I get two rather cryptic errors when I try to compile some of my own software. In the first, the software links fine normally, but when I try to add debug information with the -g switch, I get the following error or something similar:
$ make g++ -I/home/Petey/include -Wno-deprecated -g -o model1 model1.cc -L/home/Petey/lib -ldataset-g -lpetey -lsparse-g -lgsl -lgslcblas /tmp/cc5e9G8Z.o: In function `_ZN7datasetD0Ev': /home/Petey/include/simple_temp.h:(.dtors+0x0): undefined reference to `global destructors keyed to x_grid' /home/Petey/lib/libdataset-g.a(simple_temp-g.o): In function `_ZN6simpleIdEeqIdEEiRKS_IT_E': /home/Petey/my_software/datasets/simple_temp.cpp:(.dtors+0x0): undefined reference to `global destructors keyed to _ZN6simpleIfE8set_typeEv' collect2: ld returned 1 exit status make: *** [model1] Error 1 (I create multiple versions of the libraries by appending the optimization flag, e.g. -g, -O2 etc.) The second error, and the simpler-looking of the two, is as follows: g++ -I/home/Petey/include -Wno-deprecated -O2 -o model2 model2.cc traj_int_obj.o tcoord_defs.o -L/home/Petey/lib -ldataset-O2 -lpetey -lsparse-O2 -lgsl -lgslcblas model2.cc: In function `int main(int, char**)': model2.cc:140: warning: converting to `long int' from `double' traj_int_obj.o:traj_int_obj.cc:(.text+0x12): undefined reference to `_mcount' traj_int_obj.o:traj_int_obj.cc:(.text+0x6f): undefined reference to `_mcount' traj_int_obj.o:traj_int_obj.cc:(.text+0x165): undefined reference to `_mcount' traj_int_obj.o:traj_int_obj.cc:(.text+0x212): undefined reference to `_mcount' traj_int_obj.o:traj_int_obj.cc:(.text+0x382): undefined reference to `_mcount' traj_int_obj.o:traj_int_obj.cc:(.text+0x702): more undefined references to `_mcount' follow There is no variable or function called "mcount" in traj_int_obj.cc. The only external header I use is stdio.h so it must be somehow connected. Any help anyone could offer would be greatly appreciated.
