GNU Make只执行10条规则

Question

I have a makefile that shall convert some files into PDFs. Right now the makefile looks like this:

PDFS = file_A.pdf file_B.pdf <snip> file_K.pdf

all : convert

file_%.pdf:
    $(CONVERTER_COMMAND) $< -o $@

file_A.pdf : file1.ext
file_B.pdf : file2.ext
<snip>
file_K.pdf : file11.ext

convert : $(PDFS)
.PHONY : convert

The above is the general structure (unfortunately I can't show the actual file).

Running make convert works like a charm for the first 10 files, ie it generates file_A.pdf up until file_J.pdf . The last one however, file_K.pdf , is never generated. If I move the rule for it to the top of the list it gets generated, but then the now last one in the list no longer gets generated.

If I do make file_K.pdf make just state the file is up to date , even though it does not yet exist.

Any ideas? Or any alternative ideas on how to solve similar problems?

Answer 1

Is there a stray TAB character on the line after the last prerequisite statement (after file_K.pdf : file11.ext in the list above)?

You should try running make -d and see what it has to say about the targets that it doesn't build.
