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

Post your compiler command line and actual linker error messages (well some of them at least).

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.

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.
