[Bug c++/42880] New: trunk does not compile boost MPL

[piotr dot wyderski at gmail dot com]

gcc version 4.5.0 20100126 (rev. 156253) is
not able to compile the following "program":

#include <boost/mpl/size.hpp>

version 20100115 didn't complain. I've checked
it on boost 1.37 and 1.39. For those who don't
have boost installed, there is a preprocessed
file from boost 1.39.

I'm seeing two problems here: on x86_64-linux I can see only the last error,
about specialization / redefinition, can well be a non-bug but can also be a
regression, I'm CC-ing Dodji about it; plus, apparently something is
specifically going wrong on cygwin at configure time, I see char_16t etc
issues. I'm CC-ing two cygwin maintainers about it.

Ok. If you could figure out more precisely *when* the first problem started on
cygwin, it would be very useful.

------- Comment #6 from davek at gcc dot gnu dot org  2010-01-27 12:06 -------
I tried building the preprocessed source with my stock 4.3.4 compiler.  The
first two error messages are about the undefined wide char types, then there's
a massive cascade of template errors following on from that.

Cygwin provides a uchar.h that defines char16_t and char32_t.  I checked that
none of the #-directives in the preprocessed source referred to uchar.h, so if
boost fails to include it and boost gets an error about these types being
undefined, I think that is likely to be a boost bug rather than a cygwin or gcc
problem.

I therefore don't propose to investigate this any further, unless new evidence
comes to light.

Also note: something is going on with char16_t / char32_t which I do not
understand at all, at the moment: in that tr1_impl code I did not setup the
specializations for char16_t / char32_t conditionally to some configure check
or header included or actual target, because I was assuming that in C++, in
C++0x mode, those are **always** available. Is that not true? And we didn't
realize for all this time?!?

Note, actually the error means the submitter is passing -std=c++0x on the
command line.

My code compiled flawlessly on 4.5.0-20100115,
otherwise I would have reported the issue earlier...

20100126 has been built in a clean directory, so
no interferences with previous builds are possible.

Paolo: yes, -std=gnu++0x -- it's the reason I use trunk.

  I don't understand.  There's no equivalent in g++ of the builtin stdint types
that Joseph added for C, so if you don't include the header that defines them,
no definitions should be available, yes?

That didn't make any difference to the undefined types errors, but it did fix a
lot of the knock-on errors I was seeing.

Can you attach the preprocessed source you get from that build of the compiler,
so we can see why it either a) finds definitions of the ucharXX_t types, or b)
doesn't attempt to declare templates referring to them?

Then say that explicitly, *always*. Actually, the complete command line is part
of the requirements for PRs.

But, anyway, that error with char16_t and char32_t doesn't make *any* sense to
me. We have plenty of testcases in the C++ testsuite for char16_t and char32_t
on all the targets, working fine without including any header. Can you compile
something as simple as this:

char16_t a;

with -std=c++0x (or -std=gnu++0x)? If you can't, then this is something which
is much more general than boost MPL; if you can, something inside boost MPL is
playing weird tricks with those names.

Dave, please grep the C++ testsuite for char16_t and char32_t: you will find
tons of testcases using those types + -std=c++0x on the command line, no
special target-dependent treatments, no includes whatsoever.

Unfortunately not, because I assumed that the new compiler
will work, so make install overwritten the binaries of 0115.
Anyway, I think I have an earlier build somewhere (20100107)
which also works, so I will provide you a preprocessed source
from that version.

So, as a matter of fact, char16_t and char32_t normally work on cygwin too.

Ah, hang on.  I may have got some of my revision numbers mixed up there.  (I

However, note there's still no problem with the wide char types.

Sorry, I misunderstood you. I use -std=gnu++0x in my
actual program, which today became uncompilable. For
the PR it was:

    g++ -std=gnu++0x br.cpp -I/usr/include/boost_1_39_0/

Without extensions enabled, merely:

    g++ br.cpp -I/usr/include/boost_1_39_0/

the compiler also emits an error list, however much
shorter (it's probably what you see on Linux): specialization
after instantiation.

Those versions are:

gcc version 4.5.0 20100121 (experimental) (GCC)
gcc version 4.5.0 20100125 (experimental) (GCC)

So I can confirm the specialisation error that you've also seen on x86_64-linux
has also appeared on cygwin, but I can't yet confirm any bug about the char
types.

Excellent Dave. Thus, we are looking for confirmation of the char16_t /
char32_t issue, we don't see it on our cygwin and linux machines.

And we should nail down more precisely in time the specialization /
redefinition issue, can be a regression or g++ becoming more strict.

OK, so I'll try updating my most recent build from 156219 to 156253 and see if
that makes a difference re. the char types.

On 20100126: a lot of errors, the amount depends
on the presence of -std=gnu++0x

I have no intermediate builds between 15 and 26,
so can't reduce the range any more.

I double-checked the compilers used to generate
them -- the attachments are correct. So the issue
must be inside the compiler itself, not in its
stdc++ includes.

Indeed, and that matches what Paolo said in comment 13.  I've now built
r.156253 and here is the output from compiling your testcase; it still shows no
sign of the charXX_t problem:

So, the bug is that it #includes tr1_impl even if the compiler is not in c++0x
mode perhaps?  It appears to be coming from the regular type_traits header:

# 1 "/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/stddef.h" 1 3 4
# 45 "/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/cstddef" 2 3
# 43 "/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/type_traits" 2 3
# 51 "/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/type_traits" 3
# 1 "/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/tr1_impl/type_traits"
1 3
# 30
"/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/tr1_impl/type_traits"   3
namespace std
{

# 43
"/opt/PREFIX/LIB/gcc/i686-pc-cygwin/4.5.0/include/c++/tr1_impl/type_traits"


Hmmm.  That comes from here:

    44  #if defined(_GLIBCXX_INCLUDE_AS_CXX0X)
    45  #  include <tr1_impl/type_traits>
    46  #else
    47  #  define _GLIBCXX_INCLUDE_AS_CXX0X
    48  #  define _GLIBCXX_BEGIN_NAMESPACE_TR1
    49  #  define _GLIBCXX_END_NAMESPACE_TR1
    50  #  define _GLIBCXX_TR1
    51  #  include <tr1_impl/type_traits>
    52  #  undef _GLIBCXX_TR1
    53  #  undef _GLIBCXX_END_NAMESPACE_TR1
    54  #  undef _GLIBCXX_BEGIN_NAMESPACE_TR1
    55  #  undef _GLIBCXX_INCLUDE_AS_CXX0X
    56  #endif

and then tr1_impl/type_traits has:

   111  #ifdef _GLIBCXX_INCLUDE_AS_CXX0X
   112    _DEFINE_SPEC(0, __is_integral_helper, char16_t, true)
   113    _DEFINE_SPEC(0, __is_integral_helper, char32_t, true)
   114  #endif

That kind of looks peculiar to me, but I don't know how the libstdc headers are
put together.  But why would we #define _GLIBCXX_INCLUDE_AS_CXX0X when we're
not in C++0x mode?

------- Comment #28 from davek at gcc dot gnu dot org  2010-01-27 15:31 -------
I've just gone back through the older compiler versions I have lying around. 
None of them can successfully compile the testcase without -std=c++0x at all,
they all complain about the missing types in the same way.  So I think the
stuff to do with char types is just a red-herring that happened while Piotr was
trying out the standalone testcase, by omitting the -std flag.

------- Comment #29 from paolo dot carlini at oracle dot com  2010-01-27 15:31 -------
To be clear: when the tr1_impl/type_traits implementation code is included as
tr1 code, is included from <tr1/type_traits> that is, _GLIBCXX_INCLUDE_AS_CXX0X
is undefined and no error should happen. Likewise, when the
tr1_impl/type_traits code is included as C++0x code, from <type_traits> that
is, the macro is defined, but no problem should occur in that case too because
char16_t and char32_t are certainly available in C++0x mode.

In practice, on linux I can compile the provided one-line snippet, both with
-std=c++0x and without, and get *only* the errors unrelated to char16_t /
char32_t. This doesn't suprise me, because in the libstdc++ testsuite we are
*very* careful about these things: we have tons of testcases including
<type_traits> and <tr1/type_traits> in normal mode, c++0x mode, etc.

If Dave, you have evidence that older versions of GCC always needed -std=c++0x
in order to compile this boost code, this is a cygwin-specific issue: I just
tried with a 4.4.x gcc and I can compile it without -std=c++0x.

This is 4.3.4, the stock cygwin distro version right now:

DKAdmin@ubik /tmp/boost
$ cat test.cpp
char16_t a;

DKAdmin@ubik /tmp/boost
$ g++ -c test.cpp
test.cpp:1: error: 'char16_t' does not name a type

DKAdmin@ubik /tmp/boost
$ g++ -c test.cpp -std=c++0x
test.cpp:1: error: 'char16_t' does not name a type

DKAdmin@ubik /tmp/boost

I take it that much is unsurprising?

This is the oldest version of trunk I have lying around, from r155967:

DKAdmin@ubik /tmp/boost
$ /gnu/gcc/install-clean/opt/gcc-tools/bin/g++-4 -c test.cpp
test.cpp:1:1: error: 'char16_t' does not name a type

DKAdmin@ubik /tmp/boost
$ /gnu/gcc/install-clean/opt/gcc-tools/bin/g++-4 -c test.cpp  -std=c++0x

DKAdmin@ubik /tmp/boost

That is also how everything up to r156253 behaves.  Is there something wrong
with that?

Dave, the issue with char16_t / cha32_t is cygwin specific, and, to be really
honest, personally I'm not interested in cygwin much. My suggestion is just
making sure the C++ front-end is fine for cygwin vs char16_t / char32_t, ans
simply running the C++ testsuite should be more than enough. If eventually you
come to the conclusion that some special workrounds in the C++ runtime is
needed to support cygwin, let's discuss that separately.

I'll run the testsuite on today's build and see if it differs from my most
recent run, which was pretty clean.  More later when that finishes.

(I thought the problem was that the preprocessed testcase was prepared using
-std=c++0x and therefore embeds all the #ifdef decisions made using that
standard, and so the preprocessed testcase must be compiled using the same
-std= which was used to prepare it.)

Right Dave, that's why we ask submitters to also provide the actual command
line used. Anyway, sorry about a bit of harshness on my side, I'm afraid we are
digressing too much in this thread: for sure, if I just take the one-liner
provided by submitter the errors I get are the same, with and without
-std=c++0x, and with 4.4.x I can compile it with no errors, irrerspective of
the command-line switches. This is what I consider sane behavior modulo the
*possible*, yet to be confirmed, C++ front-end issue with specialization /
redefinition.

Right, you mean the one-liner #include <boost/mpl/size.hpp>, so of course if
you compile it either different way the live #ifdefs respond correctly, and in
the non -std=c++0x compile, you don't get the template definitions for the wide
char types.  I don't have boost installed, so I've been relying on the
preprocessed source, which of course is good only for C++-0x.  (I wasn't clear
whether you were implying that the charXX_t definitions should exist in
non-c++0x mode, but I think now that they are c++0x only and that because you
were using live boost headers your compile succeeds.)

> This is what I consider sane behavior modulo the

Testsuite run is showing nothing unexpected either, and I couldn't really
imagine what Cygwin could possibly have done to break the presence of a couple
of builtin types in the C++ FE anyway.  So yes, sorry for taking some time to
get to this point, but I now also think that's the only possible issue here,
and there is no cygwin specific problem nor char types problem.

has absolutely nothing to do with c++0x.
