Compile problem

[SA7BNT]

Hallo, getting this fail when i´m trying to compile with STM32_USB_HOST

Thats my Config.h

if !defined(CONFIG_H)

define CONFIG_H

define MMDVM_HS_DUAL_HAT_REV10

define ENABLE_ADF7021

define DUPLEX

define ADF7021_14_7456

define STM32_USB_HOST

define SEND_RSSI_DATA

define SERIAL_REPEATER

And here is the last output where the fail comes

/usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/bin/ld: warning: /usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/lib/armv7-m/libstdc++_nano.a(new_opv.o) uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail /usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/bin/ld: warning: /usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/lib/armv7-m/libstdc++_nano.a(new_op.o) uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail /usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/bin/ld: warning: /usr/lib/gcc/arm-none-eabi/5.4.1/../../../arm-none-eabi/lib/armv7-m/libstdc++_nano.a(new_handler.o) uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail obj_f1/SerialSTM.o: In function CSerialPort::beginInt(unsigned char, int)': SerialSTM.cpp:(.text._ZN11CSerialPort8beginIntEhi+0x18): undefined reference tousbserial' SerialSTM.cpp:(.text._ZN11CSerialPort8beginIntEhi+0xc): undefined reference to USBSerial::begin()' obj_f1/SerialSTM.o: In functionCSerialPort::availableInt(unsigned char)': SerialSTM.cpp:(.text._ZN11CSerialPort12availableIntEh+0x20): undefined reference to usbserial' SerialSTM.cpp:(.text._ZN11CSerialPort12availableIntEh+0x16): undefined reference toUSBSerial::available()' obj_f1/SerialSTM.o: In function CSerialPort::readInt(unsigned char)': SerialSTM.cpp:(.text._ZN11CSerialPort7readIntEh+0x14): undefined reference toUSBSerial::read()' SerialSTM.cpp:(.text._ZN11CSerialPort7readIntEh+0x20): undefined reference to usbserial' obj_f1/SerialSTM.o: In functionCSerialPort::writeInt(unsigned char, unsigned char const, unsigned short, bool)': SerialSTM.cpp:(.text._ZN11CSerialPort8writeIntEhPKhtb+0x18): undefined reference to `USBSerial::write(unsigned char const, unsigned long)' SerialSTM.cpp:(.text._ZN11CSerialPort8writeIntEhPKhtb+0x3c): undefined reference to usbserial' SerialSTM.cpp:(.text._ZN11CSerialPort8writeIntEhPKhtb+0x24): undefined reference toUSBSerial::flush()' collect2: error: ld returned 1 exit status Makefile:290: recipe for target 'bin/mmdvm_f1.elf' failed make: *** [bin/mmdvm_f1.elf] Error 1

Something i´m doing wrong?? Trying to compile for USB use instead of GPIO 73 SA7BNT

Yes, you need to compile with bootloader support if you want to use USB: make bl

Works fine thanks for fast support.
