gcc 4.5 build on mingw

[Jim Hauxwell]

Hi,

Has anyone successfully built gcc4.5 under mingw and would like to share
their configure options?

I took some from a post to build 4.1, but they don't seem to work

../gcc4.5-20091022/configure --prefix= --host=mingw32 --target=mingw32
--program-prefix="" --with-as=/mingw/bin/as.exe
--with-ld=/mingw/bin/ld.exe --with-gcc --with-gnu-ld --with-gnu-as
--with-gmp=/local --with-mpfr=/local --enable-threads --disable-nls
--enable-languages=c,c++ --disable-win32-registry --disable-shared
--without-x --enable-bootstrap

make CFLAGS="-O2 -fomit-frame-pointer" CXXFLAGS="-mthreads
-fno-omit-frame-pointer -O2" LDFLAGS="-s -Wl,--stack=0x800000" bootstrap2


fails with missing mingw32-ar initially.  If I copy ar.exe to
mingw32-ar.exe and try again it gets further but complains about missing
headers.

If I still had any hair left, I'd be pulling it out by now!

Cheers

Jim

Hi,

I think its because you forgot to set "--prefix=" properly.

OK, so I added the prefix

../gcc4.5-20091022/configure --prefix=/mingw --host=mingw32
--target=mingw32 --program-prefix="" --with-as=/mingw/bin/as.exe
--with-ld=/mingw/bin/ld.exe --with-gcc --with-gnu-ld --with-gnu-as
--with-gmp=/local --with-mpfr=/local --enable-threads --disable-nls
--enable-languages=c,c++ --disable-win32-registry --disable-shared
--without-x --enable-bootstrap


make CFLAGS="-O2 -fomit-frame-pointer" CXXFLAGS="-mthreads
-fno-omit-frame-pointer -O2" LDFLAGS="-s -Wl,--stack=0x800000" bootstrap2


And I get the following error.


../../../gcc-4.5-20091022/libgcc/../gcc/libgcc2.c:1813: warning:
implicit declaration of function '__builtin_huge_valq'
../../../gcc-4.5-20091022/libgcc/../gcc/libgcc2.c:1813: error: size of
array 'compile_type_assert' is negative
make[3]: *** [_multc3.o] Error 1
make[3]: Leaving directory `/home/Jim/gcc-4.5/mingw32/libgcc'


I go back to my original question.  Has someone built 4.5 on mingw and
if so what was your config and build options?

Cheers

Jim

Hi,

there is nothing wrong with your configure option, GCC 4.5 should build
fine. If possible, please post the full error message including the
command invoked that caused the error and some information about your
GCC installation (mingwrt, w32api, gcc versions).

I've built GCC to target mingw not long ago, maybe this is a new
problem. You could retry with SVN head version.

__builtin_huge_valq was already added in 2008 for i386. See
<http://www.nabble.com/PATCH,-i386:-add-__builtin_huge_valq-td20948755.html>.

I will try an earlier version of 4.5 as I just took the head
