How can I share a PATH?

  • 772

I used the following commands to install g77 compiler on Ubuntu 19.04: 

sudo gedit /etc/apt/sources.list

Then to the bottom of that file I added:

deb [trusted=yes] old-releases.ubuntu.com/ubuntu hardy universe   
deb-src [trusted=yes] old-releases.ubuntu.com/ubuntu hardy universe 
deb [trusted=yes] old-releases.ubuntu.com/ubuntu hardy-updates universe 
deb-src [trusted=yes] old-releases.ubuntu.com/ubuntu hardy-updates universe

Then: 

sudo apt update
sudo apt install g77

I also tried: 

sudo apt update 
sudo apt install fort77 gfortran

When using 'make' command to install the HypoDD double-difference earthquake hypocenter location program, these lines appear:

/usr/bin/ld: cannot find crt1.o: No such file or directory 
/usr/bin/ld: cannot find crti.o: No such file or directory

When using this command:

find /usr/ -name crti*

I found these files existed in the following path:

/usr/libx32/crti.o
/usr/mipsel-linux-gnu/lib/crti.o
/usr/lib32/crti.o
/usr/lib/x86_64-linux-gnu/crti.o

How can I solve this problem to run the 'make' command?

paths make fortran 19.04

    I solved the problem using the instructions in: http://seanelvidge.com/2017/01/install-g77-on-ubuntu-14-04/ as follows:

    sudo find /usr/ -name "crti.o"
gedit ~/.bashrc

    then adding to the end of the file

    LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH
export LIBRARY_PATH

    save and close then 

    source ~/.bashrc
