wxWidgets Version 2.9 for OpenCPN (Experimental)

[bdbcat]

Hello source builders!

Here are the steps needed to build opencpn for wxWidgets 2.9.1.

1. Get wxWidgets 2.9.1 source tarball from wxwidgets.org
2. Build wxWidgets.

I build test versions of wxWidgets in subdirectories, and the use wx-config to link to the built libraries without "installing" the libraries and possibly corrupting my basic setup.

So, in the directory
{whatever}/wxWidgets-2.9.1/build_gtk_debug

I used the configure line as follows:

../configure --enable-gtk --with-debug_flag --with-debug_info --enable-debug --with-libjpeg LDFLAGS=-rdynamic --without-subdirs --prefix=/usr --enable-graphics_ctx --enable-aui

Then make, but DO NOT install.

3. Build OpenCPN, using the 2.9.1 includes and libraries.
a. In your opencpn build directory, delete the cache file CMakeCache.txt
b. Run cmake like this:
cmake -D wxWidgets_CONFIG_EXECUTABLE:FILEPATH={whatever}/wxWidgets-2.9.1/build_gtk_debug/wx-config ..

Please note the ".." at the end of the last line.

c. The make, sudo make install, and you are ready to go.
There will be some warning messages shown during the "make" step. I am ignoring them for now.


I consider wxWidgets 2.9 support for opencpn to be preliminary at this point. For one thing, it seems that the CMake modules necessary to automatically find an installed build of 2.9.1 are faulty. Thus the forced wx-config method used above.
So this is all experimental at this point, and I welcome plus or minus feedback as we work through this migration process.

Thanks, and good luck
Dave

Hi Dave

Build 1026 with vs10 and wxWidgets 2.9.1 builds fine on Vista. DIBSections were commented out.

Everything seems to work except the Dashboard plugin which does not show any valid selections in the Add menu.

Outstanding!!!

Chuck....

Thanks for trying this out. I knew that Dashboard PlugIn was not working, but turned a blind eye so far.

DIBSections commented out? Where, please? Who complains?

Really, the immediate goal is for the Mac build to now proceed further, and catch up with the rest of the group.....

Thanks
Dave

Dave,
I didn't look at it any close, but the build against wx 2.9.1 / VS 2008 fails on

ocpnMemDC::SelectObject cannot see m_oldBitmap and m_selectedBitmap.

wxMemoryDC has been changed to hide those objects.

Oh dear. I pulled a slight-of-hand trick on this class to boost performance. It always comes back to bite.

Fortunately, now, (3 years later), almost everyone has fast machines available to run on, so we can probably revert to squeaky clean portability. I started this project with 300 Mhz K-6......

Thanks

There were no problems building on Ubuntu 10.4, following your instructions. As mentioned before, there is problems with the dashboard plugin. I shows up as an empty box.
When leaving the plugin tab an assertion error comes up.

Hi!
I´m trying to build OpenCPN (using wx 2.9.1 and Visual C++ 2008) and getting these errors too, plus those errors below.
Can anyone help me?

Thanks!

Elias,
to be honest since then I tried just once to build wxWidgets SVN trunk and went away as soon as it failed. Any particular reason to try? 2.9.1 is way too buggy to use and I really had no time to go with the trunk lately. Will probably have another look at it after OpenCPN 2.5 is out, but until then I really suggest you to stick with wx 2.8 which should not give you problems if you follow the build instructions at Compiling - Windows | Official OpenCPN Homepage (and especially pay attention not to mix ANSI and Unicode stuff).
