Installing GCC 3.0 on Redhat

Installing GCC 3.0 on Redhat

[Premetz, Dan (MED)]

OK.  I purchased the "Using and Porting GNU CC" from the Free Software 
Foundation.  I thought I knew what I was doing from reading the book, 
until I actually tried to implement what I'd read.

I run the "configure" script for GCC 3.0.  This does a slew of "checks".

All OK.  I am in the "gcc-3.0" directory when I type "make LANGUAGES=c".

The make compiles for a couple of minutes, then runs a bunch of "link" 
commands, then another bunch of "checks".

Problem: During the "check" phase of the "stage 1" compilation, I get
the 
following error...

"checking for g++ that will successfully compile libstdc++-v3... 
configure: error: please upgrade to GCC 3.0 or above
make: *** [configure-target-libstdc++-v3] Error 1"

I thought the "LANGUAGES=c" argument on the make line would only build
the C compiler stuff.  Why does it care about the C++ stuff during the
stage 1 compilation?

I'm stuck.  Please help.

Hi Dan,

You shouldn't build or configure from the gcc-3.0 directory. The docs
complain against this.
in Your src directory unpack the distro and create a build directory, that
it looks like this:
/usr/src # ls
gcc-3.0    build
/usr/src #
for instance
Change to the build directory and do a:
/usr/src/build # ../gcc-3.0/configure ... --enable-languages=c,c++ ...
...
/usr/src/build # make bootstrap
/usr/src/build # make install
This all can be found in the /usr/src/gcc-3.0/{README,INSTALL} files and
should solve
Your problems.

Hope this helps
Frank

It doesn't.  It got past `stage 1' and started building target
libraries.  The C++ language had been enabled at configure time, so
the top-level make attempted to configure and build the target library
after building the compiler.

LANGUAGES="lang lang lang..." is deprecated.  Use
--enable-languages=lang,lang,lang... at configure time instead.

help on cross-compile applications

[Ming Ouyang]

Hi,
I installed gcc 3.0 for mips and newlib 1.9.0 on my
redhat box, and I have compiled linux kernel 2.4.3 for
mips successfully, but when I tried to compile some
simple applications, I always got error messages like
"can't find xxx.h", does that means newlib is not
enough and I should install glibc or something else?
If I need glibc, which version is the best?
Thanks for any help so much.

Ming

Newlib is for applications which do not use an OS.  

You need to build a bootstrap version of gcc, build glibc with
the bootstrap-gcc, then build a final version of gcc.  You also
need the kernel headers from linux to build glibc.  Use the glibc-2.2.3.
Read the CrossGCC FAQ.
