And a small addition to that: # Makefile
all: result.txt
targets = a.txt b.txt c.txt d.txt
$(targets) &:
touch a.txt b.txt c.txt d.txt
result.txt: $(targets)
touch result.txtSame Example as in the details above# Makefile 'old version'
all: build/v16516.pdf
# hier Python-Skripte:
build/plot-g_ball.pdf: auswertung.py ../matplotlibrc ../header-matplotlib.tex data/*| build
# so that matplotlib can find the tex header when running
# LaTeX in the tmp directory
# and set the matplotlibrc

Another thing I found working on the lab report:
The context:
For the most extensive solution (exporting every value from the python script into a tex file) I added the manual synchronization from the last `make` -slide:does not look very nice in my opinion ... and it is also somewhat tedious to write
... though come to think of it, might be a prime example for multiline editing 🤔
I found a relatively recent addition to Make (4.3), so called 'grouped targets'
docs
grouped targets are all created by just on execution of the specific rule.
So the manual changing for parallel processing is not necessary.
Example
results in
> make -j4 touch a.txt b.txt c.txt d.txt touch a.txt b.txt c.txt d.txt touch a.txt b.txt c.txt d.txt touch a.txt b.txt c.txt d.txt touch result.txt> make -j4 touch a.txt b.txt c.txt d.txt touch result.txtThe text was updated successfully, but these errors were encountered:
