Override ExtUtils::MakeMaker

roperl has asked for the wisdom of the Perl Monks concerning the following question:

Trying to compile the MQSeries module using recently compiled perl Seems to complain about my arch and compiler not matching Use is there a way to override this with compiler=cc and arch=sun4-solaris-64int

/opt/perl/bin/perl Makefile.PL

Hi, See ExtUtils::FakeConfig as a means to override Config I find it much simpler to install my own perl, no Config editing at all :)	[reply]

cool thanks I'll check it out I got it to compile without having to change MakeMaker options The issue was linking the object files was giving me this error for every symbol `ld: fatal: symbol 'MQFIELD_STR' is multiply-defined: (file MQSeries.o type=FUNC; file constants.o type=FUNC);` [download] I added this to the Makefile for the LD variable `LD = /opt/solarisstudio12.3/bin/cc --allow-multiple-definition` [download] This allows for the multiply-defined symbols.
