C++ & nmk problem

[taurean]

I have two directories named dir1 & dir2; correspondingly dir1.nmk &
dir2.nmk;

i place A.h & A.cpp in dir1 and update dir1.nmk with both cpp & .h files
so that it can be accessed from other directories too.

If I try to access the files from within another cpp file within dir1 and
it works fine: compiling & runs.

if I try to access from one of the cpp files from dir2, i have linker
errors.

plz update me what shall be done. any input is appreciated!!
