Building gcc under cygwin

Building gcc under cygwin

[Vivin Paliath]

I am having problems building GCC under Cygwin.

I followed all the instructions, but it fails when it tries to make the 
native compiler (make bootstrap).

My toplevel directory is /usr. with-ld and with-as are set to 
/usr/i686-pc-cygwin/bin . It runs the make bootstrap for a while and then it 
fails with this error:

xgcc: installation error '/usr/i686-pc-cygwin/bin' no such file or directory

Do you have step by step instructions for building under Cygwin? Are there 
any quirks that I need to know about? Maybe I'm setting my paths up wrong or 
something... I haven't done much of this stuff before. I just want to get 
gcc working so that I can use gcj... (I tried installing libgcj and gcj but 
that gave even uglier errors...)

Thanks!

with-ld  and with-as expect program names, not directory names.

I'm having problems building gcc under cygwin. I 
was informed that Cygwin has gcc-2.95.2-6 and so it isn't necessary to do a 
'make bootstrap'. I did a normal make, but I am still not able to build it. This 
is what I have done:
 
my gcc source is in /srcdir/gcc-2.95.3
my build directory is /build
 
export 
MAKE_MODE=UNIX /srcdir/gcc-2.95.3/configure --prefix=/usr --with-gnu-as 
--with-gnu-ld --enable-threads=posix 2>&1 | tee configure.out make -w 
all-gcc install-gcc LANGUAGES="c c++ java" 2>&1 | tee 
make.out
 
The make fails with the following error 
message:

Hi Vivin,
Ok, then I hope you
can help me with my original problem!
 
I wanted to install GCJ originally, but the
library (libgcj) comes separately and is a pain to install. GCC has
everything in it, GCJ and Libgcj so I thought I would install that. But
this is where I am running into the problem.
 
I am doing this the first time! So how do I do
a normal build without bootstrap? Do I still have to run
configure?
You must configure the build tree, yes.
What I suggest you _try_ (and I haven't tested this) is (assuming your
gcc sources are in /usr/src/gcc):

mkdir /tmp/build/gcc
cd /tmp/build/gcc
export MAKE_MODE=UNIX
/usr/src/gcc/configure  --prefix=/tools --with-gnu-as --with-gnu-ld
2>&1 | tee configure.out

Look carefully at the start of the output, it will say "This
configuration is not supported in the following directories: ...." -
if it talks about gcj there then gcj isn't supported in cygwin.

If the configure worked, then
make -w all-gcc install-gcc LANGUAGES="c c++ java" 2>&1
| tee make.out

and hopefully it will work.

Hello Vivin,

I am running into
problems building GCC under cygwin.
Is there something wrong with the way I have
set up paths or something?
I may have misunderstood the situation, but you shouldn't need to do a
make bootstrap, because cygwin comes with gcc 2.96.2 (or something like
that). So you can do a "normal" non-bootstrap build, which
might work for you.

Also, if you're building under Windows 95/98/Me - don't. It won't work
properly. You need Windows Nt 4.x or 5.x (2000).

95% of problems in cygwin stem from line-termination issues, by the
way...

I am running into problems building GCC under 
cygwin.
 
I ran the configure like this:
 
gcc/configure --prefix=/usr 
--with-as=/usr/i686-pc-cygwin/bin/as.exe 
--with-ld=/usr/i686-pc-cygwin/bin/ld.exe --enable-threads
 
It configured and everything, but when I run the 
make bootstrap, it runs for a while and then fails with this 
error:
 
gcc -c  -DIN_GCC     
-g  -DHAVE_CONFIG_H    -I. -I../gcc/gcc 
-I../gcc/gcc/config  -I../gcc/gcc/../include

Is there something wrong with the way I have set up 
paths or something?
 
Thanks!
