Recompile a source rpm your own way

Prev		Next

Howto

rpm -ih emacs-21.2-18.src.rpm

or,

apt-get source emacs

cd /usr/src/redhat/

change

        %configure --with-gcc --with-pop --with-sound
to

%configure --with-gcc --with-pop --without-sound --without-toolkit-scroll-bars

in SPECS/emacs.spec

Increase Release number, so that ours won't get overwritten during apt-get upgrade. E.g, Change "Release: 18" to "Release: 18.1"

Get dependent rpms (XFree86-devel ncurses-devel libpng-devel libjpeg-devel libungif-devel libtiff-devel) and istall them. or better,

apt-get build-dep emacs

Then,

rpmbuild -bb SPECS/emacs.spec

Then,

move out built rpm:

cd ...
mv /usr/src/redhat/RPMS/i386/emacs-2*.i386.rpm .
rpm -Uh emacs-2*.i386.rpm

-bb    Build a binary package  (after  doing  the  %prep,  %build,  and
       %install stages).

+ echo 'Patch #1 (emacs-21.2-pop.patch):'
Patch #1 (emacs-21.2-pop.patch):
+ patch -p1 -s
+ exit 0

-bp    Executes  the  "%prep"  stage  from the spec file. Normally this
       involves unpacking the sources and applying any patches.

cd BUILD/emacs-21.2
configure --without-toolkit-scroll-bars

— I want standard x-scrollbar behavior

make

src/emacs &

— test run ok

make install

— do it manually! Do NOT use the 'rpmbuild -bi' command:

-bi    Do  the  "%install"  stage  from  the spec file (after doing the
       %prep and %build stages).  This generally involves  the  equiva-
       lent of a "make install".

It wipe off all my previously build when I tried!

# Tried to build rpms out of my current build but failed:

% rpmbuild -bb --nobuild SPECS/emacs.spec
[...]
RPM build errors:
    Could not open %files file /usr/src/redhat/BUILD/emacs-21.2/core-filelist: No such file or directory
    Could not open %files file /usr/src/redhat/BUILD/emacs-21.2/el-filelist: No such file or directory
    Could not open %files file /usr/src/redhat/BUILD/emacs-21.2/leim-filelist: No such file or directory

make uninstall

— very important! It installs emacs to /usr/local/bin/emacs, not the place specified by rpm!

Attempt 2

How about I build it first? Will the files be generated then?

cd /usr/src/redhat
rpmbuild -bc SPECS/emacs.spec

cd BUILD/emacs-21.2
configure --without-toolkit-scroll-bars
# -- I want standard x-scrollbar behavior
make

src/emacs &
# -- test run ok

cd /usr/src/redhat
rpmbuild -bi --nobuild SPECS/emacs.spec
[...]
RPM build errors:
    Could not open %files file /usr/src/redhat/BUILD/emacs-21.2/core-filelist: No such file or directory
[...]

Attempt 3

Seems that I have to do build-install to get those files generate:

rpmbuild -bi SPECS/emacs.spec
rpmbuild -bb --nobuild SPECS/emacs.spec
# -- no rpms written

Help

Do not use —rebuild or —recompile. When invoked as,

rpmbuild --rebuild|--recompile SOURCEPKG ...

rpmbuild installs the named source package, and does a prep, compile and install.

According to man page, —rebuild builds a new binary package. When the build has completed, the build directory is removed (as in —clean) and the the sources and spec file for the package are removed.

I found that —recompile removes the build directory too! It leaves the spec file though.
