This is a followup to my "gcc-3.2: gcc driver doesn't pick up crt0.a
from /usr/lib" message.
I have found that configure sets GCC_FOR_TARGET to the cross-compiler I
use in the root Makefile.
GCC_FOR_TARGET = i686-pc-cygwin-gcc
Then gcc/Makefile is using it to create the spec file
specs: xgcc$(exeext)
$(GCC_FOR_TARGET) -dumpspecs > tmp-specs
mv tmp-specs specs
and obviously the spec file defines:
*cross_compile:
1
which makes gcc drop /lib and /usr/lib from the 'libraries:' search path.
IMO this is wrong considering that the configure line was:
"$r/src/$gcc/configure" --build=i686-pc-linux-gnu \
--host=i686-pc-cygwin --target=i686-pc-cygwin \
--prefix=/usr --includedir=/nonexistent/include \
--enable-languages=c,c++ \
--enable-threads=posix \
--with-system-zlib \
--enable-nls \
--without-included-gettext \
--disable-version-specific-runtime-libs \
--enable-shared \
--enable-haifa \
--enable-interpreter
Can someone shed some light here? Why GCC_FOR_TARGET is not left as
defined in the gcc/Makefile?
GCC_FOR_TARGET = ./xgcc -B./ -B$(build_tooldir)/bin/ -isystem
$(build_tooldir)/include -isystem $(build_tooldir)/sys-include
TIA,

The gcc mailing list is a more appropriate place for these types of
questions. gcc at gcc dot gnu dot org.

Hello,
I am facing a gcc-3.2 configuration problem and I would like to ask your
opinion about it. I have built an i686-pc-cygwin gcc compiler on Linux
using a gcc-3.2 i686-pc-linux-gnu to i686-pc-cygwin cross compiler I
have built and installed in $HOME/cygwin.
r=$HOME/cygwin
i=$HOME/install
# Build, host, target
b=`$r/src/$binutils/config.guess`
h=i686-pc-cygwin
t=i686-pc-cygwin
#
mkdir -p "$r/src/build/$gcc" && \
cd "$r/src/build/$gcc" && \
"$r/src/$gcc/configure" --build=$b --host=$h --target=$t \
--prefix=/usr --includedir=/nonexistent/include \
--enable-languages=c,c++ \
--enable-threads=posix \
--with-system-zlib \
--enable-nls \
--without-included-gettext \
--disable-version-specific-runtime-libs \
--enable-shared \
--enable-haifa \
--enable-interpreter && \
make all && \
make install prefix="$i/$gcc/usr" && \
cd "$i/$gcc" && tar -cf "$r/$gcc.tar" *
At build time I have $HOME/i686-pc-cygwin/lib stuffed with the
i686-pc-cygwin lib files including crt0.o. It builds fine, but when I
install it on Cygwin it can't find crt0.o. /usr/lib.crt0.o is available
but gcc it doesn't even look in /usr/lib:
$ gcc -print-search-dirs
install: /usr/lib/gcc-lib/i686-pc-cygwin/3.2/
programs:
=/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/:/usr/lib/gcc/i686-pc-cygwin/3.2/:/usr/lib/gcc/i686-pc-cygwin/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/bin/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/bin/
libraries:
=/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/lib/
The stock Cygwin gcc and also the native Linux one have a libraries line
like:
install: /usr/lib/gcc-lib/i686-pc-cygwin/3.2/
programs:
=/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/:/usr/lib/gcc/i686-pc-cygwin/3.2/:/usr/lib/gcc/i686-pc-cygwin/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/bin/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/bin/
libraries:
=/usr/lib/gcc-lib/i686-pc-cygwin/3.2/:/usr/lib/gcc/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/lib/i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/lib/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../i686-pc-cygwin/3.2/:/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../:/lib/i686-pc-cygwin/3.2/:/lib/:/usr/lib/i686-pc-cygwin/3.2/:/usr/lib/
Any ideas?
Thank you,
