Fixed In Version: make-4.2.1-11.el8
Doc Type: Bug Fix
Doc Text:
.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 Carlos Santos 2021-09-14 19:20:35 UTC
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.

This has been upstream a long time ago:

    https://savannah.gnu.org/bugs/?48274

The fix is also included in the Ubuntu package (also make v. 4.2.1).

This seems to be the key upstream commit:

Hi, can you do an SME review, please?

I tweaked it a bit but it's basically correct.

Comment 12 Jacob Taylor Valdez 2022-03-30 11:10:55 UTC
This has been acked from peer-review.
