Libzip mess (ROOT cmake problem)

ROOT
1

Hi,
building ROOT from source (git head)
find_package(ZLIB REQUIRED) from core/zip/CMakeLists.txt returns ZIP lib from my Postgre14 installation (cause it’s in the $PATH) which is wrong.
How to avoid this mess and to force to use the “builtin ZIP”?
Why “the builtin ZIP” is not a default option?

Hi Valeriy,

Add the -Dbuiltin_zlib=ON CMake option, or check it in the cmake-gui.
And is it on Windows? We could consider making builtin_zlib=ON by default. Note that this kind of issue might occur with other options.

Cheers, Bertrand.

Yes, it’s win.
Bertrand, check the git-head.
I could’nt build.

… and there are many errors with RooFit

I build every day, and our CI incremental build is green on Windows. What are the errors you got? Which version of Visual Studio? Which configuration (Win32/Win64)?

VS22.
I’ll re-check it again.
Bertrand, why not “raise builtin priority”?

7

I’ll check. Note that it’s the first time someone has this issue on Windows…

Bertrand,
it’s pity
but old good days of 10K ROOTscribers are gone when such news be bomb

I see obvious ROOT degradation, after R&F : (
