master build fails on mac os

[x37v]

libossia: 8fee847c5e809dcc91f1f79c93eea4069a056be4 i'm on osx 10.15.7 with xcode 11.7. seems like I should be good according to https://github.com/OSSIA/libossia/wiki/Building#building-libossia-and-tests-on-macos-on-the-command-line

Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project ossia.xcodeproj build -target ALL_BUILD -configuration Debug -hideShellScriptEnvironment

User defaults from command line:
    HideShellScriptEnvironment = YES

I have a branch that builds: https://github.com/ossia/libossia/compare/master...Cycling74:libossia:xnor/master-build Though some tests fail, i'm not sure if those tests failed before or not. There was also a note Note : if this is changed, also change the Qt version in js_utilities.cpp but I didn't find/change the appropriate thing to change.

[jcelerier]

arf, can you try going into src/ossia/detail/ssize.hpp and replacing __MAC_OS_X_VERSION_MIN_REQUIRED >= 113000 by e.g. 114000? Or even just #ifdefing the whole thing to make sure that it builds this way

[x37v]

incrementing to 114000 solved the ssize failure, still failing on FullMatch

[jcelerier]

hmmm checking into re2's code it seems that there is an overload which depends on __cpp_lib_string_view being defined. wild that xcode 11.3 didn't yet provides it even though it provided the type... trying to think of a fix

[jcelerier]

I'm wondering: what does it give if you try to run CMake with -DCMAKE_CXX_FLAGS="-D__cpp_lib_string_view=201803L" to try to force things a bit ? Maybe they didn't define the flag at the time because not all member functions were implemented but with some luck we aren't using them.... the only reference to __cpp_lib_string_view I could find in ossia's source tree is in re2

[jcelerier]

nevermind, there's an overload that takes (const char* data, size_t size) ; i'll just change the code to use that

[jcelerier]

can you try at current git master?

[maybites]

I just tried to compile it on my machine and have the same problem: with current master [514c7f5bf] and follwoing these instructions: https://github.com/ossia/libossia/wiki/Building#building-the-max-implementation-on-macos

[jcelerier]

agh, and can you tell me which version of Xcode you are using ?

[maybites]

Version 12.4 (12D4e)

[jcelerier]

hmmm... I wonder if it's still the same with a clean build? It looks like it could be using an old Xcode SDK maybe? Can you send me the CMakeCache.txt at the root of the build folder?

[maybites]

CMakeCache.txt

[jcelerier]

okay, it's Xcode 12 but with the macosx 11.1 sdk:

 CMAKE_OSX_SYSROOT:PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk

can you try to run

 cmake . -DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

to set it to the last version ? if I'm not mistaken that's the right path but cannot check on my mac right now

[maybites]

I cleaned the 'build-max' folder and executed

cmake ../libossia -DOSSIA_EXAMPLES=1 -DOSSIA_TESTING=1  -DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

which was running without issues

but my error reported above when executing 'make' still persists.

[jcelerier]

hmmm... can you send me the new CMakeCache.txt from this build ? I wonder if there isn't some package which tries to force-use the MacOSXA.B.sdk somewhere

[jcelerier]

.. at worst, can you try to move it somewhere else temporarily and do a clean build ?

[maybites]

I just did a clean clone and build, same error.

CMakeCache.txt

[jcelerier]

okay, I can see still the line in the CMakeCacke.txt:

CMAKE_OSX_SYSROOT:PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk

so there seems to be something in either our cmake code or a third party dep, that forces to it when it is detected. I will try to simulate on my mac by adding the SDK manually and seeing where things go wrong.

In the meantime:

could you make a clean build folder and run:

1/ the command

  cmake /* usual cmake build commands */ --trace > trace.log
  // send me trace.log
  // clear the build dir

  cmake /* usual cmake build commands */ --trace-expand > trace-expand.log
  // send me trace-expand.log

this way I can see exactly where the issue happens in your machine in case I cannot reproduce on mine. thanks, sorry for all the steps... debugging build issues on mac are always a pain ahha

[maybites]

trace.log

trace-expand.log

[jcelerier]

oops... had a typo in my message sorry. It's 2> not >. But even in the log you showed it talks about DNSSD - i'll investigate around this part first so don't worry about runnign the commands again
