If you are a Fortran programmer, you can use some of the Fortran 2008 features like do concurrent with gfortran-10.1: 1 integer, parameter :: mm = 100000 2 real :: a ( mm ), b ( mm ) 3 real :: fact = 0.5 4 5 ! initialize the arrays 6 !. You can compile the above code if you pass std=c++17 to the compiler and you should get a compiler error triggered by lines 14 and 20 from the above code 1 g++-10.1 -std=c++17 -Wall -pedantic test_assert.cpp -o test_assert 2 test_assert.cpp: In instantiation of ‘void print(const T&) ’: 3 test_assert.cpp:24:13: required from here 4 test_assert.cpp:14:33: error: static assertion failed 5 14 | static_assert(std::is_pod::value) 6 | ^~~~~ Open your favorite text editor and copy the next piece of code (I assume you’ll save the file as test_lambda.cpp): 1 // C++14 generalized lambda (could use "auto" for the type of a parameter) 2 #include 3 4 int main () bashrc (this is automatically done when you restart your machine): 1. Now, you just need to instruct Bash to reload. bashrc the above export lines, save the file and close gedit. bashrc ? No problem, you can find it from your Terminal: 1 cd ~ 2 gedit.

bashrc file: 1 export export PATH=/usr/local/gcc-10.1.0/bin:$PATH 2 export LD_LIBRARY_PATH=/usr/local/gcc-10.1.0/lib64:$LD_LIBRARY_PATHĭon’t know how to open. If you want to permanently add the compilers to your system’s path, add the next two lines at the end of your.

Once the above phase is finished, you can install the built GCC with: 1 sudo make install-strip I have a quad-core system, so I will use 8 parallel jobs to build GCC: 1 make -j 8ĭepending on the speed of your computer the build phase could take from about 30 minutes to a few hours. Now, we are ready to build GCC, you typically want to pass twice the number of your computer cores to the make command in order to speed up the build. You typically don’t want to mess the system’s default GCC because other packages may depend on the default version. In order to keep the system clean, we will use /usr/local/gcc-10.1.0 for the installation folder and append the suffix -10.1 to the GCC compilers.
Next, we’ll download the GCC 10 source and his prerequisites from : 1 cd ~ 2 wget 3 tar xf gcc-10.1.0.tar.xz 4 cd gcc-10.1.0 5 contrib/download_prerequisitesĪt this point, we can configure the build. Now, install the default GCC toolchain and a few extra utilities with: 1 sudo apt install build-essential wget m4 flex bison

GCC 10 has C11 and C++14 support enabled by default, no need to add -std=c11 or -std=c++14.įirst, let’s make sure that we have an up to date system: 1 sudo apt update 2 sudo apt upgrade The default version of GCC on Ubuntu 20.04 is 9.3 which is not bad, however version 10 has complete C++11, C++14, C++17 support and partial C++20 support. This is a short article about compiling GCC 10.1 from sources on Ubuntu 20.04 64 bits.
