Available for test: gcc-3.2-1, gcc-mingw-3.2-20020817-1, gcc2-2.95.3-10

[Christopher Faylor]

I've updated gcc to version 3.2 and made it available for testing,
along with all of the pieces from the gcc mingw release (thanks, Danny)
required for the -mno-cygwin switch.  This version is based on the
just released 3.2 version of gcc plus changes in the gcc cygwin/mingw
branch.

I've verified that this version builds cygwin ok and passes Chuck Wilson's
minimal tests.

There is also a gcc2 update, also available only for testing.  This
version has fastcall support from Danny's mingw release and includes
some tweaks that should allow me to eventually reintroduce the alignment
changes in binutils which allow java to work better.

The easiest way to install these packages is to click on the "Exp" button
in the Select packages screen when running setup.exe.

Reports to cygwin@cygwin.com, please.

After waiting a suitable amount of time for the packages to show up on
mirrors, of course.

[gcc 3.2]: undefined symbols when compiling cygwin dll.

[Nicholas Wourms]

Hi,

I just wiped my cygwin install and started fresh with a new install
based on gcc-3.2.  As usual, I installed everything.  I then
proceeded to attempt compiling the cygwin dll (from cvs sources)
using the following flags:

CXXFLAGS="-I/usr/include/c++/3.2" ../src/configure
--prefix=/usr/src/cygwin-src/build/../install

Before I continue, let me state that the tree wasn't broken earlier
today.  Also, no commits have been made on the cygdaemon-branch since
then.  That being said, the build process craps out when it is trying
to link all the object files for the dll.  Gcc states:

/usr/lib/gcc-lib/i686-pc-cygwin/3.2/libgcc.a(w32-shared-ptr.o)(.text+0x60):
undefined reference to `_FindAtomA@4'
/usr/lib/gcc-lib/i686-pc-cygwin/3.2/libgcc.a(w32-shared-ptr.o)(.text+0x131):
undefined reference to `_AddAtomA@4'
/usr/lib/gcc-lib/i686-pc-cygwin/3.2/libgcc.a(w32-shared-ptr.o)(.text+0x18e):
undefined reference to `_GetAtomNameA@12'

I'm not sure if this is a bug or me missing something, but I thought
I'd report it anyway.  Truth be told, I'm not terribly familiar with
the gcc sources, but I'll poke around to see what turns up.  Also,
note that I have verified that I have the proper packages necessary
for gcc-3.2 installed.

Cheers,
Nicholas

Ok, I just remembered that those symbols are from kernel32.dll.  So,
I went back and modified the arguments passed by make to compile the
cygwin dll, appending "-lkernel32" to the end of the line.  Executing
the new command does, indeed, resolve the problem.  So I guess one
would need to modify Makefile.in to link the dll with -lkernel32
appended to the list of arguments.

Cheers,
Nicholas

This was changed in CVS prior to releasing gcc 3.2.

I guess Conrad hasn't merged these changes from HEAD yet =).  Sorry,
I guess I should have checked the commits list a little more
carefully.

Not just java, we're waiting on these binutils so we can use the SSE
extensions for gcc that need to have 128-bit stack alignment working
properly.  At least we hope that's the only problem :-(

Any chance of a pre-release version to test?  We don't use gcc-2 anyway.

Dylan,

I'm sure Chris will release them when he thinks it is appropriate. 
However, you need not wait, for the sources are only a few dozen
keystrokes away...

1)cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/src login
>>>password: anoncvs
2)cvs -z9 -d:pserver:anoncvs@sources.redhat.com:/cvs/src co binutils
3)mkdir build
4)cd build
5)../src/configure --prefix=../install
6)make; make install
7)cd ../install; tar -jcvf /binutils-20020826-1.tar.bz2 *
8)copy the tarball to {temp dir}/binutils and point setup.exe there
to install...

Eight easy steps to get a binutils prerelease.  Easy as Dell, easy as
apple pie =).

Cheers,
Nicholas

Oops!  I was being a bit slow there: it's all nice and up-to-date
now.

Thanks, that's really helpful, I wasn't sure that the cvs development
version of binutils was useable unmodified on cygwin.  I seem to remember
trying to build binutils some time this year and it didn't work, but then
again, now a lot of the other packages have already been updated in cygwin
its probably ok.

this step didn't work - required --prefix=/home/dylan/gnu/binutils-install
(or whatever directory you want but it needed an absolute path)

Did this... it installed into the cygwin root directory rather than into
/usr, ie. I now have "man" and "i686-pc-cygwin/bin" etc all relative to
root.  This doesn't seem right as my paths don't look in there, is there
some other way I am meant to have configured it?

Almost there though.

Well, actually it isn't working like I thought it would be (by now). 
However, checkout the reply to "binutils (cvs) problems" I just
posted.  Apparently there is an issue which hasn't been fixed in HEAD
yet.  However there is a link to a thread which contains the fix.

Cheers,
Nicholas
