GL/glew.h not found when building root 6.20

[Diego]

Dear all,

After executing

cmake --build . – -j2

I am having the following fatal error when building root 6.20.02:

glew 2.1.0_1 is already installed in my machine and it is apparently linked. I am running in mac os Catalina 10.15.3.

Thanks for helping!

@oshadura looks like the same issue as in this other post, right?

Build problem on Catalina

Hi! Can you please try to enable -Dbuiltin_glew=ON?

[oshadura]

I opened Jira issue: https://sft.its.cern.ch/jira/browse/ROOT-10631

[Diego]

It worked now!
Thanks!

[oshadura]

here is PR as well coming here: https://github.com/root-project/root/pull/5199

[oshadura]

Could you please try if this fix help to solve situation when you have -Dbuiltin_glew=OFF (https://github.com/root-project/root/pull/5199)

Thanks a lot in advance!

Hi,
Executing with -Dbuiltin_glew=OFF , I have the following message:

[ 98%] Linking CXX shared library …/…/lib/libRGL.so
ld: library not found for -lGLEW
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hi! Sorry for late reply, I wanted to reproduce your failure and I wanted to ask how did you install Glew?

[Diego]

Hello,
I did this: brew install glew

Diego

[oshadura]

At the end, sadly it appears to be a bug in CMake 3.15-3.17, and we disabled for Mac OS X an option with builtin_glew=OFF. Out of curiosity, we would like to ask you why you needed install glew from brew (it it a requirement of other application)?

Thank you again so much for your report!

[Diego]

Hello,
Thanks for fixing it! About glew, it seems that it was not installed in my machine (and I do not know if I need for any other application).

Cheers
