如何在 MAKE 中获得更好的错误消息？

Question

我在 CPP 代码上运行 make 命令。我收到如下错误消息： /home/itaymoav/dev/phpext/sitel/build/entities.cpp：在函数“void googleset_free_storage(void*)”中：
可以看出，除了向我显示有错误的函数的入口点之外，它没有给我更多数据。是否有标志或其他方式来获取正确的错误消息？

生成文件->我知道它很大...

Answer 1

您必须检查您的Makefile 及其包含的所有规则文件。找到将 .cpp 编译为 .o 的规则，并查看它对编译输出执行何种类型的过滤。如果它有意限制编译器的输出以使正常编译不那么冗长，它可能会有一个您可以设置的标志来覆盖它。 Linux 内核（以及许多相关的 Makefile）使用 QUIET 标志来实现此目的，因此您可以执行 make QUIET='' 来禁用简洁输出并查看所有内容。

如果构建规则隐藏了错误，则其中可能存在错误。如果您能找到它并将其添加到您的问题中，有人可能知道如何解决它。

Answer 2

您引用的行不是真正的错误消息。这只是两行中的第一行。下面一行包含了真正有趣的东西。

只有在极少数情况下，没有第二行，您才应该担心。因为后来有人包装了编译器来抑制它的一些错误消息。
