gcc linking: undefined reference to just about everything


I have a horrendous problem linking a c++ application I am `developing.'
This has something to do with pure abstract classes, virtual inheritence,
destructors, polymorphism, all the big words. The classes appear to
compile correctly, but in the link phase, i get a lot of errors. admittedly
it appears to be the same error repeated for many of the classes:

b::symLinear::~symLinear [in-charge]()'

[snip]

plus many more lines. this is under
gcc version 3.3.5-20050130 (Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1)

from what i've found on the net `in-charge' refers to constructor, and `not-in-charge'
to a destructor. i've seen other people with errors like this, but they were all compiling other's code and had not included linker flags to the correct libraries. i don't think this is my problem, because it appears that i can link things correctly in subdirectories of this project. (oh, yes there are two subdirectories.) i can provide a tgz file with my code and makefile if necessary. any help appreciated!


thanks,

Are you compiling using g++ or gcc? If gcc, you should be using g++, which is the GNU C++ compiler. gcc is the C compiler and doesn't link any of the C++ libraries by default.

i am using g++ to link

the command which attempts the link is

g++ -o test -L/usr/local/lib -L. -L/usr/X11R6/lib -L/usr/qt/3/lib -Lgeometric/ test.o angle.o basedefs.o centered.o curve.o
dist.o dseg.o exceptions.o linear.o line.o obj.o point.o qbez.o quadratic.o quant.o radial.o ray.o straight.o transform.o ve
c.o circular.o circle.o geometric/geometric.o numeric/numeric.o -lplotter -lXaw -lXmu -lXt -lXext -lX11 -lm -lqt -lSM -lICE
-lc -lm -lz -lstdc++ -v

this is from my makefile. i use the same makefile stub in this dir and a subdir. i am able to get the subdir files compiled and executable. something else is going wrong here, i think....

Is g++ also used for the compilation of the objects or just the linker step? Maybe some sort of name mangling issue?

g++ is used throughout the compilation process. here's a sample from make -n:

Name mangling is what C++ does to functions to support overloaded functions, etc. It's basically the reason you usually need to define functions compiled as see using extern "C".

If you are usgin g++ throughout, it isn't likely the problem, it was just something I was speculating on because I was out of any other ideas...

Is the patlib namespace your own, or is that from another library that you maybe aren't including in the linker parameters?

patlib namespace is what i am developing. all of my stuff appears to be inside
this namespace.

i am wondering if there is some special flag i have to set for the compiler to know not
to mangle names so badly, or to be pedantic or something.

i also just emerged the latest and greatest gcc, so the problem may just go away
(i doubt it...)

Despite the way it sounds, "name-mangling" isn't really a bad thing. It just refers to the way a C++ compiler adds decorations to a function to uniquely identify it. About the only time it is a potential problem is when mixing C and C++. Since you are using a C++ compiler for each step, it shouldn't be a problem.

Are you using template classes at all? It doesn't appear so from the errors, but using templates can cause linker problems if you try to separate the implementation from the header like you usually do with normal classes. With templates, the compiler has to know the full implementation at the time it does each compilation unit, so you generally need to put the full implementation in the header.
