Root catalina bug report


Please read tips for efficient and successful posting and posting code

_ROOT Version:6.18.04
_Platform: Mac OS X catalina
_Compiler: system default clang


#include in aa.cpp

running program with debug mode cause header error(see below).
root aa.cpp++g
however without debug mode is OK.
Is it a bug?

Having a similar issue compiling ROOT on a OSX Catalina machine. CLI tools are installed and looks like cling is looking for the headers in the wrong place, namely

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/

instead of

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include

Cheers,

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.

Axel.
