I have a makefile(s) that runs fine with --jobs=1 but when I run with --jobs=X
(X>1) it fails.
I know exactly why; it's because I have entries like this:
t1:
mkdir d1
create_makefile.bat > ./d1/makefile
t2:
cd d1
make -f makefile
Target t2 depends on t1 but that's not stated in the makefile.
With -j1, this runs fine (because of the order of the targets in the makefile).
However with -jX X>1, I eventually get an error due to race conditions.
I have dozens of makefiles so I need an automated solution to detect these
implicit dependencies.
The `--print-data-base` doesn't help me because make doesn't detect
filesystem-level actions i.e.
the `--print-data-base` entry for `t1` won't tell me that `t1` created a
directory `d1` and a makefile `./d1/makefile` and yes,
I understand that this functionality is outside the scope of `make` but hoping
that someone has an idea how to solve this.
What I need is an OS utility that will detect every read/write action my build
performs AND the ability to attribute
those filesystem-level operations to the makefile target that performs them.
I'm in Windows so I found Sysinternals Process Monitor
https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx
but I still need to figure out how to synchronize the two (make and process
monitor).
Process monitor outputs every single event with microsecond accuracy but I have
no way of timestamping my targets.
Anyone have a more elegant solution?
There exists a paid solution already - Huddle by Electric-Cloud - but would be
nice for a free one also.
