Bug 122042 – flex-2.5.31 doesn't declare isatty for C++ code

• Status: RESOLVED DUPLICATE of bug 119598
• Product: Gentoo Linux

[Description Kenton Groombridge 2006-02-07 14:23:08 UTC]

In my attempts to fix a previous bug I entered:

http://bugs.gentoo.org/show_bug.cgi?id=120880

I did a:

emerge -e transcode

When it got to x11-apps/ttmkfdir-3.0.9-r3, it failed with:

 i686-pc-linux-gnu-g++ -Wall -pedantic -I/usr/include/freetype2 -pipe -march=athlon-xp -fomit-frame-pointer -mmmx -msse -m3dnow -mfpmath=sse -c builtin.cpp -o builtin.o >/dev/null 2>&1

!!! emake failed
!!! If you need support, post the topmost build error, and the call stack if relevant.

Google searched for possible solutions, but nothing I did worked and repeated attempts to build this package result in the same failure.

Thanks,
Ken

(re)emerge sys-devel/flex and try again...

[Comment 2 Kenton Groombridge 2006-02-07 16:36:54 UTC]

Performed an emerge of sys-devel/flex and then emerged ttmkfdir with the same results.

I posted the problem building transcode some time ago, and I am curious why nobody else seems to be posting any "me too" comments.

Is it possible that I may have some hardware failure (CPU) that could be causing these?

Thanks for your hard work.

Ken

[Comment 5 Alexey Maximov 2006-02-08 06:40:27 UTC]

just try downgrade flex ?

[Comment 6 Marien Zwart (RETIRED) 2006-02-08 06:43:53 UTC]

This looks like bug 13681 resurfaced. It merges for me with flex-2.5.4a-r6, but not with flex-2.5.31-r1.

[Comment 7 David Moxey 2006-02-08 10:57:15 UTC]

Ran into the same problem myself. An easy fix for those who want to compile straight away:

On line 1587 of parser.cpp, change:
  extern int isatty (int );
to:
  extern int isatty (int) throw();

then re-emerge with FEATURES="keepwork". This is my first post on here; seems to work, but I have no idea whether it'll cause problems down the line :-) 

[Comment 8 Vedran Miletić 2006-02-08 13:32:45 UTC]

I was just about to post a "me too" comment. But David's suggestion fixes it. Thanks a lot, David!

Comment on attachment 79268 [details, diff]
flex-2.5.31-isatty.patch

Rebuild flex with this patch (replace the existing one) to fix this bug. By the way I'm using a glibc overlay so I'm not sure if flex has the same problem with the glibc in portage.
