Installation question

Installation question

[Gary Oblock]

A little background. I'm a compiler developer working on
a fairly hairy optimization to run during LTO. After many
months my optimization it's at the point when running
SPEC17 intrate works except for x264_r which dies
during build. On the gcc mailing list Martin Liška looked
at my log and said it seemed to be a "linker" error.
When I provided him with my vendor branch, he got x264_r
to work with my sources. This leads me to believe that
my binutils might be obsolete. I'm using Ubuntu 18.04
with binutils 2.30.

How do I go about installing binutils in my own directory
instead of /usr/local and what do I need to do to get
my compiler under development to use them.

This is my current attempt at an installation script

cd binutils_build
touch build install
rm -rf build install
mkdir build install
cd build
../binutils-2.36/configure
make tooldir=/home/gary/binutils_build/install
make tooldir=/home/gary/binutils_build/install install

Please be detailed with your suggestions because
binutils is something I'm not very familiar with.

Thanks,

Gary Oblock

$ tar Jxf binutils-2.36.1.tar.xz
$ cd binutils-2.36.1
$ ./configure --prefix=<dir>
$ make
$ make install

If you *only* want to install the linker, run the following instead of
"make install":
  $ make -C ld install

If you want things to go as smoothly as possible, configure both gcc
and binutils with exactly the same --prefix specifying the root of
their installation tree.  Always configure from the top of the source
tree, ie. don't run ld/configure or gas/configure etc.  You may avoid
building gdb with --disable-gdb --disable-gdbserver --disable-sim
--disable-readline --disable-libdecnumber if using binutils-gdb git
sources.

Posting this sort of legal nonsense to a public mailing list isn't
clever.  To put it bluntly, it is the email etiquette equivalent of
going into a public square and shouting "Do not listen to me"!  With
an unsaid "I am an idiot".  Some people will follow the instructions
and immediately delete such a message, resulting in your emails being
unanswered.

My current gcc build is this:

cd $1
BASE=`pwd`
echo BASE = $BASE
touch objdir install
rm -rf objdir install
mkdir objdir install
cd objdir
echo BUILDING IN `pwd`
../sources/configure --prefix=$BASE/install --disable-bootstrap -enable-language=c,c++,lto --disable-multilib --enable-valgrind-annotations
make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' -j 12
make install

So change it to be??

cd $1
BASE=`pwd`
echo BASE = $BASE
touch gcc_objdir binutils_objdir install
rm -rf *_objdir install
mkdir gcc_objdir binutils_objdir install
cd gcc_objdir
echo BUILDING GCC IN `pwd`
../gcc_sources/configure --prefix=$BASE/install --disable-bootstrap -enable-language=c,c++,lto --disable-multilib --enable-valgrind-annotations
make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' -j 12
make install
cd ../binutils_ojbdir
echo BUILDING BINUTILS IN `pwd`
../gcc_sources/configure --prefix=$BASE/install
make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' -j 12
make install

It's late at night here and I'll try this tomorrow if I don't
see flaming arrows raining down at me. 😉

Thanks,

Gary

It is better to build and install binutils first, so that the gcc
configure sees an up-to-date assembler and linker.  New gcc features
might not be enabled otherwise.

Re: Installation question

Alan,

Actually, building gcc second seems to result in gcc cleaning out
the binutils content from the install directory!

Does anybody out there know how I'd go about debugging the
linker myself? I ask this because the one who tried to help
can't seem to duplicate the problem on their machine...

Sounds like something silly you did in a script.  I have installed
binutils and gcc myself countless times without seeing anything like
this.  So have many other people.
