[Buildroot] [PATCH 0/2] Fix problems related to Blackfin lacking AI_ADDRCONFIG

[Buildroot] [PATCH 0/2] Fix problems related to Blackfin lacking AI_ADDRCONFIG

[Thomas Petazzoni]

Hello,

The Blackfin external toolchains provided by Analog Devices don't have
AI_ADDRCONFIG enabled in their uClibc configuration. But since
Buildroot has it enabled in its default uClibc configuration, our
packages make the assumption that it is available.

This causes some build failures in the autobuilders (and possibly for
users), so this set of two patches prevent the selection of packages
that require AI_ADDRCONFIG when a Blackfin toolchain from ADI is used.

Long term, it would be better if the toolchains from ADI had
AI_ADDRCONFIG enabled in their uClibc configuration.

Best regards,

Thomas

[Buildroot] [PATCH 1/2] czmq: prevent selection when ADI Blackfin external toolchains are used

[Thomas Petazzoni]

czmq fails to build with the Blackfin external toolchains provided by
Analog Devices, because their uClibc configuration doesn't include
AI_ADDRCONFIG. In order to prevent such build failures to happen, we
simply prevent the selection of czmq or one of its reverse
dependencies when such toolchains are used.

[Buildroot] [PATCH 2/2] libtirpc: prevent selection when ADI Blackfin external toolchains are used

[Thomas Petazzoni]

libtirpc fails to build with the Blackfin external toolchains provided
by Analog Devices, because their uClibc configuration doesn't include
AI_ADDRCONFIG. In order to prevent such build failures to happen, we
simply prevent libtirpc from being selected when such toolchains are
used. This is not a big problem, since they provide native RPC
support.

Also, since they provide native RPC, we don't have to propagate this
new dependency to the reverse dependencies of libtirpc, because they
all use native RPC when available. The exception to this rule is the
rpcbind package, which can only use the libtirpc implementation of
RPCs, and not the native one of C libraries. Therefore, the dependency
is propagated to the rpcbind package.

Fixes:
