what should be done to bind functions that are not in rtklib.h?

[zvictorliu]

fucnctions like rescode, valsol are not declared in rtklib.h

Now I am trying to bind them, however it seems a linker problem occurred:

ImportError: /home/<user>/miniconda3/envs/py39/lib/python3.9/site-packages/pyrtklib-0.2.5-py3.9-linux-x86_64.egg/pyrtklib/pyrtklib.so: undefined symbol: _Z7rescodeiPK6obsd_tiPKdS3_S3_PKiPK5nav_tS3_PK8prcopt_tPdSC_SC_SC_PiSC_SD_

I have those modification:

in pyrtklib.cpp:

m.def("rescode", static_cast<int (*)(int iter, const obsd_t *obs, int n, Arr1D<double> Srs,
                   Arr1D<double> Sdts, Arr1D<double> Svare, Arr1D<int> Ssvh,
                   const nav_t *nav, Arr1D<double> Sx, const prcopt_t *opt,
                   Arr1D<double> Sv, Arr1D<double> SH, Arr1D<double> Svar, Arr1D<double> Sazel, Arr1D<int> Svsat,
                   Arr1D<double> Sresp, int *ns)>(&rescode), "rtklib rescode");

extern int rescode(int iter, const obsd_t *obs, int n, Arr1D<double> Srs,
                   Arr1D<double> Sdts, Arr1D<double> Svare, Arr1D<int> Ssvh,
                   const nav_t *nav, Arr1D<double> Sx, const prcopt_t *opt,
                   Arr1D<double> Sv, Arr1D<double> SH, Arr1D<double> Svar, Arr1D<double> Sazel, Arr1D<int> Svsat,
                   Arr1D<double> Sresp, int *ns)
{
    const double *rs = Srs.src;
    const double *dts = Sdts.src;
    const double *vare = Svare.src;
    const int *svh = Ssvh.src;
    const double *x = Sx.src;
    double *v = Sv.src;
    double *H = SH.src;
    double *var = Svar.src;
    double *azel = Sazel.src;
    int *vsat = Svsat.src;
    double *resp = Sresp.src;
    auto tmp = rescode(iter, obs, n, rs, dts, vare, svh, nav, x, opt, v, H, var, azel, vsat, resp, ns);
    return tmp;
}

in rtklib.h

EXPORT int rescode(int iter, const obsd_t *obs, int n, const double *rs,
                   const double *dts, const double *vare, const int *svh,
                   const nav_t *nav, const double *x, const prcopt_t *opt,
                   double *v, double *H, double *var, double *azel, int *vsat,
                   double *resp, int *ns);

in pntpos.c

static -> extern

Hi, sorry for the late reply. I copied your code, but it seems work well.

Theoretically, if there's something wrong with the linking process, the compile should not pass, unless you use the dynamic library mode. So, do you switch on the LIBRARY option in CMakeLists.txt? Could you provide more details?

[zvictorliu]

Thanks! I don't exactly know the reason but now it seems work well after re-buiding.

Anyway, thanks for your reply

Good job. If you have any more questions, feel free to contact me.
