When building perl, the following used to work: echo 'use Test;' > try.t ./perl -Ilib utils/prove try.t It now (bleadperl@34087) fails with try......Can't locate Test.pm in @INC where @INC contains the locations where perl will be installed. But if perl has not yet been installed, then Test.pm can't be found. In perl-5.8.8, it was sufficient to pass -Ilib to ./perl. In 5.10.x, it is apparently necessary to do ./perl -Ilib utils/prove -Ilib try.t That's right: -Ilib must be specified twice. Without the first one, perl complains 'Can't locate strict.pm'. I don't know how, why, or when utils/prove loses track of the ./lib directory. -- Andy Dougherty doughera@lafayette.edu

It does not "lose track of" the @INC from the parent process. TAP::Harness *does* introduce a separation between "options passed to the perl which runs prove" and "options passed to the perl which runs tests" -- this distinction is by design. Assuming that the core's "util/prove" is a "stock" copy from TAP::Harness, it should stay this way. If more convenience is desired for testing ("with" and "of") a non-installed perl, a thin wrapper (or PERL5LIB, etc) should be used to set the @INC on both sides of prove. --Eric -- "You can't win.
