The Boot JDK detection 2850476Speter# process has been developed as a response to solve a complex real-world 293199Sjkh# problem. Initially, it was simple, but it has grown as platform after 30163798Skeramida# platform, idiosyncracy after idiosyncracy has been supported. 3153200Sphantom# 3279538Sru# The basic idea is this: 333199Sjkh# 1) You need an acceptable *) JDK to use as a Boot JDK 343199Sjkh# 2) There are several ways to locate a JDK, that are mostly platform 3589225Sru# dependent **) 363199Sjkh# 3) You can have multiple JDKs installed 3784877Syokota# 4) If possible, configure should try to dig out an acceptable JDK 3884877Syokota# automatically, without having to resort to command-line options 3984877Syokota# 4084877Syokota# *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with 4184877Syokota# javac) and not a JRE, etc. 4284877Syokota# 4384877Syokota# **) On Windows we typically use a well-known path. 4484877Syokota# On MacOSX we typically use the tool java_home. 4588028Sjoerg# On Linux we typically find javac in the $PATH, and then follow a 4684877Syokota# chain of symlinks that often ends up in a real JDK. 4784877Syokota# 4888028Sjoerg# This leads to the code where we check in different ways to locate a 4984877Syokota# JDK, and if one is found, check if it is acceptable. If not, we print 5084877Syokota# our reasons for rejecting it (useful when debugging non-working 5188028Sjoerg# configure situations) and continue checking the next one. 523199Sjkh######################################################################## 5388028Sjoerg 5489225Sru# Execute the check given as argument, and verify the result 5589225Sru# If the Boot JDK was previously found, do nothing 5688028Sjoerg# $1 A command line (typically autoconf macro) to execute 5788028SjoergAC_DEFUN([BOOTJDK_DO_CHECK], 5830575Sjoerg[ 5989225Sru if test "x$BOOT_JDK_FOUND" = xno; then 6089225Sru # Now execute the test 6188028Sjoerg $1 62132219Snjl 63132219Snjl # If previous step claimed to have found a JDK, check it to see if it seems to be valid. 6489225Sru if test "x$BOOT_JDK_FOUND" = xmaybe; then 6588028Sjoerg # Do we have a bin/java? 6689225Sru if test ! -x "$BOOT_JDK/bin/java"; then 6789225Sru AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/java; ignoring]) 6888028Sjoerg BOOT_JDK_FOUND=no 6988028Sjoerg else 7088028Sjoerg # Do we have a bin/javac? 7188028Sjoerg if test ! -x "$BOOT_JDK/bin/javac"; then 7288028Sjoerg AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/javac; ignoring]) 7389225Sru AC_MSG_NOTICE([(This might be an JRE instead of an JDK)]) 7489225Sru BOOT_JDK_FOUND=no 7588028Sjoerg else 7688028Sjoerg # Oh, this is looking good!
