/bin/ld: cannot find -lc++
by hmarzooq from LinuxQuestions.org on (#5T1D4)
Hello!
I'm facing a problem where a make file is throwing below error:
Code:/bin/ld: cannot find -lc++The shared library in error (lc++) is part of libc++ which I've build and installed. However, the make file is not able to find this library. Therefore, I'm assuming this is an issue of a linker (ld) not able to search the lc++ lib in the search path.
Assuming the actual error i.e. Quote:
means that linker (ld) cannot find lc++ in the search path, I did investigate below (RPATH issue) and fixed the "not found" issue and re-run make clean & make after removing/creating build dir.
