When using GCJ to link a Java program, you must use the --main= option to indicate the class that has the desired main method. This is because every Java class can have a main method, thus you have to tell gcj which one to use. <<Anchor(comp_src)>>Can GCJ only handle source code? GCJ will compile both source (.java) and bytecode (.class) files.
Jan 22, 2022 · Thanks for your post in Microsoft Community. It sounds like your app download keeps defaulting to C drive instead of D. In order to provide you with better assistance, I would like to understand your situation better: 1. What software do you use to download this problem? 2. Is it automatically moved to C drive after downloading to D drive?

GCJ, a radically traditional (*) Free Software implementation of the Java language, has been part of GCC since the 3.0 release in June 2001. Currently at version 3.2.1, it is supported on GNU/Linux on Pentium, Itanium, Alpha, PowerPC and AMD Hammer, FreeBSD on Pentium, Solaris on SPARC and more. Support for Windows using MinGWis also available. It ...
GNU/Linux
GCC is bundled with most Linux distributions. To install GCJ on a Red Hat Linux 8.0 system, simply run 1. rpm -i gcc-java-3.2-7.i386.rpm 2. rpm -i libgcj-3.2-7.i386.rpm 3. rpm -i libgcj-devel-3.2-7.i386.rpm
Windows
Windows users need to visit the MinGW Downloadpage and get the following two files: 1. MinGW Version 20120426 2. Java: gcj-3.2-20021210-1.tar.gz and install both into a common directory (C:\MinGWwill work fine.)
Other Platforms
Users of other platforms may get binary distributions of GCC from their favorite download centers.
For the rest of the article, I will use Red Hat Linux 8.0 as my platform. The differences between platforms are mostly limited to filename extensions. GCJ has two parts: the compiler and the runtime support library. The compiler includes these commands: gcj the GCJ compiler gcjh generates header files from Java class files jcf-dump prints informati...
The -sharedswitch tells gcj to link into a shared library. Assume the following sources: we can compile A.java into a shared library libA.so, and compile B.java into an executable B that is linked against libA.so: We have to put libA.so temporarily into the LD_LIBRARY_PATH before executing B:
Support for GCJ has been added to the GNU Debugger GDB. The full power of GDB can be used with Java programs. To make debugging symbols available to GDB, we need the -g switch on the gcjcommand line: In gdb, run starts the executable, break sets break points, step, next, cont controls flow of execution, print, displayprints values of variables. The...
GCJ is sufficiently different from other Java implementations that we need to pay attention to how things are done with it.
In addition to standard JNI, GCJ provides an alternative Compiled Native Interface (CNI, originally Cygnus Native Interface) to C/C++ code that takes full advantage of the fact that GCJ implements Java as basically a subset of C++. The CNI mapping provides C++ classes for primitive Java types, a set of functions to work with Java strings and arrays...
Since GCJ is a free software implementation of Java, many free software Java packages have been ported to work with GCJ. The rhugproject provides a collection of such ports. Notable entries include Ant, Log4j, JUnit, Rhino, Xalan-Java, Xerces2-J. As I am writing this article, reports surfaced on the Internet that GCJ can now run Eclipse, the Java b...
GCJ is a capable, wide spread, free implementation of the Java platform. It offers some unique characteristics that make it viable to use the Java programming language in situations where using the J2SE SDK is not feasible. Obvious advantages of GCJ over the J2SE SDK include faster startup time, smaller memory footprint, shared memory between diffe...
The GCJ home page http://gcc.gnu.org/GCJ documentation page http://gnu.ist.utl.pt/software/gcc/java/docs.htmlThe GCJ FAQ http://gcc.gnu.org/java/faq.htmlThe GCJ status page http://gcc.gnu.org/java/status.htmlThe May 2006 issue of Linux Journal contains the article "Embedded Java with GCJ" by Gene Sally. June 6, 2006 RMS approved the plan to use the Eclipse compiler as the new gcj front end. Work is being done on the gcj-eclipse branch; it can already build libgcj. This project will allow us to ship a 1.5 compiler in the relatively near future.
