1How to build gcc-4.5 natively on Haiku:
2
3checkout the buildtools from the haiku repository
4cd into the buildtools folder (where this file lives)
5
6declare the current gcc-version-date like this:
7	export GCCDATE=110631
8	export GCCVERSION=gcc-4.5.3-haiku-${GCCDATE}
9(just use the current date instead of '110631' and the current gcc version
10instead of '4.5.3')
11
12compile binutils:
13
14	mkdir binutils-obj
15	cd binutils-obj
16	LC_ALL=POSIX CFLAGS="-O2" CXXFLAGS="-O2" ../binutils/configure \
17		--prefix=/boot/develop/abi/x86/gcc4/tools/${GCCVERSION} \
18		--disable-nls --enable-shared=yes \
19		--with-htmldir=html-docs
20	LC_ALL=POSIX make -j2
21	cd ..
22
23compile gcc:	
24
25	mkdir gcc-obj
26	cd gcc-obj
27	LC_ALL=POSIX CFLAGS="-O2" CXXFLAGS="-O2" ../gcc/configure \
28		--prefix=/boot/develop/abi/x86/gcc4/tools/${GCCVERSION} \
29		--enable-shared --enable-languages=c,c++ \
30		--disable-nls --without-libiconv-prefix --disable-libstdcxx-pch \
31		--with-htmldir=html-docs
32	LC_ALL=POSIX make -j2 bootstrap
33	cd ..
34
35Ok, now everything is compiled and ready, waiting to be installed:
36
37	mkdir /boot/develop/abi/x86/gcc4/tools/${GCCVERSION}
38	cd binutils-obj
39	make install install-html
40	cd ../gcc-obj
41	make install install-html
42	ln -sfn ${GCCVERSION} /boot/develop/abi/x86/gcc4/tools/current
