Pavel,

Thank you for your encouragement. The answer was in the above quote. I purged the entire build folder and now cmake works. I can't explain why it did not before but it must have been some cached text file(s). Again, thanks for the support.

Hi all!

In the Developer's guide - Compiling windows
Compiling - Windows | Official OpenCPN Homepage
source directories are referred to.
I find this a bit unclear.


Section 3 : Getting the OpenCPN source.

To update the code you cloned before, cd into the source directory and issue git fetch --all
Now what source directory is that ?
Is it the source tree i.e
cd OpenCPN or
cd OpenCPN/src ?

My guess is that it's
cd OpenCPN

Section 4 : Building Open CPN

Create a directory named build under the topmost source directory.

mkdir OpenCPN/build or
mkdir OpenCPN/src/build ?

My guess is that it's
mkdir OpenCPN/build

Please excuse my ignorance.

Hans...
You clone the source tree, so it's topmost directory is "OpenCPN"
Technically, if you used the other logic and did everything in "OpenCPN/src" it will work exactly the same (except "cmake .." which you would have to replace with "cmake ../.." of course), you will just have your build directory elsewhere.
If you feel like you have a better wording for it, which will make it clearer, feel free to edit the page in the wiki.

Thanks Pavel!

You rock.

Where do I find the Wiki for the documents ?

When I run the cmake I get this

CMake Warning (dev) in CMakeLists.txt:
Policy CMP0043 is not set: Ignore COMPILE_DEFINITIONS_<Config> properties.
Run "cmake --help-policy CMP0043" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.
This warning is for project developers. Use -Wno-dev to suppress it.

Anything to care about ?
I'm using Cmake 3.0.2

Hans...
Harmless, some changes in cmake 3+ started to produce this warning, it does not affect us at all.
Most of opencpn.org is a wiki, register, log in and hit the EDIT link on top of the page.

Hans,

I had similar questions. I think that page of the Wiki can be much improved. There are several detains that are not clear. I'm willing to help with updating that page along with you.

[hasse_A]

transmitterdan....

Yes. I just did some editing of the wiki.
I will continue as I go along and get the debug environment up
an running again. I am working on the xHD radar overlay and after Pavel
helped me converting the new code I am taking a new shot at it with a clean start.

Okay so now debug build works without errors.

But............
not release
Says it is missing a CMakeLists.txt in release.

I suspected release directory didn't even have to exist either.

Hans...
Never seen this one and does not make sense - build/release should never be source directory, it is created during the build. Try to purge the build dir completely and do

cmake ..
cmake --build . --config release

again

Pavel

[hasse_A]

Nope, that made no change and
now the same thing happens with debug.

It builds ok with VS2010.

[nohal]

That's really weird. Can you attach your CMakeCache.txt? I think I never had cmake 3.0.2 on the Windows machine, but there was no problem with 2.8 and certainly there is no problem with 3.1 now.

Pavel

[hasse_A]

Sure can.
Here comes.

Had to trick the system. 60k .txt....... no way.

/Hans

[hasse_A]

Sorry wrong file. Hold.

/Hans

[hasse_A]

New try.

Pavel .....

It's getting quite late over here. I think I will have to get horizontal now.
Have to be up at 06:00. Will be at it tomorrow again.

There are some other peculiar things.
VS2010 wants to rebuild ZERO_CHECK every time I start debugging.....
Post what ever you find out and I'll check tomorrow.
