cc1 and object files vs. static libraries

[Bernhard Beschow]

Hi all,

for my own project I want to use large parts of cc1 compiler's code which is 
part of the latest GCC-4.0.0 that I use. I figured that it would be easiest to 
just use the object files and the static libraries directly.

As the cc1 binary consists of several object files besides some static 
libraries, I put the object files (except main.o) into another static library 
for easier handling. I called this static library libcc1.a.

However, when I try to link the cc1 executable using libcc1.a instead of the 
separate objects, I get linking errors. The linker then complains about 
dublicate definitions and missing symbol references although it should get 
exactly the same objects out of the static libraries as with the normal 
linking procedure. Can somebody please tell me what's going wrong here? And 
what I can do to resolve the linking errors?

Any help is welcome.

Best regards,

Bernhard
