Compiling in Linux&Eclipse when I can compile from terminal

Question

So I was finally able to download an old version of webkit and compile it (after fixing 100 errors) in the terminal using the classic:

./configure
make

Now since I have the source of the program, my goal is to debug it (setting breakpoints on the C++ code and stuff). Since I'm using Linux for the first time here I downloaded eclipse to have an intuitive GUI. However, when I import the project I can't seem to be able to compile it. Include errors are everywhere and I cannot solve them no matter how much I try.

How can I compile it in eclipse when I can do it in the terminal? Also, is there another approach to debug the program?

Thanks a lot!

Ok so I managed to compile and link the code so that it could be loaded into gdb with symbolic debugging info as follows :

1. I downloaded and extracted http://webkitgtk.org/releases/webkitgtk-2.0.4.tar.xz
2. I ran ./configure and manually did apt-get install (or in the case of ICU downloaded and compiled) all required dependencies.
3. I then made the following modifications to the GNUmakefile adding -ggdb to each of the vairable global_cppflags global_cflags and global_cxxflags (In an effort to speed up the build I removed all warning flags from the cppflags, not sure it made a difference. You should probably reinstate these if you are to do development against this build)

GNUmakefile

global_cppflags := -ggdb -fno-exceptions -DBUILDING_CAIRO__ -DBUILDING_GTK__ \
         $(am__append_1) $(am__append_2)
#global_cppflags := -Wall -W -Wcast-align -Wchar-subscripts \
#       -Wreturn-type -Wformat -Wformat-security -Wno-format-y2k \
#       -Wundef -Wmissing-format-attribute -Wpointer-arith \
#       -Wwrite-strings -Wno-unused-parameter -Wno-parentheses \
#       -fno-exceptions -DBUILDING_CAIRO__ -DBUILDING_GTK__ \
#       $(am__append_1) $(am__append_2)
global_cflags := -ggdb
global_cxxflags := -ggdb -fno-rtti

Then to test that debugging symbols were include in the compiler and linker output I ran gdb as follows

~/dev/webkitgtk-2.0.4$ gdb ./Programs/MiniBrowser -d ./Tools/MiniBrowser/gtk/
