The example for LZ4 works fine, however I want to use the frame format and not block format.
Therefore I added #include "lz4frame.h" to my main.c and tried to use LZ4F_compressFrame().
But the compiler prints undefined reference to `LZ4F_compressFrame'
The prj.conf contains CONFIG_LZ4=y
Small update, I got it running using the CMakeLists directly, however it crashed at LZ4F_compressFrame(), more specific in the MEM_INIT() function:
This is my code:
static const unsigned char src[24] = {0x46, 0x3d, 0xff, 0xff, 0x7b, 0x62, 0xf3, 0xb0, 0x7f, 0xdc, 0xff, 0x87,
0x8f, 0x63, 0x7f, 0x7e, 0x9e, 0x67, 0xbe, 0x13, 0x5c, 0xfe, 0xc0, 0xff};
const int max_dst_size = LZ4F_compressFrameBound(sizeof(src), NULL) * 2;
char *compressed_data = malloc((size_t)max_dst_size);
if (compressed_data == NULL)
{
printk("Failed to allocate memory for compressed data\n");
return 0;
}
const int compressed_data_size = LZ4F_compressFrame(compressed_data, max_dst_size, src, sizeof(src), NULL);
if (compressed_data_size <= 0)
{
printk("Failed to compress the data\n");
return 0;
}
printk("Original Data size: %d\n", sizeof(src));
printk("Compressed Data size : %d\n", compressed_data_size);
