I don't see a repo or issue tracker for riscv-softw and the error message says to report issues here, but please redirect me if there's a better place for this.

I'm getting the same error on M1 running Monterey 12.7.1:

Any pointers greatly appreciated...

I can't reproduce the error, but I do not have machine with macOS 12 currently. The error message appears to originating in rvv code, which in general, is quite recent. I suspect the issue might be that code is expecting a different C++ version. This error may not have occurred for others since their compiler's default C++ version is sufficient. The gcc code could be more compatible if it made the version expectation explicit with a compiler flag.

Thus, this might be an issue with riscv-gnu-toolchain.

[sbeamer]

This is probably the same issue of #103. Since I already commented here, I am going to keep this one open and close the other.

The same issue with Monterey 12.7.4

[74HC14]

i also have this problem
../.././gcc/gcc/config/riscv/genrvv-type-indexer.cc:120:30: error: no member named 'log2' in namespace 'std'; did you mean simply 'log2'? elmul_log2 = lmul_log2 + std::log2 (eew / sew); ^~~~~~~~~ log2
is there maybe a dirty fix by editing a file to change where log2 is referenced to? or by editing the file at /gcc/gcc/config/riscv/genrvv-etc, wherever that is. i'm probably going to have to upgrade my computer soon anyhow...

[jreyess99]

I have the same problem, is there any solution for it?

[sbeamer]

A workaround might be to use a newer compiler which has a newer default C++ version. I would try:

$> brew install gcc
$> HOMEBREW_CC=gcc-14 HOMEBREW_CXX=g++-14 brew install riscv-gnu-toolchain
