Thread: how to solve linker error

hi ,

when i am trying to execute a c file,it is compiling fine with zero errors but having 4 warnings.

when i am trying execute the option make the exe file, it results linker error:undefined symbol.

There are 26 such type of errors.

In the c file it is accessing about 7 user defined header files.

Earlier i noted that for all these header files ,corresponding objects were not creating.

so i loaded each header files compiled them resulted creation of their object files.

but when executing the c file,still there remains linker errors.

guide me to resolve this issue.

Thanks and Regards

hi,

when i am trying the compile option ->Make exe file

results the following linker errors.

Totally there are 26 such type error.

i have gone through some header files.

The symbol which it results errors(like 'rr_malloc') are functions in header files.

Linker Error: Undefined symbol '_rr_malloc' in module LMCO.C
Linker Error: Undefined symbol '_rr_calloc' in module LMCO.C
Linker Error: Undefined symbol '_NewArray' in module LMCO.C
Linker Error: Undefined symbol '_DeleteArray' in module LMCO.C
Linker Error: Undefined symbol '_new_index' in module LMCO.C
Linker Error: Undefined symbol '_sih_lookup' in module LMCO.C
Linker Error: Undefined symbol '_show_dot' in module LMCO.C
Linker Error: Undefined symbol '_calc_prob_of' in module LMCO.C

Hopefully (fingers crossed) you don't have any functions in your header files. You should have a prototype of your functions in your header files, and the functions themselves in a source file somewhere. That source file needs to be in your project.
