With bootgen xilinx_v2025.1, the local FlexLexer.h file is not in the same
directory as the cpp files including it, so the previous patch used to solve
the issue below needs to be updated to find the local FlexLexer.h which is in
the win_include directory of bootgen version xilinx_v2025.1.
See upstream commit [1].
So this patch corrects the path for including the local FlexLexer.h header for
fixing the below issue.
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*'})
This build failure can also happen if the host-flex Buildroot package
is built before host-bootgen.
The failure can be reproduced, in the Buildroot docker reference image
with the commands:
utils/docker-run
make versal_vck190_defconfig
make host-flex host-bootgen
Fix it by using normal local #include statements by:
sed -i 's/<FlexLexer.h>/"../win_include/FlexLexer.h"/g' *

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
