[LLVMdev] LLVM Build Problems on Itanium

[Thomas Jablin]

Hi,

I am having some difficulties building llvm on Itanium. My procedure for 
building LLVM is:

cd /liberty/llvm.ia64/llvm-2.1
./configure
make ENABLE_OPTIZED=1
cd /liberty/llvm.ia64/obj
/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/configure 
--prefix=/liberty/llvm.ia64/install 
--enable-llvm=/liberty/llvm.ia64/llvm-2.1/ --enable-languages=c,c++ 
--disable-shared

The build of llvm seems to succeed, but llvm-gcc dies with the following 
messages:

gcc -Wall -c -DUSE_LIBUNWIND_EXCEPTIONS -g -fkeep-inline-functions 
-DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes 
-Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros

My system is CentOS 4.5, which includes gcc 3.4.6, flex 2.5.4, m4 1.4.1, 
and bison 1.875c. I have attempted to build llvm-gcc with a self-built 
copies of gcc 4.2.1 and bison 2.3 which yielded similar error messages. 
I have diff'd the Itanium generated copy of gt-dbxout.h against the 
gt-dbxout.h from a successful x86-64 build and found no changes. Any 
help would be greatly appreciated.
