Compile CodeBlocks by Cygwin

[PetrPetrov]

I want to build CB in Cygwin environment.

In particular I use latest x86_64 Cygwin.
I installed gcc, g++, make in Cygwin.
Also I installed x11 libraries and installed local X11 server on my Windows host.
So, many GUI X11 programs work fine in my Cygwin environment (like git gui, gitk, text editors etc.)

I want to run in the same manner CB.
First, CB requires wxWidgets.
Cygwin does not have wxWidgets from the box.
I downloaded the latest 2.8.12 version of wxWidgets sources and build it:
./configure --build=x86_64-pc-cygwin --without-msw --without-gtk --with-x11

which means that I want to build wxWidgets by using X11 libraries (instead of MSW by default).
Then I type, "make", "make install".
Here was a small compilation error, I fixed it, and wxWidgets libraries were installed successfully into my Cygwin env.

Second step is to build CB.
I downloaded "codeblocks-12.11release8629" sources.
./configure steps passed fine.

Then I type "make" and give the following error  (not just immediately after start, error becomes after some long time of compilation):

Could advise how to fix this compilation error?

./configure --build=x86_64-pc-cygwin --without-msw --without-gtk --with-x11

C::B requires wxGTK and it cannot work with wxX11, sorry.
Also I'm sure you're the first trying to build C::B inside cygwin and also I'm not sure why you want to inflict this pain to yourself:)

[PetrPetrov]

Thank you for answer.

I will try to build wxWidgets version which is based on GTK library.

Not the first, I have tried it twice. But, its been about two years since last try.

stahta01: Why? What is the benefit of running a cygwin version of C::B?

[PetrPetrov]

Now I have build wxWidgets-2.8.12 by using GTK+ 2.0 library.

Note that I used "all port" source package for wxWidgets (http://prdownloads.sourceforge.net/wxwindows/wxWidgets-2.8.12.tar.gz), wxGTK only had configuration/compilation problem.

I used
./configure --build=x86_64-pc-cygwin --with-gtk --without-msw --without-x11

line to configure wxWdigets.
After this, wxWidgets was build fine and installed successfully.
Note I was need to install additionally 'pkg-config' package for Cygwin, otherwise wxWidget configuration script did not find installed GTK 2.0 development libraries into my Cygwin.

However, I have the same error during compilation of C::B
src/wxscintilla.cpp:169:17: error: definition of static data member 'wxScintilla::ms_classInfo' of dllimport'd class
IMPLEMENT_CLASS(wxScintilla, wxControl)
src/wxscintilla.cpp:170:25: error: definition of static data member 'wxScintillaEvent::ms_classInfo' of dllimport'd class
IMPLEMENT_DYNAMIC_CLASS(wxScintillaEvent, wxCommandEvent)

[PetrPetrov]

It seems that class that causes problem is wxScintilla.
This class defines some custom wxWidget control which is used insude C::B.

Source file of this class is here:
C:\cygwin64\usr\src\codeblocks-12.11release8629\src\sdk\wxscintilla\src\wxscintilla.cpp
and header file is here:
C:\cygwin64\usr\src\codeblocks-12.11release8629\src\sdk\wxscintilla\include\wx\wxscintilla.h

Code into header file:
class WXDLLIMPEXP_SCI wxScintilla : public wxControl {
public:
..... methods

It seems that wxScintilla or its parent class should define sm_eventTable member and some other members.
Also I see that problem is related to dllimport's class. I guess that wxControl is dll-imported class (this is because it is located into another library - wxWidget).
As workaround I can try to build wxWidget as a static library.

But I guess that problem is in WXMAKINGDLL_SCI macro.

wxscintilla.cpp is being compiled with -DWXUSINGDLL symbol which means to use wxWidget library as a shared library.
Also I see (in begin of wxscintilla.h):
#ifdef WXMAKINGDLL_SCI
    #define WXDLLIMPEXP_SCI WXEXPORT
#elif defined(WXUSINGDLL_SCI) || defined(WXUSINGDLL)
    #define WXDLLIMPEXP_SCI WXIMPORT
#else // not making nor using DLL
    #define WXDLLIMPEXP_SCI
#endif
And in such a case I think that  #define WXDLLIMPEXP_SCI WXIMPORT will be used!

wxscintilla class is part of C::B, not it is not part of wxWidget library, I think.
So, it uses wrong WXDLLIMPEXP_SCI macro.

It seems that I have fixed above compilation error and build is going ahead now...

[oBFusCATed]

Patches welcome...

It seems that C::B tries to use GetToolTip() method which is absent. Missing included header file? Any ideas?

[Jenna]

The wx/tooltip.h header is included at the top of the cbauibook.cpp file.

It's most likely a wxWidgets configuration problem.

Configuring and compiling wxWidgets in a way you get all defines correctly is surely a hard way. And without good knowledge of wxWidgets (and surely C::B) it will be really hard and I doubt there will be much help from the community.
Not because nobody wants to help, but because nobody ever did it.

And I personally see no reason not to use a standard windows build.

stahta01: Why? What is the benefit of running a cygwin version of C::B?

When I was doing a lot of CB Patches; I thought building CB under CygWin would mostly test the Linux CB Build stuff.

I was also thinking of making a CB version to do better debugging of programs under CygWin;
that is the only reason I can think of to run a CygWin built CB.

It seems that wxWidgets library was configured incorrectly.
I.e. It is required that wxWidgets should be compiled with --enable-tooltips flag.
However, if I set --enable-tooltips option for ./configure script then setup.h will anyway #define wxUSE_TOOLTIPS 0 ,
i.e. something goes wrong.
I manually edited this file after configuration step to enable wxUSE_TOOLTIPS to 1:
C:\cygwin64\usr\src\wxWidgets-2.8.12\lib\wx\include\gtk2univ-ansi-release-static-2.8\wx\setup.h

Also I used static configuration to avoid problem with wxScintilla class.
My full configuration line is:
./configure --build=x86_64-pc-cygwin --without-msw --without-x11 --with-gtk --enable-tooltips --enable-monolithic --enable-dnd --disable-shared --enable-universal

[PetrPetrov]

Just have noticed from configure's log:
configure: WARNING: wxTooltip not supported yet in wxUniversal... disabled

[stahta01]

gtk2univ-ansi-release-static-2.8

I would NOT use Universal.
I might try Unicode instead of ANSI; but, you are likely right in trying ANSI because the last time I tried CygWin did NOT support Unicode.
I would NOT use static because I think CB requires wxWidgets be in a DLL.
