Compile and install GCC5.3.0 in Linux

Compile and install GCC5.3.0 in Linux

System Environment: Amazon Linux AMI 2015.09.2 (HVM) --- Fedora 23 Server

1. Download The gcc-5.3.0installation package and put gcc-5.3.0.tar.gz in the/opt directory for decompression:

# Sudo su

# Mkdir/opt/& cd/opt/

# Wget http://ftp.gnu.org/gnu/gcc/gcc-5.3.0/gcc-5.3.0.tar.gz

# Tar-zxf gcc-5.3.0.tar.gz

2. Create the installation directory:

# Mkdir/usr/local/The gcc-5.3.0/

# Cd/usr/local/gcc-5.3.0/

3. Configure the installation file:

#/Opt/gcc-5.3.0/configure-prefix =/usr/local/gcc-5.3.0

If the following error occurs during execution:

-----------------------------------------------------------------------

Configure: error: in '/usr/local/gcc-5.3.0 ':
Configure: error: no acceptable C compiler found in $ PATH

See 'config. log' for more details.

-----------------------------------------------------------------------

The C compiler is not found in $ PATH.
If the system has a gcc compiler, set the environment variable.
For example:
Export PATH = $ PATH:/usr/local/bin

If not, install the rpm package of lower gcc versions first.

Installation sequence: cpp-kernel ---> headers ---> glibc ---> devel ---> libgomp ---> gcc

Repeat Step 3 and an error occurs:

Bytes -------------------------------------------------------------------------------------------------
Configure: error: Building GCC requires GMP 4.2 +, MPFR 2.3.1 + and MCM 0.8.0 +.
Try the -- with-gmp, -- with-mpfr and/or -- with-mpc options to specify
Their locations.
Bytes -------------------------------------------------------------------------------------------------

Error Description: To install gcc, you need to install the GMP, MPFR, and MPC libraries. You can download the corresponding compressed packages from ftp://gcc.gnu.org/pub/gcc/infrastructure. Since MPFR depends on GMP, while nmms depends on GMP and MPFR, it is necessary to install GMP first, followed by MPFR, and finally the nmms.

①. Install gmp4.3.2

# Tar jxvf gmp-4.3.2.tar.bz2

# Mkdir/usr/local/gmp-4.3.2

# Cd/usr/local/gmp-4.3.2

#/Opt/gmp-4.3.2/configure-prefix =/usr/local/gmp-4.3.2

# Make

Make install

② Install mpfr2.4.2

# Tar jxvf mpfr-2.4.2.tar.bz2

# Mkdir/usr/local/mpfr-2.4.2

# Cd/usr/local/mpfr-2.4.2

#/Opt/mpfr-2.4.2/configure -- prefix =/usr/local/mpfr-2.4.2 -- with-gmp =/usr/local/gmp-4.3.2
# Make

# Make install

③ Install mpc0.8.1

# Tar-zxf mpc-0.8.1.tar.gz

# Mkdir/usr/local/mpc-0.8.1

# Cd/usr/local/mpc-0.8.1

#/Opt/mpc-0.8.1/configure -- prefix =/usr/local/mpc-0.8.1 -- with-gmp =/usr/local/gmp-4.3.2 -- with-mpfr =/usr/local/mpfr-2.4.2

# Make

# Make install

④ Re-install GCC configuration and installation options

# Cd/usr/local/gcc-5.3.0

#/Opt/gcc-5.3.0/configure -- prefix =/usr/local/gcc-5.3.0-enable-threads = posix-disable-checking-disable-multilib-enable-versions ages = c, c ++ -- with-gmp =/usr/local/gmp-4.3.2 -- with-mpfr =/usr/local/mpfr-2.4.2 -- with-mpc =/usr/local/mpc-0.8.1

4. Compile the Installation File

# Make

Again:

/Usr/local/gcc-5.3.0/./prev-gcc/cc1plus: error while loading shared libraries: libmp C. so.2: cannot open shared object file: No such file or directory
Make [3]: *** [real. o] Error 1

Make: *** [all] Error 2
Analysis:/usr/local/gcc-5.3.0/x86_64-unknown-linux-gnu/libgcc/config. log

When an error is found, many errors are found, most of which are not found in the database.

# Export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib

# Make

About 30 minutes later ···
Finally, the compilation is successful.

Libtool: link: ranlib. libs/libatomic.
Libtool: link: (cd ". libs" & rm-f "libatomic. la" & ln-s "../libatomic. la" "libatomic. la ")
True DO = all multi-do # make
Make [4]: Leaving directory '/usr/local/gcc-5.3.0/x86_64-unknown-linux-gnu/libatomic'
Make [3]: Leaving directory '/usr/local/gcc-5.3.0/x86_64-unknown-linux-gnu/libatomic'
Make [2]: Leaving directory '/usr/local/gcc-5.3.0/x86_64-unknown-linux-gnu/libatomic'
Make [1]: Leaving directory '/usr/local/gcc-5.3.0'

5. Install gcc:

# Make install

6. Add the new version of gcc to the command search path:

# Ln-s/usr/local/The gcc-5.3.0/bin/gcc
# Ln-s/usr/local/gcc-5.3.0/bin/g ++

7. Add environment variables:

# Vi/etc/bashrc

Add code:

Add the following code:

# Gcc
LD_LIBRARY_PATH =:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib:/usr/local/gcc-4.6.1/lib

# Export LD_LIBRARY_PATH

This installation is complete!
