no member named 'unique_ptr' in namespace 'std'

Hi community,

I just cloned the repository, followed the homebrew install instructions in OSX,  and tried to compile . The following is the very first warning and the  first error message that followed. Any help is appreciated.... thanks....

Hi dreylago,

Just double checked: the MuParser code is correct with <memory> header for unique_ptr

You compiling command contains -std=c++11

I'm lost here, if the compiler is too old: g++-4.6 or earlier, -std=c++11 should have been rejected.

still, what's your gcc version?

g++ -v

I am also confused by this... as the flags and version seem correct.
 

One thing:

your gcc is at : /usr/local/

if it's not by MacPorts, could you try gcc from MacPorts?

Is it ok to mix homebrew with MacPorts gcc? my gcc was installed with homebrew. Should I uninstall it first?

Thanks

just try any other (newer) gcc

You can also download Qt-5 (the latest version) and use clang comes with it.
