Hi,
I am trying to compile root on Ubuntu 24.
I first tried with root 6.26.10 and I get errors of the type:
In file included from /export/CHLOE/VIP/MY_GAMOS6_Ubuntu24/external/root/6.26.06/root/rootbuild/builtins/xrootd/
XROOTD-prefix/src/XROOTD/src/XrdOssCsi/XrdOssCsiRanges.cc:33:

TD/src/XrdOssCsi/XrdOssCsiPages.hh:95:22:
error: field ‘fn_’ has incomplete type ‘const std::string’ {aka ‘const std::__cxx11::basic_string<char>’}
95 | const std::string fn_;

tring<char>’}
72 | class basic_string;
| ^~~~~~~~~~~~
Then I moved to root version 6.30.08.
For this version, I had to change a cmake flag from Dcxx17 to Dcxx20: -Dimt=OFF -Dpythia6=OFF -Dcxx20=ON
But even so, something goes wrong during compilation, after doing 79%:
[ 79%] Built target RooFitJSONInterface
gmake[2]: *** No rule to make target 'builtins/openssl/OPENSSL-prefix/lib/libssl.a', needed by 'lib/libNet.so'. Stop.
gmake[1]: *** [CMakeFiles/Makefile2:36333: net/net/CMakeFiles/Net.dir/all] Error 2

CHECKING /export/CHLOE/VIP/MY_GAMOS6_Ubuntu24/external/root/6.30.08/root/lib/libImt.so
!!! ROOT HAS NOT BEEN PROPERLY INSTALLED !!!
So, is there a root version that can compile on Ubuntu 24? Or is there a way to fix the above error?
