Hi,

I encountered this error in compiling Dynare from source (4.2.0)

[quote]…/…/…/…/dynare++/sylv/cc/SylvParams.cpp: In member function ‘mxArray\* SylvParams::DoubleParamItem::createMatlabArray() const’:  
…/…/…/…/dynare++/sylv/cc/SylvParams.cpp:136: error: ‘mxCreateScalarDouble’ was not declared in this scope  
make[2]: \*\*\* [libdynare\_\_\_a-SylvParams.o] Error 1  
make[2]: Leaving directory `/stat-home/lombard/gianni/dynare-4.2.0/mex/build/matlab/libdynare++' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory`/stat-home/lombard/gianni/dynare-4.2.0/mex/build/matlab’  
make: \*\*\* [all-recursive] Error 1  
[/quote]

the mex for qz seemed to have been produced. Compiling the sylvester solver has failed.

Any clue about the possible cause?

Thanks and best

Gianni

Hi,

I’ve compiled version 4.2.4 on Red Hat without encountering the above mentioned problem.

Best
