Consider two common user: A & B, neither has sudo privilage.

/home/A  A  A  rwx------
/home/B  B  B  rwx------

A wanted to build git from source code:

cd /home/A/third-src
wget & extract git.source
./configure --prefix=/home/A/third/git
make install  # install without root
export PATH & LD_LIBRARY_PATH
# Here A can use git correctly

Now B wanted to reuse A's git, so B asked root to

cp -r /home/A/third/git /home/B/third/git
chown -R B:B /home/B/third/git

B exported PATH & LD_LIBRARY_PATH for B's git, and expected to use git correctly, but it does not work!! git complains no permission to read file in /home/A/third/git:

git init
fatal: unable to access '/home/A/third/git/etc/gitconfig': Permission denied

It seems --prefix put absolute path into executable files. 

strings bin/git  # it really lists /home/A/third/git

How to fix it? Is there a canonical way to share locally installed program to others without using root?

Thank you in advance.

There is issue with your permission which includes user, group etc. Here is some reason for git behaviour:

  1. Git reads config settings from a variety of paths and the <USER> doesn't have access to some of them.

  2. Git tries to read root config setting instead of config settings due to the starting script using su command with do not reset environment variables option (-m):

    /bin/su -m $USER -c "cd $BASE/logs && $BASE/bin/startup.sh &> /dev/null"

You can try few thing to fix:

  1. Fix the permission:

    chown <USER>.<GROUP> -R /home/<USER>/.config

    chown <USER>.<GROUP> -R /home/<USER>/.gitconfig

  2. Recompile using default options:

The second part of your answer that how can two user share locally installed program ?

There few ways I can think of right now is:

  1. Add user B to user A Access Control List(ACL) list using setfacl command.
  2. Create a separate group with proper permission setting etc. and add A and B both in that group.
  3. Install the program in that common space which both can use. Like non-standard path which may include a directory which has access to both or a separate partition which has access to every one depending to your needs.
