Fixes for building erlang under windows

[Davide Marquês]

Hi all,

Here are some fixes I picked up along the way while building erlang on a
fresh install of Windows.

Fix for cygwin environments that might have non-default cygdrive prefixes:

> $ERL_TOP/erts/configure.in:
> 3242:
>     open_ssl_default_dir=`cygpath "c:\OpenSSL"`
>     for dir in $extra_dir $open_ssl_default_dir \
> 3493:
>     kerberos_default_dir=`cygpath "c:\kerberos"`
>     SSL_KRB5_INCLUDE=
>     if test "x$ssl_krb5_enabled" = "xyes" ; then
>         AC_MSG_CHECKING(for krb5.h in standard locations)
>     for dir in $extra_dir $SSL_ROOT/include $SSL_ROOT/include/openssl \
>         $SSL_ROOT/include/kerberos $kerberos_default_dir/include \
>

> 21867:

> 22235:
>     kerberos_default_dir=`cygpath "c:\kerberos"`
>     SSL_KRB5_INCLUDE=

>     echo $ECHO_N "checking for krb5.h in standard locations... $ECHO_C" >&6
>         for dir in $extra_dir $SSL_ROOT/include $SSL_ROOT/include/openssl \
>             $SSL_ROOT/include/kerberos $kerberos_default_dir/include \
>

Needed changes for OpenSSL installations in non-default paths:

> Using the "--with-ssl" option in configure (EVEN IF OpenSSL is installed
> in a default location) will set the SSL_LIBDIR variable to an incorrect
> value
> and crypto and ssh compilation will fail.
>
>     - If OpenSSL is found in the default location:
>         $ ./otp_build configure
>         ...
>         $ grep "SSL_LIBDIR =" lib/crypto/c_src/win32/Makefile
>         SSL_LIBDIR = /c/OpenSSL/lib
>
>     - Otherwise if we provide the path to OpenSSL:
>         $ ./otp_build configure --with-ssl="/c/OpenSSL"
>         ...
>         $ grep "SSL_LIBDIR =" lib/crypto/c_src/win32/Makefile
>         SSL_LIBDIR = /c/OpenSSL/lib/VC
>
> $ERL_TOP/erts/configure:22139
> $ERL_TOP/erts/configure.in:3418
>     if test "x$MIXED_CYGWIN" = "xyes" -a -d "$with_ssl/lib/VC"; then
>         SSL_LIBDIR="$with_ssl/lib/VC"
> should include the additional tests:

>             SSL_LIBDIR="$dir/lib/VC"
>         elif test -f "$dir/lib/ssleay32.lib" -o \

That's it for now.

I'm rewriting a step-by-step
tutorial<http://github.com/davide/erl_interface-examples/tree/master/doc/>on
how to build erlang under windows
using Visual C++ Express 2008 which I'll share when complete (wxWidgets
and gs are still giving me an hard time).

Cheers,
:Davide

Hi again!

The gs application build fails under windows due to a missing
binaries/win32.tar.gz.
The configure step does check to see whether the file exists but the
Makefile ignores
that test result and overrides/corrects the TCL_TAR value even if the file
is missing.

The fix:
$ERL_TOP/lib/gs/tcl/Makefile.in:36

Replace:
ifeq ($(TARGET),win32)
TCL_TAR = binaries/win32.tar.gz
else
TCL_TAR = @TCL_TAR@
endif

by:
TCL_TAR = @TCL_TAR@
ifneq ($(TCL_TAR),)
ifeq ($(TARGET),win32)
TCL_TAR = binaries/win32.tar.gz
endif
endif

One down, one (wxWidgets) to go.

Cheers,
:Davide

What's wrong with wxWidgets?

Hi Mazen,
Simply going through the steps in README.win32 doesn't seem to be enough for
configure to pick up the wxWidgets installation/libraries.

These were the steps I took:
- run the wxWidgets-2.8.10 installer;
- edit <wxWidgets dir>/include/wx/msw/setup.h and enable:
- wxUSE_GLCANVAS
- wxUSE_POSTSCRIPT
- wxUSE_GRAPHICS_CONTEXT
- open <wxWidgets dir>/build/msw/wx.dsw (letting VC convert the projects)
- build the "Unicode Release" and "Unicode Debug" configurations
- open <wxWidgets dir>/contrib/build/stc/stc.dsw (letting VC convert the
projects)
- build the "Unicode Release" and "Unicode Debug" configurations
After which the C:\Program Files\wxWidgets-2.8.10\lib\vc_lib folder contais
195MB of .lib goodness (wxbase28d.lib, wxbase28u.lib, wxbase28d_net.lib,
wxbase28u_net.lib, ...).

This is the relevant part of the configure output:

> checking for debug build of WxWidgets... checking for wx-config... no

checking for standard build of WxWidgets... checking for wx-config...
> (cached) no

The wx-config didn't exist at this point. As there was a wx-config.in file I
ran configure to create it. But that didn't help much.

Here are some of its outputs:

VC2008: wxWidgets-2.8.10 $ ./wx-config --libs-L/c/Progra~1/wxWidgets-2.8.10/lib
  -lwx_msw_richtext-2.8 -lwx_msw_aui-2.8 -lwx_msw_xrc-2.8 -lwx_msw_qa-2.8
-lwx_msw_html-2.8 -lwx_msw_adv-2.8 -lwx_msw_core-2.8 -lwx_base_xml-2.8
-lwx_base_net-2.8 -lwx_base-2.8

VC2008: wxWidgets-2.8.10 $ ./wx-config --static --libs

  Warning: No config found to match: ./wx-config --static --libs
           in /c/Progra~1/wxWidgets-2.8.10/lib/wx/config
  If you require this configuration, please install the desired
  library build.  If this is part of an automated configuration
  test and no other errors occur, you may safely ignore it.
  You may use wx-config --list to see all configs available in
  the default prefix.


VC2008: wx $ wx-config --unicode --debug=yes  Warning: No config found to
match: /c/Progra~1/wxWidgets-2.8.10/wx-config --unicode --debug=yes
           in /c/Progra~1/wxWidgets-2.8.10/lib/wx/config

  library build.  If this is part of an automated configuration
  test and no other errors occur, you may safely ignore it.
  You may use wx-config --list to see all configs available in

The configure fails after this last check:

                is in LD_LIBRARY_PATH or equivalent variable and
                wxWidgets version is 2.8.0 or above.


I'm obviously clueless. Any tips? :)

 From the README.win32
=>  Get and unpack wxWidgets-2.8.9 or higher to /opt/local/pgm inside cygwin
                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The configure script only looks there on windows when building with VC++
We didn't try anything fancy for the windows build there are so few building
from the source on that platform.

Doh!
Copying the files now. I'll let you know how it goes.

Hope my tutorial/guide can help improve that. At least it shows that it's
possible to build erlang with a free (as in beer) toolchain.

Thanks for the RTFM. :)

Hi again,

With a bit of help (thanks guys!) I was able to build everything and now
have a (hopefully) fully working erlang installation.
All the patches and build steps are available here:
Building erlang using Visual C++ 2008 Express
Edition<http://github.com/davide/erl_interface-examples/blob/master/doc/Building%20erlang%20using%20Visual%20C++%202008%20Express%20Edition.txt>

I'll be doing development on this new system and I'll let you know if
anything's broken.

Cheers,
:Davide
