From f8dcf03416bec49ee4ba7cc1615f61fa5e5419d7 Mon Sep 17 00:00:00 2001 From: David Reiss Date: Sat, 23 Feb 2008 22:07:39 +0000 Subject: Add automake support for building the Java library. If java, javac, and ant are all available, the Java library will be built as part of the standard make target. git-svn-id: https://svn.apache.org/repos/asf/incubator/thrift/trunk@665494 13f79535-47bb-0310-9956-ffa450edef68 --- aclocal/ax_java.m4 | 277 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 277 insertions(+) create mode 100644 aclocal/ax_java.m4 (limited to 'aclocal') diff --git a/aclocal/ax_java.m4 b/aclocal/ax_java.m4 new file mode 100644 index 000000000..301586c2e --- /dev/null +++ b/aclocal/ax_java.m4 @@ -0,0 +1,277 @@ +dnl +dnl The following commonly available Java macros converted to AX prefix +dnl in support of proper thrift/autoconf extension naming rules +dnl + +divert(-1) + +autoconf M4 macros for Java programs +Copyright Stephane Bortzmeyer , 1999 +Released under the GPL licence + +A sample configure.in is at the end of this file.
