crash running latest MapSplitter?

Hi,
First of all, great work on PLSM! The demo is impressive and I'm working towards integrating it with my latest project.

I downloaded the latest source out of CVS this morning and following the Wiki instructions I'm trying to run MapSplitter when I get a crash.

It appears that in MapUtil::LoadDataFromSource() there is a new
PagingLandScapeData2D_HeightField created with a NULL PagingLandScapeData2DManager. The crash occurs when trying to access a null mParent member in the PagingLandScapeData2D_HeightField constructor.

This is the call stack:
> Ogre::PagingLandScapeData2DManager::getOptions() Line 113
Ogre::PagingLandScapeData2D_HeightField::PagingLandScapeData2D_HeightField(Ogre::PagingLandScapeData2DManager * dataMgr=0x00000000) Line 55
Ogre::MapUtil::LoadDataFromSource() Line 480
Ogre::MapUtil::processOneMap() Line 525
Ogre::MapUtil::process() Line 335
main(int argc=1, char * * argv=0x003d80d0) Line 48
__tmainCRTStartup() Line 586
mainCRTStartup() Line 403

This being my first build of PLSM, its not unforseable that I'm missing something. Anyway, hope this helps,
Thanks!

CVS bug.
I'll look after that asap.
Thanks to point that out.

Seems that the bug may take time to fix, so... Note that you can use demo mapslitted files wiht CVS plsm2 plugin.

fixed in CVS.

Hello again,
when i run MapSplitter i'm getting a seg fault:

I hope this infos helps . thx,

If you can give me the value of "filename" in the call stack it would help a lot.
I'll look that asap.


(gdb) print filename
$1 = (const String &) @0x80a5040: {static npos = 4294967295, _M_dataplus = {<std::allocator<char>> = {<No data fields>},
_M_p = 0x87285ec "ps_height_1k.png"}, static _S_empty_rep_storage = {0, 0, 0, 0}}


(gdb) print Heightdata
$2 = (Real *) 0x41df5008

(gdb) print Heightdata[0]
Cannot access memory at address 0x41df5008


Thanks.
Looking at it.

Fixed in CVS.
