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?
