Gcc 5.3.0

drrahul · 04-18-2017, 05:58 AM

I want to install GCC 5.3.0 in my workstation(centOS 6.9)

When i try installing I am getting the following error

configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[2]: *** [configure-stage1-target-libgcc] Error 1
make[2]: Leaving directory `/root/gcc-5.3.0'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/root/gcc-5.3.0'
make: *** [all] Error 2

I have installed latest versions of mpc mpfr and GMP.

Can you help me solve this problem?

GCC requires a build folder outside gcc-5.3.0/ .

If you configured inside gcc-5.3.0/, please delete gcc-5.3.0/, and start from scratch.

Unpack mpfr-3.1.3.tar.xz, gmp-6.1.0.tar.xz, mpc-1.0.3.tar.gz into gcc-5.3.0/.
Rename to have gcc-5.3.0/{ mpfr/, gmp/, mpc/ }.

Code:

mkdir build-gcc
cd build-gcc/
../gcc-5.3.0/configure --prefix=/usr/local/gcc53 --program-suffix=53 --enable-languages=c,c++ --with-system-zlib --disable-multilib

[QUOTE=knudfl;5698481]GCC requires a build folder outside gcc-5.3.0/ [QUOTE]

>yup now gmp, mpfr, mpc are in path /opt/src
>gcc5.3.0 is placed in the same path and follwing commands are executed

mkdir /opt/gcc-5.3.00(renamed as there is already a folder named gcc-5.3.0)
mkdir objdir
cd objdir
../gcc-5.3.0/configure --prefix=/opt/gcc-5.3.0 --enable-languages=c,c++ --with-gmp=/opt/gmp-6.1.0 --with-mpfr=/opt/mpfr-3.1.4 --with-mpc=/opt/mpc-1.0.3 --disable-multilib

Now I get the following error

configure: error: building out of tree but ../gcc-5.3.0 contains host-x86_64-unknown-linux-gnu.
Use a pristine source tree when building in a separate tree

Re #2.

More information : gcc-5.3.x can be built with => gcc-4.7. I used gcc-4.9.3.

Same procedure with mpfr, gmp, mpc , etc.
../gcc-4.9.3/configure --prefix=/usr/local/gcc493 --program-suffix=49 --enable-languages=c,c++ --disable-libstdcxx-pch --disable-multilib --with-system-zlib

I am using gcc 4.7 and still getting too many errors.

I have make a note on the error in my previous mail. Do you find it.? What about a solution for it?

Re #3.

Why not follow the tested procedure, with { mpfr/, gmp/, mpc/ } inside gcc-5.3.0/ ?
I.e. gcc-5.3.0/{ mpfr/, gmp/, mpc/ }

Quote:

but ../gcc-5.3.0 contains host-x86_64-unknown-linux-gnu

Looks like a wrecked gcc-5.3.0/ . Suggest : Delete gcc-5.3.0/ and ...
tar xvf gcc-5.3.0.tar.bz2

Re #5.

You are not supposed to get any errors at all when doing as post #2.

And : Which gcc-4.7 are you using ? The devtools-?-gcc won't do !

I am following these commands. Can you please go through it?

This looks like you are running 'make' inside gcc-5.3.0/ ?

Remember that you can't simply "start over in another directory" having attempted the job in the wrong place. You have already messed it up and must perhaps make distclean.

Re #8 , https://yhigu.wordpress.com/2016/03/...m-source-code/

As complicated as possible is usually wrong. Doesn't look like an experienced gcc builder.
And the links will overwrite the system files. ( /usr/bin/gcc, g++ ). Bad idea.
Don't do. Use a '--program-suffix'.

When compiling a program with gcc-5.3, use the compilers with, examples :
1. export CC=gcc53 CXX=g++53 && ./configure && make
2. (cmake) : CC=gcc53 CXX=g++53 cmake ..

Can you kindly give me the entire commands to install this package?

GCC 5.3

or is it good to get your mail id?

Re #14.

The procedure is post #2.
When the configuring has been done : make && make install
The important thing is also : Use a valid => gcc-4.7, e.g. gcc-4.9.3

And :
cd /usr/bin/
ln -s /usr/local/gcc53/bin/gcc53
ln -s /usr/local/gcc53/bin/g++53
