See also "/path/to/my/machine/Downloads/buildroot-6/CMakeFiles/CMakeOutput.log".
See also "/path/to/my/machine/Downloads/buildroot-6/CMakeFiles/CMakeError.log".

for information here is my cmake command:

`cmake ../root-6.20.00/ -Dgminimal='ON' -Dmlp=ON -Dmathmore='ON' -Dfftw3='ON' -Dminuit2='ON' -Dxml='ON' -Dasimage='ON' -Dpython='ON' -Dsoversion='ON' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/path/to/my/machine/root_v6.20.00/

I do have the same issu with 6.20.02
Ideas and suggestions are more than welcome.

Thanks in advance
jb

Sorry, for completness, the version of cmake i’m using is the latest i found: 3.17.0

bellenot · March 26, 2020, 8:16am

Weird. Maybe @Axel has an idea what could be the issue?

jbb · March 26, 2020, 8:21am

Yep, clearly. I thought I might encounter issues (I had to update my cmake for instance) but I never considered something like this … I’ve tried to change the corresponding line by hand (retype it) but that was foolish of me

Sorry for chiming in waaay too late: my bet given the failing line is a directory name with “weird” characters that Python doesn’t manage to encode in ASCII. Did I guess correctly?
