Trying to install git on the Unix and Linux machines based on the instructions on Installing Git blog, and it is failing with the below error

make prefix=/u         


        

Answer 1

If you can't access yum, apt-get etc (such as being on a cluster machine with no sudo access), install a new version of openssl locally and manually as follows:

Get the source code, unpack it, enter the directory and make a build directory (very important):

wget https://www.openssl.org/source/openssl-1.0.2r.tar.gz
tar -xvzf openssl-1.0.2r.tar.gz
cd openssl-1.0.2r
mkdir builddir

Configure to your local build destination (make sure its different to your source directory, don't use just /home/yourdir/openssl-1.0.2r/), make and install:

./config --prefix=/home/yourdir/openssl-1.0.2r/builddir --openssldir=/home/yourdir/openssl-1.0.2r/builddir
make
make install

Add the bin and library paths from the build directory to the appropriate variables in your your shell config file (i.e. ~/.bashrc), and source it:

export PATH=/home/yourdir/openssl-1.0.2r/builddir/bin:$PATH
LD_LIBRARY_PATH="/your/other/dirs/libs:/home/yourdir/openssl-1.0.2r/builddir/lib:"
source ~/.bashrc

OpenSSL should now be in your new directory by default:

which openssl
> /home/yourdir/openssl-1.0.2r/builddir/bin/openssl

Now try and reinstall git, perhaps with make distclean.
