Hi,

I've realy an issue with buils a project. 
I work with Visual Studio Community 2015 and Visual Micro in the latest Build and Arduino 1.6.5.
I get the follwing error message:

Error creating .elf 

'I allready tried to reinstall Arduino IDE. Same problem.

I have a project with several libraries within the same folder as the .in0 file.

The two functions mentioned in the error message are listed here: 

void VescUartSetCurrent(float current) {
	int index = 0;
	uint8_t payload[3];

	payload[index++] = COMM_SET_CURRENT ;
	buffer_append_int16(payload, (int)(current * 1000), &index);
	PackSendPayload(payload, 3);
}

void VescUartSetCurrentBrake(float brakeCurrent) {
	int index = 0;
	uint8_t payload[3];

	payload[index++] = COMM_SET_CURRENT_BRAKE;
	buffer_append_int16(payload, (int)(brakeCurrent * 1000), &index);
	PackSendPayload(payload, 3);

} 

I've no idea how to solve this problem and get stocked in my problem!

Hi,

Just tried it also on the IDE. There I get at least an error message. Would be great to see that as well on Visual Micro.

The error message I get is

VescUart.cpp.o: In function `VescUartSetCurrent(float)':
C:\Users\AC\AppData\Local\Temp\build8358227366628126910.tmp/VescUart.cpp:196: undefined reference to `buffer_append_int16(unsigned char*, int, int*)'
VescUart.cpp.o: In function `VescUartSetCurrentBrake(float)':

collect2.exe: error: ld returned 1 exit status
Fehler beim Kompilieren.

 

But I still don't know where the error is.

Ahh, I forgot to tell you to double click the visual micro compiler messages. They take you to the correct line of code so it becomes more obvious. 

Unfortunately to get the double click to work the error message suffered and needs some additional work which will happen during the next few months.
