如何在MAKE中获得更好的错误消息？

标签： c++ debugging makefile php-extension

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: In function ‘void googleset_free_storage(void*)’:
可以看出，除了向我显示有错误的函数的入口点之外，它不再给我数据。是否有标志或其他方式来获取正确的错误消息？

MakeFile - ＆gt;我知道它很大......

2 个答案:

答案 0 :(得分：0)

您必须检查Makefile及其包含的所有规则文件。找到将.cpp编译为.o的规则，看看它在编译输出上进行了哪种过滤。如果它故意限制编译器的输出以使正常编译更简洁，那么它可能会设置一个标志来覆盖它。 Linux内核（以及许多相关的Makefile）为此目的使用QUIET标志，因此您可以make QUIET=''禁用简洁输出并查看所有内容。

如果构建规则隐藏错误，则可能存在错误。如果你能找到它并将其添加到你的问题，有人可能知道如何解决它。

答案 1 :(得分：0)

您引用的行不是真正的错误消息。这只是两条线中的第一条。以下行包含非常有趣的内容。

只有在极少数情况下不是第二行才应该担心。因为那时有人包装了编译器来抑制它的一些错误信息。
