[LLVMdev] Problem Compiling llvm-gcc 4.2

[Kinson Chan 陳傑信]

>>

Dear All,

I have been trying for days but still cannot break this barrier. May I  
get your help?

I have compiled llvm-2.1 successfully and make install. When I proceed  
with llvm-gcc-4.2-2.1, however, I keep getting linking error as  
attached. Some functions with totally different content conflict with  
each other in linking process.

That is a Linux box (Debian, with 2.6.23-1 Kernel) and I have already  
tried combinations of --disable-shared and/or --disable-multilib. It  
get stuck at the same point.

Thanks to Chris, I just realized Java is not supported but have no  
idea how to disable it. I have read the README.LLVM and got no clue.  
(Maybe my English is not good enough - I am not native speaker.)

Once again, thank you all for the great work. Idea of LLVM is really  
attractive to forget about.

Regards,
Kinson
