From: Jonathan McDowell Date: Thu, 14 Jul 2005 16:15:57 +0000 (+0000) Subject: Add dynamic loading of backends. X-Git-Tag: 0.3.3~20 X-Git-Url: https://the.earth.li/gitweb/?a=commitdiff_plain;h=ec6d9d2d119c9b215103c13bcc5b9b44bd24b997;p=onak.git Add dynamic loading of backends. This adds support for the dynamic loading of backends. By default we now try to build all the backends we can and then dynamically load the one the user wants. --- diff --git a/Makefile.in b/Makefile.in index dec603d..6a15a7f 100644 --- a/Makefile.in +++ b/Makefile.in @@ -3,13 +3,14 @@ # CC = @CC@ -CFLAGS += @CFLAGS@ -Wall -pedantic +CFLAGS += @CFLAGS@ -Wall -pedantic -fPIC # Uncomment to enable profiling.
