при использовании pdftk для извлечения страниц в файле Makefile команда pdftk всегда выполняется независимо от того, изменился ли файл pdf предварительного просмотра или нет.pdftk в Makefile каждый раз запускается при выполнении
document.tex:
\documentclass[10pt]{article}
\begin{document}
Page one
\newpage
Page two
\end{document}
Сделать файл PDF:
pdflatex document.tex
Makefile:
all: document page-one
document: document.tex
pdflatex $<
page-one: document
pdftk A=$<.pdf cat A1 output PageOne.pdf
Каждый раз, когда я
make all
Выполняется команда pdftk. Я бы хотел только извлечь страницу, если родительский документ изменился. Есть идеи? В конечном итоге команда pdflatex также войдет в Makefile, но для того, чтобы выделить проблему, я ее оставил.
Edit:
Пожалуйста, обратите внимание, что я изменил Makefile для ясности. И вот два прогона по запросу.
Первый запуск производит
$ make -dRr page-one

Что 'делает -d' (' сделать -dRr', если это работает поможет сократить выход существенно), скажем, когда вы запускаете его в одном из случаев, когда вы считаете, что он не должен запускаться 'pdftk'? –
