The Boot JDK detection 28# process has been developed as a response to solve a complex real-world 29# problem. Initially, it was simple, but it has grown as platform after 30# platform, idiosyncracy after idiosyncracy has been supported. 31# 32# The basic idea is this: 33# 1) You need an acceptable *) JDK to use as a Boot JDK 34# 2) There are several ways to locate a JDK, that are mostly platform 35# dependent **) 36# 3) You can have multiple JDKs installed 37# 4) If possible, configure should try to dig out an acceptable JDK 38# automatically, without having to resort to command-line options 39# 40# *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with 41# javac) and not a JRE, etc. 42# 43# **) On Windows we typically use a well-known path. 44# On MacOSX we typically use the tool java_home. 45# On Linux we typically find javac in the $PATH, and then follow a 46# chain of symlinks that often ends up in a real JDK. 47# 48# This leads to the code where we check in different ways to locate a 49# JDK, and if one is found, check if it is acceptable. If not, we print 50# our reasons for rejecting it (useful when debugging non-working 51# configure situations) and continue checking the next one. 52######################################################################## 53 54# Execute the check given as argument, and verify the result 55# If the Boot JDK was previously found, do nothing 56# $1 A command line (typically autoconf macro) to execute 57AC_DEFUN([BOOTJDK_DO_CHECK], 58[ 59 if test "x$BOOT_JDK_FOUND" = xno; then 60 # Now execute the test 61 $1 62 63 # If previous step claimed to have found a JDK, check it to see if it seems to be valid. 64 if test "x$BOOT_JDK_FOUND" = xmaybe; then 65 # Do we have a bin/java? 66 if test ! -x "$BOOT_JDK/bin/java"; then 67 AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/java; ignoring]) 68 BOOT_JDK_FOUND=no 69 else 70 # Do we have a bin/javac? 71 if test ! -x "$BOOT_JDK/bin/javac"; then 72 AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/javac; ignoring]) 73 AC_MSG_NOTICE([(This might be an JRE instead of an JDK)]) 74 BOOT_JDK_FOUND=no 75 else 76 # Oh, this is looking good!
