[Chicken-users] repository pathname, location and customisation, lib64
Ciao,
I would really like to customise the location of the installed eggs
for my Slackware64 on a x86_64-pc-linux-gnu running Chicken 5.0.0.
First I go to the Wiki[1] and try this:
$ csi -p "(repository-path)"
Error: unbound variable: repository-path
Call history:
(##core#begin (##core#require library scheme#)
(##core#require library chicken.base#) (##core#requir...
(##core#require library scheme#)
(##sys#load-library (##core#quote library))
(##core#quote library)
(##core#require library chicken.base#)
(##sys#load-library (##core#quote library))
(##core#quote library)
(##core#begin (##core#require expand chicken.syntax#))
(##core#require expand chicken.syntax#)
(##sys#load-library (##core#quote expand))
(##core#quote expand)
(##sys#load-library (##core#quote library))
(##sys#load-library (##core#quote library))
(##sys#load-library (##core#quote expand))
(repository-path)
(repository-path) <--
but I read, and see on my system, that the directory is
"${prefix}/lib/chicken/9".
Under Slackware 32-bit the libraries' directory is "$prefix/lib",
while underSlackware 64-bit the libraries'directory is
"$prefix/lib64". On a 64-bit platform: it is possible to install both
32-bit and 64-bit packages and their files go into different
installation directories. It is not right to put everything under
"lib", I would like to use "lib64".
Searching the Wiki, the bugs database and the mailing list archive: it
seems that this is not currently supported? But in some old messages,
someone *is* using "lib64"...
TIA

Re: [Chicken-users] is the readline egg dead?
Hi all, there is a very easy to use and simple alternative to readline and consorts: rlwrap It's an external package and thas has the advantage to be usable not only with chicken, but with every program without readline support.

[Chicken-users] Announce: Hypergiant and OpenGL eggs are available for CHICKEN 5!
Hello CHICKEN users! Today I finished porting and publishing the last eggs of the OpenGL suite! I am now the maintainer of the CHICKEN 5 version of the following eggs, which are, as of today, all available from chicken-install: - epoxy - soil - glfw3 - gl-math - gl-utils - gl-type - glls - noise - hyperscene - hypergiant Compared to CHICKEN 4, the only opengl binding that remains is a new egg called `epoxy`. It’s a drop-in replacement for the old `opengl-glew` egg (except for the `init` procedure that is no longer required). Epoxy also provides the OpenGL ES APIs as well as the fixed-pipeline API that was previously available with the `opengl` egg. This new egg requires the epoxy library to be installed on the system. My plans for the near future are to update support for OpenGL ES in the high level libraries (hypergiant and co.) so that it’s a runtime option instead of a compile-time one. I also plan to make a sound library and integrate it into hypergiant. I hope all of this will be useful! If you experience any problem, feel free to contact me! Have a great day! :D ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
Re: [Chicken-users] NULL in calls to C functions with bind
Hi Christoph, I think that NULL should be correct and work - since you're creating a pointer object to address 0. However, the FFI has a convenience for null-pointers: you can pass in #f instead. That's easier and requires one less GC object. It's mentioned in the manual on c-pointer foreign type: http://wiki.call-cc.org/man/5/Foreign%20type%20specifiers#pointers That takes me to my personal experience which I want to share: when creating foreign bindings, just use foriegn-lambda and skip the bind dependency. Maybe when you have huge API's, bind can save you some time. But I'd say that hand-written foreign-lambdas give you more control of what's going on, force you to think about every function and make sure it's safe and generally produce better interfaces. I hope this may give you some pointers. K.

Re: [Chicken-users] is the readline egg dead?
Hello Kristian, > I don't know about the status on the C4 readline egg, whether a C5 port is > planned or whether it's considered obsolete. I've contributed to the readline egg before and eventually reached the conclusion that I'm better off developing my own with a different, incompatible API. I've also contacted its author regarding plans with a C5 port and received no reply whatsoever. For this reason I published my version under the name breadline for C5, to show that it's a completely different thing.

Re: [Chicken-users] is the readline egg dead?
Hi Marco, It seems the readline egg isn't available for CHICKEN 5. You could try [breadline] or [linenoise]? [breadline]: http://wiki.call-cc.org/eggref/5/breadline [linenoise]: http://wiki.call-cc.org/eggref/5/linenoise I don't know about the status on the C4 readline egg, whether a C5 port is planned or whether it's considered obsolete.
