If you execute "crew install unzip", it will fail on ARM, due to an assembler related error (I assume that the unzip sources only contain x86 assembler, but no ARM asm). The error output looks like this:

I have therefore downloaded the Unzip sources myself from ftp://ftp.info-zip.org/pub/infozip/src/unzip60.zip , deflated it, copied the unix/Makefile over into the sources root directory and used:

make linux_noasm

The resulting build was successful, with no asm related errors.

The relevant line is line 25 in https://github.com/skycocker/chromebrew/blob/master/packages/unzip.rb :

Currently is reads:
system "make -f unix/Makefile generic"
But in order to fix the error, it would have to be:
system "make -f unix/Makefile linux_noasm"

This has been implemented via this commit.

(UPDATE) JDK8 armv7l binary.

Fix libpng url

Fixes #233 

skip tests because at least one test wants to write to /

add unzip package

(UPDATE) README - Remove "Does not support arm chipsets yet" and replace with a table.

Added sha256 of arm ruby to install.sh script

(UPDATE) Nano to 2.7.1

(UPDATE/FIX) JDK8

(UPDATE) GO to 1.7.4

(UPDATE) HTOP to 2.0.2

(UPDATE) NGINX Change stopnginx to run "sudo nginx -s quit" instead of "sudo pkill nginx"

(FIX) Checksum Mismatch on PCRE

ARM support (tested on c100pa)

upstream code isn't maintained any more, many distros have unofficial
patch sets, so we use the full ubuntu patch set.  Includes several
security vulnerabilities

Make symbolic link between /usr/local/nginx/sbin/nginx and /usr/local/bin/nginx be forced otherwise it fails.

Probably copy/pasted wrong.

stopnginx now stops nginx gracefully instead of just killing the process.

Changed url and sha1 and crew package version number
