<title>Introduction to GCC-Java</title>

<para>
|
|
See the introduction to the Java language and system at
|
|
<xref linkend="java"/>. The GNU Compiler Collection (GCC) contains
|
|
a Java compiler to native code. Together with the
|
|
<application>ecj</application> Java compiler from Eclipse (to bytecode),
|
|
it provides a way to build an acceptable JVM from source. However, since
|
|
the release of <application>OpenJDK</application>, the development
|
|
of GCC-Java has almost stopped, and the built JVM is an old version,
|
|
which cannot be used for building <xref linkend="openjdk"/>.

Using the instructions on this page will have the effect that

the C and C++ compiler and libraries will be reinstalled, overwriting
|

the ones on your system. This may lead to some issues. Please read the

note and caution on the <xref linkend="gcc"/> page.

The instructions below assume that the C and C++ compilers have

the same version as the one you are installing, so that a

<quote>bootstrap</quote> is not necessary. If you are upgrading

If you have installed additional packages such as

<application>Valgrind</application> and <application>GDB</application>,
|

the <application>GCC</application> part of the testsuite will run more
|
|
tests than in LFS. Some of those will report FAIL and others XPASS
|

(pass when expected to FAIL). To run the tests, issue:

The tests are very long, and the results may be hard to find in the

|
ones you install.

If the package is built by a user other than root, the ownership of the
