我想要一个包含任意数量的 .tex 文件的文件夹，我将在其中拥有一个 Makefile，它会在make运行时为每个 .tex 文件生成一个 .pdf 文件。我的限制是一些但不是所有的 .tex 文件都有参考书目。带有参考书目的 .tex 文件将有条件地使用 bibtex 工具生成 .bbl 文件，以在最终 .pdf 文件中构建参考。这是必需的，因为如果 bibtex 没有找到文本中引用的参考书目，它将返回错误代码并中止构建过程。下面是生成文件的建议解决方案，它不起作用，因为 ifneq 没有​​评估 FILE_BIBS 的值。

Makefile（注意：四个空格应该用制表符代替，否则解释器将无法正常工作）

SOURCES:=$(wildcard $(SRC_DIR)*.tex)
BIBS:=$(wildcard $(SRC_DIR)*.bib)
OUTPUT:=$(patsubst %.tex, %.pdf, $(SOURCES))

.PHONY: all
all: $(OUTPUT) 

# Build procedure for all .tex files
%.pdf: %.tex $(BIBS) 
    pdflatex $(patsubst %.tex, %, $<) > /dev/null
    # Scan the current .tex file for the phrase \bibliography and put the text
    # into a variable called FILE_BIBS, if there is no bibliography phrase in 
    # the file, FILE_BIBS will be empty
    $(eval FILE_BIBS=$(shell grep -m 1 '^[[:space:]]*\\bibliography[[:space:]]*{' $< | sed 's/\\//g' | sed 's/{//g' | sed 's/}//g'))
    echo $(FILE_BIBS)
    # If there are .bib files in the project 
ifneq ($(BIBS),)
    echo "there are bibs FILE_BIBS: $(FILE_BIBS)"
    # See if FILE_BIBS is not empty (the file uses a bibliography)
ifneq ($(FILE_BIBS),)
    # This should print out for outline.tex and not for outline2.tex
    # This does not print out in either case
    echo "file has bib"
    bibtex $(patsubst %.tex, %, $<) > /dev/null
    pdflatex $(patsubst %.tex, %, $<) > /dev/null
endif
endif
    pdflatex $(patsubst %.tex, %, $<) > /dev/null

.PHONY: clean
clean:
    -rm -f *.pdf *.log *.out *.aux *.dvi *.blg *.bbl

我们希望在构建大纲时看到 bibtex 调用，但我们没有。这表明第二个 ifneq 工作不正常。

Makefile 不起作用，因为第二个ifneq不起作用，当FILE_BIBS非空时评估 true。建议应允许用户通过运行在文件夹中构建所有 .tex 文件，make建议解决方案之外的新解决方案应仅使用命令行interface、make、pdftex、bibtex 和 Unix/Linux 环境中的标准工具，例如 awk、sed、grep。
