调研方向

Start by reproducing the failure with the Docker command in the issue, then inspect the preprocessor condition around line 214 of missing/dtoa.c, included from missing.c. Check how the condition behaves with the reported compiler and Ruby 3.0.6. Done means the gem builds and loads successfully in that environment.

描述

Hi there; We're just trying to compile the latest release of this gem and hitting an issue:

missing/dtoa.c:214:20: error: missing binary operator before token "("

Replication command:

docker run --rm --user jenkins --env HOME=/home/jenkins rapid7/msf-ubuntu1204-x86-omnibus:2024_04 linux32 bash -lc 'mkdir -p "$HOME/.local/share/gem/ruby/3.0.0/cache" && source /home/jenkins/.rvm/scripts/rvm && rvm use 3.0.6 && gem install bigdecimal -v 4.1.3 --platform ruby --no-document && ruby -rbigdecimal -e '\''abort unless BigDecimal::VERSION == %q(4.1.3) && BigDecimal(%q(1.25)) + BigDecimal(%q(2.75)) == 4; puts %Q(bigdecimal #{BigDecimal::VERSION}: compiled and loaded)'\'''
