dangerous relocation: call0: call target out of range: system_get_flash_size_map #142

Instead of compiling the source files every time, I built a static library for the esp_mqtt. A try to link the library with a user_main function stops at a point with a message

gcc version 4.8.2 (GCC) ./lib/libesp_mqtt.a(rfinit.o): In functionuser_rf_cal_sector_set': rfinit.c:(.text+0x5): dangerous relocation: call0: call target out of range: system_get_flash_size_map

Do I have to select different bin file to link to or what ? `

A couple things:

There is already the means for compiling this repo as a library (though not documented in the readme, i don't blame you for you not knowing about it). You can simply call the esp makefile with target "lib". see this commit 8cf1063d8054268a4720c0d9005fef15a9645a6d
Secondly, it would be good to see more of your compile/linker steps. Specifically your final linker command... possibly makefile snippet

I never had a problem in building the static library. Above message occurred when I tried linking the lib to an application. But the problem is gone (somehow). Thanks
