need help on g++ linking

[Zhifeng Li]

Dear All:

I was trying to link the my codes with some libraries using g++ compiler.
Unfortunately, I got the following linking error. Could anyone share some
experience or suggestion? Thank you very much. The linking error follows.

g++  -static -g -Wall -pedantic -I/home/kuhn/zhifeng/Lib1/include
-I/meas/lib/ilog/cplex81/include parameters.o LinearEqMatrix.o Memory.o
