Cygwin port

Cygwin port

[Jerome Marc]

Hello,

I successfully built the libjava library. But there
are still some trouble.
While compiling jv-convert, I've got the following
errors :

ranlib .libs/libgcj.a
rm -fr .libs/libgcj.lax

(cd .libs && rm -f libgcj.la && ln -s ../libgcj.la

and so on... Any idea ?

They're old but they are still accurate.  Nothing that would affect
the problem has changed.

I would like to do the stuff but I think many people
want this too.

I just want to have some ideas here about case
sensitivty problems. All the posts about this subject
seem to be old.

My gcc configuation is :
configure --enable-libgcj
--enable-languages=c,c++,java

As far as I know nobody has tried this.

What exactly happens when linking the library?
Also, how do you configure gcc?

I don't know of any in libjava.  The problem is that the compiler
itself gets confused by the case insensitivity.  The Gnu.java build
problem you saw is the symptom.

There's a bunch of discussion of the bug in the mailing list archives.
Now that libgcj has mostly been ported to Windows, I'd think it
wouldn't be too hard for someone (you :-) to fix this gcj bug.

I read that libjava cannot be built with cygwin because of Windows case
insensitive filesystems. I would like to know if anyone tried the
environment setting : CYGWIN=check_case:strict

With this setting, I can compile whole java classes successfully but found
any trouble while linking the library. Whithout this setting, the building
process stops while compiling Gnu.java.

I just wonder what are the case sensitivity issues whith libjava.

I just wonder what are the case sensitivity issues whith libjava.
