Modifications to makefiles of binutils and gcc-4.4 to compile for alternate prefix directories
The following are patch files that I apply to the binutils and gcc-4.4
in order to get them to build for use at an alternate prefix. I post
these for general interest and discussion. I use these modifications to
create tools that can be installed under /opt/.. instead of /usr/.. in
support of a generic cross building environment that is stand alone and
not specifically tied to a Debian environment.
In order to build the tools with an alternate build prefix, I need to
make some manual changes to the makefiles of the binutils and gcc
packages prior to compilation. These changes turn out in fact to be
fairly trivial and generic, simply some replacement of hardcoded '/usr'
paths with a prefix variable that defaults to '/usr' if it is not
already defined (e.g. by passing on the command line). In fact, the gcc
package had nearly everything I needed already in place, and already
mostly supported the alternate prefix.
In general to build these toolchains, I follow the method described here
http://wiki.debian.org/EmdebianToolchain under the heading 'Build your
own from sources'. Once I have made the following modifications to the
three makefiles listed, I can change the prefix directory of the
resulting tools by specifying the PF environment variable on the command
line as follows by example:
For binutils
jheck@squeeze2:~/opt-build/binutils-2.20.1$
PF=/opt/crosscompiler/gcc-4.4.4/arm TARGET=armel fakeroot debian/rules
binary-cross
For gcc-4.4
jheck@squeeze2:~/opt-build/gcc-4.4-4.4.4$
PF=/opt/crosscompiler/gcc-4.4.4/arm GCC_TARGET=armel DEB_CROSS=yes
fakeroot debian/rules control
jheck@squeeze2:~/opt-build/gcc-4.4-4.4.4$
PF=/opt/crosscompiler/gcc-4.4.4/arm DEB_CROSS_NO_BIARCH=yes
GCC_TARGET=armel DEB_CROSS=yes dpkg-buildpackage -us -uc -rfakeroot
Here are the diff files as they apply to the specific source package
versions listed.
