Regex conflict while compiling

[Daandelange]

Hello Emanuele / World,
I'm giving trying to compile Mosaic but I'm stuck on a compilation conflict and would like some insight.

• Mosaic/src/TextEditor.h includes <regex> which loads /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/regex.
• ofxPython includes /usr/include/python2.7/pyport.h which sets a macro: #define tolower(c)... that overrules the regex's tolower function-like macro.
• Compilation throws an error : too many arguments provided to function-like macro invocation __ct_->tolower(&__s[0], &__s[0] + __s.size());.

I guess this is some kind of conflict between python 2.7 and libc++::regex.
Before digging further, I'm wondering how you don't get this error (if so). Might this be related to Apple's libc++ implementation ?

Do you have any clue about this ?

My configuration : Mosaic master (0.3.2) + OF 0.11.0 (release) + QT Creator 4.6.1 + Osx 12.12
My Qt Desktop kit is configured to compile with Apple Clang++ (within XCode); using /usr/bin/clang++ throws lots of errors anyways, nor does it compile OF.
I'm able to compile other OF projects using this same configuration.

Edit: I'm using Xcode 8.1 which holds libc++ ; I'll try to update that and report back.

Hi Daan,

the problem is probably about the osx version, do you mean 10.12 (Sierra) ?

I'm compiling on High Sierra (10.13) and Mojave (10.14) without problem, while the rest is the same, latest Mosaic code, OF 0.11.0 (works with 0.10.0 and 0.10.1 too) and QT Creator 4.6.1.

Another problem could be the Apple Clang++, i'm compiling with GCC (/usr/bin/) for both C and C++ x86 64bit.

I hope that helps, let me know if more problems appears.

Thanks for these infos. (yes I meant 10.12)
I got it compiling with /usr/bin/ but no change.
So I guess it's my OS, which I can't upgrade right now. :(

I isolated the issue to ofxPython (so it's not directly Mosaic) and found a dirty workaround. Alternatively Python 2.7.13 should also fix this.

Getting closer : Now I'm running into some linker errors, many *.a files are for 10.11 while I'm linking for 10.9. That might be more related to OF in general.
Do you link against 10.9 ? (I suppose yes, as the release runs on 10.9?)

For now, adding 'QTKit' to the .qbs's of.frameworks and adding cpp.minimumOsxVersion: "10.11" lets me compile a custom-build binary !
Running it requires me to manually copy libndi.3.dylib next to the binary (and run your script).

🎉

There's some crashes, but at least I got it compiling.

I'm happy you got it compiling!

About the errors/warnings:

I'm thinking in upgrade python to python3, so probably refactoring the code will solve the actual compiling issues with python

Yes, i'm linking against 10.9, just to leave OF defaults untouched, so when you compile on a different version the compiler will give you a warning about a library built for a newer OSX version, but that is usually not a problem at all (at least i've never had one related to that)

About the libndi.3.dylib, yes, my mistake, i use the OF embedded compile script to search for .dylib files inside lib folder and copy it next to the binary (OF do that for libfmodex), but it's not properly automated nor documented yet (and it's a OSX only issue, not needed on linux)

Let me know how is working, there is no manual or proper documentation yet, i'm beta testing right now, cleaning code and fixing bugs, but i'm starting with the manual too, empty now but you can check it here: https://github.com/d3cod3/Mosaic-Manual

And there is the official page with some documentation about 70% of the objects:
