This makes complete sense. Thank you! Dave

Dear Dave,

c::*ecl-include-directory* tells ECL where to find ECL's own header files. Likewise, c::*ecl-library-directory* is the location of the libecl.so.

For including your own header files, please use c:*user-cc-flags*, for example as

(setf c:*user-cc-flags* "-DWXUSINGDLL -IC:/Dave/wx/include -IC:/Dave/wx/include/msvc")

Additional linker flags and additional libraries to link in can be specified in c:*user-linker-flags* and c:*user-linker-libs* respectively, e.g.

(setf c:*user-linker-flags* "-LC:/Dave/wx/lib/vc_x64_dll" c:*user-linker-libs* "-lsome_shared_library")

Note that if you are running an ECL release older than 23.9.9, both types of linker flags belong in c:*user-ld-flags*, although that variable is now deprecated because it can lead to linker flags being put in the wrong position in the linker command line.

Best regards,

Marius Gerbershagen

I am trying to add directories for #include directives and for linking libraries. The below text is my make.lisp file for building my code:

(require 'cmp) (setf c:*user-cc-flags* "-DWXUSINGDLL") (setf c::*ecl-include-directory* "C:/Dave/wx/include,C:/Dave/wx/include/msvc") (setf c::*ecl-library-directory* "C:/Dave/wx/lib/vc_x64_dll") (compile-file "wx.lisp" :system-p t) (c:build-fasl "wx" :lisp-files '("wx.obj"))

Although

(setf c:*user-cc-flags* "-DWXUSINGDLL")

Is working as evidenced by the argument list to run-program, there is no evidence that the include or library directories are being used at all. Moreover, the #include directive in the wx.lisp code cannot find the specified header file.

How are c::*ecl-include-directory* and c::*ecl-library-directory* intended to be used?
