OS X build steps

[phries]

Here's what I've found for running HDRMerge on Mac OS X 10.10 (Yosemite). Not totally successful yet but I got it built and running.

Build

Uses brew package manager. I had a few brews already installed that might have been required too.

• brew install libraw
• brew install cmake
• brew install qt4
• brew install boost
• Download and build the tarball of exiv2 (0.23, not latest). Install it with: sudo make install

alglib (long step for develop branch only)

For the "develop" branch, you also need alglib 3.x.x. The only homebrew formula for "alglib" gives you alglib 2 which is not compatible. Complicating things, neither version of alglib includes any kind of Makefile, so every package manager rolls their own.

For now you can use a quick homebrew formula I wrote for "alglib3":

• brew install https://gist.githubusercontent.com/phries/964ac206335a251c934f/raw/3cbac1af5dd2ecced8f6d46f29e050074db62f31/alglib3.rb

And apply this diff to hdrmerge:

$ git diff
diff --git a/cmake/FindAlglib.cmake b/cmake/FindAlglib.cmake
index 9b80b9a..5903414 100644

Compiling hdrmerge

In build dir:

• cmake ..
• make

Issues

• GUI app crashes in hdrmerge's alignment code when I try to merge the photos.
• Command line creates a merged photo but it's black (see DNG turns out black #52). This may not be Mac-related.

edit 11/30 & 12/5: Worked around earlier need for installing a new compiler, which is time consuming. The program is much more debuggable with the default (XCode) compiler anyway. Compile from my fork, "develop" branch for now if you have compilation errors in things like an algorithm include and lambdas

Thank you for your effort, Phries :)
I managed to build hdrmerge without problem, with latest XCode and brew. I will test it and try to build an installation package to include it with the next stable release. I may also switch Alglib with GSL, which is included in brew.

@phries @Benitoite we intend to release a new version soon, and it would be great if you could provide a dev build for testing, and instructions how to compile it in recent macOS versions.

The latest test .dmg is here: https://kd6kxr.keybase.pub/HDRMerge-f74cf3d.dmg

These steps don't include things like getting Xcode, a MacOS SDK, Qt5, or cmake, etc. Don't have homebrew, nor do I use Xcode extensively, so I did the following to build HDRMerge on the 10.12/14 command line:

1a. Dependencies. Get the dependencies which give you these libraries. Some are from MacPorts and some are built from their code repositories. It is possible to use brew as well.

libexiv2.27.dylib
libexpat.1.dylib
libiconv.2.dylib
libintl.8.dylib
libiomp5.dylib
libjasper.4.dylib
libjpeg.62.dylib
liblcms2.2.dylib
libraw_r.19.dylib
(libz.1.dylib from system)

1b. Download ALGLIB 3.14.0 for C++ and extract to ~/alglib

1c. Clone HDRMerge into ~/hdrmerge and checkout master branch

git clone https://github.com/jcelaya/hdrmerge.git ~/hdrmerge
cd ~/hdrmerge
git checkout master

2. Set the environment variable for alglib:

export ALGLIB_ROOT=~/alglib/cpp

3. Make and goto the build directory.

mkdir ~/hdrmerge/build && cd ~/hdrmerge/build

4. Issue cmake command
   MacOS 10.12 Sierra:

sudo cmake .. -DQt5_DIR=$HOME/Qt/5.11.1/clang_64/lib/cmake/Qt5 -DCMAKE_BUILD_TYPE=Release -DOpenMP_C_FLAGS=-fopenmp="libiomp5" -DOpenMP_CXX_FLAGS=-fopenmp="libiomp5" -DOpenMP_C_LIB_NAMES="libiomp5" -DOpenMP_CXX_LIB_NAMES="libiomp5" -DOpenMP_libiomp5_LIBRARY="/opt/local" -DCMAKE_C_COMPILER="clang-mp-3.9"       -DCMAKE_CXX_COMPILER="clang++-mp-3.9" -DCMAKE_OSX_SYSROOT="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk" -DALGLIB_ROOT=$ALGLIB_ROOT -DALGLIB_INCLUDES=$ALGLIB_ROOT/src -DALGLIB_LIBRARIES=$ALGLIB_ROOT/src -DCMAKE_INSTALL_BINDIR=$HOME/hdrmerge/build/install

MacOS 10.14 Mojave:

 cmake .. -DQt5_DIR=$HOME/Qt596/5.9.6/clang_64/lib/cmake/Qt5 -DCMAKE_BUILD_TYPE=Release -DOpenMP_C_FLAGS=-fopenmp=lomp -DOpenMP_CXX_FLAGS=-fopenmp=lomp -DOpenMP_C_LIB_NAMES="libiomp5" -DOpenMP_CXX_LIB_NAMES="libiomp5" -DOpenMP_libiomp5_LIBRARY="/opt/local/lib/libiomp5.dylib" -DOpenMP_CXX_FLAGS="-Xpreprocessor -fopenmp /opt/local/lib/libiomp5.dylib -I/opt/local/include" -DOpenMP_CXX_LIB_NAMES="libiomp5" -DOpenMP_C_FLAGS="-Xpreprocessor -fopenmp /opt/local/lib/libiomp5.dylib -I/opt/local/include"   -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_C_COMPILER="clang" -DCMAKE_CXX_COMPILER="clang++" -DCMAKE_OSX_SYSROOT="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk" -DALGLIB_ROOT=$ALGLIB_ROOT -DALGLIB_INCLUDES=$ALGLIB_ROOT/src -DALGLIB_LIBRARIES=$ALGLIB_ROOT/src -DCMAKE_INSTALL_BINDIR=$HOME/hdrmerge/build/install

5. compile
   Sierra:

sudo make -j4 install

or for Mojave:

make -j8 && sudo make install

6. Copy some dependencies into Frameworks.

sudo mkdir ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks
sudo cp /opt/local/lib/libomp/libiomp5.dylib ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks/.
sudo cp /opt/local/lib/libexiv2.27.dylib ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks/.
sudo cp /opt/local/lib/libjpeg.62.dylib ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks/.
sudo cp /opt/local/lib/libjasper.4.dylib ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks/.

7. Run Qt5's macdeployqt

sudo  ~/Qt/5.11.1/clang_64/bin/macdeployqt ~/hdrmerge/build/install/hdrmerge.app -no-strip -verbose=3

or

sudo  ~/Qt596/5.9.6/clang_64/bin/macdeployqt ~/hdrmerge/build/install/hdrmerge.app -no-strip -verbose=3

8. Install an rpath, etc.

sudo install_name_tool -add_rpath "@executable_path/../Frameworks" ~/hdrmerge/build/install/hdrmerge.app/Contents/MacOS/hdrmerge
sudo install_name_tool -change /opt/local/lib/libexpat.1.dylib @rpath/libexpat.1.dylib ~/hdrmerge/build/install/hdrmerge.app/Contents/Frameworks/libexiv2.27.dylib 

9. Make the .dmg

sudo hdiutil create -fs HFS+ -ov -srcfolder ~/hdrmerge/build/install/hdrmerge.app ~/hdrmerge/build/install/HDRMerge_$(git describe --tags).dmg

Some things are optional, like libiomp5 instead of clang's libomp. I don't think libiomp5 is required, but it is what I have used. After building other software I find I already had the dependencies except alglib, which took a few minutes to figure out how to incorporate. Also note I'm using the MacOS X 10.9 SDK.
App launched and ran ok in 10.11 and 10.12, should run on 10.9+.

@Benitoite great, I opened a forum for testing:
https://discuss.pixls.us/t/help-test-the-new-hdrmerge-development-build-for-macos/6936

@Benitoite did you compile using the master or the treeclean branch?

[Beep6581]

@Benitoite I will merge treeclean into master soon, @Hombre57 is still going to make a commit before I do, so maybe better if you wait for that. I will ping you when it's done.

[aferrero2707]

I have downloaded the .dmg file, and will start testing it soon...

On a somewhat related note, I have some experience to offer in automating the OSX building/packaging using Travis CI. I have such an automated procedure already set-up and running for another project. It is based on homebrew, and the builds can be either triggered by commits to the relevant branches, or started regularly with CRON jobs...

[Beep6581]

@Benitoite @aferrero2707 branch treeclean merged into master. You can go ahead and test macOS compilation. Feel free to make the required changes to the CMake file, but note that @Hombre57 is also making changes to the Windows sections of that file.

[Benitoite]

@Beep6581 MacOS build commands and CMakeLists.txt changes above updated (branch master)

[Beep6581]

@Benitoite to prepare for release v1.0, are the macOS build instructions still valid?
