Description Frank Ch. Eigler 2021-08-05 15:11:32 UTC

There are some reports that debuginfod client and/or server parts of elfutils may not build correctly when configured in a cross-arch mode, so people are advised to disable it:

https://www.linuxfromscratch.org/~thomas/multilib/chapter08/libelf.html

% CC="gcc -m32" ./configure \
    --host=i686-pc-linux-gnu \
    --prefix=/usr            \
    --libdir=/usr/lib32      \
    --disable-debuginfod     \
    --enable-libdebuginfod=dummy

This sort of build should also work and/or be automagically disabled, rather than require the manual configury flagging.

Comment 1 erico.erc+sourcewarebugzilla 2021-08-05 17:20:22 UTC

They suggest the same settings for native compilation:

% ./configure --prefix=/usr                \
            --disable-debuginfod         \
            --enable-libdebuginfod=dummy

I think this is just to simplify the bootstrap path, since otherwise elfutils requires a lot of dependencies.

I haven't noticed any issues when cross compiling.

I can confirm that on x86_64 fedora, with all i386 devel packages installed the following configure/build works and passes all tests:

CC="gcc -m32" CXX="g++ -m32" ./configure --host=i686-pc-linux-gnu --enable-debuginfod && make -j8 && make check -j8
