Boost under QNX 6.2.1
by Dave Wolfe 21 Jul '04

21 Jul '04

I recently tried to d/l boost_1_31_0 and compile a short test program (appended below) on QNX 6.2.1. My first attempt to compile with: % make bindtest CPPFLAGS=-I/home/projects/boost_1_31_0 resulted in a yard+ of errors that I was able to quiet by adding '-ftemplate-depth-32' to CPPFLAGS. But I still got the error: g++ -I. -ftemplate-depth-32 bindtest.cpp -o bindtest /tmp/ccIdnnhy.o: In function `boost::bad_function_call::bad_function_call(void)': /tmp/ccIdnnhy.o(.boost::bad_function_call::gnu.linkonce.t.(void)+0x29): undefined reference to `runtime_error::runtime_error(basic_string<char, string_char_traits<char>, __default_alloc_template<false, 0> > const &)' collect2: ld returned 1 exit status make: *** [bindtest] Error 1 After quite a lot of mucking about, I discovered that I had to define CXX to 'QCC' and comment out the following line in boost/config/compiler/gcc.hpp: #ifndef __EXCEPTIONS //# define BOOST_NO_EXCEPTIONS #endif in order to compile successfully. So the appended test program works, at least. However, the complete boost tarball seems to have some problems. When I run bjam, the compiler keeps carping: g++: unrecognized option '-pthread' And there seem to be quite a few files with a basename longer than the QNX max of 48 charactes. I'm willing to help figure out how to get boost to compile better under QNX if someone can give me a little guidance as to how to proceed. Part of the problem may be that QNX 6.2.1 uses an STL implementation from Dinkum instead of the one that comes with gcc 2.95.3. If someone'll help direct my fingers where to go, I can probably sort some of this out... Cheers, - Dave P.S. If it's helpful to anyone, I can post a QNX 6.2.1 binary of bjam... -------- % uname -a QNX rtblnx1196 6.2.1 2003/01/18-02:12:22est x86pc x86 % gcc --version 2.95.3qnx-nto -------- // File: bindtest.cpp // Compile: make bindtest CXX=QCC CPPFLAGS="-I. -ftemplate-depth-32" #include <iostream> #include <string> #include <boost/bind.hpp> #include <boost/ref.hpp> #include <boost/function.hpp> using namespace std; typedef boost::function<void(void)> Callback; struct Dummy { void memberFunc( int num, const string& msg ) { cout << "memberFunc args: " << num << ", \"" << msg << "\"" << endl; } }; main( void ) { Dummy mydummy; Callback c = boost::bind( &Dummy::memberFunc, boost::ref(mydummy), 7, "is a lucky number..." ); c( ); // prints: "memberFunc args: 7, "is a lucky number..." return 0; }

counting_iterator_test.hpp fails on aC++
by DY, JERRY U (SBCSI) 21 Jul '04

21 Jul '04

I'm troubleshooting counting_iterator_test.hpp. In particular: FILE: counting_iterator_test.cpp class my_int2 { public: ... typedef std::bidirectional_iterator_tag iterator_category; }; FILE: counting_iterator.hpp template <class Incrementable, class CategoryOrTraversal, class Difference> struct counting_iterator_base { typedef typename detail::ia_dflt_help< CategoryOrTraversal , mpl::apply_if< is_numeric<Incrementable> , mpl::identity<random_access_traversal_tag> , iterator_traversal<Incrementable> > >::type traversal; ... } The class my_int2 is passed as parameter "Incrementable" to counting_iterator_base, but is failing the is_numeric test so my_int2 is just a bidirectional iterator (see mpl::apply_if above). If it passes the is_numeric test, then it's a random access traversal tag. The way it passes the is_numeric test is to specialize std::numeric_limits like so: template <> class std::numeric_limits<my_int2> { public: static bool const is_specialized = false; }; But I don't find that in the source. It appears that aC++ doing the right thing, but I know I'm wrong. Could somebody please help?? Thanks! -Jerry

Essentially uBLAS just makes use of the system <complex> header. How this result in an unresolved symbol I don't know. My wild guess the they are normally for it the compiler runtime, and something has gone haywire! > "C:\Programme\Intel\CPP\Compiler80\Ia32\bin\icl" /Zm800 -nologo -GX -c > -DBOOST_UBLAS_USE_INTERVAL /Z7 /Od /Ob0 /GX /GR /MDd /Op /Zc:forScope > /Zc:wchar_t /Qwn5 /Qwd985 -Qoption,c,--arg_dep_lookup /Qansi_alias > -D_NATIVE_WCHAR_T_DEFINED /Qvc7.1 I am really guessing here as I don't have manuals! The /Z7 and /Qv7.1 look interesting. I think the /Z7 is specifying old style debug symbols which is a bit odd. I guess they are usually smaller then the "edit and continue" symbols. /Qv7.1 I assume is enabling VC 7.1 compatibility bugs and all. I guess this adds a few extra bugs of Intels own. I not sure why the default build options for boost have this in. Anyone know? Do you think it would be appropriate to do the regression testing in the compilers native mode? Thanks, Michael

Wow, lotsa updates last night

The full log is in the usual place ( ftp://rudbek.com/pub/boost/status.log ) I attempted to "fix" the lower and upper ambiguous symbols by changing lower(value) to value.lower() and the same for upper(value), but that causes problems later in the compile when apparently some ublas things are being used. .....perhaps the solution will be to add the required methods lower()const and upper()const to the ublas system. at any rate, here are the "interesting" lines: File: status.log ...found 38391 targets... ...using 2 temp targets... ...updating 4251 targets... ...on 100th target... ...on 200th target... ...on 300th target... ...on 400th target...
