Install GCC 4.6 on Fedora 12

Posted onJanuary 10, 2013 by Qin Liu

For some reason, I have to install GCC 4.6 on a Fedora 12 server in the department (sadly that I can’t wipe it out and reinstall a latest version of Ubuntu). I believe the following steps [1] are similar in other versions of Fedora or CentOS. First, install necessary libraries:

sudo yum install gcc mpfr-devel libmpc libmpc-devel glibc-devel

1	sudo yum install gcc mpfr-devel libmpc libmpc-devel glibc-devel

Then download the source code, configure, make and install,

cd ~
mkdir build-gcc
cd build-gcc
wget ftp://ftp.dti.ad.jp/pub/lang/gcc/releases/gcc-4.6.3/gcc-4.6.3.tar.gz # download gcc source
tar xzvf gcc-4.6.3.tar.gz
mkdir build
cd build
../gcc-4.6.3/configure --program-suffix=-4.6 --enable-languages=c,c++
make
sudo make install

cd ~

mkdir build-gcc

cd build-gcc

wget ftp://ftp.dti.ad.jp/pub/lang/gcc/releases/gcc-4.6.3/gcc-4.6.3.tar.gz # download gcc source

tar xzvf gcc-4.6.3.tar.gz

mkdir build

cd build

../gcc-4.6.3/configure --program-suffix=-4.6 --enable-languages=c,c++

make

sudo make install

The GCC will be installed under /usr/local. You can change the install dir by adding –prefix=PATH_TO_INSTALL_DIR on configuration command. To use GCC 4.6 in cmake, set CC=gcc-4.6 and CXX=g++-4.6. You may encounter a fatal error: gnu/stubs-32.h: No such file or directory. [2] This error message shows up on the 64 bit systems where GCC/UPC multilib feature is enabled, and[…]

Random Thoughts on Setup

Posted onJanuary 9, 2013 by Qin Liu

Recently, I love to read the blog The Setup. It includes many interviews about how people get their work done from web developers, kernel developers, professors, researchers, musicians, politics, poet etc. It’s quite interesting and I can learn some new tools and new tricks to help myself in study and work. According to these interviews, most people use MacOS or Linux while the situation in China is quite different that Windows XP is still dominant. After reading one of those interviews, I have give ArchLinux a try in VirtualBox. I think it takes too much time for me to configure a functional system with GUI. Anyway, I’m fine with Ubuntu now. I’ve transferred from Unity to Gnome3 recently. In the[…]
