And maintaining one building script for all platforms may be easier than synchronizing changes across different build systems. FOr example, it works nicely with SConstructs. While in some of those systems you will have to code in flags for different compiler, it will be possible to use same script everywhere. Try to use same build system on all platforms.When you have to use OS-specific calls, use conditional compilation (#ifdef WIN32, etc).Use standard functions for accessing files. For example, SDL provides types like Uint8, Qt 4 has quint32, etc. OR use types provided by cross-platform library. It is very likely that you'll need some kind of type that is guaranteed to be 4 bytes long (or something like that) - use typedef combined with conditional compilation ('#ifdef WIN32'). Do not rely on compiler-specific data types, like _int32.For example, last time I checked '%S' behaves differently on msvc and gcc in vswprintf routine. For example, sprintf may have different additional formats that are implemented differently on different platforms. (I know that it is supposed to be a bad practice, but in some scenarios this is useful) They have slightly different implementations, extensions, and different number of parameters. Be very careful if you decide to use C-style routines (like sprintf) in C++ code.Which, of course, won't be available on other platforms.

For example, MS compiler provides multiple 'safe' (like strcpy_s) versions of standard C-style routines. This more applicable to C library functions, though.

Do not use extensions to standard library (provided by compiler developer).

Do not use compiler-specific pragmas, macros and extensions.

And you should not assume that pointer is 4 bytes large (passing user data pointer into api call scenario) - it will be 8 bytes on 64 bit. Use sizeof (if you need it), or try to avoid having to use size of any type in your code. For example, on msvc sizeof(wchar_t) is 2 bytes.

Do not rely on sizes of standard types.

For example, certain versions of ms compiler have a limit on sizes of string constants, which gcc doesn't have. Even if your code is perfect, compiler might have some kind of unexpected quirk. 'microsoft compiler'), and a linux installation with g++ (or use virtual machine).

If you're doing cross-platform software for windows windows/linux, keep around mingw, visual studio express (i.e.

Keep several compilers nearby, test code regularly on target platforms.

Could you help me find a way around this? Thanks.What are the things that I should keep in mind to write portable code? But, I am still stuck as I mentioned above.

#HOW TO WRITE C CODE ON LINPROG OFFLINE#

I gave up on the offline approach and I then wrote the whole code again directly in Simulink(online approach) wishing that the problem would get resolved. I added it to code.extrinsic function and I then started getting some other error which I couldn't understand. Now, I still got into these code generation error issue every time I executed the 'ppval' function. So I let it stay in the Workspace and I was accessing it from there. Now the data structure that Matlab uses for splines couldn't be directly brought into Simulink. example x, fval, exitflag, output linprog( ) additionally returns a value exitflag that describes the exit condition, and a structure output that contains information about the optimization process. I then tried to interpolate the data using splines. x,fval linprog(), for any input arguments, returns the value of the objective function fun at the solution x: fval fx. So I wrote a code in Matlab itself and for a predefined trajectory, I got optimal values. Initially I did not want to optimize online, ie., at every time-step. Using the optimization I hope to get a few optimal torque values for my robot which I will have to apply on the robot in ADAMS and study its behavior. Moving on, I want to give you a brief summary of what I intend to do.
