Compiling GCC for MinGW & Cross-Compiling with Linux

[cc979]

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\

***

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

../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

../configure --enable-languages=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

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)

make DESTDIR=/home/gcc-build install

(the normal install)

make install

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

../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

../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

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)

make DESTDIR=/home/gcc-build install

(the normal install)

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

../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

../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

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)

make DESTDIR=/home/gcc-build install

(the normal install)

make install
