Forte Compiler 12 with RougeWave

Aug 29, 2014 at 7:28pm

Hi ,
we are existing moving application from solaris 8 to solaris 10
I am using Rougewave RW_Tools version 10
i have some std::ifstream classes used in the source code
when i compile it give me the fllowing warnings and teh linker does not report any error but fails to install

ld: warning: symbol `RWDlistCollectables::__vtbl' has differing sizes:
(file /xenv/rwsp_tools/X/10.0/32/core1000_12d/lib/libtls8012d.so value=0x98; file /xenv/Forte/X/12.0/5.10u1/lib/rw7/std/librwtool.so value=0x88);
/xenv/rwsp_tools/X/10.0/32/core1000_12d/lib/libtls8012d.so definition taken
ld: warning: symbol `RWCollectableInt::__vtbl' has differing sizes:

in the source code we are using std classes and certainly i can see that there is library conflict .

if i remove RougeWave library libtls8012d.so then i get
int RWCString::compareToSpecial(const char*,unsigned,RWCString::caseCompare)const /BuildDir/ProdBuildDir/acctdist_1261617/hermebld/acctdist_3.7_Q0_TST/lib/libACDist.a(Db.o)
unsigned RWCString::indexSpecial(const char*,unsigned,unsigned,RWCString::caseCompare)const /BuildDir/ProdBuildDir/acctdist_1261617/hermebld/acctdist_3.7_Q0_TST/lib/libACDist.a(Db.o)

if i remove -library=rwtools7_std then i get teh above warnings and teh linker fails without any errors or warnings

please help me with this.

I haven't used Tools.h++ for a while, but my first guess is that you're mixing code built on the new environment with libraries built on the old environment.

I don't think you'll find anything wrong in the code or build.

Clean everything and start again.

I too haven't used them in a long time; however, I do remember upgrading Roguewave and not cleaning everything was the issue.

Also, check the directories for pre-instantiated objects.

Another thing to check: make sure you're getting the RogueWave header files from the same place in all your code.

see the Conflict is between libraries from /xenv/rwsp_tools/X/10.0/32/core1000_12d/lib/libtls8012d.so
versus
libraries from Forte

/xenv/Forte/X/12.0/5.10u1/lib/rw7/std/librwtool.so

so how to remove and which one to remove ?

Try removing the rwsp_tools version from the link line. It sounds like this mihgt be an older version.

ok i removed its compiling without errors but stilll there seems a linker error
for which there is no error message

i have a doubt on the following code

is there anything wrong in declaration and definition which is causing the linker error ?

there seems a linker error for which there is no error message

Can you elaborate on this? What makes you say there is a linker error?

int ACColumnInfo::operator++()
{
 ...
      column = column_list_ptr->at(index);

The at(n) method of a list is very inefficient: it has to start at the beginning of the list and walk through it until it finds the n'th element. You might be better off mapping to a vector, unless the number of items in the list is very small.

In fact, it looks like it would be pretty easy to convert this code to use STL collections, if that's an option.

i removed the conflicting libraries the code compiler but does not install the application , this makes me believe that there is a linker error
and there are no linker errors displayed
the only code change i made is the about
i added template declaration

template <class K, class T, class H, class EQ ,class A > class RWTValHashMap58 :

				RWTValHashMap< K, T,H,EQ,A>() { }
		};

then in declaration of ACColumnInfo i changed 

#if CPLUSREL >= 6
      RWTValHashMap58<RWCString,RWTValSlist<Column> *,str_hash,StringEqual> *dictionary;
#else
      RWTValHashMap<RWCString,RWTValSlist<Column> *,str_hash,StringEqual> *dictionary;
#endif


then in ACColumnInfo

   RWTValSlist<Column> *list_ptr;

#if CPLUSREL >= 6
   RWTValHashMapIterator58<RWCString,RWTValSlist<Column> *,str_hash,StringEqual> iterator(*dictionary);
#else
   RWTValHashMapIterator<RWCString,RWTValSlist<Column> *,str_hash,StringEqual> iterator(*dictionary);
#endif
   // iterate through every object



so my question is is there any problem in declaration and definition
?
cold it be this which is causing linker error ?
Sep 9, 2014 at 4:37pm
dhayden (5799)
I'd dig through the output of the make process to see if there is an error displayed. There must be some reason why it didn't install the program and there must be an error message there somewhere.
