Hi all,
I just got compiler errors while I am trying to build root from source in my laptop (Mac OS 10.14.2, Mojave) with g++-8 compiler.
First I got an error as:
Building CXX object core/macosx/CMakeFiles/Macosx.dir/src/CocoaUtils.mm.o cc1objplus:
error: argument to '-O' should be a non-negative integer, 'g', 's' or ‘fast'
As suggested in this topic - Mac os x, gcc-6 compile error, I should switch to X11 other than cocoa.
But I just found that X11 is no longer included with Mac, so I just installed the XQUARTZ, then I trying to cmake it with:
cmake ../source -Dcocoa=OFF -Dx11=ON
And I got another error as
[ 70%] Building CXX object rootx/CMakeFiles/root.dir/src/rootx.cxx.o
In file included from /Users/cheng/Software/root/source/graf3d/glew/src/glew.c:49:

Below I pasted the log file of cmake ../source -Dcocoa=OFF -Dx11=ON :
