Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
.The `-j` flag now works when used in a Makefile
Previously, when you added the `-j` flag to MAKEFLAGS inside the Makefile, the targets were built sequentially instead of in parallel. This bug has been fixed, and now the targets are built at the same time when you use the `-j` flag in the Makefile.
Description of problem:
The make command does not recognize the -j option in MAKEFLAGS.
Version-Release number of selected component (if applicable):
make-4.2.1-10.el8.x86_64
How reproducible:
Always
Steps to Reproduce:
$ cat Makefile
MAKEFLAGS := -j -s -B
all: t1 t2 t3 t4 t5 t6 t7 t8
t1 t2 t3 t4 t5 t6 t7 t8:
+echo begin
+sleep 10
+echo end
$ make
Actual results:
begin
end
begin
end
begin
end
begin
end
begin
end
begin
end
begin
end
begin
end
Expected results:
begin
begin
begin
begin
begin
begin
begin
begin
end
end
end
end
end
end
end
end
Additional info:
Using "make -j" produces the expected result, of course.
