Not too shy to talk

@all

I have compiled Beworld's port fheroes2 V1.0.0 (Heroes of Might and Magic II engine). Thanks to Beworld, I made BigEndian fixes.

However after starting the game , game shutdowns itself with these error in CLI windows:

"Expection 'basic_sting::M_create' occured during application time

I looked at sources and basic_string is only used here.

What may be wrong ?

maps_fileinfo.cpp:


namespace

{

    const size_t mapNameLength = 16;

    const size_t mapDescriptionLength = 200;



    template <typename CharType>

    bool CaseInsensitiveCompare( const std::basic_string<CharType> & lhs, const std::basic_string<CharType> & rhs )

    {

        typename std::basic_string<CharType>::const_iterator li = lhs.begin();

        typename std::basic_string<CharType>::const_iterator ri = rhs.begin();



        while ( li != lhs.end() && ri != rhs.end() ) {

            const CharType lc = std::tolower( *li, std::locale() );

            const CharType rc = std::tolower( *ri, std::locale() );



            ++li;

            ++ri;



            if ( lc < rc ) {

                return true;

            }

            if ( lc > rc ) {

                return false;

            }

            // the chars are "equal", so proceed to check the next pair

        }



        // we came to the end of either (or both) strings, left is "smaller" if it was shorter:

        return li == lhs.end() && ri != rhs.end();

    }



    uint8_t ByteToColor( const int byte )

    {

        switch ( byte ) {

        case 0:

            return Color::BLUE;

        case 1:

            return Color::GREEN;

        case 2:

            return Color::RED;

        case 3:

            return Color::YELLOW;

        case 4:

            return Color::ORANGE;

        case 5:

            return Color::PURPLE;



        default:

            break;

        }



        return Color::NONE;

    }



    int ByteToRace( const int byte )

    {

        switch ( byte ) {

        case 0x00:

            return Race::KNGT;

        case 0x01:

            return Race::BARB;

        case 0x02:

            return Race::SORC;

        case 0x03:

            return Race::WRLK;

        case 0x04:

            return Race::WZRD;

        case 0x05:

            return Race::NECR;

        case 0x06:

            return Race::MULT;

        case 0x07:

            return Race::RAND;



        default:

            break;

        }



        return Race::NONE;

    }

}

Could be that you receive nulls in lhs and rhs.
Did you check that parameters?

i'm really tired...

@afxgroup

I am still a beginner in C++.

There is no mention lhs or rhs anywhere in the code..

You should see where CaseInsensitiveCompare is called and see what is passed to the function

i'm really tired...

I'm stuck with this error
"Expection 'basic_sting::M_create' occured during application time
when running the game.
If anyone wants to check the sources.
Here it is

Just can't stay away

@SinanSam460

basic_string sources are in gcc:include/c++. You might be able to generate a stack trace by inserting asm("trap"); inside M_create before throw. I suppose the file is basic_string.tcc.

You should then rebuild your binary with debug flags, like -gstabs. You can build a helloworld app first, add trap there and test what you get.

EDIT: changed debug flag.
