[omniORB] omniORB 4.2.3 - mingw x86 - tcpSocket.cc error - sprintf

[DIETMAR MAY]

When building omniORB 4.2.3 with cygwin's mingw compiler, I receive the error below.

Looks like either it's building with wchar support, or one of the #defines is missing and I'm picking up the wrong #if code sections.

omkdepend builds fine, as do a number of other components up to tcpSocket.cc

Any ideas?

I've installed Cygwin x86, with mingw64-i686-gcc-g++ and cygwin binutils
packages.

I've downloaded and installed MSVC++ 2008 SP1 redistributables

https://www.microsoft.com/en-US/download/details.aspx?id=5582

and copied MSVCRT90.DLL to cygwin's /usr/bin directory.

I've edited <top>/config/config.mk and enabled

platform = x86_win32_mingw

I've installed python.org's python interpreter, and don't have cygwin's
python installed:

$printenv PATH

/usr/local/bin:/usr/bin: ... :/C/programs/python

$ which python
/C/programs/python/python

I've edited <top>/mk/platforms/x86_win32_mingw.mk and updated the PYTHON
macro:

PYTHON = /c/programs/python/python

(cygwin's /etc/fstab contains "c:/  /C     ntfs binary,posix=0,user 0 0")

I've changed <top>/mk/mingw.mk:

MINGW = /usr/bin/i686-w64-mingw32-
AR = ar cq
CXX = $(MINGW)g++
CXXLINK = $(MINGW)g++
CC = $(MINGW)gcc
CLINK = $(MINGW)gcc
