1How to build gcc-2.95.3 for Haiku:
2
3cd into the buildtools/legacy folder
4
5declare the current gcc-version-date like this:
6	export GCCDATE=100818
7(just use the current date instead of '100818', ie. 'yymmdd')
8If your GCC version includes new features, make sure you also alter the
9version in gcc/gcc/version.c.
10
11compile binutils:
12
13	mkdir binutils-obj
14	cd binutils-obj
15	LC_ALL=POSIX CFLAGS="-O2" CXXFLAGS="-O2" ../binutils/configure \
16		--prefix=/boot/common/develop/tools/gcc-2.95.3-${GCCDATE} \
17		--disable-nls --enable-shared=yes
18	LC_ALL=POSIX make
19	cd ..
20
21
22compile gcc:
23
24	mkdir gcc-obj
25	cd gcc-obj
26	LC_ALL=POSIX CFLAGS="-O2" CXXFLAGS="-O2" ../gcc/configure \
27		--prefix=/boot/common/develop/tools/gcc-2.95.3-${GCCDATE} \
28		--disable-nls --enable-shared=yes --enable-languages=c,c++
29	LC_ALL=POSIX make bootstrap
30	# the above will fail when compiling builtinbuf.cc, but we can ignore that
31	# since it's trying to build libstdc++.so, which haiku provides anyway
32	cd ..
33
34Ok, now everything is compiled and ready, waiting to be packaged:
35
36	mkdir /boot/develop/abi/x86/gcc2/tools/gcc-2.95.3-haiku-${GCCDATE}
37	cd binutils-obj
38	make install
39	cd ..
40	cd gcc-obj
41	make install
42	cd ..
43	ln -sfn gcc-2.95.3-haiku-${GCCDATE} /boot/develop/abi/x86/gcc2/tools/current
44
45To build the binutils HTML documentation (needed by the GCC2 package build
46script):
47
48	cd binutils-obj
49	make install-html
50	cd ..
