Compiling GCC for MinGW & Cross-Compiling with Linux

I've made this little guide to get a working MinGW gcc-4.0.3 up to gcc-4.1.2 (should work with binutils too)

i did have the latest build on my googlepage but it ran out of bandwidth, unless anybody canrecommend a freehost - its back to the previous way

try this (check http://www.mingw.org/download.shtml for updates)

MinGW-5.1.3-[candidate only base-files]

http://prdownloads.sf.net/mingw/MinG...3.exe?download

MSYS-1.0.10.exe

http://prdownloads.sf.net/mingw/MSYS...0.exe?download

if you need cvs
http://prdownloads.sf.net/mingw/msys...1.exe?download

and when installing if the connection drops, click retry (sf problem)

and i recommend to get latest runtime,w32api headers
http://sourceforge.net/project/showf...ease_id=158844
http://sourceforge.net/project/showf...ease_id=158847

and the new binutils that allows spaces in filenames
https://sourceforge.net/forum/forum.php?forum_id=661143

and if building hogs your system i recommend editing the msys.bat

change the:
line 62: start rxvt ... into start /LOW rxvt ... and
line 66: start sh ... into start /LOW sh ...
(more reliable for your system, you can do other while building)

get gcc-sources try here:
http://www.mirrorservice.org/sites/s...t.com/pub/gcc/

release directory or whatever


***** most of the pre-released/snapshots of gcc needs bison,flex and sometimes libiconv, libtool

bison into \mingw\ directory --
http://gnuwin32.sourceforge.net/down...on-bin-zip.php
http://gnuwin32.sourceforge.net/down...on-dep-zip.php

flex into \mingw\ directory --
http://gnuwin32.sourceforge.net/down...ex-bin-zip.php

libtool into \mingw\ directory --
http://gnuwin32.sourceforge.net/down...ol-bin-zip.php

libiconv into \mingw\
http://gnuwin32.sourceforge.net/down...nv-bin-zip.php
http://gnuwin32.sourceforge.net/down...nv-dep-zip.php

and maybe newer gnu-make (not needed but useful and sometimes buggy)
http://prdownloads.sourceforge.net/m...3.exe?download

installing the newer make delete/rename old msys\1.0\bin\make.exe and install the new make into \mingw\ and then
rename the new mingw32-make.exe into make.exe

make --version to check

or compile your own from http://ftp.gnu.org/gnu/make/

***

The directory that should contain system headers does not exist:
/usr/include

create an empty include folder in \msys\1.0\

***

make[2]: Leaving directory `/home/user/svn/gcc-4_1-branch/build/libcpp'
make[2]: Entering directory `/home/user/svn/gcc-4_1-branch/build/gcc'
Makefile:1280: *** target pattern contains no `%'. Stop.
make[2]: Leaving directory `/home/user/svn/gcc-4_1-branch/build/gcc'
make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory `/home/user/svn/gcc-4_1-branch/build'
make: *** [all] Error 2

check makefile = LD = ld
(not LD = ?:/mingw/bin/../lib/gcc/mingw32/???/../../../../mingw32/bin/ld.exe)
i think related to --with-gcc --with-gnu-ld --with-gnu-as

or delete ld.exe from \mingw\mingw32\bin or empty the folder that's what i did
(but i think the newer binutils fixes that anyway, will check later)

****

Step 1

cd yourgcc-src
mkdir build
cd build

Step 2
tip. before you install new gcc zip your \mingw\ directory ... you never know

Pass 1

append "&> output-results.txt" without quotes to echo to file (displayed text into a file)

after some experiments, i found symbolic links are broke, not sure on how to fix it

you can append: --with-dwarf2 -s (for silent output) to configure line
you can append &>result.txt to pipe any shell output to file


*** for gcc 4.1+ use bison,flex see notes on ld.exe

*** for gcc 4.2+ append --disable-werror

*** updated configure 2006.12.23 (remove --host=mingw32 --target=mingw32 to build for your system)

(remove '"CFLAGS=-O2" "LDFLAGS=-s" --enable-optimize' if debugging the compiler)


for i386
Quote:
../configure --enable-languages=c -v --enable-optimize --host=mingw32 --build=mingw32 --target=mingw32 --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x
for i686
Quote:
../configure --enable-languages=c -v --enable-optimize --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x

Quote:
make "CFLAGS=-O2" "LDFLAGS=-s"
or
Quote:
make bootstrap "CFLAGS=-O2" "LDFLAGS=-s"
* if the bootstrap fails something is wrong with gcc compiler itself, means it can't rebuild itself with itself


(you can save it for later, if you re-install mingw just copy the folder back in)
Quote:
make DESTDIR=/home/gcc-build install
(the normal install)
Quote:
make install
Quote:
make html
(if you want the html - docs, there should be here yourgcc-src\libstdc++-v3\docs\html )

close and re-load ming

Step 3

Pass 2

empty your build directory

if you need g77 its not supported in gcc 4+, try gcc 3.4.4
but if want to build gfortran read further down

available languages are: c,c++,f95,java,objc,obj-c++,treelang

*** for gcc 4.2+ append --disable-werror


for i386
Quote:
../configure --enable-languages=c,c++ -v --enable-optimize --host=mingw32 --build=mingw32 --target=mingw32 --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x
for i686
Quote:
../configure --enable-languages=c,c++ -v --enable-optimize --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x

Quote:
make "CFLAGS=-O2" "LDFLAGS=-s"
or
Quote:
make bootstrap "CFLAGS=-O2" "LDFLAGS=-s"
* if the bootstrap fails something is wrong with gcc compiler itself, means it can't rebuild itself with itself


(you can save it for later, if you re-install mingw just copy the folder back in)
Quote:
make DESTDIR=/home/gcc-build install
(the normal install)
Quote:
make install
close and re-load ming

Step 4

Pass 3 ( build gcc with gcc with profiled bootstrap to get a faster compiler)
this not necessary but you get a faster compiler

empty your build directory


for i386
Quote:
../configure --enable-languages=c,c++ -v --enable-optimize --host=mingw32 --build=mingw32 --target=mingw32 --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x
for i686
Quote:
../configure --enable-languages=c,c++ -v --enable-optimize --prefix=/mingw --oldincludedir=/mingw/include --enable-threads --disable-nls --disable-win32-registry --disable-shared --without-x

make "CFLAGS=-O2" "LDFLAGS=-s"
or
Quote:
make bootstrap "CFLAGS=-O2" "LDFLAGS=-s"
* if the bootstrap fails something is wrong with gcc compiler itself, means it can't rebuild itself with itself


(you can save it for later, if you re-install mingw just copy the folder back in)
Quote:

(the normal install)

***

Fortran, GMP, MPFR

Building GMP

download gmp from

Maybe adding Fortran (g77)? I'm 95% certain that'll compile with no problems. GCC/MinGW usually stumbles with ObjectiveC and/or Java.

Why do people insist on having GCC 4 working with MinGW? What was wrong with GCC 3.4.5? I've been using that with no problems at all.

can do, i myself - not used fortran for ages

people must like new toys to play with - optimizing stuff gcc 4.1 sounds interesting

@cc979, thanks for the guide.

And I've a suggestion here. I see the commands to MinGW are mixed with your comments. It will be much clearer if you put the commands in code box like this:
Code:
../configure --enable-languages=c --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --disable-win32-registry --disable-shared --enable-sjlj-exceptions --without-x --enable-hash-synchronization --enable-libstdcxx-debug
Or using "quote":
Quote:

A working gcc compilation guide should have about 30 detailed steps, not 4 or 5.
after installing MSYS you get a /sys/1.0/ directory or where you have installed

in '30 steps' have tried ?

path typo ? tell me where

I mean about 30 steps like this otherwise it's not a step by step guide, but a quick reference (kind of reminder) for people who already know how to compile it. I'll try to fix the gcc guide (for gcc-core-4.2.x) and post it later here.
cheers

Yes! This is awesome, mainly because I've been itching to use OpenMP in ffmpeg and gcc 4.3 finally implements it. I'll probably have to run some experiments with it first to see how functional it is.

your welcome, let me know how it goes for you - i had problems with the baseclasses compiling ffdshow myself, help - if you can do it

cheers

with gcc-4.3 ffdshow fails on baseclasses

see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20652

and some else ran into compiling other sources

I was only going to use it for lavc/mplayer, so that shouldn't affect me to much at the moment. It'll be interesting trying to test for any bugs introduced though.

btw, was this cross-compiled from linux, or compiled off the existing 4.0/4.1 gcc for win32?

i used win32 mingw gcc 4.0.3 if remember as it was after few failed attempts, till i realised what it needed

Somehow all the executables in your builds are much larger than 'official' mingw32 builds. I once made a build myself and had the same problem.

Perhaps the executables contain debugging or other unneeded code? Hopefully you can figure out what is wrong and 'fix' it. As it might affect the performance of the compilers too.

i had it include GMP, MPFR libs maybe thats affecting it, i look into it

The 2.17.50-200700129-1 snapshot incorporates modifications to official
binutils CVS since last update. In addition it patches windres to allow
use of spaces in filenames,
