I need to install gcc-4.7-SVN onto a machine where I don't have root access.
I'd like to install with the /kurs/cpp prefix. For doing so, I configure
like
CFLAGS='-L/kurs/cpp/lib' LDFLAGS="-L/kurs/cpp/lib -Wl,-rpath,/kurs/cpp/lib"
\
./configure --prefix=/kurs/cpp --enable-languages="c++" \
--with-gmp=/kurs/cpp --with-mpfr=/kurs/cpp
--with-mpc=/kurs/cpp
It would be easier to compile gmp/mpfr/mpc as static-only
(--disable-shared) which is what gcc does if you let it build them itself.
Still I get a configure error when the new gcclib is built:

LDFLAGS is only used for stage1. Things like BOOT_LDFLAGS (or others) may
help, see the doc. The -L shouldn't be needed (you have --with-gmp),
especially in CFLAGS.
