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 -Wold-style-definition -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -I. -I. -I/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc -I/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/. -I/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/../include -I/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/../libcpp/include -I/liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/../libdecnumber -I../libdecnumber -I/liberty/llvm.ia64/llvm-2.1/include -I/liberty/llvm.ia64/llvm-2.1//include -DENABLE_LLVM -I/liberty/llvm.ia64/llvm-2.1/include -D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS /liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/dbxout.c -o dbxout.o In file included from /liberty/llvm.ia64/llvm-gcc4.2-2.1.source/gcc/dbxout.c:4365: ./gt-dbxout.h: In function ‘gt_ggc_ma_type_queue’: ./gt-dbxout.h:83: error: ‘type_queue’ undeclared (first use in this function) ./gt-dbxout.h:83: error: (Each undeclared identifier is reported only once ./gt-dbxout.h:83: error: for each function it appears in.) ./gt-dbxout.h:85: error: ‘type_queue_index’ undeclared (first use in this function) ./gt-dbxout.h: In function ‘gt_pch_pa_type_queue’: ./gt-dbxout.h:99: error: ‘type_queue’ undeclared (first use in this function) ./gt-dbxout.h:101: error: ‘type_queue_index’ undeclared (first use in this function) ./gt-dbxout.h: In function ‘gt_pch_na_type_queue’: ./gt-dbxout.h:114: error: ‘type_queue’ undeclared (first use in this function) ./gt-dbxout.h:116: error: ‘type_queue_index’ undeclared (first use in this function) ./gt-dbxout.h: At top level: ./gt-dbxout.h:205: error: ‘type_queue’ undeclared here (not in a function) ./gt-dbxout.h:250: error: ‘type_queue_size’ undeclared here (not in a function) ./gt-dbxout.h:250: error: initializer element is not constant ./gt-dbxout.h:250: error: (near initialization for ‘gt_pch_rs_gt_dbxout_h[0].base’) ./gt-dbxout.h:250: error: initializer element is not constant ./gt-dbxout.h:250: error: (near initialization for ‘gt_pch_rs_gt_dbxout_h[0].stride’) ./gt-dbxout.h:251: error: ‘type_queue_index’ undeclared here (not in a function) ./gt-dbxout.h:251: error: initializer element is not constant ./gt-dbxout.h:251: error: (near initialization for ‘gt_pch_rs_gt_dbxout_h[1].base’) ./gt-dbxout.h:251: error: initializer element is not constant ./gt-dbxout.h:251: error: (near initialization for ‘gt_pch_rs_gt_dbxout_h[1].stride’) make[3]: *** [dbxout.o] Error 1 make[2]: *** [all-stage1-gcc] Error 2 make[1]: *** [stage1-bubble] Error 2 make: *** [all] Error 2 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. Tom
