[Insight-users] Re: install itk under cygwin

[Quan Chen]

I found the problem.  When I install cygwin, I only have bash.exe installed,
I don't have sh.exe.  It seems that some scripts the cmake is running
requires sh to exist.  So I just copied bash.exe to sh.exe and it worked. I
am wondering if either itk or cmake can add a check of whether sh exists or
not to prevent such issue happening.
Now, I can get it to work with gcc and g++ (export CC=/bin/gcc.exe; export
CXX=/bin/c++.exe) under cygwin.  However, now I try to use the intel
compiler under cygwin (I used intel compiler under windows with visual
studio .net and it worked).  My intel compiler is installed under program
file and I created a link in the /bin/ directory.  I did export
CC=/bin/icl.exe and export CXX=/bin/icl.exe, however when I configure
ccmake, I got the error that icl unable to compile a simple program.  The
error message is included in the following, anybody have a clue?

 The C compiler "/bin/icl.exe" is not able to compile a simple test program.
 It fails with the following output:
  /bin/make -f CMakeFiles/cmTryCompileExec.dir/build.make
