@unixfreaxjp next time please open issue on https://github.com/radare/radare2 repo not "radare"

Done.

@radare commented 7 minutes ago
cant reproduce

It was occured in x32/gcc 4.2.1 20070831 patched [FreeBSD]
Let's see if this occured in x86-64 & amd64 FreeeBSD too (hold on..)

radare · 2016-11-29T11:08:22Z

i have tested on freebsd-amd64, linux-arm and osx-x86-64, no issues at all

Retrying now. @Maijin

XVilka · 2016-11-29T11:36:29Z

The solution is to eliminate anonymous union.

unixfreaxjp · 2016-11-29T11:37:59Z

@XVilka @Maijin @radare
build error is persisted. In union initial part.
It was well before in last week compilation.. same cc (GCC) 4.2.1 20070831 patched [FreeBSD]
This is gcc compatibility problem..

@XVilka @Maijin @radare

all of our dev systems is using gcc 4.2.1,
what should I do to make this work?

XVilka · 2016-11-29T11:43:58Z

Someone will do the fix today, just not right now.

unixfreaxjp · 2016-11-29T12:01:06Z

I will urgently plan upgrade gcc on many of the bsd analysis clusters then. We use servers to analyze UNIX bad stuff, not client.. upgrading gcc will upgrade ton of dev stuff too..
Taking off the urgent flag. Will re-open the issue if still persist after using recent gcc.
Thank's for the answers, appreciated. If any solution for this, please help.
One urgent analysis is in progress now, will use version RELEASE-0.10.5(PRECON) for quick workup, built well:

radare2 0.10.5 9999999 @ freebsd-x86-32 git.0.10.5

Cheers.

unixfreaxjp · 2016-12-01T05:39:54Z

@radare @XVilka @Maijin @unixfreaxjp @killabytenow
I still wonder since when gcc 4.2.1. is becoming incompatible, since I swear it was working few weeks back. Below is the report I run on several radare2 built for test under gcc 4.2.1 :

radare2-1.0 aka "Finally" works, proof:

$ date&&r2 -v
Thu Dec  1 14:37:04 JST 2016
radare2 1.0 9999999 @ freebsd-x86-32 git.1.0
commit: HEAD build: 2016-12-01

radare2 version 1.0.2 is also proven works / built fine:

$ date&&r2 -v
Thu Dec  1 14:44:38 JST 2016
radare2 1.0.2 9999999 @ freebsd-x86-32 git.1.0.2
commit: HEAD build: 2016-12-01

##The problem is sourced in here:##

There must be a code change in development after 1.0.2 RELEASE (November the 10th, 2016) that affects this good gcc compatibility quality that radare2 had before, I was just tracing it now, to find this commit code (on Nov 19, 2016 ), the code is here: 9d6bbf9 by @killabytenow is the source.

A policy in the development need to be decided on the anonymous union usage on the radare2 code. I leave this matter to the development tops to decide.

radare · 2016-12-01T08:27:06Z

yeah im not really a fan of anonymous unions, wondering if there's any gcc flag to enforce this

radare · 2016-12-01T08:28:02Z

why this issue is closed if its not fixed?

unixfreaxjp · 2016-12-01T09:39:49Z

why this issue is closed if its not fixed?

Because I know that you are busy.. and people can use workaround to use 1.0.2,

wondering if there's any bcc flag to enforce this

Believe me, I already on seeking that too. But there is no easy configure option that can be used for forcing this.

I agree for the @XVilka suggestion for the recoding without anonymous unions , or, we are accepting the limitation on used gcc version. It is the decision that you should make due to product's compatibility, quality, roadmaps are related.

unixfreaxjp · 2016-12-01T14:30:25Z

I tested 13c15cb (and to de-anonymize the AVR union ) on x86-32 and x86-64

32bit:
