CMake and Other Cross-Platform Issues

[bdbcat]

Hello....

We are going to try to move away from the gnu automake/conf tools and over to cmake as our primary build configurator.

I have committed to CVS a working version of CMakeLists.txt and supporting files. Thanks so much to sethdart for his pioneering work here.

Have a look at this thread/post for more info on the operation of cmake.

My experiences:
linux: cmake 2.8.1 was fiddly to install, best approach was to use the "bootstrap" method. Running cmake and resulting build on Ubuntu was flawless.

Windows: installing cmake 2.8.1 is trivial; download the Windows installer .exe and it just works fine. Running cmake and building in VS2005 was a little fussy. The wxWidgets libraries need to have been built with the same runtime library model as is specified in the opencpn VS project built by cmake. I setup the cmake source to use /MD(release) or /MDd(debug) for the runtime library. YMMV.

Comments from cmake mavens encouraged. This is my first major project experience with it. I'm sure the script will need tweaking....

Comments Welcome

Dave,

Can not find VERSION.cmake it seems to be missing.

CMake Error at CMakeLists.txt:30 (INCLUDE): include could not find load file:
C:/devmnt/opencpn/VERSION.cmake

Thanks

Dave,

Cmake seems to work. It completed successfully. Did a build in VC and that also worked. How can I be sure that Cmake is working correctly,

I use the Ubuntu package with great success, just sudo apt-get install cmake

Started to get working, cdash site for OpenCPN.

CDash - OpenCPN

Every five minutes the cvs is checked and if a file is changed a build will be done on my Ubuntu 10.04-x86 machine. I wil set up the 64 bit version soonish and a instruktiv how to run your own build server.

Thanks for the input.
I run Ubuntu 8.04. If I do apt-get on cmake, I get Version 2.4.something.

README for 2.8.1 says that 2.4 cmake should configure and make 2.8.1 in-situ. Didn't work for me, due to confusion over /usr and /usr/local.

So, I killed all of 2.4, and did the bootstrap. Worked fine.

I think the cmake files are 2.6 safe, i think that came in 9.04 to ubuntu. I have not yet tested on 2.6 cmake thou.

Looks like gettext is missing, I was sure that was supposed to be optional.

GetText for Windows

Holds a windows port, The path may have to be specified. Not all familiar with the currect version of the cmake files.

Read this post http://www.cruisersforum.com/forums/...tml#post437991
A bit down you'll find links to "gettext" for windows.
Your error messages indicates that you probably don't have gettext installed.

PS It wasn't me putting the smiley in the upper left corner......this is serious business! (can't get rid of the thing).

Guy's,

Thanks for the help. I think that "GETTEXT_MSGFMT_EXECUTABLE-NOTFOUND" is a script. Don't see it in CVS. Will wait for Dave's input on how he wants to resolve this.

Thanks again,

Paul

OK, got this sorted out. The cmake script did not gracefully handle the case where gettext package is not available. Fixed in CVS.

Please note that if you have no gettext in Windows, then of course the application messages will all be in English. But it should run sensibly.

Also a note on cmake: Don't forget to "delete the cmake cache" when you add dependent packages like gettext. cmake does not automatically scan for changes in this kind system utility with each run.

Thanks, and good luck

Dave,

I added gettext after the first time I did a build. Didn't rerun Cmake after adding gettext. The build now works. A small point -- VC asked for the location of opencpn.exe when starting debugging the first time. It would nice for the new tester if Cmake could tell VC where the executable is located.

Thanks,

Paul

Dave,

A quick note about using Cmake on XP. It works!

I was able to updated to 526a with no problems. Used TortoiseCVS to update the OpenCPN files. Ran Cmake to update the VC project files. Built the debug version of 526a using VC. Have started testing using the VC debugger. So far everything is working great.

Here is a list of the software that needed to be installed:
1) MSVC free C++ compiler - Download details: Visual Studio 2008 Express Editions with SP1
2) TortoiseCVS: Download
3) GetText for Windows
4) Cmake for Windows - http://www.cmake.org/cmake/resources/software.html

Thank you for your hard work and help,

Paul

Built the debug version of 526a using VC. Have started testing using
the VC debugger.

Paul,

Are you able to compile for release? I'm able to do the exact same thing, running VS 2010 in debug. I'm not able to compile in release yet. A VSProject file like in the build\msw directory compiles in debug as well in release
