我正在尝试将.cc文件编译为mex,并且我在Matlab中使用了mex文件名命令。我的编译器是 [1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2012b\sys\lcc 。
但是,存在一些错误:
lcc preprocessor error: learn.cc:5 Could not find include file <sys/time.h>
Error learn.cc: 70 illegal statement termination
Error learn.cc: 70 skipping `int'
Error learn.cc: 70 undeclared identifier `alen'

Error learn.cc: 106 missing identifier
Error learn.cc: 106 too many errors
我想第一个错误的原因是 sys 文件夹中没有 time.h 文件。取而代之的是timeb.h文件。但我不知道以下错误的原因。
以下是一些相关代码:
line 70 int alen = **((int **)a);
line 71 int blen = **((int **)b);
line 86-93 struct data {
collapsed *x;
int num;
int numblocks;
int *blocksizes;
float *regmult;
float *learnmult;
};
line 96-100 void seed_time() {
struct timeval tp;
check(gettimeofday(&tp, NULL) == 0);
srand48((long)tp.tv_usec);
}
line 102 static inline double min(double x, double y) { return (x <= y ? x : y); }
line 103 static inline double max(double x, double y) { return (x <= y ? y : x); }
谁能给我一个提示?
据我所知,第 70,71 行没有任何问题。a,b 整数双精度数组是否声明和分配如下内容:
int ** a = malloc(4 * sizeof(int*) );
for (int var = 0; var < 4; ++var) {
a[var] = malloc(3*sizeof(int));
}
?
您确定 sys/time.h 文件可以用 sys/timeb.h 文件替换吗?你试过吗?sys/time.h 看起来像一个漂亮的 linux/unix 特定文件。你确定 sys/文件夹引用你的 matlab sys 目录 (C:\PROGRA~1\MATLAB\R2012b\sys\lcc)?
通常,看起来您正在尝试在Windows计算机上编译linux .mex文件。例如gettimeofday是一个Linux纯调用(根据这个答案):相当于 Windows 的 gettimeday()
