开发平台(Platform): (Ex: Win10, Linux, ...) Linux
编译器(Ex: GCC, clang, VC++...)+目标环境(跟开发平台不同的话需列出) g++

上面网址是我程式码 ...
g++ AbstractOptimizationProblem.cpp main.cpp
我程式马里面有用到 template 但是我不太熟template ！ 懂的朋友可以帮我看一下原因！
Thanks
下面是错误讯息
/tmp/ccQ0iTvh.o: In function
`LocalLeastSquaresProblem::LocalLeastSquaresProblem(int, int,
ConvergenceChecker<Evaluation>*)':
main.cpp:(.text+0x28): undefined reference to
`AbstractOptimizationProblem<Evaluation>::AbstractOptimizationProblem(int,
int, ConvergenceChecker<Evaluation>*)'
/tmp/ccQ0iTvh.o:(.rodata._ZTV24LocalLeastSquaresProblem[_ZTV24LocalLeastSquaresProblem]+0x10):

AbstractOptimizationProblem.h:10:5: error: initializespecified for non-virtual method改成 = 0 编译变成这样错误

把constructor 设为pure virtual functionAbstractOptimizationProblem(int maxEvaluations, int maxIterations, ConvergenceChecker<PAIR>* checker<PAIR>* checker)=0;

讲错了= =" sorry这样好像可以了~ https://pastebin.com/x7csU8Cd原因是compiler不知道template class要支持什么dataas the compiler does not know, while compiling Stack.cpp by itself, the data types it should providesupport for.来源:https://tinyurl.com/y7qlx77b

嗯嗯～有部份错误有解！ 不过 main.cpp:(.text+0x28): unAbstractOptimizationProblem<Evaluation>::AbstractOpti::AbstractOptimizationProblem(int, int, ConvergenceCh我在main.cpp 把 AbstractOptimizationProblem(maxEvalua改成 AbstractOptimizationProblem<Evaluation>(maxEvalu
