|

On Microsoft Windows, wxWidgets has a different set of makefiles for each
|
||||
compiler, because each compiler's 'make' tool is slightly different.
|
||||
Popular Windows compilers that we cater for, and the corresponding makefile
|
||||
extensions, include: Microsoft Visual C++ (.vc), Borland C++ (.bcc),
|
||||
OpenWatcom C++ (.wat) and MinGW/Cygwin (.gcc). Makefiles are provided
|

for the wxWidgets library itself, samples, demos, and utilities.

Some compilers, such as Borland C++ and Microsoft C++, support

precompiled headers. This can save a great deal of compiling time. The

recommended approach is to precompile @c "wx.h", using this

precompiled header for compiling both wxWidgets itself and any

wxWidgets applications. For Windows compilers, two dummy source files

are provided (one for normal applications and one for creating DLLs)

is that to take advantage of the facility, you often need to include

more header files than would normally be the case. This means that

changing a header file will cause more recompilations (in the case of

wxWidgets, everything needs to be recompiled since everything includes @c "wx.h" !)

wxWidgets, everything needs to be recompiled since everything includes @c "wx.h" !)
|
||||
|
||||
A related problem is that for compilers that don't have precompiled
|
||||
headers, including a lot of header files slows down compilation
|
||||
considerably. For this reason, you will find (in the common
|
||||
X and Windows parts of the library) conditional
|
||||
compilation that under Unix, includes a minimal set of headers;
|
||||
and when using Visual C++, includes @c wx.h. This should help provide
|
||||
the optimal compilation for each compiler, although it is
|
||||
biased towards the precompiled headers facility available
|
||||
in Microsoft C++.

When building an application which may be used under different
|
||||
environments, one difficulty is coping with documents which may be
|
||||
moved to different directories on other machines. Saving a file which
|
||||
has pointers to full pathnames is going to be inherently unportable.

|

|

One approach is to store filenames on their own, with no directory
|
||||
information. The application then searches into a list of standard
|
||||
paths (platform-specific) through the use of wxStandardPaths.

Eventually you may want to use also the wxPathList class.

Nowadays the limitations of DOS 8+3 filenames doesn't apply anymore.
|
||||
Most modern operating systems allow at least 255 characters in the filename;
|
||||
the exact maximum length, as well as the characters allowed in the filenames,
|
||||
are OS-specific so you should try to avoid extremely long (> 255 chars) filenames
|
||||
and/or filenames with non-ANSI characters.

Another thing you need to keep in mind is that all Windows operating systems
|
||||
are case-insensitive, while Unix operating systems (Linux, Mac, etc) are
|
||||
case-sensitive.

Also, for text files, different OSes use different End Of Lines (EOL).
|
||||
Windows uses CR+LF convention, Linux uses LF only, Mac CR only.

|

|

The wxTextFile, wxTextInputStream, wxTextOutputStream classes help to abstract
|
||||
from these differences.
|
||||
Of course, there are also 3rd party utilities such as @c dos2unix and @c unix2dos
|
||||
which do the EOL conversions.
