[RESOLVED] #include-ing wxWidgets

[elarsen7823]

So I recently installed and compiled wxWidgets, and since this is the first time I've done such a thing, I'm not sure how to successfully #include .h or .hpp files from the library.

Specifically, I'm trying to #include "wx/wx.h"

The source code I'm attempting to compile is here: http://www.wxwidgets.org/docs/tutorials/hworld.txt

Also, I have to admit to being self-taught, and don't have much knowledge of how a compiler works. If anybody could be so kind, I'd be very thankful for an article or something to give me a good understanding of compilers. I'd like to learn about the entire compilation process and pre-compiler processes. And I've heard about (and used, when I compiled wxWidgets) makefiles. I'd also like to learn how to create and use them.

If you need to know, I'm using MinGW.

Thank you in advance.

Hi elarsen7823, welcome to CodeGuru!

Are you using a makefile to compile your program right now? If not, what is your IDE?

If you're using a makefile, you need to tell the compiler where to look for the wx/wx.h file. This is done by adding an option "-I path" to the g++ command line, where "path" is the parent folder of the wx folder that contains wx.h.

So if your makefile looks something like this right now:

hworld.exe : hworld.cpp
        g++ -o hworld.exe hworld.cpp

you need to change it to something like this:

hworld.exe : hworld.cpp
        g++ -o hworld.exe -I C:\path\to\wxwidgets\include hworld.cpp

where the wx.h file is located at C:\path\to\wxwidgets\include\wx\wx.h

You will undoubtedly need to add other options as well, such as "-L path" for where to find the wxWidgets library files you need to link to, "path" being something like C:\path\to\wxwidgets\lib.

If you're still having problems, please post some details (e.g. the exact error you're getting when you call "make").

Hey HighCommander. Thanks for the response and sorry for the time it took me to reply.

I'm not using a makefile for this program, and I'm not using an IDE. I have no idea how to create a makefile, and I'm just using gedit and MinGW g++.

Anyway, I added the -I and -L path flags and it sort of worked. The compiler is now able to find wx\wx.h, but it threw me a bunch of other errors from all over the place. I tracked those down to a filename mistake and fixed it, and now I'm getting only one error. That is

g++ -o Hellowx.exe -I C:\wxWidgets-2.8.10\include -L path C:\wxWidgets-2.8.10\lib Hellowx.cpp

In file included from C:\wxWidgets-2.8.10\include\wx\platform.h : 293,
                        from C:\wxWidgets-2.8.10\include\wx\defs.h : 21,
                        from C:\wxWidgets-2.8.10\include\wx\wx.h : 15,
                        from Hellowx.cpp : 1 :
C:\wxWidgets-2.8.10\include\wx\chkconf.h:1817:9: #error "wxClipboard requires wxDataObject"

chkconf.h is a header that, as the name implies, checks the configuration of something (I'm assuming the compiler?) during the precompiler phase. The block of code being referred to is:

#if wxUSE_CLIPBOARD && !wxUSE_DATAOBJ

#   ifdef wxABORT_ON_CONFIG_ERROR

#       error "wxClipboard requires wxDataObject"

#   else

#       undef wxUSE_DATAOBJ

#       define wxUSE_DATAOBJ 1

#   endif

#endif /* wxUSE_CLIPBOARD */

Which means that the

#ifdef wxUSE_CLIPBOARD && !wxUSE_DATAOBJ

and the

 #ifdef wxABORT_ON_CONFIG_ERROR

statements are both evaluating positive. Is there some way to fix this? And what does the code really mean? I can only assume that my (something) is missing the definition for wxUSE_DATAOBJ.


Also, I'd still like to know if there are any good articles or papers or something dealing with compilers and makefiles. I know very little about either.

[HighCommander4]

Don't bother to try and understand the contents of files like chkconf.h - whatever went wrong in chkconf.h is the immediate cause of your problem, not the real cause, and "fixing" the immediate cause will almost certainly not fix the real cause.

The real cause of your problem is that you're not building your program with the proper compiler options - you need a few more options than what you have right now.

You said you've compiled and installed wxWidgets. I'm assuming you used either MSYS or cygwin to do this.

Open up your MSYS (or cygwin) shell and navigate to the directory where wxWidgets was compiled. There should be a shell script there called "wx-config". Run it with the parameter --cppflags, like this:

./wx-config --cppflags

The output of that is all the compiler options you need to use. Note that the file paths are in Unix format, so if you're building from the Windows command prompt you need to change them to Windows format (if you're building from MSYS/cygwin then leave them as is).

You will also need to do

./wx-config --libs

which gives you all the options necessary for linking.

With regards to makefiles, even if you know nothing about makefiles you should have a very basic one like this:

Hellowx.exe : Hellowx.cpp
        [insert your g++ command line here]

Put those lines in a file called "makefile" in your project folder. Note that before the g++ command line on the second line, there is a tab, not spaces (it matters for makefiles).

Then you can just call "make" to compile your program instead of typing out the whole g++ command line (which will be long with all the required options).

Then as your learn more about makefiles over time (read some online tutorials, I don't know of a good one off hand, just google them), you can make your makefile more sophisticated.

[elarsen7823]

Okay, I originally had compiled it using the makefiles with MinGW by itself, without MSYS. So I uninstalled wxWidgets and reinstalled it and built it with MSYS and the configure script. Then I ran the wx-config script with --cppflags and --libs and put those in a g++ command line in my makefile:

Hellowx.exe : Hellowx.cpp
	g++ -o Hellowx.exe -I/c/wxWidgets-2.8.10/build-debug/lib/wx/include/msw-ansi-debug-static-2.8 -I/c/wxWidgets-2.8.10/include -I/c/wxWidgets-2.8.10/contrib/include -D__WXDEBUG__ -D__WXMSW__ -L/c/wxWidgets-2.8.10/build-debug/lib  -mthreads  -Wl,--subsystem,windows -mwindows /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_richtext-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_aui-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_xrc-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_qa-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_html-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_adv-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_mswd_core-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_based_xml-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_based_net-2.8.a /c/wxWidgets-2.8.10/build-debug/lib/libwx_based-2.8.a -lwxregexd-2.8 -lwxexpatd-2.8 -lwxtiffd-2.8 -lwxjpegd-2.8 -lwxpngd-2.8 -lwxzlibd-2.8 -lrpcrt4 -loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32 -lcomctl32 -lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32 Hellowx.cpp

Like so. When I ran it though, I got about a million errors:

And so on for about 30000 characters. The tail end of it was:

collect2: ld returned 1 exit status
make: *** [Hellowx.exe] Error 1

I don't think this is ever going to work.

Hmm... that's strange.

You definitely have the libraries that include those missing symbols (e.g. the wxAppConsole stuff is in libwx_based-2.8.a), and g++ is definitely finding the libraries at the paths you gave it (otherwise it would complain that it doesn't).

My only suggestion is to try tweaking the order of things in your command line. I remember having some strange errors in the past that got resolved my changing around the order of things in the command line.

The makefile for the wxWidgets program that I'm developing has this order:

g++ [all options except libraries] -o [output file] [source files] [libraries]

where libraries are all the .a files and all the options starting with -l.

If changing your command line to match that order doesn't work, I'm out of ideas - try asking for helping in the wxWidgets forums or the wxWidgets mailing list.

The error list got significantly shorter. New makefile:

Any more suggestions? If not, I'll just play around with the order of my command line.

[HighCommander4]

where libraries are all the .a files and all the options starting with -l.

You didn't put the -l options at the end.

[elarsen7823]

Oops, my bad.

It's working now. Thanks.
