Hi All: I want to build a c++ cross-toolchain from gcc source code. which I'm not sure is that libstdc++ depends on libc? In my experiment, I found that it is only possible to built c++ compiler after libc(uclibc, newlib,...) is compiled and installed. I did not find any clue about this kind of dependency in docs, So please help, any tips will be ok Thanks in advance! -- Best Regards.
