I meet some problem and I can't figure it out, needs some help (1MB memory):

Well... at first sight could be a "data size" problem.
Maybe your code is too big so some variables/functions cannot be linked in and so "missing" and generating a lot of errors.

Code: Select all

this problem can be resolved by two ways,
firstly，you need a bigger size flash ,
secondly,extensa compile can not support some std c function yet,such as file read/write/seek operation,so you need remove this function call from your code,or you can reconstruct them yourself.
hope these infomation can help you.
ps:find out all keywords like "seek" "open" "close" from your code
PS:hope espressif can resolve this complie issue asap,and explain why...

forgot one most important infomation,remove std c header include file from your code,such as "#include <stdio.h>"

by comment this function, compile works:

enum wsFrameType { // errors starting from 0xF0
WS_EMPTY_FRAME = 0xF0,
WS_ERROR_FRAME = 0xF1,
WS_INCOMPLETE_FRAME = 0xF2,
WS_TEXT_FRAME = 0x01,
WS_BINARY_FRAME = 0x02,
WS_PING_FRAME = 0x09,
WS_PONG_FRAME = 0x0A,
WS_OPENING_FRAME = 0xF3,
WS_CLOSING_FRAME = 0x08
};

void ICACHE_FLASH_ATTR wsMakeFrame(const uint8_t *data, size_t dataLength, uint8_t *outFrame, size_t *outLength, enum wsFrameType frameType)
{
assert(outFrame && *outLength);
assert(frameType < 0x10);
if (dataLength > 0)
assert(data);

outFrame[0] = 0x80 | frameType;

if (dataLength <= 125) {
outFrame[1] = dataLength;
*outLength = 2;
//} else if (dataLength <= 0xFFFF) {
// outFrame[1] = 126;
// uint16_t payloadLength16b = (uint16_t) dataLength; //htons(dataLength);
// memcpy(&outFrame[2], &payloadLength16b, 2);
// *outLength = 4;
} else {
//assert(dataLength <= 0xFFFF);
assert(dataLength <= 125);

// implementation for 64bit systems
//outFrame[1] = 127;
//dataLength = htonll(dataLength);
//memcpy(&outFrame[2], &dataLength, 8);
//*outLength = 10;
}
memcpy(&outFrame[*outLength], data, dataLength);
*outLength+= dataLength;
}

but after comment this function, not much left:

Fix it, I use IoT sample as a start project, after removing user_esp_platform, I have enough irom space right now. I should really be very careful ... when I add functions, thanks!
