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 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.

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:
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 <relst@relst.nl>' --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 <relst@relst.nl>' --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.
