Compiling error for ESP8266 with I2C-libary - arduino

Question

i want to upload a Script to read out a Lightsensor i have bought. The Sensor is a Grove - Sunlightsensor and the libary for it can be found on GitHub.
The Board i am going to use is a WeMos D1 Mini using a ESP8266, but since many Pins are taken i want to use GPIO2 as SDA and 13 as SCL which can be achieved with: Wire.begin(2,13);
But the Pins are not relavant for compiling.
I want to try the example-script found in the libary from the producer:
#include "Si115X.h"
Si115X si1151;
/**
* Setup for configuration
*/
void setup()
{
uint8_t conf[4];
Wire.begin(2,13);
Serial.begin(115200);
if (!si1151.Begin())
Serial.println("Si1151 is not ready!");
else
Serial.println("Si1151 is ready!");
}
/**
* Loops and reads data from registers
*/
void loop()
{
Serial.print("IR: ");
Serial.println(si1151.ReadHalfWord());
Serial.print("VISIBLE: ");
Serial.println(si1151.ReadHalfWord_VISIBLE());
Serial.print("UV: ");
Serial.println(si1151.ReadHalfWord_UV());
delay(100);
}
But i get the following error massage:

collect2.exe: error: ld returned 1 exit status

Compilation error: exit status 1
I already tried using a different compilerversion (2.7.4) but the same error accured.
I might be wrong and not expirienced but the error output seems that something is messed up in the libary itselfe?
Thanks for any help. If further information is needed i am happy to give it to you.
