I put this into [PIC] as this has something to do with a breakthrough
with PICkit 2 under Linux.

I do not know much about C++ but I am having problem to build a
C++ program under different Linux distros. Ubuntu 6.06 is fine
(with g++ 3.3/3.4/4.0). Ubuntu 7.04/7.10 (with g++ 3.3/3.4/4.1)
and Arch Linux (g++ 4.2) are not fine.

This has something to do with Linux version of pk2cmd
(the console version of PICKit 2) which Jeff Post replaced Windows
HID API with libusb under Linux and wrote some replacement
functions for some Windows specific C library functions.

Under Ubuntu 6.06  the build process is fine and the resultant
program also works nicely with my limit testing on 16F/18F PICs.
This is really very nice. However I could not build it under other
Ubuntu versions and Arch.

The offending codes are in the original source code package
(written for the free Visual C++ 2005 Express Edition).
http://ww1.microchip.com/downloads/en/DeviceDoc/PICkit2_PK2CMD_SourceV1_00.zip

For example:
g++ -Wall -D_GNU_SOURCE -O2 -I/usr/local/include -DLINUX -DUSE_DETACH
-DCLAIM_USB -o cmd_app.o  -c cmd_app.cpp
In file included from PICkitFunctions.h:4,
                 from cmd_app.h:2,
                 from cmd_app.cpp:3:
DeviceData.h:15: error: extra qualification 'CDeviceData::' on member
'ClearAllData'
DeviceData.h:16: error: extra qualification 'CDeviceData::' on member

DeviceData.h:18: error: extra qualification 'CDeviceData::' on member
'ClearUserIDs'
DeviceData.h:19: error: extra qualification 'CDeviceData::' on member
'ClearEEPromMemory'

#pragma once



#define	MAX_MEM	262144

#define	MAX_EE	8192

#define	MAX_CFG	8

#define	MAX_UID	128



class CDeviceData

{

	public:

		CDeviceData(void);

		~CDeviceData(void);

		void CDeviceData::ClearAllData(unsigned int progMemSize, unsigned
short int eeMemSize, unsigned char numConfigs,

							   unsigned char  numIDs, unsigned int memBlankVal, int
eeBytes, int idBytes,

							   unsigned short int configBlank[], unsigned int OSCCALInit);

		void CDeviceData::ClearProgramMemory(unsigned int progMemSize,
unsigned int memBlankVal);

		void CDeviceData::ClearConfigWords(unsigned char numConfigs,
unsigned short int configBlank[]);

		void CDeviceData::ClearUserIDs(unsigned char numIDs, int idBytes,
unsigned int memBlankVal);

		void CDeviceData::ClearEEPromMemory(unsigned short int eeMemSize,
int eeBytes, unsigned int memBlankVal);



		unsigned int ProgramMemory[MAX_MEM];

		unsigned int EEPromMemory[MAX_EE];

		unsigned int ConfigWords[MAX_CFG];

		unsigned int UserIDs[MAX_UID];

		unsigned int OSCCAL;

		unsigned int BandGap;

};


Once I remove the so called "extra qualification" within all the header
files, I can build the program and the resultant binary is again working.

Jeff thinks this is proper C++ and he does not have the time and Linux
distros right now to debug the issues. So I will try to get the help here.

What do you think? Could I add a compiler switch to solve the problem.

CC=g++
DBG=-O2
OPTS=-Wall -D_GNU_SOURCE $(DBG)
CFLAGS=$(OPTS) -I$(LIBUSB)/include -DLINUX -DUSE_DETACH -DCLAIM_USB

Thanks in advance.
