Error in compiling root v6-08-06

[bomben]

Dear all,
I am trying to install root v6-08-06 on Mac Os X 10.12.6.
g++ --version gives:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

cmake --version gives:
cmake version 3.9.3

Here is the error at make step:

Hi, the problem is fixed in master, I’m not sure if there will be a backport to 6.08, maybe @pcanal knows.

Problems during Build and Install of Root v6.10/02

Dear experts, I’m trying to install Root v6.10/02 (downloaded by the git repository) on macOs Sierra 10.12.6, but I have several problems in doing so. I have successfully downloaded Root, checked out the right branch, created a Build Directory and started the compilation. This is exactly what I’m doing in the “/usr/local/” folder (and with “sudo”): <download root and move to /usr/local/> cd root git checkout -b v6-10-02 v6-10-02 mkdir BuildDir cd BuildDir cmake ../ -Dgnuinstall=ON -Dsoversion…

Root 6.10/04 fatal error with xcode9.0-beta

Hi, I have already installed the root 6.10/04 and everything is okay when I started to use it. However, I didn’t do anything but the next time I opened the root, a fatal error is hinted. input_line_1:1:10: fatal error: file ‘/Library/Developer/CommandLineTools/usr/include/c++/v1/new’ modified since it was first processed #include ^ input_line_3:36:10: fatal error: file ‘/Library/Developer/CommandLineTools/usr/include/c++/v1/string’ modified since it was first processed #include ^ | Welco…

Mac OSX xcode command line tools v9.0

Earlier today, my Mac updated xcode and command line tools to v9.0 and now I am not able to compile programs that #include <TROOT.h>. For example, this simple program compiles fine if the #include <TROOT.h> is commented out. #include <iostream> #include <TROOT.h> int main(int argc, char *argv[]) { std::cout << "hello" << std::endl; } Uncommenting the #include <TROOT.h> and compiling with g++ -Wall -o anal anal.C produces the following compilation errors: visitor050:rootInc reimer…

Standalone application compilation error with TString.h

I’m running root 6.10.02 on a mac (Sierra 12.6), and have run into an issue with TString.h and getting an series of errors related to unknown type name issues. To test demonstrate it, I’ve written a simple hello code, #include <iostream> //#include <TString.h> int main() { std::cout << "Hello World" << std::endl; return 0; } which compiles fine, but when I remove the comment from the #include <TString.h> I get the following: >g++ `root-config --cflags --glibs` -o hello test.cc In fil…
