[Boost-users] Compilation problems on VC7 of code uses boost 1.31.0

10 Nov 2005

      Hi

I need your example in compilation errors on code uses boost under
Windows VC7 and HP-UX 11.11 aCC 3.55 in 64 bit mode.

We have the boost 1.31.0 successfully installed and used in our
products, in SunOS using Forte 6.5.3 CC, HP 11.11 using aCC 3.33,
Windows (W2k, XP) using VC6.

While porting our code to 64 bit, we have upgraded the development env`
to Forte 8.5.5 CC on Sun, aCC 3.55 on HP and VC7 on Windows.

Compilation of boost itself had no problem. However, compilation of our
products that using it has been failed on HP and Windows.

1. Problems on Windows:

We have the following piece of code that uses boost (copy/paste):

#include "boost/regex.h"
#include "boost/regex.hpp"

using namespace boost;
using namespace std;

typedef boost::reg_expression<char> re_type;
typedef re_type::allocator_type allocator_type;

long example_func(long pos, const std::string& regE, long& reslen, long
max)
{
  long res;
  boost::match_results  m;

  allocator_type (a);
  re_type e (a);

  e.set_expression (regE, regbase::normal);

  if (regex_search (begin (), end (), m, e, match_not_dot_newline |
match_not_dot_null))                        <-- line 4790
  {
    res = pos + m.position();
    reslen = m.length();
    return res;
  }
.
.
.

Compiling the above produce the following error:

<-- line 208
      // If last match was null and match_not_null was not set then

      // our start position, otherwise we go into an infinite loop:

Searching Google for this problem did not help very much, so I was
wondering if you have encounter it and put more light on it and the
solution?

2. Problems on HP:

2.1.

Error 24:
"/VOBS/netrac2_3rd_party/boost/delivery/include/boost/regex/v4/regbase.h
pp", line 53 # '<identifier>' expected instead of 'collate'.
          perlex = collate << 1,                 // perl extensions
                   ^^^^^^^                                         
Error 164:

pp", line 53 # Integral type expected for operator '<<'; types found

          perlex = collate << 1,                 // perl extensions
                           ^^^^                                    
We do not understand why the error occurs, can you help with that?  from
some reason, HP's aCC doesn't like the "collate".
Again, same as with problem #1, google it did not produce any useful
information.

We have workaround this problem as follow:

changed:

     collate = icase << 1,                    // use locale specific
collation
     perlex = collate << 1,                 // perl extensions

to:

     collate = icase << 1,                    // use locale specific
collation
     _collate = icase << 1,
     perlex = _collate << 1,                 // perl extensions

 What do you think about this solution?

2.2. Fixing above problem have exposed a problem similar to the Windows
problem.

Btw, both problems #1 and #2.2 were solved when set #define
BOOST_NO_STD_ALLOCATOR
