Build problem on Catalina

ROOT
1

Hi,

I’m having build problems of version 6.20 on Catalina with the latest Xcode. I’m using:

cmake …/root-6.20.00/ -DCMAKE_INSTALL_PREFIX=/usr/local/root -Droofit=ON -Dtmva=ON -Dminuit2=ON -Dpython=ON

cmake --build . – -j4

but I have a problem with missing GL/glew.h

Do you have any suggestion?

Thanks,

Looks like it is not finding glew, can you try to build with -Dbuiltin_glew=ON ?

@oshadura

Lorenzo privately suggested to try with -Dgl=OFF. I’m rebuilding right now, will let you know how it goes (it’s taking time…)

-Dgl=OFF doesn’t help, I’ll try with -Dbuiltin_glew=ON. But will take time with trial and error. Is there any tested recipe for Mac OS Catalina?

@llista yes we build with Catalina and with the latest Xcode. -Dbuiltin_glew=ON should help you, but it is very strange that it was not enabled automatically. Do you have opengl=ON?

Can you send me please output of your configuration step (when do you run cmake)

Got worse now:

@Axel can you help us please to understand what is happening on Catalina with latest XCode?

check here: Root catalina bug report

Well, the bug report says:

These issues are fixed in the HEAD of the 6.18 branch and the master. Alternatively just download https://root.cern/download/nightly/root_v6.18.99.macosx64-10.15-clang110.pkg or the upcoming v6.20/00 or v6.18/06.

I’m actually using ROOT 6.20.00. What should I do?

Hi Luca,

  • Could you share your CMakeCache.txt?
  • Did you upgrade and then continue with the same build?
  • What’s the output of compiling
// test.cxx:
auto b = isfinite(0.2);
return 0;

$ clang++ -c test.cxx

Axel.

clang++ -c test.cxx
test.cxx:1:1: warning: ‘auto’ type specifier is a C++11 extension [-Wc++11-extensions]
auto b = isfinite(0.2);
