Re: [Ecls-list] Embedding C++ code in LISP under Windows
Hi Juanjo,
Thank you!
It was too late in the night when I wrote this email to think clearly: I
tried to apply my experiences from embedding C++ code via the ECL FFI on my
Mac to Windows... Not a good strategy :)
In both cases I got the same error messages being caused by the compiler
misinterpreting the C++ code as C code.
In the case of my Mac recompiling ECL with '--with-cxx' was the solution.
On Windows, however, the problem is caused by 'asdf:make-build' generating
a file with the extension .c which makes the compiler interpreting the code
as C code. The command line option /TP can be use to force the compiler to
interpret the content of the file as C++ code. (See the page "/Tc, /Tp,
/TC, /TP (Specify Source File Type)" at
http://msdn.microsoft.com/en-us/library/032xwy55.aspx .)
Doing so a second error is thrown: error C4716: 'main_lib_CUBE' : must
return a value ('cube' is the name I called the library). The
option /wo4716 can be used to turn it into a warning resulting in the
library being built. (See "/w, /Wn, /WX, /Wall, /wln, /wdn, /wen, /won
(Warning Level)" at http://msdn.microsoft.com/en-us/library/thxezb7y.aspx )
Here my current solution which builds the library:
In my Makefile:
--- Makefile---
...
cube.lib: cube.asd cube.lisp Cube.obj
ecl -norc -load cube-build.lisp
...
---
The file with the LISP code used to build the library:
--- cube-build.lisp ---
(ext:install-c-compiler)
(require :asdf)
(push "./" asdf:*central-registry*)
(let ((COMPILER::*cc-flags* (concatenate 'string COMPILER::*cc-flags* " /TP
/wo4716 "))
(COMPILER::*ld-bundle-flags* (concatenate 'string
COMPILER::*ld-bundle-flags* " Cube.obj ")))
(asdf:make-build :cube :type :static-library :move-here "./cube.lib"))
(quit)
---
On the long term a better solution might be
- to add some option to 'asdf:make-build' which takes either ':c' or
'cpp' as value (with ':c' being the derault) and generates a file with the
respective extension;
- to change the LISP to C / C++ compiler so that the generated function
'main_lib_NAMEOFLIBRARY' actually returns a value.
Thanks for you help,
Dietrich

Probably my misconfiguration or quicklisp issue. Seems that the quicklisp loaded older version of trivial-garbage which didn't include ECL support. Removed all local trivial-garbage dists and reloaded it and everything seems to work.

[Ecls-list] ECL doesn't support weak key hash-tables?
Hi, When trying to load cl+ssl via quicklisp it raises error that ECL doesn't support weak key hash tables. Problem seems to be raised in trivial-garbage. Here's quick way to replicate this: (ql:quickload 'trivial-garbage) CL-USER> (ql:quickload 'trivial-garbage) To load "trivial-garbage": Load 1 ASDF system: trivial-garbage ; Loading "trivial-garbage" (TRIVIAL-GARBAGE) CL-USER> (defvar *threads* (trivial-garbage:make-weak-hash-table :weakness :key)) ; Evaluation aborted on #.
