- From what I could grep, MACOS_VERSION_PATCH isn't used anywhere.
Should we maybe remove it instead of adding code for something that's not used?

Re: [osg-users] [build] Xocde 7.1 with osgDB compiler error

[Radu Popescu]

Hi,

We are using OSG for a cross-platform application that runs on Windows, Linux 
and Mac OS X (10.10 and 10.11).

The application uses OSG 3.4 and Qt 4.8 and we had to apply some patches to get 
this setup working. We maintain a public Git clone, based on the GitHub mirror 
of OpenSceneGraph.

I don't have enough posts on this forum to include a link to the repo. I can 
share it by private messages or some other way, if anybody is interested.

We are using this Git clone internally and we haven't had the time to clean it 
up and submit these changes back upstream (we're not even sure all the changes 
we've made are general enough to be integrated upstream).

Here is a patch that could help with the compilation:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index ce2815b..3e496c1 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -180,7 +180,13 @@ IF(APPLE)

+ELSE()
+SET(MACOS_VERSION_PATCH "0")
+ENDIF()
 
 SET(OSG_OSX_SDK_NAME "macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")



Additionally, here are the CMake configuration flags we are using to compile 
OSG:

cmake \
-DCMAKE_BUILD_TYPE=Release \
-DOPENGL_PROFILE="GLCORE" \
-DCMAKE_EXE_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_MODULE_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_SHARED_LINKER_FLAGS="-stdlib=libc++" \
-DCMAKE_OSX_ARCHITECTURES="x86_64" \
-DOSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX="imageio" \
-DOSG_WINDOWING_SYSTEM="Cocoa" \
-DDESIRED_QT_VERSION=4 \
-DQT_QMAKE_EXECUTABLE=/usr/bin/qmake \
-DDYNAMIC_OPENSCENEGRAPH=OFF \
-DDYNAMIC_OPENTHREADS=OFF


I hope this helps!

Best regards,
Radu

Re: [osg-users] [build] Xocde 7.1 with osgDB compiler error

[Robert Osfield]

Hi Radu,

What errors do you see with your build when you don't include the
IF(MACOS_VERSION_LIST_LENGTH EQUAL "3") block to avoid querying the
MACOS_VERSION_PATCH?

With this block I'd be inclined to use GREATER 2, rather than EQUAL 3 just
in case the MACOS implementation adds a forth element to the list.

Robert.

Re: [osg-users] [build] Xocde 7.1 with osgDB compiler error

[Robert Osfield]

Hi Guys,

I don't have an OSX system to test against, but I've gone ahead and had a
bash at implementing what I think might be appropriate.  I need it tested
by OSX users though before I check it into svn/trunk and OSG-3.4 branch.
I've used Radu's suggest change to CMake to avoid checking the 3 entry in
the MACOS_VERSION_LIST if it doesn't exist, and changed the OSX version
check to use > 10.7 rather than one of 10.8, 10.9 and 10.10.  This should
provide support for future rev's of OSX till it hit's 11.x.

Could you guys these it out and let me know?

Cheers,
Robert

Re: [osg-users] [build] Xocde 7.1 with osgDB compiler error

[Robert Osfield]

Hi Daniel,

I don't have an OSX system to test against so have to defer to OSX users
for maintaining the build, I can only provide general guidance.

>From the look of the error line:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/sys/cdefs.h:707:2:
error: Unsupported architecture
#error Unsupported architecture

It looks to me like part of the 10.11 SDK doesn't support build under all
architectures.  You'll need to go into Cmake and select change the
architecture this is built against. Have a look at the
CMAKE_OSX_ARCHITECTURES value.

Just look at the OpenSceneGraph/CMakeLists.txt lines where it sets
CMAKE_OSX_ARCHITECTURES It has the following:

# Set defaults for Universal Binaries. We want 32-bit Intel/PPC on
10.4
# and 32/64-bit Intel/PPC on >= 10.5. Anything <= 10.3 doesn't
support.

# These are just defaults/recommendations, but how we want to build
# out of the box. But the user needs to be able to change these
options.
# So we must only set the values the first time CMake is run, or we
# will overwrite any changes the user sets.
# FORCE is used because the options are not reflected in the UI
otherwise.
# Seems like a good place to add version specific compiler flags
too.

Doesn't include the 10.11, so try adding this into the list.
