2.0w-hp-hpux11.00

# cat xxx.c
#include <stdint.h>
# ./xgcc -B./ -E xxx.c
# 1 "<built-in>"
# 1 "<command line>"
# 1 "xxx.c"
xxx.c:1:20: stdint.h: No such file or directory
# echo $?
0

stdint.h doesn't exist on hppa2.0-hp-hpux11.00.  The message is correct
but the exit value for gcc is wrong.  Adding "-Werror" doesn't affect the
exit value.

This causes configure checks in libiberty and libstdc++-v3 to break.  For
example,

configure:5490: checking for stdint.h
configure:5507: /xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/ 
-B/opt/gnu/hppa2.0w-hp-hpux11.00/bin/ -B/opt/gnu/hppa2.0w-hp-hpux11.00/lib/ -isy
stem /opt/gnu/hppa2.0w-hp-hpux11.00/include -isystem /opt/gnu/hppa2.0w-hp-hpux11
.00/sys-include -c -O2 -g -O2 -O2 -g -O2 conftest.c >&5
configure:5551:20: stdint.h: No such file or directory
configure:5510: $? = 0
configure:5513: test -s conftest.o
configure:5516: $? = 0
configure:5527: result: yes

The result is numerous regression in the g++ testsuite because stdint.h
gets included by the v3 headers.

------- Additional Comments From danglin at gcc dot gnu dot org  2003-10-31 17:45 -------
Problem found:

We have the following includes in cppfiles.c:

#include "config.h"
#include "system.h"
#include "cpplib.h"
#include "cpphash.h"
#include "intl.h"
#include "mkdeps.h"
#include "hashtab.h"
#include <dirent.h>

cpphash.h results in these includes:

# 29 "../../gcc/gcc/cpphash.h"
# 1 "/usr/include/iconv.h" 1 3 4
# 22 "/usr/include/iconv.h" 3 4
# 1 "/usr/include/dl.h" 1 3 4

dl.h defines the following "DL_" macros when using the 32-bit SOM port:

#define DL_OPEN         48
#define DL_CLOSE        52
#define DL_SYM          56
#define DL_ERROR        60

The define for DL_ERROR conflicts with the earlier define in cpplib.h:

/* An error.  */
#define DL_ERROR                0x03

I guess we must be suppressing warnings/errors from system headers, or
there is a problem with detecting redefined macros as I don't see any
warnings compiling cppfiles.c.

I also see the same problem under hpux 11.11, although it doesn't affect
the 64-bit port.

------- Additional Comments From danglin at gcc dot gnu dot org  2003-10-31 18:26 -------
I believe that it was this patch that introduced the regression:

2003-07-04  Zack Weinberg  <zack@codesourcery.com>

        * cpphash.h: Include <iconv.h> if we have it, otherwise
        provide a dummy definition of iconv_t.
        (struct cpp_reader): Add narrow_cset_desc and wide_cset_desc fields.
        (_cpp_valid_ucn): Update prototype.
        (_cpp_destroy_iconv): New prototype.

I would say submit a patch which changes the name of all the DL_* macros in gcc to fix this 
problem.

It looks as if a prefix of "CPP_" would be consist with what has been done
in other places in the file.

I would prefer it if you could try to use the enumeration defined in diagnostic.h
instead.  I don't know if this is feasible.  If not, CPP_* prefixes are fine.

I have a patch using the latter approach under test.  I would like
to resolve this issue as there are a number of other problems affecting
pa and vax builds.  After the prefix change, you can explore using
the enumeration at your leasure.
