Here's the libtool version:

FruityComputy:build user$ libtool -V
Apple Inc. version cctools-921.0.1

I could try switching to glibtool, not sure if it'd help though.

Any help would be appreciated.

You can try to invoke cmake with -G Xcode and then compile using xcodebuild -configuration Release or xcodebuild -configuration Debug, respectively.

I currently have a fix for that pending in #675, so for the meantime Xcode can be used to build OpenRW on macOS. (macOS is a really annoying target due to having a constantly broken build process).

[snshn]

Yeah, I feel like Apple is quite selfish when it comes to making changes. Thank you for the tips @christoph-heiss!

[madebr]

Thanks @christoph-heiss !
Does this mean the information on the wiki is wrong?

I have another little question:
Does openrw build on macosx when using the gcc or clang toolchain?

[christoph-heiss]

I would not consider to be wrong per se, it is just that macOS 10.14 broke building with Make/Ninja again.

The “official” one on travis CI is too build using Xcode - so maybe remark that in the wiki.

OpenRW does build with both, (homebrew’d) clang and gcc-8, it is just a matter of wrong compiler flags being passed.

[snshn]

I was able to build openrw using Xcode following your tips, thank you @christoph-heiss
Not closing the issue as this build method is not consistent with what's in the wiki, but please feel free to close it any time, before or after being fixed.

[Ryder17z]

Better to keep it open until fixed imho

I've edited the build instructions on the wiki to include the following command to build openrw for visual studio and xcode:

cmake --build . --config Release

I've edited the build instructions on the wiki to include the following command to build openrw for visual studio and xcode:

cmake --build . --config Release

That doesn't work for me on Mojave, I tried Debug as well no luck.

Edit: I have removed that

if(CMAKE_CXX_COMPILER_ID STREQUAL "AppleClang") set_property( TARGET "${ORW_TARGET}" APPEND PROPERTY STATIC_LIBRARY_FLAGS "-no_warning_for_no_symbols" )

that from cmake_configure.cmake and it compiled fine.

@Damianbal
I've updated the Mac OS X version to 10.14.4 on travis CI: https://travis-ci.org/madebr/openrw/jobs/531108431
It does not reproduce your problem.

Can you please post the complete output of configuration + build to a gist? Thanks!

[gbudny]

I have a different issue when I try to compile it :

Can you help me?

[dracc]

@gbudny; What's your output from running ar -V?

Edit: nevermind, your issue is the same exact one as described by OP. Please try the solution suggested by @Damianbal.

[gbudny]

@dracc @Damianbal

Thanks.

I compiled it, but I see many warnings:

Building on Mac now works with both Xcode and regular Makefile!
(Except rwviewer and rwtools since for some reason qt5 cmake stuff is missing from homebrew)
