Bug 165200 – sys-fs/evms fails on uclibc without UCLIBC_HAS_SYS_SIGLIST=y

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Aurélien Francillon 2007-02-04 00:51:15 UTC]

Hi, 
evms doesn't build/run when uclibc is built without UCLIBC_HAS_SYS_SIGLIST. However, this is the defautl under gentoo.
Is there any problem with adding SYS_SIGLIST as default ?
thanks 
Aurélien


Reproducible: Always

Please reopen with the error you get, thanks.

Hi, 
error when building against a non sys_siglist enabled uclibc:
...

if evms is build against sys_siglist enabled uclibc, and uclibc is rebuilt/updated with default config 
> evmsn                                                                                                                                                            
evmsn: symbol 'sys_siglist': can't resolve symbol in lib '/lib/libevms-2.5.so.0'.

a simple fix for this bug is to add  :
sed -i -e "s:# UCLIBC_HAS_SYS_SIGLIST.*:UCLIBC_HAS_SYS_SIGLIST=y:" .config
in src_unpack function of uclibc ebuild

thanks,
Aurélien

Created attachment 109134 [details, diff]
evms-2.5.5-no_sys_siglist.patch

A better fix is to get rid of the sys_siglist call in
evms/engine/dm-targets.c and replace it by a call to strsignal. Uclibc
devs seems to recommend that way according to /usr/include/signals.h


> #ifdef __UCLIBC_HAS_SYS_SIGLIST__
>  /* Names of the signals.  This variable exists only for compatibility.
>    Use `strsignal' instead (see <string.h>).  */

It builds with warnings if not built with " -D_GNU_SOURCE"

yep ... certainly nothing uClibc specific here; the glibc folks say you should stop using sys_siglist[] too

Hi, just to notify that the patch applies to 2.5.5-r10 as well, 
any chance to get it into next revision of evms-patches-2.5.5-1.tbz2 ? 
or should it be sent upstream ?
thanks 
Aurélien

sys-fs/evms has been removed from portage tree
