Title       : 	Statically (cross) compiled vim for x86, x86-64 and mipsel

Sometimes I need to manage a few systems with either low resources or a very
restricted set of packages. On those systems no compilers or development
libraries are available, however it is allowed to bring binaries.
A few of those systems are 32 bit x68 systems, some are MIPS systems, even
worse. They serve a secure purpose, I cannot go in to much detail about them,
except for they require a high level of security, they process certificates.
I really like vim as my editor, the only editor available by default on those
systems is `ed`. I have an [ed cheatsheet][1] for this purpose.
The solution for this problem is to create a statically (cross) compiled version
of `vim`.
These instructions are for Debian/Ubuntu, tested on an Ubuntu 14.04 64 bit
machine.

I'm developing an open source monitoring app called Leaf Node Monitoring, for windows, linux & android. Go check it out!

### Install required packages
First install the required development libraries and git:
    
    
    apt-get install libncurses5-dev git build-essential
    
If you need to cross compile from 64 bit to 32 bit, also install
`libc6-dev-i386`:
    
    
    apt-get install libc6-dev-i386
    
The MIPS hardware has a special toolchain which have specific instructions not
covered here. The manufacturer probably covers this in their documentation.
### Vim source code
Clone the vim source from [github][3]:
    
    
    git clone https://github.com/b4winckler/vim.git
    
Go to the `vim/src` folder:
    
    
    cd vim/src/
    
### Compile time
Set the compile flags for vim and start the compile:
    
    
    export LDFLAGS="-static"
    export MAKEFLAGS="-j4"
    export CFLAGS=""
    ./configure --with-features=small  --with-compiledby='Remy '  --with-x=no  --disable-gui  --disable-netbeans  --disable-pythoninterp  --disable-python3interp  --disable-rubyinterp  --disable-luainterp 
    
The above `LDFLAGS` make sure Vim gets statically compiled. The other options
disable any GUI support (x) and enable a portion of the features, namely the
`small` featureset. This lacks syntax highlighting and such. See below for a vim
`:version` output.
If you need to compile on a 64 bit machine for a 32 bit machine, export the
following `CFLAGS`:
    
    
    export CFLAGS="-m32"
    
To compile for `mips`:
    
    
    ./configure --with-features=small  --with-compiledby='Remy '  --with-x=no  --disable-gui  --disable-netbeans  --disable-pythoninterp  --disable-python3interp  --disable-rubyinterp  --disable-luainterp --target=mipsel-safenet # or mipsel-linux
    
Start the actual compile:
    
    
    make
    
### Results
When it is finished you should have a fairly small `vim` file:
    
    
    $ ls -la vim
    -rwxr-xr-x 1 remy remy 1.4M Sep 17 04:06 vim
    
Check that it is statically linked:
    
    
    $ ldd vim
        not a dynamic executable
    
A non-statically compiled vim gives me this:
    
    
    $ ldd /usr/bin/vim
            linux-gate.so.1 =>  (0xb77c7000)
            libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb7799000)
            libtinfo.so.5 => /lib/i386-linux-gnu/libtinfo.so.5 (0xb7779000)
            libselinux.so.1 => /lib/i386-linux-gnu/libselinux.so.1 (0xb7758000)
            libacl.so.1 => /lib/i386-linux-gnu/libacl.so.1 (0xb774e000)
            libgpm.so.2 => /usr/lib/i386-linux-gnu/libgpm.so.2 (0xb7748000)
            libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb75fa000)
            libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb75f6000)
            /lib/ld-linux.so.2 (0xb77c8000)
            libattr.so.1 => /lib/i386-linux-gnu/libattr.so.1 (0xb75ef000)
    
You can also use the `file` command:
    
    
    $ file vim
    vim: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.26, BuildID[sha1]=0x97cb04dde25cd539487369524b0787fd422044be, not stripped
    
You can decease the filesize with 0.1 MB by stripping:
    
    
    $ strip vim
    $ ls -la vim
    -rwxr-xr-x 1 remy remy 1.3M Sep 17 04:04 vim
    
The same `vim`, dynamically compiled (without the `LDFLAGS="-static"`), is a
little bit smaller:
    
    
    $ ls -la vim
    -rwxr-xr-x 1 remy remy 793K Sep 17 04:17 vim
    
That's it. You can copy/`scp` the `vim` file anywhere and use it, as long as it
is the correct architecture. Even on restricted systems in my case.
These instructions work for almost all programs you can compile. The
`LDFLAGS="-static"` is the magic part here. You can try it for yourself with
other software.
### Version info
Here is the output of the `:version` in `vim` itself:
