main.cpp compiles successfully from the command line with the following command:
clang++ -std=c++14 -stdlib=libc++ -I/usr/local/include/boost-1_69 -DBOOST_LOG_DYN_LINK main.cpp -o test -L/usr/local/lib -lboost_log-clang6-mt-x64-1_69 -lpthread -lboost_thread-clang6-mt-x64-1_69 -lboost_system-clang6-mt-x64-1_69
2. My eclipse variant is I believe 'R'. The specific filename is: eclipse-cpp-2018-12-R-linux-gtk-x86_64.tar.gz
My goal is to add LLVM (clang) support to Eclipse C++.
The steps are as follows:
Help->Install New Software-> Select "All Available Sites" from the pull down menu next to the Add button.
Select C/C++ Development Tools and C/C++ LLVM Family-Compiler as shown in 20-13-24.png
Select Next->Next->Accept Terms/Finish->(pop up)Restart Now to restart the IDE
From the Preferences menu I now have an LLVM option under C/C++ and will attempt to set library search path directory and LLVM installation folder.
Noteworthy: The LLVM dialog had the following pre-filled entries. The Libraries section had stdc++ and 'Library search path directories had ' /usr/lib/gcc/x86_64-linux-gnu/7/'
If I create a managed project and choose LLVM with Clang (Lang) the search path and stdc++ is reflected as shown in 20-23-55.png.
Herein lies the issue. I've tried to delete ' /usr/lib/gcc/x86_64-linux-gnu/7/' and stdc++ from my project and the LLVM menu to no avail. Those entries keep recurring (coming back) automatically during compilation.
What i want is libc++ not libstdc++ and the path should not reflect 'gcc' but my clang path. How can i fix this?
The installer picks those entries by default and that's not what I want.
