I'm verry new at elastix and stuck at the verry beginning. I'm trying to compile a verry basic program in C++ that will make an instantiation of the using elastix library. When I tried to compile the program, I got a linker error:
Error LNK2019: external symbol "public: virtual __cdecl elastix
ELASTIX :: :: ~ ELASTIX (void)" (?? 1ELASTIX @ elastix FALU@@@XZ)
unresolved referred to in the "public function: virtual void * __cdecl
elastix eLASTIX :: :: `scalar deleting destructor '(unsigned int)" (??
_ @ elastix GELASTIX UEAAPEAXI@@@Z)
I' ve done some googeling and found that it is infact a popular linker problem: see this topic and this one and this particular elastix mail chain. I tried to fix it using these links but without succes. I'm wondering if you guys/girls could help me out. below you can find my source files (CMakeList.txt and C++ code) and some additional information: I run windows 7, Cmake version is 3.0.2, ITK version is 4.6, elastix version is 4.7 and Microsoft VS 2008. Thanks in advance
