我试图通过malloc(),realloc()释放()所有分配的内存,但valgrind说这是一个内存泄漏.

代码:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


int main(int argc, char *argv[]) {

    int lines_allocated = 128;
    int max_line_len = 50;

    FILE *fp;

    /* File allocate lines of text */
    char **array = (char **)malloc(sizeof(char*)*lines_allocated);
    if (array==NULL) {
        fprintf(stderr,"Out of memory (1).\n");
        exit(1);
    }

    FILE *file = fopen("file.txt", "r");
    if (file == NULL) {
        fprintf(stderr,"Error opening file.\n");
        exit(2);
    }

    int il;
    for (il = 0; 1; il++) {
        int j;

        /* Have we gone over our line allocation? */ …

我正在使用Ubuntu Server 14.04.我需要使用./configure --enable-unicode = ucs4选项来创建我的新django项目python.我用ucs4重新安装了python.

现在,当我试图运行scrapy spider时,我收到如下错误:

ImportError: /usr/local/lib/python2.7/site-packages/lxml-3.4.2-py2.7-linux-x86_64.egg/lxml/etree.so: undefined symbol: PyUnicodeUCS2_DecodeLatin1

然后我试图再次重新安装python但出现错误:

Compiling /usr/local/lib/python2.7/zipfile.py ...
make: *** [libinstall] Error 1

然后我试图重新安装libxml,但也有错误:

/usr/bin/ld: /usr/local/lib/python2.7/config/libpython2.7.a(abstract.o): relocation R_X86_64_32S against `_Py_NotImplementedStruct' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/python2.7/config/libpython2.7.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

Scrapy重新安装没有帮助.

请帮忙!

在C中将变量插入指针数组(插入第二维)的最有效方法是什么？像这样:

    char * get_time(void)
    {
         time_t rawtime;
         struct tm * ptm;
         time (&rawtime);
         ptm = gmtime ( &rawtime );
         ptm->tm_hour = ptm->tm_hour - 4;
         return asctime(ptm);
    }

    char *some_array[] = {
        "some" get_time() "string",
        "some string"
    }
