[omniORB] Compiling under Windows with MinGW

[Matias Guijarro]

Hello,

I am trying to compile omniORB 4.1.0 under Windows in a
MinGW environment, without any success for the moment.

I changed the platform in config/config.mk to "x86_win32_mingw",
then I started the configure script and it runs fine :

checking build system type... i686-pc-mingw32
checking host system type... i686-pc-mingw32
checking for gcc... gcc
[...]

But anyway when doing "make" I get the following error :

making export in src/tool/omkdepend...
make[3]: Entering directory
`/home/GUIJARRO/omniORB-4.1.0/src/tool/omkdepend'

I wonder if __OSVERSION__=0 is normal ?

This is the same problem as in this post :

I tried what has been answered :
http://www.omniorb-support.com/pipermail/omniorb-list/2006-July/027818.html

So now I don't build omkdepend, but I still get errors :

make[3]: *** [static/posix.o] Error 1
make[3]: Leaving directory `/home/GUIJARRO/omniORB-4.1.0/src/lib/omnithread'

For me it seems the platform I specified in config/config.mk is ignored ?

Can somebody gives some hint ?

Please help!!!

Thanks in advance.

If you're using the configure script, you don't need to edit config.mk.
It doesn't hurt if you do, though.

The autoconf configuration doesn't have any entries for MinGW, so it
falls back to some guesses. If you look in configure.ac and
mk/beforeauto.mk.in, you'll see a whole load of things about specific
platforms. If you copy the ones for Cygwin, that will probably be a good
starting point.

I only noticed after I sent the email to the list that everything
to compile with MinGW is already available, but it works
without the configure script.

One has to change config/config.mk to select the right
platform (x86_win32_mingw) and edit mk/platforms/x86_win32_mingw.mk
to reflect Python's installation, then it is possible to make
everything going to the src directory and doing "make export".

Maybe it would be good to add the explanations above to
a README file ?

By the way : I discovered something wrong when building
with MinGW, I had to change EXTRA_LIBS in src/lib/omniORB/connections/dir.mk
to be -ladvapi32 instead of advapi32.lib.

And also at the end it tries to execute "rebase.exe" on the
compiled DLLs, this is not necessary with MinGW ; I had to
edit the makefile manually to prevent this step.

Cheers,
Matias.
