#Ubuntu install gfortran 64 Bit#
It will return a detailed result and somewhere around end, you will see following:įor 64 bit system: =Īttempt to open //usr/local/lib/x86_64-linux-gnu/libgcc_s.so failedĪttempt to open //usr/local/lib/x86_64-linux-gnu/libgcc_s.a failedĪttempt to open //lib/x86_64-linux-gnu/libgcc_s.so failedĪttempt to open //lib/x86_64-linux-gnu/libgcc_s.a failedĪttempt to open //usr/lib/x86_64-linux-gnu/libgcc_s.so failedĪttempt to open //usr/lib/x86_64-linux-gnu/libgcc_s.a failedĪttempt to open //usr/lib/x86_64-linux-gnu64/libgcc_s.so failedĪttempt to open //usr/lib/x86_64-linux-gnu64/libgcc_s.a failedĪttempt to open //usr/local/lib64/libgcc_s.so failedĪttempt to open //usr/local/lib64/libgcc_s.a failedĪttempt to open //lib64/libgcc_s.so failedĪttempt to open //lib64/libgcc_s.a failedĪttempt to open //usr/lib64/libgcc_s.so failedĪttempt to open //usr/lib64/libgcc_s.a failedĪttempt to open //usr/local/lib/libgcc_s.so failedĪttempt to open //usr/local/lib/libgcc_s.a failedĪttempt to open //usr/lib/libgcc_s.so succeededĪttempt to open //usr/local/lib/x86_64-linux-gnu/libgcc_s.so.1 failedĪttempt to open //lib/x86_64-linux-gnu/libgcc_s.so.1 succeeded Now we need to check where the ld is expecting the library. It may return various version for library, we can select the latest one. You will get something similar as following:įor 64 bit system: /usr/lib/gcc/x86_64-linux-gnu/3.4.6/32/libgcc_s.so You can help it, by finding the library yourself: sudo find /usr/ -name libgcc_s.so

This means ld is unable to locate a library ( libgcc_s). g77 hello.f /usr/bin/ld: cannot find -lgcc_s Now again try to compile g77 and you will see that the first two errors are removed and only one is left. bashrc file, make sure, you are not removing anything or redefining anything.
#Ubuntu install gfortran 32 bit#
gedit ~/.bashrcįor 64 bit system: LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATHįor 32 bit system: LIBRARY_PATH=/usr/lib/i386-linux-gnu:$LIBRARY_PATH We need to add this location with “ linux-gnu” and add it to the environmental variable LIBRARY_PATH. This will show results something similar to following.įor 64 bit system: /usr/lib/x86_64-linux-gnu/crti.oįor 32 bit system: /usr/lib/i386-linux-gnu/crti.o We need to find, where is crti.o present in our system to solve this problem? sudo find /usr/ -name "crti.o" usr/bin/ld: cannot find crti.o: No such file or directoryĬollect2: ld returned 1 exit status Solving crti.o error usr/bin/ld: cannot find crt1.o: No such file or directory Nowaday, g77 compilation shows the following errors. Hello World! Solving g77 installation errors You should see a new file named a.out if everything is installed properly and running it will show the output of the Fortran program./a.out Make a simple Fortran program and save as file named hello.f. Now, we need to check whether Fortran 77 compiler is installed properly or not. You need to change the permission of install.sh file to make it excutable. Now, you need to extract the content of this file and run install.sh file present in the extracted folder.

#Ubuntu install gfortran code#
You can use the following command to download it using terminal: wget Installing g77 from source code Downloading g77 Source Codeĭownload g77 compiler source code for linux from following site: In this article, we will install g77 fortran compiler and solve all those issues for Ubuntu 18.04. There may appear some errors during installation due to the incompatiblities of present systems with g77. Since, g77 is not easily found in current repositories, you need to install it using source code for Linux.

For Fortran programming, you can use latest Fortran compilers but compilation of some old packages and softwares may still need g77. The g77 is a GNU Fortran 77 compiler which got replaced by latest Fortran compilers like GFortran.
