Makefile:13: recipe for target 'CCEH_LSB' failed
make: *** [CCEH_LSB] Error 1

[yige-hu]

make CCEH_MSB works. But not LSB. The issue is caused by inconsistent definition and initialization of dir in class CCEH. In CCEH.h and MSB.cpp, dir is defined as Directory* dir. While in CCEH_MSB.cpp, dir is supposed to be defined as Directory dir.
