The Boot JDK detection # process has been developed as a response to solve a complex real-world # problem. Initially, it was simple, but it has grown as platform after # platform, idiosyncrasy after idiosyncrasy has been supported. # # The basic idea is this: # 1) You need an acceptable *) JDK to use as a Boot JDK # 2) There are several ways to locate a JDK, that are mostly platform # dependent **) # 3) You can have multiple JDKs installed # 4) If possible, configure should try to dig out an acceptable JDK # automatically, without having to resort to command-line options # # *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with # javac) and not a JRE, etc. # # **) On Windows we typically use a well-known path. # On MacOSX we typically use the tool java_home. # On Linux we typically find javac in the $PATH, and then follow a # chain of symlinks that often ends up in a real JDK. # # This leads to the code where we check in different ways to locate a # JDK, and if one is found, check if it is acceptable. If not, we print # our reasons for rejecting it (useful when debugging non-working # configure situations) and continue checking the next one. ################################################################################ # Execute the check given as argument, and verify the result # If the Boot JDK was previously found, do nothing # $1 A command line (typically autoconf macro) to execute AC_DEFUN([BOOTJDK_DO_CHECK], [ if test "x$BOOT_JDK_FOUND" = xno; then # Now execute the test $1 # If previous step claimed to have found a JDK, check it to see if it seems to be valid. if test "x$BOOT_JDK_FOUND" = xmaybe; then # Do we have a bin/java? if test ! -x "$BOOT_JDK/bin/java" && test ! -x "$BOOT_JDK/bin/java.exe"; then AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/java; ignoring]) BOOT_JDK_FOUND=no else # Do we have a bin/javac? if test ! -x "$BOOT_JDK/bin/javac" && test ! -x "$BOOT_JDK/bin/javac.exe"; then AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/javac; ignoring]) AC_MSG_NOTICE([(This might be an JRE instead of an JDK)]) BOOT_JDK_FOUND=no else # Oh, this is looking good!
