Problem


When linking the Math.h++ on SGI, undefined symbols result:

 

NCC -I.. -O2 -o example1 example1.o -L../lib ../lib/librwmth.a -lrwlaf -lrwbla -lm -lcomplex
ld:
Unresolved:
dot(const RWMathVec&,const RWMathVec&)
l1_norm(const RWMathVec&,double&)
linf_norm(const RWMathVec&,double&)
RWAllocBlock>::RWAllocBlock >(unsigned int)



Cause


This is a result of some template instantiation files used when building the Math.h++ library not being included in the math library librwmth itself.


Action


For SGI this can be fixed by compiling the library with the -ptused option. Append the -ptused option to the CPPOPTIONS in the files mathsrc/makefile.

For more information on template instantiation, please see our C++ FAQ.
