Ignores -Wattributes for GCC 7 to mask compiler bug. #79
Conversation

Travis-ci pipeline looks like it failed because the build system couldn't find a public key needed by clang W: GPG error: http://apt.llvm.org/precise llvm-toolchain-precise-3.5 InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 15CF4D18AF4F7421 Appveyor failed for something similar.: make: fork: Resource temporarily unavailable |

Thanks! I'm happy to merge this as is, but I have a question. Why is the upper bound 7.4? Looking at the bug you linked, it appears to still be unresolved. |

I was looking around for similar complaints and found that a couple users
of Eigen3 couldn't reproduce the issue on gcc 7.4 on Ubuntu. I did not
test this myself, but will investigate further later tonight.

Thanks for the info. If it ends up being too much trouble, we can merge this as is. We can always widen the constraint later, or adjust it otherwise. I don't have time to fix the CI at the moment, but the Linux CI setup seems to have broken entirely due to clang repos :/ |
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89325 This bug produces massive amounts of spurious warnings and is present in the version of g++ currently available in RHEL devtoolset-7 and devtoolset-8.

So this GCC bug still exists in devtoolset-8, I made the version where this warning is ignored open-ended since it appears to not be fixed at this time. |

Thank you! |
