Description Michal Nowak 2010-05-07 06:29:07 EDT
Description of problem:

I have here systemtap-1.2-1.el6.src.rpm which I'd like to rebuild. Some BRs are missing so I run `yum-builddep systemtap-1.2-1.el6.src.rpm` it resolves them and installs. Then I try to rebuild package `rpmbuild --rebuild systemtap-1.2-1.el6.src.rpm` but it fails:

[root@auto-i386-001 ~]# rpmbuild --rebuild systemtap-1.2-1.el6.src.rpm 
Installing systemtap-1.2-1.el6.src.rpm
error: Failed build dependencies:
	crash-devel is needed by systemtap-1.2-1.el6.i686

systemtap spec file looks like this:

%ifarch ppc
# crash is not being built on rhel6 beta on ppc
%{!?with_crash: %global with_crash 0}
%{!?with_crash: %global with_crash 1}


%if %{with_crash}
BuildRequires: crash-devel zlib-devel


%if %{with_crash}
Requires: crash


It seems that yum-builddep fails to resolve BuildRequire if it is "hidden" by %global definition.

Version-Release number of selected component (if applicable):


How reproducible:

always. all archs.

Expected results:

crash-devel resolved & installed as others BRs.

Comment 2 seth vidal 2010-05-07 09:06:04 EDT
can you run:

rpm -qpR systemtap-1.2-1.el6.src.rpm

I suspect the buildreq is not listed there, either.

yum-builddep cannot read the spec file and parse the deps that show up there. It only gets the buildreqs from the requires in the src rpm header.
Comment 3 James Antill 2010-05-07 09:52:20 EDT
Specifically, this is the same "bug" as using %{_isa} in BuildRequires ... they are then "fixed" at the point rpmbuild creates the .src.rpm, so you either need to create a .src.rpm for each arch. ... or do something else.

I can see. Thanks for clarification.
