Kun,
The PATH environment variables is used only to find executables and the DLL
(dynamically linked libraries) those executables require.
Include files required during C or C++ compilation are located via a
separate search path maintained by the compiler and not driven by any
environment variable, at least not in the Cygwin compiler, which is GCC.
You'll probably need to learn about the conventions and rules of C
programming and compilers (and related tools such as "make") in order to be
able to generalize the build scripts you're using.
By the way, is this the same CLDC whose home page is
<http://java.sun.com/products/cldc/>? If so, are you also building the KVM
yourself? If not, is the KVM also built with GCC? If these two components
are not going to be built with the same compilers, then you must verify
that the compilers' ABIs (application binary interfaces) are compatible, or
the CLDC native library you're building will not be usable from the KVM.
It is a certainty that a Java Native Interface library built using GCC will
not be able to be accessed from the Sun JVM for Windows.
Also, just to be pedantic, it's "Cygwin," not "CygWin."

Kun,
I need to correct myself (since no one else did!)...

There _are_ environment variables to tell GCC where to find files. This is
an excerpt from the (rather long) man page for "gcc":
-==--==--==--==--==--==--==--==--==--==--==--==--==--==--==-
Some additional environments variables affect the behavior
of the preprocessor.
CPATH
C_INCLUDE_PATH
CPLUS_INCLUDE_PATH
OBJC_INCLUDE_PATH
Each variable's value is a list of directories
separated by a special character, much like PATH, in
which to look for header files. The special
character, PATH_SEPARATOR, is target-dependent and
determined at GCC build time. For Windows-based
targets it is a semicolon, and for almost all other
targets it is a colon.
CPATH specifies a list of directories to be searched
as if specified with -I, but after any paths given
with -I options on the command line. The environment
variable is used regardless of which language is being
preprocessed.
The remaining environment variables apply only when
preprocessing the particular language indicated. Each
specifies a list of directories to be searched as if
specified with -isystem, but after any paths given
with -isystem options on the command line.
-==--==--==--==--==--==--==--==--==--==--==--==--==--==--==-
I believe the rest of what I wrote was accurate.

Hi, all:
When I use CygWin 3.17.1 to build Sun's CLDC 1.0.x, an error occurs:
../../src/check_class.c(30) : fatal error C1083: Cannot open include
file: 'ctype.h': No such file or directory
But the file "ctype.h" is right in the /usr/include, which has been set
in the $PATH.
Can some body help me out ?
Best Regards
Wu Kun
