Automake Flex输出命名 [英] Automake flex output naming

问题描述

例如，如果使用

foo_SOURCES = bar.l

foo_SOURCES = bar.l

然后，自动制作通过弹性文件 bar.c 生成.但是，如果我提供前缀 AM_LFLAGS = -Psome_prefix ，则会生成 lex.some_prefix.c ，其他人不知道编译规则，因此它失败并显示 bar.c:没有这样的文件或目录.我的错误在哪里，我该如何解决?我真的需要前缀.

then, automake generates via flex file bar.c. But, if I provide prefix AM_LFLAGS=-Psome_prefix, it generates lex.some_prefix.c, which is not known by other compilation rules, so it fails with bar.c: No such file or directory. Where is my mistake and how can I work around it? I really need prefix.

推荐答案

我认为解决此问题的唯一方法是为.l->.c翻译编写自己的规则.像这样:

I think the only way around this is to write your own rule for the .l->.c translation. Something like:

x_SOURCES = lex.some_prefix.c
lex.some_prefix.c: lex.l
    ... rule here

您可能还需要进行一些调整以确保您分发.l文件.

You may also need a tweak to ensure you distribute the .l file.
