Architecture-specific symbols files can be supplied by naming them liblxc1.symbols.<arch>, for example liblxc1.symbols.sparc64. The attached liblxc1.symbols.sparc64 was created by copying liblxc1.symbols and then applying the attached symbols.diff. I think the same file could be used for liblxc1.symbols.alpha, liblxc1.symbols.m68k, liblxc1.symbols.sh4 and liblxc1.symbols.sparc64. I have verified that building lxc 4.0.11-1 against sid on sparc64 succeeds when the attached liblxc1.symbols.sparc64 is included in the debian directory.

Another approach could be to lower DPKG_GENSYMBOLS_CHECK_LEVEL to 0 on architectures where libseccomp-dev is not available. This will still log the symbol differences but without failing the build. This can be achieved by applying the attached rules.diff against debian/rules. This approach avoids having to maintain architecture-specific symbols files. I have verified that building lxc 4.0.11-1 against sid on sparc64 succeeds with the attached rules.diff applied.

Both approaches are documented at [1].

Could you please consider adopting either one of these approaches? Thanks!

For hppa, as described by Dave Anglin above, libseccomp-dev is actually available and changing the dependency from libseccomp-dev [!alpha !hppa !m68k !sh4 !sparc64] to libseccomp-dev [!alpha !m68k !sh4 !sparc64] should allow the build to succeed there.

Merci!

Tom
