Fix patch for Makefile problem
This patch should solve the problem. When building with a separate module
directory tree, the current directory (and therefore relative paths) are in the
object directory tree, not the source tree. In order to make standard includes
work in that case, the KBUILD_SRC define is set and the srctree variable points
to the toplevel src directory. We add an include that specifies
$(srctree)/<normal include path> into the include list and then our includes
are found like normal.
committed in stream U4 build 40.1. A test kernel with this patch is available from http://people.redhat.com/~jbaron/rhel4/ Verified based on existing rhts results. s390x fails but that failure is due to BZ 197743. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2006-0575.html |
Description of problem: Appears the latest changes to the infinband drivers introduce a build problem for those who like to build kernel objects outside of the source directory (using make O=/objdir). Version-Release number of selected component (if applicable): RHEL4, kernel 2.6.9-39.4 How reproducible: 100% Steps to Reproduce: 1. Install kernel SRPM (rpm -i kernel-2.6.9-39.4.EL.src.rpm) 2. cd /usr/src/redhat/SPECS 3. rpmbuild --target=i686 -bp kernel-2.6.spec (or as appropriate) 4. mkdir /objdir 5. cd /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9 6. cp configs/kernel-2.6.9-i686-smp.config (or as appropriate) /objdir/.config 7. make O=/objdir oldconfig 8. make O=/objdir The build will then commence, but will fail with this message: /usr/src/redhat.old/BUILD/linux-2.6.9-39.4EL/drivers/infiniband/core/index.c:36:25: > linux/index.h: No such file or directory Actual results: Build failure Expected results: Build success Additional info: If the build is done in-tree (without the O= build flag), the build will succeed. This behaves much like the build problem introduced with the lpfc driver import a short while ago.
