docs/manual: centralize recommendations about BR2_DL_DIR

2017-02-07T13:55:02+00:00

We currently have two places where we recommend where BR2_DL_DIR should be set: "Environment variables" and "Location of downloaded packages". The former recommends setting BR2_DL_DIR in the .config, the latter kind of endorses using ~/.bashrc. We prefer suggesting the ~/.bashrc way since it avoids downloading the same file multiple times, and anyway it's wise to have all the details in a unique place. So remove the .config suggestion from "Environment variables" and let it just point to "Location of downloaded packages". Cc: "Yann E.

docs/manual: suggest 'YES' as the value for LIBFOO_GIT_SUBMODULES

2017-02-07T13:47:04+00:00

The manual mentions LIBFOO_GIT_SUBMODULES but does not tell what value it should have. The implementation only checks whether the variable is non-empty, but we should suggest a specific value to avoid people wondering what they have to set, and to try setting weird values.

support/dependencies: ensure we have 'file' on the host

2016-12-27T17:02:42+00:00

Recently, the autoconf macros for libtool started using '/usr/bin/file' to determine the type of library that is generated by the toolchain. Packages that use this recent version of the libtool autoconf macros will fail in a rather dramatic way when /usr/bin/file is not present on the host: the package will still build but no shared library is generated, which in turn may cause build failures in other packages that link with it. For example, libpng's configure determines that it is not possible to build a shared library on MIPS64 because the expected output from 'file' is not present. Therefore, only a static libpng.a is built. Later, bandwithd links with -lpng but it doesn't use the pkg-config's Private-Libs (because it's not linking statically) and it doesn't have access to the NEEDED reference from the shared library. Therefore, it doesn't link with zlib and fails with pngrutil.c:(.text+0x55c): undefined reference to `inflate' We cant use host-file because it is itself an autotools package and is itself using libtool, so this would be a chicken-n-egg problem. Besides, the libtool script really wants to call /usr/bin/file, so it would not even find our host-file anyway. So, just require that '/usr/bin/file' is present on the host. Signed-off-by: "Yann E.
