Hello! I'm an italian guy student so sorry for my BAD english!
I need your help about the Coin-All project.

I'm trying to use a project made by my Prof. This is his the makefile, edited by me for my system (I'm using Ubuntu 12.04):

# module name
NAME = cwl2

# switches
SW = -O3 -g

# COIN base directory
COINDIR = /home/luca-kun/Desktop/LOG/coin-All/

# Osi libreries
OSIINC = -I$(COINDIR)include/coin/
OSILIB = -L$(COINDIR)lib/-lOsiCbc -lOsiClp -lClp -lOsi -lCoinUtils
                         

# libreries
# mac version
#LIB = $(OSILIB) -lm -framework vecLib
# standard version
 LIBS_PATH = $(OSILIB) -llapack -lm

# compiler
CC = g++

# default target- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

default: $(NAME)

# clean - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

clean::
	rm -f *.o *~ $(NAME)

# main module (linking phase) - - - - - - - - - - - - - - - - - - - - - - - -

OBJ =   cwl2.o

$(NAME): $(OBJ)
	$(CC) -o $(NAME) $(OBJ) $(LIBS_PATH) $(SW)

# dependencies: every .o from its .C + every recursively included .h- - - - -

cwl2.o: cwl2.cpp
	$(CC) -c $*.cpp -o $`@` $(OSIINC) $(SW)

When I tried to compile the project for the first time, it returned those errors:

luca-kun`@`ubuntu:~/Desktop/LOG/cwl2$ make
g++ -c cwl2.cpp -o cwl2.o -I/home/luca-kun/Desktop/LOG/coin-All/include/coin/ -O3 -g
g++ -o cwl2 cwl2.o -L/home/luca-kun/Desktop/LOG/coin-All/lib/-lOsiCbc -lOsiClp -lClp -lOsi -lCoinUtils -llapack -lm -O3 -g
/usr/bin/ld: cannot find -lOsiClp
/usr/bin/ld: cannot find -lOsi
collect2: ld returned 1 exit status
make: *** [cwl2] Error 1
luca-kun`@`ubuntu:~/Desktop/LOG/cwl2$ 

So, roughly , I copied all the libraries in the Osi and Clp projects and pasted in the /usr/lib directory.

After that, there was no errors during compilation.

But, if I try to run the program (I'm sure that the instance file small.txt is correct), I have this error:

luca-kun`@`ubuntu:~/Desktop/LOG/cwl2$ ./cwl2 data/small.txt
Solving instance data/small.txt with 4 warehouses and 10 customers
GMPL not being used �Z� (null) no
Aborted (core dumped)
luca-kun`@`ubuntu:~/Desktop/LOG/cwl2$  

Searching on Google, I discovered that this an error message in CoinUtils/src/CoinMpsIO.cpp. I don't really understand what is wrong...

Again, sorry for my english.

Regards!

Ps: I made a ticket in Utils Project section because I didn't find a "Coin-All" project area...and because the error message is in coin-Utils file.

The linking problem was probably caused by a missing space before -lOsiCbc in OSILIB. The other thing I have no idea how to reproduce.
