Issues compiling gdb-ve on NEC Aurora Tsubasa

[cvonelm]

I have been trying to compile GDB for the NEC Aurora platform, particularly to obtain a libbfd for use with the NEC platform.

However, I have only managed to produce a bfd for the x86 platform from the code here yet.

Could someone tell me the basic steps for compiling this repository for the NEC platform?

Sorry, it looks like we're missing the corresponding "meta" package to gdb, which contains a spec file. I hope my colleagues will upload that for the sake of completeness.

There are source rpms in the "normal" repositories, though, one of them is here:
https://sxauroratsubasa.sakura.ne.jp/repos/TSUBASA-repo_el8.6/veos/3.0.1/Source/gdb-ve-7.12.1-7.el8.src.rpm

If you unpack that, you get a spec file which should help you with the build (or rebuild the whole thing). You'll need some VE specific packages, like veos-devel.

Here are some excerpts which should help you:
Requirements for building:

BuildRequires: readline-devel >= 6.2-4
BuildRequires: ncurses-devel texinfo gettext flex bison
BuildRequires: expat-devel
BuildRequires: zlib-devel
BuildRequires: libstdc++
BuildRequires: texinfo-tex
BuildRequires: texlive-collection-latexrecommended
BuildRequires: info
BuildRequires: gzip
BuildRequires: veos-devel
%if 0%{?rhel} == 8
BuildRequires: python36-devel
%else
BuildRequires: python-devel
%endif
Requires: readline
Requires: zlib
Requires: expat
Requires: veos-libveptrace

And the configure step:

../configure                                            \
        --prefix=%{prefix}                              \
        --infodir=%{prefix}/share/info                  \
        --target=ve-nec-linux                           \
        --enable-gdb-build-warnings=,-Wno-unused        \
        --disable-nls                                   \
        --disable-tui                                   \
        --program-prefix=""                             \
        --with-expat                                    \
        --with-system-readline                          \
        --with-system-zlib                              \
        --enable-64-bit-bfd                             \
        --disable-sim                                   \
        --disable-rpath                                 \
        --sysconfdir=%{_sysconfdir}                     \
%if 0%{?rhel} == 8
        --with-python=python3.6                         \
%endif
        --with-system-gdbinit=%{_sysconfdir}/gdbinit

make %{?_smp_mflags} LDFLAGS="$LDFLAGS $FPROFILE_CFLAGS"

Unfortunately, from the sources I do not see how one would build libbfd and libiberty that are included in
https://sxauroratsubasa.sakura.ne.jp/repos/TSUBASA-repo_el8.6/veos/3.0.1/Source/gdb-ve-7.12.1-7.el8.src.rpm
or
https://sxauroratsubasa.sakura.ne.jp/repos/TSUBASA-repo_el8.6/veos/3.1.0/Source/gdb-ve-7.12.1-8.el8.src.rpm
These are also not in any of the packages.
@efocht Any hints?
