Question

我正在构建一些代码，用于使用旧版本的Rowley Crossworks for ARM版本2进行正确编译。现在尝试使用Crossworks for ARM版本4编译应用程序，以下头文件会导致编译器抛出以下内容错误：

  

'UEZMemAlloc'冲突类型的冲突类型   'UEZMemRealloc'

在我看来，新的编译器现在对此感到恼火：

#define malloc(a)           UEZMemAlloc(a)
#define realloc(a, b)       UEZMemRealloc(a, b)

我正在使用的uEZ库有documentation here.似乎表明它是故意的。随着时间的推移，gcc编译器/预处理器是否变得更加挑剔？有没有办法避免这些错误？ Rowley Crossworks for ARM使用GCC。

Answer 1

解决方案是修改Config_Build.h文件，导致编译不改变某些标准C类型的类型。
