From 5440bc8ef38c925fa824ae72b6c7ad2f21cbda6e Mon Sep 17 00:00:00 2001 From: Jarkko Hietaniemi Date: Fri, 15 Jun 2001 00:15:52 +0000 Subject: The first steps towards cross-compilation. Abstract execution of compiled test executables with $run, and abstract transfer of files with $to and $from. Under cross-compilation the $run, $to, and $from will point to appropriate wrapper scripts, by default ssh and scp, but also rsh, rcp, and cp are supported. If not cross-compiling, they will be set to '', ':', and ':', respectively. With these patches I was able to get Configure for iPAQ ARM Linux on an Intel Linux about 95% right (only a few tests failed to execute or they produced incorrect results), and I was able to compile a functional miniperl. The symbol crosscompile renamed to be usecrosscompile, the corresponding C symbol from CROSSCOMPILE to USE_CROSS_COMPILE. p4raw-id: //depot/perl@10592 --- Porting/Glossary | 31 ++++++++++++++++++++++++++----- 1 file changed, 26 insertions(+), 5 deletions(-) (limited to 'Porting/Glossary') diff --git a/Porting/Glossary b/Porting/Glossary index 7a5e580b73..26e6e4ca92 100644 --- a/Porting/Glossary +++ b/Porting/Glossary @@ -328,11 +328,6 @@ cppsymbols (Cppsym.U): not in this list, see ccsymbols and cppccsymbols.
