Yes, I found that I used official (from ubuntu repositories) version
of gccxml. When I switched to binaries from gccxml_bin/v09/linux2/bin
everything went ok (whith one exception:
pygccxml/gccxml_bin/v09/linux2/share/gccxml-0.9/GCC/4.3 directory from
SVN version is empty and this causes an error. I copied
gccxml_biuldins.h from
pygccxml/gccxml_bin/v09/win32/share/gccxml-0.9/GCC/4.3).
Ok, but now I want to run all test included.
First of all I can't do it because of an error:
Traceback (most recent call last):
File "/home/mnowotka/pygccxml/pyplusplus_dev/unittests/test_all.py",
line 113, in <module>
import indexing_suites_v2_bug_tester
File
"/home/mnowotka/pygccxml/pyplusplus_dev/unittests/indexing_suites_v2_bug_tester.py",
line 14, in <module>
import dl
ImportError: No module named dl
As far I know, this was a bug in python on x86_64 enviroments. Is
there any way around this dependency?
Secondly, when I exclude indexing_suites_v2_bug test I can see that
not all the other tests were completed successfully:
! test (custom_smart_ptr_classes_tester.tester_t) - FAIL
! test (deepcopy_tester.tester_t) - FAIL
! test (virtual_inheritance_tester.tester_t) - ERROR
Does it mean smart pointers and virtual inheritance is not supported
under linux? Are there any workarounds?
And finally another use case. Consider following code:
#include <utility> //here is std::pair defined
class I
{
public:
I(int a, int b)
{
pair_.first = a;
pair_.second = b;
}
std::pair<int, int> pair_;
int compute(){return pair_.first + pair_.second;}
};
After parsing it Py++ produces warning:
WARNING: std::pair<int, int> [struct]
> execution error W1040: The declaration is unexposed, but there are other
> declarations, which refer to it. This could cause "no to_python converter
> found" run time error. Declarations: I::pair_ [variable]
I don't understand it because indexing suite v2 can handle vectors,
sets, deques etc. so why pair is here an exception? There is pair.hpp
file in indexing_suite directory so I guess this package can work with
std::pair. Even if I add following lines
(IMO completely useless in this case):
namespace pyplusplus{
namespace aliases{
typedef std::pair< std::string, int > PairOfStringInt;
void instantiate( PairOfStringInt psi){}
typedef std::pair< std::string, double > PairOfStringDouble;
void instantiate( PairOfStringDouble psd){}
}
}
or:
int a = sizeof(std::pair< std::string, int >);
int b = sizeof(std::pair< std::string, double >);
I still get this warning.
I also read this discussion:
http://sourceforge.net/tracker/index.php?func=detail&aid=1991168&group_id=118209&atid=684318
but adding these lines:
mb.class_('PairOfStringInt').include()
mb.class_('PairOfStringDouble').include()
or:
mb.class_('std::pair< std::string, int >').include()
mb.class_('std::pair< std::string, double >').include()
doesn't solve the problem and generate error:
pygccxml.declarations.matcher.declaration_not_found_t: Unable to find
declaration. matcher: [(decl type==class_t) and (name==std::pair<
std::string, double >)]
so how should I modify the code to get std::pair exposed?
