Use at your own risk, and report success and/or failure. +config DEMULTILIB + bool "Attempt to combine libraries into a single directory" + default y if !MULTILIB + depends on !MULTILIB || EXPERIMENTAL + help + Normally, Crosstool-NG installs the libraries into the directories + as the configure for these libraries determines appropriate. For + example, for AArch64 glibc wants to install the libraries into + /lib64 but the default dynamic linker path is /lib/ld-linux-aarch64.so.1 + (which is installed as a symlink to ../lib64/ld-VER.so). + + However, not all consumers of the toolchain can handle the libraries + residing in multiple directories. To appease them, crosstool-NG can + attempt to combine the libraries back into a single /lib directory and + create all other directories as symlinks to /lib. This requires all + the library names to be unique within each sysroot. + + Note that GCC may also use separate sysroots for different multilibs. + Hence it may make sense to enable this option even for multilib toolchains. + However, separate roots are rare (any other architecture aside from + SuperH using them?) and hence not well tested in crosstool-NG; therefore, + this option is experimental when MULTILIB is enabled. + #-------------------------------------- config ARCH_SUPPORTS_BOTH_MMU bool |
