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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
