Hello,
I am trying to compile gcc on cygwin under 64bit win7
To configure gcc, I use the following command:
/var/tmp/builds/crossgcc/src/gcc-4.7.2/configure \
--prefix=/usr/local/crossgcc \
--with-gmp=/usr/x86_64-pc-cygwin/sys-root/usr \
--with-mpc=/usr/x86_64-pc-cygwin/sys-root/usr \
--with-mpfr=/usr/x86_64-pc-cygwin/sys-root/usr \
--enable-install-libbfd \
--enable-languages=c \
--with-gnu-ld \
--with-gnu-as \
--with-newlib \
--enable-commonbfdlib \
--enable-multilib \
--enable-interwork \
--disable-libssp \
--nfp \
--gas \
-v \
--target=arm-none-eabi \
--with-cpu=cortex-m3 \
--with-tune=cortex-m3 \
--with-mode=thumb \
--with-float=soft \
--disable-nls \
--without-headers
But configure complains that it can't find gmp, mpc and mpfr. Here is the
relevant part of the config.log file. Any ideas? The whole cponfig.log is
appended at the end of this mail.
cygwin native installations of those tools won't help with a non-cygwin
target.
Maybe this would be more suitable for gcc-help. In particular, you
might give attention to the download-prerequisites.
