The bug is on the GCC 4.8 side, so either you need to patch it, or build with -std=gnu++98 - then __GNUC_STDC_INLINE__ will not be defined and it ought to compile fine.

Answer from Artem S. Tashkinov on Stack Exchangeit worked with the following:
../gcc-4.8.5/configure CC="/opt/gcc4.5/bin/gcc" --prefix=/opt/gcc4.8.5 --enable-languages=c,c++,fortran --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object
The interesting part is CC=...
The installed gcc-version is 4.4. With this version, the compiling fails.
kind regards
GCC is documented to need to be built outside of its source tree; see the configuring chapter of its installation documentation:
First, we highly recommend that GCC be built into a separate directory from the sources which does not reside within the source tree. This is how we generally build GCC; building where
srcdir == objdirshould still work, but doesn’t get extensive testing; building where objdir is a subdirectory of srcdir is unsupported.
So you need to build it according to that rule. Hence your GCC build:
cd gcc-4.8.5
#wrong code from the original question! Don't use that
./configure --enable-bootstrap --enable-shared \
--enable-threads=posix --enable-checking=release \
--with-system-zlib --enable-__cxa_atexit \
--disable-libunwind-exceptions --enable-gnu-unique-object \
--enable-languages=fortran,c --prefix=/opt/gcc4.8.5
is wrong; I would recommend at least:
cd gcc-4.8.5
mkdir ../_BuildGCC
cd ../_BuildGCC
../gcc-4.8.5/configure --enable-bootstrap --enable-shared \
--enable-threads=posix --enable-checking=release \
--with-system-zlib --enable-__cxa_atexit \
--disable-libunwind-exceptions --enable-gnu-unique-object \
--enable-languages=fortran,c --prefix=/opt/gnu \
--program-suffix=-mine
then, after the entire build, probably with
make -j4
followed by some mkdir /opt/gnu with appropriate user and permission, then (in the same _BuildGCC)
make install DESTDIR=/tmp/gccinst
and finally cp -vr /tmp/gccinst/opt/gnu /opt/gnu to be run appropriately (perhaps as root...., and perhaps cp -va)
Then you would add /opt/gnu/bin/ to your PATH variable, and you would use gcc-mine to compile your code.
BTW, GCC is compatible for C programs since the ABI don't change. And GCC 4.8 is obsolete and unsupported. You'll better compile from source the supported versions (listed on gcc.gnu.org; in January 2018, GCC 7.2 & GCC 6.4)
Perhaps your particular Redhat system requires additional/specific CFLAGS to be appended into your configure command. You could ask your Redhat support, or try to append CFLAGS=-fPIE or CFLAGS=-fPIC at the end of your ../gcc-4.8.5/configure command.
At last, you might perhaps get such help on [email protected], but you'll better try with a recent GCC. Few GCC folks remember 4.8 ....
If you really need precisely GCC 4.8 (but I doubt that), you could buy costly support (e.g. from RedHat or AdaCore folks) if needed.
With Google I found Installing gcc 4.8 and Linuxbrew on CentOS 6
Is GCC-4.8 available for 12.04 Precise now?
Update: As of 6/05/2013, there is currently a release of gcc 4.8.1 for 12.04(precise) available at https://launchpad.net/~ubuntu-toolchain-r/+archive/test.
The short answer is: gcc-4.8 is currently available for 12.04(Precise) via the toolchain PPA or by compiling the source(see below for details).
Release Announcement
The announcement for the release of gcc-4.8 was made on March 22nd, so you probably won't be seeing this in an official repository just yet.
However, it appears that Launchpad does have a PPA available for the toolchain test builds that does include gcc-4.8, here: https://launchpad.net/~ubuntu-toolchain-r/+archive/test
According to the changelog and package list, there are debs for i386, amd64, arm, and powerpc and were built against raring 13.04.
The latest available version of gcc, for 12.04, is 4.8.1 and is available in the toolchain PPA.
Adding the toolchain/test PPA:
To add the PPA to your system, open a terminal(Ctrl+Alt+t) and run the following commands:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
You will also be prompted to install a number of suggested packages. These packages are recommended, but optional, for the installation of gcc-4.8.
- What are PPAs and how do I use them?
- Are PPA's safe to add to my system and what are some "red flags" to watch out for?
What C++ features are available in gcc-4.8 that are not available in gcc-4.7.2?
- According to GNU.ORG, gcc-4.7, supports a number of C++11 features.
As of the gcc-4.8 release, gcc-4.7 does not support 8 out of 64 features (See C++0x/C++11 Support in GCC)
These features are:
Language Features - Rvalue references for *this - Generalized attributes - Alignment support - Inheriting constructors Concurreny - Bidirectional Fences - Memory model - Abandoning a process and at_quick_exit - Thread-local storage- For a full list of changes in gcc-4.8, see the Changelist
I need these gcc features on 12.04 Precise, now. How can I get them?
Building GCC-4.8 from source:
If you need gcc-4.8 on 12.04 now, your only option is to build it from source.
Please read the GCC installation FAQ prior to installation.
You can download gcc-4.8 from one of gnu.org's mirror sites or directly from their SVN server.
Here is an example of steps to compile from source (see here for additional details.) Note that these may vary depending on your system and preferences.
Download the source code
- Make a build directory (
mkdir gcc-build && cd gcc-build) - Download the source file:
wget http://www.netgull.com/gcc/releases/gcc-4.8.0/gcc-4.8.0.tar.bz2(adjust this command to use an appropriate mirror site. - Unzip the file (
tar -xvjf <file name>)
- Make a build directory (
Install some additional libraries (
sudo apt-get install libgmp-dev libmpfr-dev libmpc-dev libc6-dev)- Compile the source:
./gcc-4.8.0/configure --prefix=/app/gcc/4.8.0 - Run
make(This will take some time to complete. Go make some coffee, or bake some cookies. ;-)) - Install the code:
sudo make install
Once this process has completed, run the command gcc --version to verify that the installation has completed successfully. You should see something similar to the following output:
maggotbrain@foucault:~$ gcc --version
gcc (Linaro 4.8.0) 4.8.0
Copyright (C) 2013 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
The bottom line: Thank all those folks who provide easy to install Ubuntu backports for you. Give them some of the cookies that you baked while running make. ;-)
So answer above works, at least for manual install. Though even after sudo make install, running gcc still just runs the stock version 4.6.3. Even trying gcc-4.8 or gcc-4.8.0 doesn't work. Running /app/gcc/4.8.0/bin/gcc appears to be the only thing that works for me. I mean it is kind of lame but at least it works.
