A compilation problem when using templates

Hello life savers,

I'm having trouble compiling a specific program. The program was originally written for gcc and was compiled successfully under it. When trying to compile under Solaris 11, I get this error:

"Hashtable.h", line 170: Error: Could not find a match for hash needed in Hashtable<long long, Orderbook*>::get(long long).
"ReferenceData.cpp", line 59: Where: While instantiating "Hashtable<long long, Orderbook*>::get(long long)".
"ReferenceData.cpp", line 59: Where: Instantiated from non-template code.


line 170 of file "Hashtable.h" is:
int tIndex = (hash(pKey,mSize));

(line 59 of "ReferenceData.cpp" is using it).


The "hash" functions are global, and are defined as followed:

static int hash( int64 pValue, int pMod )
{
int tValue = (int) (pValue & 0x7FFFFFFF);
return (tValue % pMod);
}

static int hash( int pValue, int pMod )
{
return (pValue % pMod);
}

static int hashString( const char *pStr, int pMod )
{
int tLen = (int) strlen( pStr );
unsigned int hash = 0;
unsigned int x = 0;

for(int i = 0; i < tLen; pStr++, i++)
{
hash = (hash << 4) + (*pStr);
if((x = hash & 0xF0000000L) != 0)
{
hash ^= (x >> 24);
}
hash &= ~x;
}

return (int) (hash % pMod);
}

static int hash( const std::string *pStr, int pMod )
{
return hashString( pStr->c_str(), pMod );
}

static int hash( const char *pStr, int pMod )
{
return hashString( pStr, pMod );
}


Please tell me if the pasted code is enough or you need the entire class code for finding what's wrong (didn't want to paste the whole thing. it's long....).


Thanks a lot.
yp515.

NAME
debconf-mergetemplate - merge together multiple debconf template files SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program. This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified files will be read in, merged, and output to standard output. This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the english versions of the fields they translated, for their reference. So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the main file (which might be more up-to-date). This program handles that case properly, just list each of the translated templates files, and then your main templates file last. OPTIONS
--outdated Merge in even outdated translations. The default is to drop them with a warning message. --drop-old-templates If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire template. SEE ALSO
