The issue has been reported +to the Binutils mailing list but Alan Modra recommend to bundle +libbfd library sources into each projects using it [2]. That's +because the API is not stable over the time without any backward +compatibility guaranties. + +On the other hand, the elf2flt tools needs to support modified +version of binutils for specific arch/target [3]. + +Add two tests in the configure script to detect this API change +in order to support binutils < 2.34 and binutils >= 2.34. + +Upstream status: [4] + +[1] https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=fd3619828e94a24a92cddec42cbc0ab33352eeb4 +[2] https://sourceware.org/ml/binutils/2020-02/msg00044.html +[3] https://github.com/uclinux-dev/elf2flt/issues/14 +[4] https://github.com/uclinux-dev/elf2flt/pull/15 + +Signed-off-by: Romain Naour +--- + configure.ac | 16 +++++++++++ + elf2flt.c | 81 +++++++++++++++++++++++++++++----------------------- + 2 files changed, 61 insertions(+), 36 deletions(-) + +diff --git a/configure.ac b/configure.ac +index b7db2cb..fdc0876 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -229,6 +229,22 @@ AC_CHECK_FUNCS([ \ + strsignal \ + ]) + ++dnl Various bfd section macros and functions like bfd_section_size() have been ++dnl modified starting with binutils >= 2.34. ++dnl Check if the prototypes take a bfd argument. ++if test "$binutils_build_dir" != "NONE";
