Issues with installing Mono 2.6.7 in Mac 10.4.7

Question

I'm installing Mono 2.6.7 on a Mac 10.4.7, and running across few issues. I've solved some of them by updating few libraries via MacPort, but this one is the latest.

When I start Mono, it crashes. Any help is appreciated.

Answer 1

OS X's system libraries often contain multiple versions of standard C functions. Starting 10.5, OS X supports the Single Unix Specification. The stderror function as in BSD behaves slightly differently in SUS. So, the library has two versions, _stderror and _stderror$UNIX2003. Which to use is determined at the compile time, as described here, using C preprocessor macros.

I think the Mono binary you're using was compiled in a newer environment. You need to recompile it. If you recompile it on 10.4 machine, it should automatically use the non-UNIX2003 version and it should run fine.

By the way, seriously, update 10.4.7 to 10.4.11.

I got this resolved by installing macports, and then doing a

sudo port install mono

Which essentially downloads mono and related dependencies, and compile mono against the local libraries.
