Joey, this is the article I was talking about. Haje

Topic:

Some Windows developers choose to use the Cygwin GCC port as their
compiler. This TechTip describes how to set up IDL so that CALL_EXTERNAL
works with GCC.

Discussion:

Several customers have reported success using CALL_EXTERNAL with
Cygwin's GCC Windows port instead of Microsoft Visual Studio.

a.. Create a new user environment variable (Control Panel ->
System -> Advanced -> Environment Variables) called IDL_DLM_PATH.
Set this to: C:\RSI\IDL61\bin\bin.x86;c:\cygwin\bin

b.. Set the following parameters on !MAKE_DLL:
1.. !make_dll.LD = 'c:\cygwin\bin\ld.exe -shared -o %L %O %X'
2.. !make_dll.CC = 'c:\cygwin\bin\gcc.exe
%X -fPIC -I"/cygdrive/c/RSI/IDL61/external/include" -c -D_REENTRANT %C -o
%O'
3.. !make_dll.COMPILER_NAME='GCC'
c.. To test, load and compile the STRING_ARRAY.PRO example in the
IDL61\external\call_external\C subdirectory.
IDL> string_array, 'Hello, Cygwin!', /VERBOSE

Calling string_array with:

STRARR_L STRING = 'Hello, Cygwin!'

Hello, Cygwin!

Result from string_array is:

RESULT STRING = 'Hello, Cygwin!'

If the PATH environment does not also include c:\cygwin\bin, users may
receive an error message that cygwin1.dll could not be found.
