cf_gen.cc is compiled by host compiler and unconditionally uses auto
since bump to version 6.6 in commit
c13199c932 and
09835feb25
resulting in the following build failure with host gcc < 8:
/usr/bin/g++ -O2 -I/home/buildroot/autobuild/run/instance-1/output-1/host/include -o cf_gen ./cf_gen.cc -I. -I../include/ -I../src
./cf_gen.cc: In function 'int main(int, char**)':
./cf_gen.cc:268:63: error: forming reference to void
auto &newEntry = entries.emplace_back(name);
^
So add a dependency on host gcc >= 8 and gcc >= 8 as advocated by
upstream in
9d3433c4ac/doc/release-notes/release-6.sgml.in:
This release adds a dependency on C++17 support in any compiler used to build Squid.
GCC 8+ and Clang 8+ support C++17.
While at it, drop BR2_TOOLCHAIN_HAS_GCC_BUG_64735 which is always false
with gcc >= 7
