Hi I'm trying to build an mBed project on the LPCxpresso Toolchain . My target device is the LPC1768 microcontroller board. I tested the program on the online compiler and it compiles well but it's not the case on LPCXpresso. I'm having build errors on some of the classes defined in the Vodafone USB Modem library. For instance in the class below, the compiler mainly complains about the use of the member functions getc() and putc() <<code title=IUSBHostSerial.h >> /* IUSBHostSerial.h */ #ifndef IUSBHOSTSERIAL_H_ #define IUSBHOSTSERIAL_H_ /** * Generic interface to abstract 3G dongles' impl */ #include "IUSBHostSerialListener.h" class IUSBHostSerial { public: enum IrqType { RxIrq, TxIrq }; /* * Get a char from the dongle's serial interface */ virtual int getc() = 0; /* * Put a char to the dongle's serial interface */ virtual int putc(int c) = 0; /* * Read a packet from the dongle's serial interface, to be called after multiple getc() calls */ virtual int readPacket() = 0; /* * Write a packet to the dongle's serial interface, to be called after multiple putc() calls */ virtual int writePacket() = 0; /** * Check the number of bytes available. * * @returns the number of bytes available */ virtual int readable() = 0; /** * Check the free space in output. * * @returns the number of bytes available */ virtual int writeable() = 0; /** * Attach a handler to call when a packet is received / when a packet has been transmitted. * * @param pListener instance of the listener deriving from the IUSBHostSerialListener */ virtual void attach(IUSBHostSerialListener* pListener) = 0; /** * Enable or disable readable/writeable callbacks */ virtual void setupIrq(bool en, IrqType irq = RxIrq) = 0; }; #endif /* IUSBHOSTSERIAL_H_ */ <</code>> Here's the list of errors that I'm getting for the line 23: * <<error>>expected ')' before '--' token<</error>> * <<error>expected unqualified-id before '--'<</error>> and these are the errors that I'm getting for the line 28: * <<error>>'putc' declared as a virtual field<</quote>> * <<error>> macro "putc" requires 2 arguments, but only 1 given<</error>> The build is also complaining of the use of these functions in the file 'USBSerialStream.cpp'. <<code title= getc function call>> void USBSerialStream::readable() //Callback from m_serial when new data is available { while(m_serial.readable()) { m_inBuf.queue(m_serial.getc()); } m_serial.readPacket(); //Start read of next packet m_availableSphre.release(); //Force exiting the waiting state } <</code>> The following errors are obtained from line 6 of the code above: * <<error>>expected primary-expression before ')' token<</error>> * <<error>>expected unqualified-id before '(' token <</error>> <<code title= putc function call>> void USBSerialStream::writeable() //Callback from m_serial when new space is available { if(m_outBuf.isEmpty()) { m_serialTxFifoEmpty = true; } else { m_serialTxFifoEmpty = false; while(m_serial.writeable() && !m_outBuf.isEmpty()) { uint8_t c; m_outBuf.dequeue(&c); m_serial.putc((char)c); } m_serial.writePacket(); //Start packet write } if(!m_outBuf.isFull()) { m_spaceSphre.release(); //Force exiting the waiting state } } <</code>> Line 14 of the code above produces the following error: * <<error>> macro "putc" requires 2 arguments, but only 1 given<</error>> I know that there are standard C functions named putc and getc which is probably what the compiler thinks I'm intending to use instead when I'm making the function calls. That might be why it's only complaining about these two functions among all the others defined in the IUSBHostSerial class but I don't think the <stdio.h> library has been included as that's where these functions are defined. I'm also thinking that some compilation options must be set, but I don't know which ones. Basically, how do I configure the project in the same exact way that it is configured for the online compiler? Note: I'm working on a fairly old version of the VodafoneUSBModemLibrary, which I've imported from the program below. If you want to help me solve this, you just need to export this program to LPCXpresso as it already uses the library where I'm getting the errors from. <<program /users/ashleymills/code/VodafoneSMSBasics/docs/60fd177f8a6a/main_8cpp_source.html >> I would be extremely grateful if anyone can help me with this as I want to develop this program in an external envrionment.
