Just spent hours battling with Ruby's official Git repository! Even when using the latest 3.4.2 tag and meticulously following the official documentation's compilation steps, the build mysteriously fails. Turns out running ./autogen.sh before ./configure isn't enough - the system still throws an error complaining that tool/config.sub is nowhere to be found during configuration. The irony? Switching to the official pre-packaged .tar.gz source solves everything instantly because it already includes all the necessary files like tool/config.sub. Such a head-scratching issue that's not mentioned anywhere in the docs! Anyone else stumbled upon this frustrating gotcha? #Ruby #CompilationIssues #DeveloperProblems #GitRepository #SoftwareDevelopment #CodingChallenges
