GNU Make 問題

mathfeel

我在用gnuplot來畫圖。它會弄出两個檔案：%.tex和%-inc.eps、
然後跑epstopdf 來制造%-inc.pdf、
最後跑pdflatex來制造%.pdf。

為了方便，我寫了一個Makefile：

1. figTEX=figGBL_LL_Vb0.tex figGBL_LL_Vb3.tex
   
2. 
   
3. figPDF=$(figTEX:tex=pdf)
   
4. 
   
5. figEPS=$(figTEX:tex=eps)
   
6. figEPSi=$(figTEX:.tex=-inc.eps)
   
7. 
   
8. # ANSI color codes
   
9. RS=\\033[0m
   
10. FRED=\\033[31m
    
11. FGRN=\\033[32m
    
12. 
    
13. all: $(figEPS) $(figPDF)
    
14. 
    
15. %-inc.pdf : %-inc.eps
    
16.         @echo Running $(FRED)epstopdf$(RS) to make $@ from $(FGRN)$?$(RS);
    
17.         @epstopdf $<;
    
18. 
    
19. %.pdf : %.tex %-inc.pdf
    
20.         @echo Running $(FRED)pdflatex$(RS) to make $@ from $(FGRN)$?$(RS);
    
21.         @pdflatex -interaction=nonstopmode $< > /dev/null;
    
22. 
    
23. %.eps : %.tex %-inc.eps
    
24.         @echo Running $(FRED)latex/dvips$(RS) to make $@ from $(FGRN)$?$(RS);
    
25.         @latex -interaction=nonstopmode $< > /dev/null;
    
26.         @dvips -E -o $@ $(<:tex=dvi) 2>1 > /dev/null;
    
27.         rm $(<:tex=dvi);
    
28. 
    
29. $(figTEX) $(figEPSi) : GBL_LL.gpi
    
30.         @echo Running $(FRED)gnuplot$(RS) to make $@ from $(FGRN)$?$(RS);
    
31.         @gnuplot $<;

執行結果

1. $ touch *gpi && make
   
2. Running gnuplot to make figGBL_LL_Vb0.tex from GBL_LL.gpi
   
3. Running latex/dvips to make figGBL_LL_Vb0.eps from figGBL_LL_Vb0.tex figGBL_LL_Vb0-inc.eps
   
4. rm figGBL_LL_Vb0.dvi;
   
5. Running latex/dvips to make figGBL_LL_Vb3.eps from figGBL_LL_Vb3.tex figGBL_LL_Vb3-inc.eps
   
6. rm figGBL_LL_Vb3.dvi;
   
7. Running epstopdf to make figGBL_LL_Vb0-inc.pdf from figGBL_LL_Vb0-inc.eps
   
8. Running pdflatex to make figGBL_LL_Vb0.pdf from figGBL_LL_Vb0.tex figGBL_LL_Vb0-inc.pdf
   
9. Running epstopdf to make figGBL_LL_Vb3-inc.pdf from figGBL_LL_Vb3-inc.eps
   
10. Running pdflatex to make figGBL_LL_Vb3.pdf from figGBL_LL_Vb3.tex figGBL_LL_Vb3-inc.pdf
    
11. rm figGBL_LL_Vb0-inc.pdf figGBL_LL_Vb3-inc.pdf

我想問為甚麼有最後一行？我的Makefile里面没有任何rm pdf的指令。
