It's your build environment that's the problem. They build for el5.
Clean out your build root and recreate it and do a fresh .rpmmacros

I'm trying to understand your instructions. I think my build environment
is not too bad. I build many other rpms from spec files. Most of those
spec files have a line exactly like or similar to:
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)
but this libsrtp.spec file does not. So it appears that at the point where
DESTDIR is specified, the literal value '%{buildroot}' is used.
In my trace ... make install 'DESTDIR=%{buildroot}'
In yours ... make install
DESTDIR=/home/ethan/rpmbuild/BUILDROOT/libsrtp-1.4.4-2.20101004cvs.el5.em2.x86_64
BTW, here is fedoraproject info on BuildRoot:
[url]https://fedoraproject.org/wiki/EPEL/GuidelinesAndPolicies#BuildRoot_tag[/url]
I bet I can make it work by adding a BuildRoot: line to the spec file.
Where/how is %{buildroot} defined in your build environment?
Are you building on a CentOS/RHEL 5.X machine?
I have simplified my ~/.rpmmacros file to just these two lines:
$ cat ~/.rpmmacros
%_topdir/home/bbeers/redhat/
%_smp_mflags -j3
and I still get the same errors.

Yep, that make sense.
For completeness, there is another mod to the spec file that is

Well, it is recommended in the same fedoraproject reference from

'rpmbuild --rebuild ...' using my newly constructed el5.src.rpm.
So, another alternative to the spec file modification would be an

Again looking at this site: http://www.rsyslog.com/doc/manual.html, specifically http://www.rsyslog.com/doc/troubleshoot.html, give these three hints on troubleshooting: 1) - Configuration Problems Rsyslog 3.21.1 and above has been enhanced to support extended configuration checking. It offers a special command line switch (-N1) that puts it into config verfication mode. In that mode, it interprets and check the configuration file, but does not startup. This mode can be used in parallel to a running instance of rsyslogd. To enable it, run rsyslog interactively as follows: /path/to/rsyslogd -f/path/to/config-file -N1 You should also specify other options you usually give (like -c3 and whatever else). Any problems experienced are reported to stderr [aka your screen (if not redirected)]. 2) - Debug Log In general, it is advisable to run rsyslogd in the foreground to obtain the log. To do so, make sure you know which options are usually used when you start rsyslogd as a background daemon. Let's assume -c3 is the only option used. Then, do the following: * make sure rsyslogd as a daemon is stopped (verify with ps -ef|grep rsyslogd) * make sure you have a console session with root permissions * run rsyslogd interactively: /sbin/rsyslogd ..your options.. -dn logfile where your options is what you usually use. /sbin/rsyslogd is the full path to the rsyslogd binary (location different depending on distro). In our case, the command would be /sbin/rsyslogd -c3 -dn logfile * press ctrl-C when you have sufficient data (e.g. a device logged a record) NOTE: rsyslogd will NOT stop automatically - you need to ctrl-c out of it! * Once you have done all that, you can review logfile. It contains the debug output. * When you are done, make sure you re-enable (and start) the background daemon! 3) - http://www.rsyslog.com/doc/debug.html HTH, -Bob ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] wan hdlc_ppp and IPv6
Hi list, I can successfully build the driver modules; hdlc, dlci, syncppp, and lmc from the 2.6.18-128.1.14 kernel source rpm, and have managed to create a 'wan kmod' rpm. It all works fine for IPv4, but now I need IPv6 for ppp connections, which doesn't work for me. I think I'll need to back port Krzysztof Halasa's 'ppp for generic hdlc' patches to the 2.6.18-128.1.14.el5 kernel sources. Has anyone worked on this? I have tried simply overwriting the drivers/net/wan directory with corresponding directory from more recent (2.6.25.20, 2.6.30) vanilla kernel source, but I get errors: CC [M] drivers/net/wan/hdlc.o drivers/net/wan/hdlc.c:39:31: error: net/net_namespace.h: No such file or directory drivers/net/wan/hdlc.c: In function ‘hdlc_rcv’: drivers/net/wan/hdlc.c:69: warning: initialization from incompatible pointer type drivers/net/wan/hdlc.c:71: error: ‘struct net_device’ has no member named ‘nd_net’ drivers/net/wan/hdlc.c:71: error: ‘init_net’ undeclared (first use in this function) drivers/net/wan/hdlc.c:71: error: (Each undeclared identifier is reported only once drivers/net/wan/hdlc.c:71: error: for each function it appears in.) drivers/net/wan/hdlc.c:76: error: dereferencing pointer to incomplete type drivers/net/wan/hdlc.c:77: error: dereferencing pointer to incomplete type drivers/net/wan/hdlc.c: In function ‘hdlc_proto_start’: drivers/net/wan/hdlc.c:85: error: invalid type argument of ‘-’ ... and so on.

There is one problem with this approach, which is the assumption that all users' primary group is the same as their login id - which I agree is typically the RHEL way, but it doesn't have to be the case. If however you have users with their primary group set to something other than the login id - e.g. admin or marketing - then you need to look in the /etc/passwd file as well because these users don't appear in the comma separated list outlined above. To check the /etc/passwd file, you have to determine the group id value, and then scan the /etc/passwd file looking for that value in column 4. This will give you a list of users whose primary group is the group value you're interested in. You have a valid point, but the OP's question was: I am looking for a (simple) shell command to run from a bash script that will allow me to list user accounts that belong to a particular group.

Not by looking at the RPM .. but you can look in the build log (if you have
one). Here is the line for i386 for openssh-4.3p2-26.el5:

Notice that the assignment contains spaces, single-quotes and double-quotes, maybe god-only-knows-what-else. It's untrusted data. Yet I need to pass it all *safely*. The appropriate function in PHP is addslashes(); but what is the bash equivalent? EG: short answer: single quotes will handle all characters, except single quotes. long answer: man bash the section called QUOTING may help you figure a solution. #! /bin/sh A=This isn't a \parameter\; B=`/path/to/somecommand.sh $A`; exit 0; Thanks, -Ben HTH, -Bob ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Cron on certain days?

I think you can make cronjob run on every Friday, and in your script check if date is 2nd (3rd) Friday. OTOH, if you specify days and day of week, I think they will both match, which is not what you want. I found this with google: http://www.computing.net/unix/wwwboard/forum/2731.html Which leads to something along these lines ... day=`date +%d` if [ $day -ge 8 -o $day -le 14 ]; then echo javascript:void(0) '2nd Friday' # do F2 elif [ $day -ge 15 -o $day -le 21 ]; then echo javascript:void(0) '3rd Friday' # do F3 fi HTH, -Bob ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Cron on certain days?
Sloppy cut-n-paste error using -o, so this is obviously wrong ... day=`date +%d` if [ $day -ge 8 -o $day -le 14 ]; then echo '2nd Friday' # do F2 elif [ $day -ge 15 -o $day -le 21 ]; then echo '3rd Friday' # do F3 fi maybe something more like this: day=$(date +%d) [[ $day -le 7 ]] echo 1st Friday do_F1 exit [[ $day -ge 8 $day -le 14 ]] echo 2nd Friday do_F2 exit [[ $day -ge 15 $day -le 21 ]] echo 3rd Friday do_F3 exit [[ $day -ge 22 $day -le 28]] echo 4th Friday do_F4 exit -Bob ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
