Building OCPN on OS X

[Mollymawk]

I'm trying to build OpenCPN on my Mac (OS X 10.10 Yoesmite), but I'm having a bit of trouble.
Pavel's updated build instructions are a help, and Gerhard - who has built OCPN on Yosemite - has given me some advice via PM, but I'm still not managing and I thought I'd post here rather than continue PM'ing so the solution is around for posterity.

I have Xcode 6.1, with the SDKs for 10.10 and 10.9 built into it. I have the SDK for 10.8 symlinked.
(I have an old Xcode 4 installer package around from which I will later try to extract the 10.7 SDK, but I know Gerhard managed to build against the 10.10 SDK so it shouldn't be necessary.)


I'm going to start by listing the problems I've had and 'solved', in case it helps anyone see where I'm going wrong.
My current problem is right at the bottom.


My first problem was with building wxWidgets. I was using the latest stable version, 3.0.2, as instructed on the build instructions page. But I was linking against the 10.9 SDK since I didn't have 10.7 and 10.9 was the oldest I had.

Not far into the build, I would get the following error:

/Users/caesar/Downloads/wxWidgets-3.0.2/bk-deps gcc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/ -mmacosx-version-min=10.9 -c -o wxtiff_tif_lzma.o -DNDEBUG  -I./src/jpeg -I/Users/caesar/Downloads/wxWidgets-3.0.2/src/tiff/libtiff -I./src/tiff/libtiff -dynamic -fPIC -DPIC -D_FILE_OFFSET_BITS=64 -DwxDEBUG_LEVEL=0 -I/Users/caesar/Downloads/wxWidgets-3.0.2/lib/wx/include/osx_cocoa-unicode-3.0 -I./include -Wall -Wundef -O2 -fno-strict-aliasing -fno-common  ./src/tiff/libtiff/tif_lzma.c

         ^
1 error generated.
make: *** [wxtiff_tif_lzma.o] Error 1

I was able to solve this error by passing the flag --disable-lzma to the configure script. Then, make would run for a very long time (an hour?) before throwing the following errors:

Following Gerhard's advice, I pulled the latest wxWidgets sources from Github, and used the following configure command:

../configure --with-osx_cocoa --enable-debug --enable-shared  --with-macosx-sdk=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk  --with-macosx-version-min=10.9 --enable-unicode --enable-mimetype=yes --disable-lzma

Then wxWidgets built successfully.


BUT... I wasn't able to build OpenCPN.
First I got the following error:

CMake Warning at /usr/local/Cellar/cmake/3.0.2/share/cmake/Modules/Platform/Darwin.cmake:179 (message):

-- Configuring incomplete, errors occurred!

So then I installed the 10.8 SDK, and cmake would run fine.
But when I ran make, I got the following error...:

Suspecting that this was due to building against an older SDK than I'd used to build wxWidgets, I changed every mention of 10.8.sdk to 10.10.sdk in the CMakeCache.txt file. That solved that problem.


BUT... now I'm getting the following error.

I'm on the point of giving up, but I do really want to get this going so I can at least do some debugging and hopefully even contribute a few improvements to OCPN.

So, if anyone can help me here, I'd greatly appreciate it.

try configuring wxwidgets with --enable-compat28 ?

What does that do?

[Mollymawk]

Latest news:

Pavel tells me I probably do need to use the 10.7 SDK (and definitely need to use wxWidgets 3.0.2 for compatibility with official OCPN).

So I tried that. (Again, I had to use --disable-lzma.)

After about ten minutes, a new error:

wxregexu-3.0   -framework IOKit -framework Carbon -framework Cocoa -framework  AudioToolbox -framework System -framework OpenGL  -lz -lpthread -liconv  -llzma  -lz -lpthread -liconv -llzma

I see, that enables compatibility with wx 2.8. But it seems to be enabled by default in 3.0.2 - presumably you are talking about using master ("3.1") and using that flag?

Try to use Xcode and not these cmake terminal stuff.
Xcode is a nice compiler GUI even for idiots like me.

I would go back to git version of wxwidgets since you got closest there.

The error you posted about the function not existing is related to a change in the newer library version, so I imagined that enabling compatibility would solve it. Maybe needs 3.0 compatibility not 2.8 for this, so you can try both.

If neither work, you can add #ifdef in the opencpn source code to build checking the version and calling the appropriate function.

Ah right. I'm trying to avoid that at the moment since Pavel told me it wouldn't be compatible with official releases of OpenCPN, but I'll come back to it if all else fails.

For the moment, I have managed to get wxWidgets stable to build by using the 10.9 SDK and setting the min-version to 10.7.

I did:

$ ./configure --enable-unicode --with-osx-cocoa --with-macosx-sdk=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk --with-macosx-version-min=10.7 --enable-aui --disable-debug --enable-opengl --disable-lzma

$ make
$ sudo make install

and it built and installed fine.

Now building OCPN... It's got past the point where it failed last time.

I spoke too soon!

It's that same error about missing the System framework.

I'll get to the bottom of this!

[Mollymawk]

I managed to build it!

I had to build both wxWidgets and OpenCPN using the 10.9 SDK (but specifying 10.7 as minimum compatible version).

I think I know what the problem was now, and it's a bit embarrassing I didn't fully think about it earlier.
I put my old SDKs at /SDKs/ and symlinked them from inside Xcode, rather than actually storing them inside Xcode. I'm guessing ld didn't like the symlink.
When building wxWidgets I thought I could get around this by pointing straight at /SDKs/ when calling configure, but I guess that wasn't getting passed on to ld.

Are you able to build installers for the plugins?

[bdbcat]

Mollymawk...

Now that you are able to build OCPN, please download the latest github source, and make a fresh build/test.

There is a proposed correction for FS#1541 (Serious graphics errors with OpenGL enabled) in github now.

Thanks for your input
Dave

Dave,

Done. It works fine.
Well done!

My battery is flat. :-/
I will play with this another time.

But, I think I will first have to rebuild with the 10.7 SDK somehow; if I put my build of the default plugins into the official beta it crashes.

[hmacread]

Mollymawk,

Good work getting it to compile on 10.10.

A few months ago I got a version compiled in 10.9 (Mavericks) with wxWidgets 3.0.1 with a lot of help from Sean (boat_alexandra).

I'm interested to hear if you get many runtime errors with Yosemite (the version your using should now include many of the fixes we made then I'm told). Anyway I'm going to try a build on 10.9 now so I'll report back on this thread as well.

Cheers
