This is my first build of gcc. I downloaded gcc 4.1.1 onto a RedHat 8 Linux system on Intel Pentium 4 with its gcc 3.2. I have srcdir = /misc/gcc-4.1.1/ objdir = /FPCETS/gcc4.1.1/ I did cd objdir srcdir/configure --prefix=/FPCETS/gcc411 --enable-languages=c,c++ make bootstrap make install A compiler is built and mostly works. However, <tgmath.h> is not usable. In doing some research, I do NOT find a <tgmath.h> in the 4.1.1 tree, but do find one in the 3.2 tree. I assume that mixing a 4.1.1 compiler with a 3.2 header is a problem. So, how do I build gcc 4.1.1 and force it to create all the C headers in the 4.1.1 tree? Also, I am writing tests of Decimal Floating-Point (DFP), but have not found out how to have the compiler recognize _Decimal64 and the other DFP types. I assume that I am either building the compiler wrong, or invoking the compiler wrong. Any suggestions on how to make DFP usable? --- Fred J.
