我目前正在编写一个仅包头的包装器库,它应该提供对某些FORTRAN代码的C访问.但我坚持’未定义的引用(…)’

我必须说我有点惊讶,因为我使用这个FORTRAN例程在C中编译了我自己的函数,没有任何问题.

也许关于结构的几句话.该库遵循单例模式,但没有用户实例化库的可能性.因此,用户的唯一入口点是静态方法MultiNestWrapper :: Wrapper< T> :: run(). MultiNestWrapper是命名空间,Wrapper< T>是一个模板化的类(因此,将来您可以对如何选择执行计算的类型影响结果和性能进行基准测试). FORTRAN例程在此命名空间之外声明,如

extern "C" {
  extern void __nested_MOD_nestrun(int *, int *, int *, double *, double *, int *, int *, int *, int *, int *, double *, const char *, int *, int *, int *, int *, void (*Loglike)(double *, int *, int *, double *), void (*dumper)(int *, int *, int *, double **, double **, double *, double *, double *), int *context);
}

我称之为

__nested_MOD_nestrun(&_mmodal, &_ceff, &_nlive, &_tol, &_efr, &_ndims, &_nPar, &_nClsPar, &_maxModes, &_updInt, &_Ztol, _root, &_seed, _pWrap, &_fb, &_resume, internalLogLike, internalDumper, &_context);

参数的类型匹配.

当我尝试编译它时,我收到以下错误：

[dare2be@schroedinger multinest-interfejs]$make all
g++ -c ExampleLibMnCpp.cpp -o ExampleLibMnCpp.o
gfortran -lstdc++ -llapack -lblas -lnest3 -L/usr/local/lib ExampleLibMnCpp.o -o ExampleLibMnCpp

make: *** [ExampleLibMnCpp] Error 1

但是,请注意

[dare2be@schroedinger multinest-interfejs]$nm /usr/local/lib/libnest3.a | grep __nested_MOD_nestrun
000000000001e0f0 T __nested_MOD_nestrun

我自己总是处理那些未定义的引用.但现在我无法绕过这个.我指定-lnest3 -L /usr/local/lib explicite和/usr/local/lib/libnest3.a包含链接器抱怨的例程…请帮助一个兄弟！
