Re: How to build GCJ/GDC ?

[Игорь Пашев <pashev.igor@gmail.com>]

Dmitrijs, thanks for you answer :-)

I've already built GCC from VCS with some non-trivial changes and bugs (#653255)

(I'm building on a Solaris based system, with all linker, libs, fixincludes and GCC specs hell ;-)

I just wonder how to build GCJ from the same VCS (as it mentioned via source package page)

The gcc/gcj/ada/etc packaging is rather interesting. The VCS URL should
point to an svn repository which, after updating debian/changelog and
debian/control can build a few source packages for bootstrapping the gcc
toolchain, including the gcj.

If you just want to rebuild gcj, use apt-get source gcj-4.7
If you want to contribute to gcj packaging, prepare to learn a lot of
funky Makefile magic of the whole gcc packaging (cc is 'compiler
collection' which includes the gcj compiler)

There should be a README.source in the repository or similar explaining
a little bit how that packaging machinery works.

It is not a trivial package by any means.
