undefined reference - so I have to edit the Makefile?

I have a large amount of code, so I have tried to only include the relevant parts of the code here

I have a header file called "ASp.h"

Code:

namespace ASP

{

    class ASp

    {

        public:

            ASp();

            ASp(FILE* fp);  

            void T_B_P_N(const char* type, int num);

    }

}

another header file "ms.h"

Code:

bool aSpQ(int argc, char* argv[]);

a cpp file "ms.cpp"

Code:

bool aSpQ(int argc, char* argv[])

{

    if(argc != 7)

    {

        usageASpQ();

        return false;

    }

    FILE* input = fileRead(argv[3]);

    string type = string(argv[4]);

    int num = atoi(argv[5]);

    FILE* output    = fileWrite(argv[6]);

    ASp* asp = new ASp(input);

    asp->T_B_P_N(type.c_str(), num);



    for(int i = 0; i < asp->numtr; i++)

    {

        asp->fs[i]->print(output);

    }

    fclose(input);

    fclose(output);

    return true;

}

Those files compiled with no problems when they were included in another cpp file.

I have another file called "PBL.cpp". This compiled fine before, until I tried to include the files above in PBL.cpp

Code:

#include "ASp/ASp.h"



using namespace ASP;

using namespace std;



//bunch of code



bool aSpQ(char * fname_r, string type, int num, char * fname_q)

{

    FILE* input = fileRead(fname_r);

    FILE* output    = fileWrite(fname_q);



    ASp* asp = new ASp(input);

    asp->T_B_P_N(type.c_str(), num);



    for(int i = 0; i < asp->numtr; i++)

    {

        asp->fs[i]->print(output);

    }

    fclose(input);

    fclose(output);

    return true;

}

When I try to compile this, at the line of

Code:

ASp* asp = new ASp(input);):

in the PBL.cpp file

I get the following errors:
I get errors of undefined reference to ASP::ASp::ASp(_IOFILE*) and undefined reference to ASP::ASp::T_B_P_N(char const*, int)

But

Code:

ASp* asp = new ASp(input);

was written in ASp.cpp and

Code:

ASp::T_B_P_N(char const*, int)

was written in another file

Is there a linkage error? Do I need to make changes in the makefile? How do I get the linker to link against the ASp.cpp file? I am new to using Unix

you need to post how do you compile (the commands you use or the makefile)

That actually looks like a link error... The library containing the definitions/functions was missing.

My coworker told me the problem is probably with the directories and libraries that are written in CMakeLists.txt. He tried to help briefly, but now he says that he can't help anymore

I have included the relevant parts of the CMakeLists to see if anyone can help

in /ws/larryburns/cmake/ME/Build/sc/ME/CMakeLists.txt:

Code:

SET(ME_LINK_LIBS 

  MEAPI

  InLJ

  InEl

  El

  LJ

  PE

  CP

  GOAFT

  ASp

  LB

  Con

)



SET(ME_LINK_LIBS ${ME_LINK_LIBS}

  Blu

  DPG

  PP 

  MEU

  SVD

  VFT

  GFT

  Geo

  Cur

  Con

  BO

  UM

  ${O_LIBRARY}

  l4c

#  GL

#  GLU

)

and in /ws/larryburns/cmake/ME/Build/sc/CMakeLists.txt:

Code:

ADD_SUBDIRECTORY (Ut)

ADD_SUBDIRECTORY (ASp)

ADD_SUBDIRECTORY (LB)

ADD_SUBDIRECTORY (Con)

ADD_SUBDIRECTORY (El)

ADD_SUBDIRECTORY (LJ)

ADD_SUBDIRECTORY (InLJ)

ADD_SUBDIRECTORY (InEl)

ADD_SUBDIRECTORY (MEU)

ADD_SUBDIRECTORY (PE)

ADD_SUBDIRECTORY (GB)

ADD_SUBDIRECTORY (GOAFT)

ADD_SUBDIRECTORY (CP)

ADD_SUBDIRECTORY (MEAPI)

ADD_SUBDIRECTORY (Blu)

ADD_SUBDIRECTORY (DPG)

ADD_SUBDIRECTORY (PP)

ADD_SUBDIRECTORY (UM)

ADD_SUBDIRECTORY (Geo)

ADD_SUBDIRECTORY (GFT)

ADD_SUBDIRECTORY (Con)

ADD_SUBDIRECTORY (BO)

ADD_SUBDIRECTORY (Cur)

ADD_SUBDIRECTORY (l4c)

As can be seen, even when I add ASp in both CMakeLists as a subdirectory and library, but I still get the undefined reference errors
