From 78e78071128ccf2dba8cf76b00b1beb0c5f3e538 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 18 May 2020 08:26:47 +0200 Subject: [PATCH] package/bison: make installation relocatable Our current host-bison installation is not relocatable, so if you generate the SDK, and install it in a different location, bison will no longer work with failures such as: bison: /home/user/buildroot/output/host/share/bison/m4sugar/m4sugar.m4: cannot open: No such file or directory This particular issue is already resolved upstream by the addition of "relocatable" support, which we enable using --enable-relocatable. Once this issue is fixed, a second one pops up: the path to the m4 program itself is also hardcoded. So we add a patch to fix that as well. The patch has been submitted upstream, which have requested for further refinements not applicable to the Buildroot context; in the meantime, we carry that patch.
