How to get libtool for gcc-9?

How to get libtool for gcc-9?

[Moritz Lell]

Hello,

When I use an environment like

    LC_ALL=C guix environment --ad-hoc \
      gcc-toolchain libtool grep which coreutils

I get

    gcc --version | head -n1
    # gcc (GCC) 9.2.0

but libtool looks for gcc-7.4.0 libraries:

    grep 'gcc-.*\ ' `which libtool` | sed 's/ /\n  /g'

    # sys_lib_search_path_spec="[...]
    #   /gnu/store/2plcy91lypnbbysb18ymnhaw3zwk8pg1-gcc-7.4.0-lib/[...]"
    # compiler_lib_search_dirs=" [...]
    #   /gnu/store/2plcy91lypnbbysb18ymnhaw3zwk8pg1-gcc-7.4.0-lib/[...]"
    # postdep_objects=\
    #  "/gnu/store/2plcy91lypnbbysb18ymnhaw3zwk8pg1-gcc-7.4.0-lib/[...]
    #  compiler_lib_search_path="[...]
    #  -L/gnu/store/2plcy91lypnbbysb18ymnhaw3zwk8pg1-gcc-7.4.0-lib/
    #  [...]"


How can I get a libtool that uses the libraries of gcc-9.2.0?

Best,
Moritz

The ‘libtool’ executable provided by the ‘libtool’ package doesn’t
really matter.

Normally, Libtool is copied in package sources using ‘libtoolize’; only
when you run ./configure is a ‘libtool’ script generated for the program
you’re about to build.

HTH!
