I’m afraid there isn’t much I can do about that, other than ask upstream to add MIPS support. Given the RC severity of this bug, I’ll consider the main point of the bug to be the latter part: > The RC severity is based on looking at a related question: > How did intelrdfpmath compile on new platforms like powerpc/arm/s390x > that never had any explicit support in intelrdfpmath? > > intelrdfpmath (2.0u2-2) unstable; urgency=medium > * Assume unknown architectures are “EFI2”. > > LIBRARY/float128/architecture.h: > #if defined(ct) || defined(efi2) > # undef _M_AMD64 > # define _M_AMD64 > #endif > > This builds, but the (used) definition > # define ENDIANESS little_endian > isn't correct on s390x, and neither is > # define BITS_PER_LONG 64 > on 32bit arm. Ah, I knew that would bite me some day... I’m updating intelrdfpmath to apply the architecture definitions used in libmongocrypt (see <https://github.com/mongodb/libmongocrypt/blob/master/cmake/IntelDFP.cmake>): armel/armhf are assumed to behave like i386 (I haven’t checked whether that makes sense), arm64/ppc64el/riscv64 are assumed to behave like amd64, and s390x is supported explicitly. If you want to track the unsupported architectures, please open a new bug. As far as I can tell, even if libmongocrypt were built in Debian using its embedded copy of intelrdfpmath, it would fail on the same architectures. Regards, Stephen
