This page describes the process of creating ILP32 support for LEAP.

GCC:

  • I downloaded gcc-4.9.2. I got mine from http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=255322.
  • I created a scratch build for that rpm, which is accessible here: http://blue/koji/taskinfo?taskID=83468.
  • I downloaded the source rpm from that build and manually downloaded and installed required dependencies from the same place.
  • I run "rpm -i gcc-4.9.2-6.bb4.src.rpm" to install it on AArch64 builder.
  • I went in the "~/rpmbuild/SPEC" directory, and run command "rpmbuild -bp gcc.spec" to get the prep stage on the rpm.
  • I created a git repository (https://github.com/ArtemL/GCC), copied "~/rpmbuild/BUILD/gcc-4.9.2-20150212/" directory into it, and pushed it.
  • I changed "~/git/GCC/gcc-4.9.2-20150212/configure" in the next ways:

  • I committed the changes and run "git format-patch master --stdout > gcc49-makefile.patch" command to get the patch for my changes.
  • I copied "gcc49-makefile.patch" to "~/rpmbuild/SOURCES/"

I edited "~/rpmbuild/SPECS/gcc.spec" in the next way:

  • I run "export RPM_PACKAGER="Artem Luzyanin <artem.luzyanin@senecacollege.ca>""
  • I run "rpmdev-bumpspec -c "This patch is to create ilp32-capable gcc in a separate tree."" command to add the changes with comments to the spec file.
  • I run "rpmbuild -ba --nocheck gcc.spec" command to get the rpms.

I run "rpm " command to check that all gcc files will be installed in the correct place.

GLIBC:

  • I downloaded glibc-2.17 source rpm. I got mine from http://blue/kojifiles/packages/glibc/2.17/78.bb4/src/glibc-2.17-78.bb4.src.rpm.
  • I downloaded and installed required dependencies from the same place.
  • I run "rpm -i glibc-2.17-78.bb4.src.rpm" to install it on AArch64 builder.
  • I went in the "~/rpmbuild/SPEC" directory, and run command "rpmbuild -bp glibc.spec" to get the prep stage on the rpm.
  • I created a git repository, and pushed the content of "~/rpmbuild/BUILD/glibc{some random numbers}" directory to it to get the original information in it.
  • I went in the "~/rpmbuild/BUILD/glibc{some random numbers}" directory.

I changed "configure" file in the next ways: I run "./configure" command. I changed "Makefile" file in the next ways:

  • I run "make" command, then waited for the make for a long period of time for it to be complete (around 7 hours).
  • I committed the changes and run "git diff --patience master glibc21-leap-ilp-32 | filterdiff --format=context > ../glibc21-leap-ilp-32.patch" command to get the patch for my changes.
  • I run "export RPM_PACKAGER="Artem Luzyanin <artem.luzyanin@senecacollege.ca>""
  • I run "rpmdev-bumpspec -c "This patch is to create ilp32-compiler libraries of glibc in a separate tree."" command to add the changes with comments to the spec file.

I changed "~/rpmbuild/SPEC/glibc.spec" file in the next way: I run "rpmbuild -bs glibc.spec" command to get the source rpm.
