From: Jörg Krause Date: Tue, 26 May 2015 10:38:09 +0000 (+0200) Subject: package/mtd: add patch to fix host build error with gcc 5.1 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=77fbc684c56d3d247419c6473c67ba5f60b0c093;p=buildroot.git package/mtd: add patch to fix host build error with gcc 5.1 host-mtd build fails with gcc 5.1: error: redefinition of ‘hashtable_iterator_key’ error: redefinition of ‘hashtable_iterator_value’ Indeed, both functions are defined twice - once in the header and once in the source file. This is permitted in C11 (and maybe in C99).
