需要将一个在上层定义的变量传递给子make,应该在上层Makefile中使用指示符“export”对此变量进行声明 export VARIABLE… 1. 当不希望将一个变量传递给子make时,可以使用指示符“unexport”来声明这个变量: unexport VARIABLE… 9. 同时使用“define”定义的一组命令称为一个命令包。定义一个命令包的语法以“define...
函数功能: 函数“ origin”查询参数“ VARIABLE”(一个变量名)的出处。 $(error TEXT…) 函数功能: 产生致命错误,并提示“ TEXT…”信息给用户,并退出 make 的执行。 $(warning TEXT…) 函数功能: 函数“ warning”类似于函数“ error”,区别在于它不会导致致命错 误( make 不退出),而只是提示“ TEXT…”...
在bash中,我可以创建一个临时文件并将文本导入其中,如下所示: temp_file=$(mktemp) echo "text goes into file" > ${temp_file} cat ${temp_file} rm ${temp_file} 运行时输出(如预期的那样): text goes into file 在makefile中使用相同的代码时,我得到以下输出: makefile: test: temp_file=$(mktem...
在文件Makefile.am a中,我使用了类似这样的内容: PATH := $(PWD)/.tools/bin:$(PATH) 运行configure.ac时,我收到以下错误: Makefile.am:3: warning: ':='-style assignments are not portable 我使用赋值运算符=会导致递归问题。所以我想知道如何在Makefile.am中适配PATH变量而不出现这个问题? 浏览1提...

This code is supposed to locate all the header files and put them in a variable (sort of like the wildcard macro in GNU Make). But I get the "Access is denied" error before the !error above fires and the named "header" file does not exist on disk afterward. In fact, with subtle...
