Well, I found that I should add libmpfr to the LD_LIBRARY_PATH... After that, it successfully build until falling into a infinite loop (seems to be, an hour there...still cannot finish): /home/wuxi/bosh/build/compiler/./prev-gcc/xgcc -B/home/wuxi/bosh/build/compiler/./prev-gcc/ -B/home/wuxi/bosh/install/compiler/ia64-unknown-linux-gnu/bin/ -c -DUSE_LIBUNWIND_EXCEPTIONS -g -O2 -DIN_GCC-W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wc++-compat -fno-common -DHAVE_CONFIG_H -I. -Icp -I../../../src/compiler/gcc -I../../../src/compiler/gcc/cp -I../../../src/compiler/gcc/../include -I../../../src/compiler/gcc/../libcpp/include -I/usr/local//include -I/usr/local//include -I../../../src/compiler/gcc/../libdecnumber -I../../.. /src/compiler/gcc/../libdecnumber/dpd -I../libdecnumber ../../../src/compiler/gcc/cp/typeck.c -o cp/typeck.o This time I have no idea...
