Thanks for confirming your setup is working. I've checked my linker script and it does have the ARM.exidx and ARM.extab sections. I have to assume this is due to some libcxxabi/libgcc issue, but who knows. I'm open to suggestions. On Wed, Jan 13, 2021 at 1:59 AM Xiang Xiao wrote: > On Wed, Jan

Is NuttX’ buildroot been adopted into Apache along with NuttX? I looked for it, but couldn’t find it. I have a few updates to push (gcc 8.4, 9, 10). I’d really like to share these… No.  It can't come into the Apache repository because it is GPL (at least not without some special considera

Hi Anthony, Since Xiang already added support for NuttX on libcxx mainstream: https://reviews.llvm.org/D88718?id=303700 I think it is time to phase out my libcxx repository and we will stick to libcxx mainline. Do you agree on that? BR, Alan On 1/9/21, Anthony Merlino wrote: > Thanks for the

Thanks for the info Xiang! I was on the right track but it is good to have some affirmation that I'm not missing something. The issue with the Arm maintained toolchain, as Greg has warned many times, is its use of newlib. Are you doing anything to ensure the wrong math library is not used? I will

Hey all, Would someone be willing to share their experience with libcxx and their toolchain? I've now caught up to the tip of master, which now downloads and builds libcxx for me instead of using Alan's modified version. I am facing an issue I've faced before, and would really love to properly un
