If I do not use any espconn functions then project compiles without errors, but if there are some espconn functions in the code the mentioned error occurs.
For example, I've tested the issue on a simple code:
Code:
#include "esp_common.h"
void upgrade_recon_cb(void *arg, sint8 errType)
{
printf("Connection error: ");
}
void user_init(void)
{
struct espconn *conn;
espconn_regist_reconcb(conn, upgrade_recon_cb);
}
void user_rf_cal_sector_set(void)
{
}
and compilation finished with the errors:
Code:
c:/Espressif/ESP8266_RTOS_SDK_1.5/lib\libespconn.a(espconn_buf.o):(.text.ringbuf_findchr+0x8): undefined reference to `memchr'

collect2.exe: error: ld returned 1 exit status
C:/Espressif/examples/esp_rtos_sdk_example_2/Makefile:198: recipe for target 'build/app.out' failedP.S. I tried other espconn functions instead of espconn_regist_reconcb but the result was the same.
I'm confused with the issue because it is hard to believe that such an error is there in new SDK
Does anybody use RTOS_SDK_1.5 ?
