Installation Notes for Windows XP/MinGW
|
| 2 |
=======================================
|
| 3 |
|
| 4 |
It is possible to compile CDuce under cygwin with the MinGW toolchain.
|
| 5 |
Currently, the resulting executable still depends on the cygwin1.dll.
|
| 6 |
The suspect is pcre, but the source of the "pollution" has not been
|
| 7 |
determined.
|
| 8 |
|
| 9 |
The dependencies can be checked with the "cygcheck" command under
|
| 10 |
cygwin. Note that cygcheck searches in the PATH, i.e., if a binary is
|
| 11 |
not in the path, one must give the full path. To check a binary in
|
| 12 |
the mingw directory (e.g., C:\ocamlmgw\bin\cduce), one must give the
|
| 13 |
Mingw path (C:/ocamlmgw/bin/cduce) to cygcheck, not the cygwin path
|
| 14 |
(/cygdrive/c/ocamlmgw/bin).
|
| 15 |
|
| 16 |
|
| 17 |
When compiling under the MinGW toolchain, the option -mno-cygwin must
|
| 18 |
always be passed to the C compiler and linker. It is also necessary
|
| 19 |
to ensure that one is not linking against any cygwin libraries at any
|
| 20 |
point. The MinGW libraries are located in /usr/lib/...
|
| 21 |
|
| 22 |
|
| 23 |
Steps:
|
| 24 |
|
| 25 |
----------------------------------------------------------------------
|
| 26 |
1) In Cygwin, add the packages for MinGW support to the ones already
|
| 27 |
mentioned in INSTALL.WIN32.
|
| 28 |
|
| 29 |
gcc-mingw-core
|
| 30 |
mingw-runtime
|
| 31 |
w32-api
|
| 32 |
<maybe more, which may be the cause of our problem?>
|
| 33 |
|
| 34 |
Remove the prce packages from Cygwin, to make sure that the pcre
|
| 35 |
used is the one installed under Mingw.
|
| 36 |
|
| 37 |
|
| 38 |
----------------------------------------------------------------------
|
| 39 |
2) Install tcl/tk in Windows
|
| 40 |
|
| 41 |
Install Tcl/Tk in a windows top directory, eg, C:\Tcl
|
| 42 |
|
| 43 |
binaries available as described in ocaml notes (README.win32).
|
| 44 |
|
| 45 |
|
| 46 |
----------------------------------------------------------------------
|
| 47 |
3) OCAML
|
| 48 |
|
| 49 |
Build ocaml 3.10 for the mingw toolchain as specified in README.win32,
|
| 50 |
but with the following addition from the ocaml mailing list:

Hi,
|
| 58 |
|
| 59 |
I succeeded in the past to build ocaml and lablgtk with MinGW/MSYS
|
| 60 |
(without Cygwin), together with ocamlmklib.
|
| 61 |
In the ocaml tree, change the following files:
|
| 62 |
|
| 63 |
1) ocamlmklib
|
| 64 |
|
| 65 |
The 'trick' is to copy the Makefile part of ocamlmklib in the Makefile.nt
|
| 66 |
|
| 67 |
edit tools/Makefile.nt and change the Line 26
|
| 68 |
all: ocamldep ocamlprof ocamlcp.exe ocamlmktop.exe primreq
|
| 69 |
in
|
| 70 |
all: ocamldep ocamlprof ocamlcp.exe ocamlmktop.exe primreq
|
| 71 |
ocamlmklib.exe
|
| 72 |
|
| 73 |
append the following lines after the ocamlmktop part:
|
| 74 |
|
| 75 |
# To help building mixed-mode libraries (Caml + C)
|
| 76 |
|
| 77 |
ocamlmklib.exe: myocamlbuild_config.cmo ocamlmklib.cmo
|
| 78 |
$(CAMLC) $(LINKFLAGS) -o ocamlmklib.exe myocamlbuild_config.cmo
|
| 79 |
ocamlmklib.cmo
|
| 80 |
|
| 81 |
ocamlmklib.cmo: myocamlbuild_config.cmi
|
| 82 |
myocamlbuild_config.ml: ../config/Makefile
|
| 83 |
../build/mkmyocamlbuild_config.sh
|
| 84 |
cp ../myocamlbuild_config.ml .
|
| 85 |
|
| 86 |
install::
|
| 87 |
cp ocamlmklib.exe $(BINDIR)/ocamlmklib.exe
|
| 88 |
|
| 89 |
clean::
|
| 90 |
rm -f ocamlmklib.exe
|
| 91 |
|
| 92 |
ocamlmklib.ml: ocamlmklib.mlp ../config/Makefile
|
| 93 |
echo '(* THIS FILE IS GENERATED FROM ocamlmklib.mlp *)' >ocamlmklib.ml
|
| 94 |
sed -e "s|%%BINDIR%%|$(BINDIR)|" \
|
| 95 |
-e
|
| 96 |
"s|%%SUPPORTS_SHARED_LIBRARIES%%|$(SUPPORTS_SHARED_LIBRARIES)|" \
|
| 97 |
-e "s|%%MKSHAREDLIB%%|$(MKSHAREDLIB)|" \
|
| 98 |
-e "s|%%BYTECCRPATH%%|$(BYTECCRPATH)|" \
|
| 99 |
-e "s|%%NATIVECCRPATH%%|$(NATIVECCRPATH)|" \
|
| 100 |
-e "s|%%MKSHAREDLIBRPATH%%|$(MKSHAREDLIBRPATH)|" \
|
| 101 |
-e "s|%%RANLIB%%|$(RANLIB)|" \
|
| 102 |
ocamlmklib.mlp >> ocamlmklib.ml
|
| 103 |
|
| 104 |
beforedepend:: ocamlmklib.ml
|
| 105 |
|
| 106 |
clean::
|
| 107 |
rm -f ocamlmklib.ml
|
| 108 |
|
| 109 |
It seems that this is not in the ocaml distribution because it doesn't
|
| 110 |
work under MSVS, only under MinGW, and since there is only one
|
| 111 |
Makefile.nt...
|
| 112 |
|
| 113 |
|
| 114 |
adjust PATH:
|
| 115 |
|
| 116 |
PATH=$PATH:/cygdrive/c/ocamlmgw/bin
|
| 117 |
|
| 118 |
|
| 119 |
----------------------------------------------------------------------
|
| 120 |
4) findlib
|
| 121 |
|
| 122 |
Patch configure replacing
|
| 123 |
stdlib = `get_stdlib`
|
| 124 |
with
|
| 125 |
stdlib = /cygdrive/c/ocamlmgw/lib
|
| 126 |
|
| 127 |
./configure -bindir /cygdrive/c/ocamlmgw/bin
|
| 128 |
|
| 129 |
Patch Makefile.config replacing
|
| 130 |
OCAML_CORE_MAN = /usr/local/man
|
| 131 |
with
|
| 132 |
OCAML_CORE_MAN = /cygdrive/c/ocamlmgw/man
|
| 133 |
(since ocaml for mingw does not install the man directories, the
|
| 134 |
mandir option does not work).
|
| 135 |
|
| 136 |
make all
|
| 137 |
make opt
|
| 138 |
make install
|
| 139 |
|
| 140 |
|
| 141 |
----------------------------------------------------------------------
|
| 142 |
5) ulex
|
| 143 |
|
| 144 |
This gets stuck with the error "can't found ocamlbuildlib.cma in
|
| 145 |
ocamlbuild -where", which is not surprising, since ocamlbuild -where
|
| 146 |
returns /ocamlbuildlib/lib, which doesn't exist. See ocaml bug 4379.
|
| 147 |
This is supposedly fixed in ocaml 3.10.1, but it still doesn't seem to
|
| 148 |
work.
|
| 149 |
|
| 150 |
Until this bug is fixed, patch Makefile to use
|
| 151 |
|
| 152 |
ocamlbuild -install-lib-dir "C:\ocamlmgw\lib\ocamlbuild"
|
| 153 |
|
| 154 |
(or whereever your mingw installation is). This workaround is
|
| 155 |
suitable for cygwin, but it may not work in Mingw/MSYS.
|
| 156 |
|
| 157 |
Remember to also add -classic-display to ocamlbuild, since we are
|
| 158 |
building with ocaml 3.10.
|
| 159 |
|
| 160 |
make all
|
| 161 |
make all.opt
|
| 162 |
make install
|
| 163 |
|
| 164 |
|
| 165 |
----------------------------------------------------------------------
|
| 166 |
6) PCRE:
|
| 167 |
|
| 168 |
Since the pcre that comes with cygwin cannot be used in mingw, install
|
| 169 |
pcre before pcre-ocaml. This is simpler if pcre is not installed in
|
| 170 |
cygwin.
|
| 171 |
|
| 172 |
Go back to cygwin's setup.exe and install gcc-g++ (C++ compiler).
|
| 173 |
|
| 174 |
Download pcre-7.2 from www.pcre.org or
|
| 175 |
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre
|
| 176 |
|
| 177 |
To configure pcre-7.2:
|
| 178 |
|
| 179 |
If pcre is installed in cygwin, patch ltmain.sh so that need_relink is
|
| 180 |
always "no", that may avoid the cygwin dependency.
|
| 181 |
|
| 182 |
./configure --prefix="C:/ocamlmgw" --exec-prefix="C:/ocamlmgw" --includedir=/usr/include/mingw --disable-cpp --enable-utf8 CFLAGS="-mno-cygwin -I /usr/include/w32api -I /usr/include/mingw"
|
| 183 |
|
| 184 |
Patch the Makefile to replace cygwin with mingw everywhere it occurs
|
| 185 |
(except in -mno-cygwin).
|
| 186 |
|
| 187 |
Patch the libtool file similarly.
|
| 188 |
|
| 189 |
make
|
| 190 |
|
| 191 |
make install
|
| 192 |
|
| 193 |
This installs the libs in the ocaml mingw directory
|
| 194 |
(e.g. C:\ocamlmgw\lib, but the .h files in /usr/include/mingw. This
|
| 195 |
should be suitable for continued compilation using the mingw
|
| 196 |
toolchain, but not for a pure mingw compilation.
|
| 197 |
|
| 198 |
Check with cygcheck whether, eg, pcregrep.exe, depends on the
|
| 199 |
cygwin1.dll and cygpcre-0.dll.
|
| 200 |
----------------------------------------------------------------------
|
| 201 |
7) pcre-ocaml:
|
| 202 |
|
| 203 |
Edit Makefile.conf to contain
|
| 204 |
|
| 205 |
export STATIC = yes
|
| 206 |
export INCDIRS := /usr/include/mingw
|
| 207 |
export LIBDIRS := C:/ocamlmgw/lib
|
| 208 |
MINGW=1
|
| 209 |
CC=gcc
|
| 210 |
export GCC
|
| 211 |
export MINGW
|
| 212 |
|
| 213 |
(If cc is not set, it defaults to cc, which causes 'make' to fail
|
| 214 |
spectacularly during
|
| 215 |
|
| 216 |
ocamlc -c -cc "cc" -ccopt "-fPIC -O2 -DPIC -mno-cygwin -I /usr/include/mingw -o pcre_stubs.o" pcre_stubs.c
|
| 217 |
|
| 218 |
sometimes even to the point of crashing cygwin.)
|
| 219 |
|
| 220 |
make
|
| 221 |
make install
|
| 222 |
|
| 223 |
The file pcre_make.win32/Makefile.mingw does not seem to work, either
|
| 224 |
it is for Mingw/MSYS or it has not been updated.
|
| 225 |
|
| 226 |
The file README.win32 concerns MS Visual Studio, i.e., it is
|
| 227 |
irrelevant.
|
| 228 |
|
| 229 |
To check that pcre actually works in ocaml:
|
| 230 |
|
| 231 |
make a file foo.ml that uses Pcre, eg
|
| 232 |
|
| 233 |
open Prce;;
|
| 234 |
qreplace;;
|
| 235 |
|
| 236 |
compile it with
|
| 237 |
|
| 238 |
ocamlc -I "C:/ocamlmgw/lib/site-lib/pcre" foo.ml
|
| 239 |
|
| 240 |
----------------------------------------------------------------------
|
| 241 |
8) pxp
|
| 242 |
|
| 243 |
./configure -without-wlex -without-wlex-compat -lexlist utf8,iso88591 -without-pp
|
| 244 |
|
| 245 |
make all
|
| 246 |
make opt
|
| 247 |
make install
|
| 248 |
|
| 249 |
|
| 250 |
----------------------------------------------------------------------
|
| 251 |
9) CDuce
|
| 252 |
|
| 253 |
./configure --prefix="C:/ocamlmgw" --mliface="C:/cygwin/usr/src/ocaml-3.10.0/"
|
| 254 |
|
| 255 |
patch Makefile.conf to set FORPACK=true
|
| 256 |
(For some reason that fails in configure.ml)
|
| 257 |
|
| 258 |
Patch Makefile.distrib to set
|
| 259 |
|
| 260 |
LINK = $(CAMLOPT) -custom -linkpkg
|
| 261 |
|
| 262 |
in line 71 to statically link the library.
|
| 263 |

|
| 266 |
make install
