客户的代码期望在“通常的可疑”位置之一中找到包含文件malloc.h。在我的Mac AFAICT上，没有malloc.h，至少没有在您希望找到的任何地方，例如/usr/include，/usr/local/include或/opt/local/include。由于malloc()通常是在stdlib.h中定义的，并且由于代码无论如何都包含stdlib.h，因此我只需注释掉malloc.h的少数几个包含项就可以构建代码。我正在与gcc建立。
但是有两个问题：我的gcc是否以某种方式弄乱了？该文件应该在那里吗？另外，代码炸弹几乎立即出现段错误，但我还无法找到。这可能是使用错误的malloc()的结果吗？

malloc.h已过时，不应使用。它也包含一些非标准功能。如果要使用malloc，请添加stdlib.h。甚至C89标准都没有提到malloc.h
如果是造成您问题的原因，我不知道，但这很有可能。

下面的清单可以提供关于应该/应该在哪里找到文件的想法。不过，我无法在没有更多细节的情况下解释该段错误。我看不到它如何与malloc（）有任何关系。
