hashdeep installation for SmartOS Global Zone (GZ)

This repository contains fixes for building and installing hashdeep on SmartOS Global Zone.

The problems

hashdeep has four compilation issues on SmartOS/Illumos:

1. Missing assert.h / __assert error: On SmartOS with -D_FORTIFY_SOURCE=2, assert() expands to __assert() which isn't linked
2. algorithm_t initialization: The algorithm_t array cannot be default-constructed
3. Strict compiler flags: -Weffc++ and -Werror treat style warnings as fatal errors
4. C++11 literal spacing: PRI macros (PRId64, PRIu64, etc.) need space before them in string literals

Solution

1. Include smartos_assert.h workaround header that provides a working assert implementation
2. Initialize the hashes array with = {} syntax
3. Remove strict warning flags from the build configuration
4. Add spaces between string literals and PRI macros (e.g., "%" PRId64 instead of "%"PRId64)

I do not knwo how to make patches, so I made short scripts instead.

Installation

install-hashdeep.sh will git clone hashdeep, apply all fixes, and compile automatically:

Steps

In a SmartOS Global Zone (GZ):

cd /opt
curl -L https://raw.githubusercontent.com/barishanghosh/smartos-hashdeep-install/master/install-hashdeep.sh | bash

This will clone https://github.com/jessek/hashdeep.git, apply the fixes and compile it.

Make sure to have all the pkgsrc tools available, including gmake, gsed, etc.

Note: I am quite new to SmartOS, pkgsrc and coding. but I would be happy to learn how to make a pkgsrc package from this.
