Hi all,
I'm not a regular rpm builder, but have the need to build some at the
moment. I've been successful in building the few rpm's that I need
and now want to fine tune the process.
Please take a look at my .rpmmacros below. In particular, the addition
to the %configure macro in the last line (which is more like what I
want to do, am not sure of the syntax):
----------- start .rpmmacros ------------------------
%packager Ritesh Sood <riteshsood@xxxxxxxxx>
%vendor Dept. of ECE, UC Davis (Internal Use)
%_topdir %(echo $HOME)/ECESysAdmin/Syslog-ng/RPM-Build
%configure \
CFLAGS="${CFLAGS:-%optflags}" ; export CFLAGS ; \
CXXFLAGS="${CXXFLAGS:-%optflags}" ; export CXXFLAGS ; \
./configure --host=%{_host} --build=%{_build} \\\
... (original code from /usr/lib/rpm/macros) ...
%{?pkg_config_flags}
----------- end .rpmmacros ------------------------
The idea being that if I want to build the package ``pcre-ece" which
requires configure time flags, the spec file would be something like
----------- start pcre-ece.spec ------------------------
%define name pcre-ece
%define orig_name pcre
%define version 7.8
%define release 1
%define _prefix /usr/local
%define _docdir %{_datadir}/doc/%{orig_name}
%define pkg_config_flags --enable-unicode-properties --enable-
pcregrep-libz --enable-pcregrep-libbz2
--disable-pcretest-libreadline
Summary: Perl-compatible regular expression library
Name: %{name}
Version: %{version}
Release: %{release}
Source: %{orig_name}-%{version}.tar.bz2
URL: http://www.pcre.org/
License: BSD
Group: System Environment/Libraries
BuildRoot: %{_builddir}/%{orig_name}-root
Prereq: /sbin/ldconfig
BuildPrereq: sed
.
.
.
----------- end pcre-ece.spec ------------------------
Coming back to ``%{?pkg_config_flags}" in .rpmmacros above, the idea
being that if the spec file defines ``pkg_config_flags", then it would
be appended to the default expansion of the ``configure" macro; if
not, nothing would be appended. The ``?" in the above is a conjectured
syntax to achieve what i've stated above.
I'm not able to find good documentation on the syntax and rules of
these macros (i'm familiar with those of ``make"). Neither at
http://rpm.org/wiki/Docs#PackagerDocumentation
nor in the books
http://www.rpm.org/max-rpm-snapshot/
http://docs.fedoraproject.org/drafts/rpm-guide-en/
Any help in finding documentation is much appreciated.
Secondly, it would be good to have the facility to append per-package
flags to other macros. I found the following in one of Suse linux's
RPM spec file
----------- start code ------------------------
%build
%{expand: %%define optflags %{optflags} -fPIC}
----------- end code ------------------------
So just to add the ``-fPIC" flag, poor guy has to write all that code.
How about something like the following appearing in the ``configure"
macro instead:
----------- start code ------------------------
CFLAGS="${CFLAGS:-%optflags:-%{?pkg_cflags}}" ; export CFLAGS ; \
CXXFLAGS="${CXXFLAGS:-%optflags:-%{?pkg_cxxflags}}" ; export
CXXFLAGS ; \
----------- end code ------------------------
and while we're at it, might as well add
----------- start code ------------------------
LDFLAGS="${LDFLAGS:-%{?pkg_ldflags}}" ; export LDFLAGS ; \
----------- end code ------------------------
Again, the syntax is my guess as to what it might look like, but you
get the idea.
Looking forward to feedback on the above suggestions.
Ritesh
