There's a special environment variable (LD_MATH) to tell the build procedure where the math library is on systems that need such help. Please try the following: 1. Go to the top-level source-directory. 2. Perform steps 3 through 5 described near the end of the file INSTALL. 3. Set the environment variable LD_MATH to reference the math library: export LD_MATH='-L/usr/lib/libm.a -lm' 4. Perform steps 6 through 9 described near the end of the file INSTALL. Please let me know if this helps. > I really appreciate you help. > Best regards, > > Marcelo Regards, Steve Emmerson
