Bug 103427 – dev-util/strace-4.5.12 fails to build if libaio installed

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Mathieu Seigneurin 2005-08-23 03:08:34 UTC]

strace-4.5.12 does not build if it finds libaio-0.3.15 installed.  
Seems that there is a mismatch between the declaration of iocb 
in libaio.h and what desc.c is expecting. 
libaio.h defines iocb.aio_data (and .aio_key) 
desc.c expects   iocb.data     (and .key) 

Reproducible: Always
Steps to Reproduce:
1. emerge libaio (0.3.15) 
2. emerge strace 
 
Actual Results:  
Error compiling desc.c:

then mv -f ".deps/ipc.Tpo" ".deps/ipc.Po"; else rm -f ".deps/ipc.Tpo"; exit 1;

Expected Results:  
Smoooth compile. 

Not sure if this is amd64 related, actually, but I don't have an x86 handy. 
Tentative patch will be attached.

Created attachment 66634 [details, diff]
fix iocb in desc.c

This is probably dependant on a recent libaio version...

fixed in cvs, thanks

Hi, 
 
I got hit by the problem tonight. 
 
So when does the fix goes from cvs into the life portage tree ? ;) 

[Comment 4 SpanKY 2005-11-13 20:53:44 UTC]

it's already in portage

[Comment 5 Erik Zeek 2005-11-17 11:30:43 UTC]

This patch breaks x86 strace ebuild with libaio-0.3.104.  This version of libaio
has the iocb.data and iocb.key members.

[Comment 8 SpanKY 2005-11-19 23:01:47 UTC]

should update configure to detect the proper member name of aio

[Comment 9 SpanKY 2005-11-19 23:34:25 UTC]

patch now checks to see what version of libaio it is building against and uses
the appropriate structure members
