* | | binutils: Disable glob for better portabilityAlexey Brodkin2020-10-141-0/+4
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since glibc 2.27 glob interface was changed [1] and so "glob" & "glob64" symbols require glibc 2.27+. For us that means if we build Binutils on a machine with glibc 2.27+ produced binaries won't be any longer usable on machines with older glibc. As an example [2]: build on Ubuntu 18.04 (with glibc 2.27) and try to run on CentOS 7.x (with glibc 2.17), you'll see this: ---------------------->8------------------- ldd ld ld: /lib64/libc.so.6: version `GLIBC_2.27' not found (required by ld) ---------------------->8------------------- Now given glob is not really used by Binutils itself (only needed by GDB) and we build Binutils & GDB separately let's make at least Binutils more portable. In theory we may even try to do the same hack for GDB forcing it to use imported glob implementation. But since GDB is now built strictly by C++ compiler we'll get waaay to many incompatibilities due to multiple changes of C++ ABI in between GCC 7.5 of Ubuntu 18.04 and GCC 4.8.5 of CentOS 7.x, so there's no point to even try.

* | Enable static libgcc when CT_GDB_NATIVE_STATIC_LIBSTDCXX is setStephanos Ioannidis2020-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates the GDB build script to specify `-static-libgcc` when `CT_GDB_NATIVE_STATIC_LIBSTDCXX` is enabled. Both libgcc and libstdc++ are considered to be part of the "standard libraries," and should be specified by the same flag (the configuration symbol could potentially use a better name and/or further indirection). This also semantically aligns the `CT_GDB_NATIVE_STATIC_LIBSTDCXX` with the equivalent GCC configuration `CT_CC_GCC_STATIC_LIBSTDCXX`, which also enables static linking of both libgcc and libstdc++.

From Glibc's standpoint multilib is just multi-ABI [1] and so very limited versions are supposed to co-exist (e.g. arc700 & archs). Here we force Glibc to install libraries in GCC's multilib folder to create a universal cross-toolchain that has libs optimized for multiple CPU types. But note we only need to mess with installation paths in case of real multilib, otherwise we keep default "lib/" paths so that GCC finds default (the one and only) libs where it expects them to be. Also here we add a sample which allows to build universal Glibc Linux toolchain for ARC.
