I'm currently porting some windows code and trying to make it available for use in Ubuntu. The project was originally compiled in VC++ without any issues. Also I should note that this only needs to work in Ubuntu, but more platform independent ideas are certainly welcome.
Most of the code is easy to port as it is mostly a numerical simulation project with few OS specific parts. There is no UNICODE used in the ported version and there is not going to be any need to support this.
I'd like to know what the best practices are when trying to get this code to compile with GCC, in particular:
What is considered to be the best replacement for: __int64, _tmain and _TCHAR* ?
Thanks!
For the 64-bit:
#include <inttypes.h>
typedef int64_t __int64;
As for the TCHAR problem. I actually find TCHARs rather useful so I have a file with all the _t functions I use in it.
e.g
#ifdef UNICODE
#define _tcslen wcslen
#define _tcscpy wcscpy
#define _tcscpy_s wcscpy_s
#define _tcsncpy wcsncpy
#define _tcsncpy_s wcsncpy_s
#define _tcscat wcscat
#define _tcscat_s wcscat_s
#define _tcsupr wcsupr
#define _tcsupr_s wcsupr_s
#define _tcslwr wcslwr
#define _tcslwr_s wcslwr_s
#define _stprintf_s swprintf_s
#define _stprintf swprintf
#define _tprintf wprintf
#define _vstprintf_s vswprintf_s
#define _vstprintf vswprintf
#define _tscanf wscanf
#define TCHAR wchar_t
#else
#define _tcslen strlen
#define _tcscpy strcpy
#define _tcscpy_s strcpy_s
#define _tcsncpy strncpy
#define _tcsncpy_s strncpy_s
#define _tcscat strcat
#define _tcscat_s strcat_s
#define _tcsupr strupr
#define _tcsupr_s strupr_s
#define _tcslwr strlwr
#define _tcslwr_s strlwr_s
#define _stprintf_s sprintf_s
#define _stprintf sprintf
#define _tprintf printf
#define _vstprintf_s vsprintf_s
#define _vstprintf vsprintf
#define _tscanf scanf
#define TCHAR char
#endif
as for the _s functions basically ... I implemented them. It takes about an hour of coding to do but it makes porting projects to other platforms or compilers IMMENSELY easier.
