In this case, the required 50 target_version is determined from the found JVM (see javaversion.h). 51 Specifying target_version is useful when building a library (.jar) that is 52 useful outside the given package. Passing target_version = NULL is useful 53 when building an application. 54 It is unreasonable to ask for: 55 - target_version < 1.4 with source_version >= 1.4, or 56 - target_version < 1.5 with source_version >= 1.5, or 57 - target_version < 1.6 with source_version >= 1.6, or 58 - target_version < 1.7 with source_version >= 1.7, or 59 - target_version < 1.8 with source_version >= 1.8, or 60 - target_version < 9 with source_version >= 9, or 61 - target_version < 10 with source_version >= 10, or 62 - target_version < 11 with source_version >= 11, 63 because even Sun's/Oracle's javac doesn't support these combinations. 64 It is redundant to ask for a target_version > source_version, since the 65 smaller target_version = source_version will also always work and newer JVMs 66 support the older target_versions too. Except for the cases 67 - target_version = 1.4, source_version = 1.3, which allows gcj versions 3.0 68 to 3.2 to be used, 69 - target-version = 1.6, source-version = 1.5, which allows gcj versions 70 >= 4.3 to be used. 71 72 directory is the target directory. The .class file for class X.Y.Z is 73 written at directory/X/Y/Z.class. If directory is NULL, the .class 74 file is written in the source's directory. 75 use_minimal_classpath = true means to ignore the user's CLASSPATH and 76 use a minimal one. This is likely to reduce possible problems if the 77 user's CLASSPATH contains garbage or a classes.zip file of the wrong 78 Java version. 79 If verbose, the command to be executed will be printed. 80 Return false if OK, true on error. */ 81 extern bool compile_java_class (const char * const *java_sources, 82 unsigned int java_sources_count, 83 const char * const *classpaths, 84 unsigned int classpaths_count, 85 const char *source_version, 86 const char *target_version, 87 const char *directory, 88 bool optimize, bool debug, 89 bool use_minimal_classpath, 90 bool verbose); 91 92 #endif /* _JAVACOMP_H */ 93
