Building GCC under Cygwin. Please help.

["Vivin Suresh Paliath" <computer_maniac at hotmail dot com>]

Hello,

 

This is the third time I am sending this problem in. I didn't get a response earlier. I would really appreciate any help!

 

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:

 

/build/gcc/xgcc -B/build/gcc/ -B/usr/i686-pc-cygwin32/bin/ -I/usr/i686-pc-cygwin32/include -O2 -I/srcdir/gcc-2.95.3/gcc/../winsup/include -DIN_GCC -g -O2 -I./include -g1 -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fexceptions -I. -I/srcdir/gcc-2.95.3/gcc -I/srcdir/gcc-2.95.3/gcc/config -I/srcdir/gcc-2.95.3/gcc/../include -c \

-DL${name} /srcdir/gcc-2.95.3/gcc/libgcc2.c -o ${name}.o; \

if [ $? -eq 0 ] ; then true; else exit 1; fi; \

ar rc tmplibgcc2.a ${name}.o; \

rm -f ${name}.o; \

done

I am not sure what this means. Does it mean that there is an error in the C file? This is the first time I am trying to compile gcc. Any help would be appreciated. Thanks!
