Creating an extension for TinyCore Linux is fairly straightforward thanks to their documentation.

Below is a simple bash script I used to help me automate the process when I was building the EncFS extension for TC. Note, I am not the author of EncFS. I only compiled a build and packaged it for TinyCore Linux.

There are some major steps in the build process missing here, but you may find some helpful pointers. The documentation I linked to above from TinyCore is the best source of truth when it comes to the packaging process. 

#!/bin/sh

# Required extensions to build (and to package and submit)
tce-load -wi submitqc6 git coreutils squashfs-tools automake gettext m4 pkg-config libtool-dev sed glibc_base-dev gcc linux-3.16.2_api_headers fuse openssl-1.0.1-dev rlog rlog-dev make boost-dev

# Notes: -fno-exceptions -fno-rtti caused compilation errors. Do not use.

# **build**

cd /tmp && git clone https://github.com/vgough/encfs && cd encfs

autoreconf -if

export CFLAGS="-march=i486 -mtune=i686 -Os -pipe"
export CXXFLAGS="-march=i486 -mtune=i686 -Os -pipe"
export LDFLAGS="-Wl,-O1"

./configure --prefix=/usr/local

touch /tmp/mark

make -j3

make DESTDIR=/tmp/package install-strip

# **package**

PACKAGE=encfs

mkdir -p /tmp/package/usr/local/share/doc/$PACKAGE
cp -f /tmp/encfs/COPYING* /tmp/package/usr/local/share/doc/$PACKAGE

(cd /tmp && mksquashfs package $PACKAGE.tcz)

(cd /tmp/package && find usr -not -type d > /tmp/$PACKAGE.tcz.list)

rm -f /tmp/$PACKAGE.tcz.dep

for dep in "openssl-1.0.1" "rlog" "boost" "fuse"
do
  echo "$dep.tcz" >> /tmp/$PACKAGE.tcz.dep
done

(cd /tmp && md5sum $PACKAGE.tcz > $PACKAGE.tcz.md5.txt)

Do this after the .tcz.info file is available to properly audit your build. 

(cd /tmp && submitqc6)
