I am getting very frustrated, as I am out of practice with my C++. I'm
having particular trouble with the make utility. I THINK I'm doing this
right. I have four modules, one with a class (IniUtils.h & .cpp), two with
functions (StringUtils.h & .cpp and FileUtils.h & .cpp), and one with a
"main" function to test them (IniTest.cpp). I've included my Makefile. I
won't include the other files (I will post them as replies). But I will say
that IniUtils requires StringUtils and FileUtils, StringUtils requires
FileUtils, FileUtils requires StringUtils, and IniTest is only testing
IniUtils (its IniFile class), so it only includes IniUtils.h.

*Makefile*

OBJS = IniTest.o IniUtils.o StringUtils.o FileUtils.o
EXES = initest.exe

CXX = redir -o gcc.log -eo gxx
CXXFLAGS = -g -Wall
ERR =

$(EXES): $(OBJS)
 $(CXX) $(CXXFLAGS) -o $(EXES) $(OBJS) $(ERR)

IniTest.o: IniTest.cpp IniUtils.h StringUtils.h FileUtils.h
 $(CXX) $(CXXFLAGS) -c IniTest.cpp $(ERR)

IniUtils.o: IniUtils.cpp IniUtils.h
 $(CXX) $(CXXFLAGS) -c IniUtils.cpp $(ERR)

StringUtils.o: StringUtils.cpp StringUtils.h
 $(CXX) $(CXXFLAGS) -c StringUtils.cpp $(ERR)

FileUtils.o: FileUtils.cpp FileUtils.h
 $(CXX) $(CXXFLAGS) -c FileUtils.cpp $(ERR)

clean:
 del *.o

Here's the error message from gcc.log:

IniTest.o: In function `main':
IniTest.cpp:1: undefined reference to `IniFile::IniFile(char *)'
IniTest.cpp:2: undefined reference to `IniFile::setActiveSection(char *)'
IniTest.cpp:3: undefined reference to `IniFile::getValue(char *)'

If anyone can help, I'd appreciate it. You can email or post here. =)

Morpheus.
