With bootgen 2025.1, the directory structure was re-done. In the process of
doing this, the source files in the bisonflex directory lost the fix below
which had been applied on an earlier version of bootgen for the issue below.
Bootgen embeds an old version of flex, but uses the system include syntax
(#include <>) to reference it, causing conflicts on systems with the
development headers for a modern flex version installed, leading to build
issues like:
../bisonflex/bif.yy.cpp: In member function 'virtual int BIF::FlexScanner::yylex()':
../bisonflex/bif.yy.cpp:1608:18: error: no match for 'operator=' (operand types are 'std::istream' {aka 'std::basic_istream'} and 'std::istream*' {aka 'std::basic_istream*'})
Fix it by using normal local #include statements by:
sed -i 's/<FlexLexer.h>/"FlexLexer.h"/g' *
This patch re-adds the patch to fix this to buildroot.
