[FlopCpp] FlopCpp with glpk

[Marcos Roberto Silva]

Hi.

I'm trying to solve a problem using glpk as a solver. I changed the
Makefile provided in the "example" folder of FlopCpp
("FlopC++-1.1.2/FlopCpp/examples").

I changed the following lines in the Makefile:

##########################################################################
#    You can modify this example makefile to fit for your own program.   #
#    Usually, you only need to change the five CHANGEME entries below.   #
##########################################################################

# To compile other examples, either changed the following line, or
# add the argument EXNAME=example_name to make
EXNAME = usahlp

# CHANGEME: This should be the name of your executable
EXE = $(EXNAME)

# CHANGEME: Here is the name of all object files corresponding to the source
#           code that you wrote in order to define the problem statement
OBJS =  $(EXNAME).o

# CHANGEME: Additional libraries
ADDLIBS = -L/home/marcos/Downloads/pacotes/FlopC++-1.1.2/Osi/lib/ -lOsiGlpk
-lOsi -lglpk

# CHANGEME: Additional flags for compilation (e.g., include flags)
ADDINCFLAGS = -I../../include
-I/home/marcos/Downloads/pacotes/FlopC++-1.1.2/Osi/src/OsiGlpk

# CHANGEME: Directory to the sources for the (example) problem definition
# files
SRCDIR = .

I can compile and link the program, but when I try to execute the program I
get the following error:

Could you please help me to solve this problem? I don't understand why the
library is not found.

Thank you.
