Merge #682: Remove Java Native Interface
642cd062bdd2d28a8a84d4cb6dedbfe435ee5869 Remove Java Native Interface (Jonas Nick) Pull request description: This was discussed in #508. The main reasons are that the existing Java Native Interface (JNI) bindings would need way more work to remain useful to Java developers but the maintainers and regular contributors of libsecp are not very familiar with Java (and evidently are motivated enough to improve the situation). We don't know who relies on these bindings with the exception of ACINQ who have their own fork at https://github.com/ACINQ/secp256k1/tree/jni-embed/src/java (@sstone). Bitcoinj can optionally use the libsecp bindings. Ideally, there would be a separate repository owned by Java developers with just the bindings. Until this exists, Java developers relying on libsecp can use ACINQs fork or an older commit of libsecp. ACKs for top commit: real-or-random: ACK 642cd062bdd2d28a8a84d4cb6dedbfe435ee5869 I read the diff real-or-random: ACK 642cd062bdd2d28a8a84d4cb6dedbfe435ee5869 I read the diff, and I verified that the diff to 7d9066a66c0f13cabb0c4f71aca30edd3494f0d5, which has been ACKed by sipa, is only the additonal removal of ax_jni_include_dir.m4 Tree-SHA512: 9e573f2b01897bd5f301707062b41de53424517b537ce0834d9049d003cfd73fa1bcc024b543256016e4c9a1126f7c7fef559b84dc4914083b5a2d0ad5e57ea8

# SYNOPSIS
|
||||
#
|
||||
# AX_JNI_INCLUDE_DIR
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# AX_JNI_INCLUDE_DIR finds include directories needed for compiling
|
||||
# programs using the JNI interface.
|
||||
#
|
||||
# JNI include directories are usually in the Java distribution. This is
|
||||
# deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
|
||||
# that order. When this macro completes, a list of directories is left in
|
||||
# the variable JNI_INCLUDE_DIRS.
|
||||
#
|
||||
# Example usage follows:
|
||||
#
|
||||
# AX_JNI_INCLUDE_DIR
|
||||
#
|
||||
# for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
|
||||
# do
|
||||
# CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
|
||||
# done
|
||||
#
|
||||
# If you want to force a specific compiler:
|
||||
#
|
||||
# - at the configure.in level, set JAVAC=yourcompiler before calling
|
||||
# AX_JNI_INCLUDE_DIR
|
||||
#
|
||||
# - at the configure level, setenv JAVAC
|
||||
#
|
||||
# Note: This macro can work with the autoconf M4 macros for Java programs.
|
||||
# This particular macro is not part of the original set of macros.
