Hi,
I am building
glibc 2.5.1. My goal is to have the math library
/lib/libm-2.5.1.so to performance math operations with the SSE/SSE modules instead of the default 387 FPU, for the reason for numerical quality.
This is how I configure
glibc.
Code:
$ ../glibc-2.5.1/configure CFLAGS="-mfpmath=sse -msse -msse2" CXXFLAGS="-mfpmath=sse -msse -msse2" --prefix=/usr
The configure process finished successfully with 0 as the exit code. Then, I make'ed glibc with the following command line.
Then, I got the following errors (only the last couple lines are shown but it contains all error messages).
Code:
rm -f /home/ykwok2/tmp/glibc/src/object-2.5.1/csu/abi-tag.h.new
make[2]: *** [/home/ykwok2/tmp/glibc/src/object-2.5.1/tcb-offsets.h] Error 1

Do you have a clue? Please help. Thank you!
