I'm not sure if you mentioned it, but in the Gentoo system very easy
create cross-platform environment.
1) emerge -v crossdev
for example
2) crossdev -S armv7a-unknown-linux-gnueabi
and kernel compilation.
3) make ARCH=arm CROSS_COMPILE="armv7a-unknown-linux-gnueabi-"

Re: [Haifux] What are the car arrangements these days?
It's really sad to hear it right now. Why did you say me nothing last lecture? How am I suppose to know about this type of "bugs" ? Anyway I talked again with security office and they claim what all fax were sent last time. And they sent it again today to the main gate. Just ask the guardians to recheck their papers they received from Kabat's office. > Well, let's be frank. I tried the trick last time.

[Haifux] Entry Permission Form
Hello again, As a follow up to previous mail, I talked with Kabat's office and they suggested new way of our communication. Instead registration, they agreed to allow vehicle entry to everyone coming to lecture without any registration. The problem is that we need provide schedule for a number of weeks before with their agenda. Is it possible to us be more responsible with schedule ? -- Leon Romanovsky - "Change is inevitable; progress is optional". ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Hi,
This will work only for permanent audience, and I'm trying to allow it
for everyone, especially for one-time guests.

Re: [Haifux] Entry Permission
My goal is to allow to everyone who will want hear lecture the possibility to enter into Technion as a people do. Especially for everyone who doesn't want come to every lecture. Talk with Zvi(http://haifux.org/lectures/163/), and ask him how "easy" was to allow entry permission to one time guests. And now imagine that someone from undergraduate or industry will try to organize it. I want that it will work without need of any "kombinot".

Re: [Haifux] Entry Permission
Thanks. I think that the preferred way is to review report before sending. There is more unnecessary complexity to require users register and after that trying to secure the data (you know there are bad people everywhere).

[Haifux] Entry Permission
Hi, I talked with Amos (Technion's kabat) and he agreed to allow entrance for haifux audience with vehicles. His requirements are very simple: 1) Limit entry permission only to non-student (Right now we don't need to think about, because we are small group). 2) Fax him report with ID, name and vehicle ID before lecture. It will work only as a group, there is NO need to send one by one. We need volunteers that will write the following modules: 1) Online registration form 2) Report compilation module 3) (If it possible) Report->Fax sending module (I can donate FAX-modem). 4) Status information for administrator via email. -- Leon Romanovsky - "Change is inevitable; progress is optional".

Re: [Haifux] Lecture regarding the open source compiler FPC
It will be nice to hear and see advantages of OP over well known languages (C/C++) ik wrote: Hello, I wish to give an "about" lecture regarding the open source compiler FPC. The presentation/lecture itself called: "FPC - Beyond the myths, when clearing the fog." This lecture is about giving different aspect regarding Object Pascal, and it's uses. It is made for people that have knowledge in other programming languages such as C, C++, Java (others as well). The presentation gives different aspects then you would expect from regular "high-school/universities" material, and gives a really small glance regarding the real capabilities of the Object Pascal language, and FPC. So I wish to know if there is any audience that will be willing to hear such presentation (I guarantee you some surprises and unexpected information about the language and compiler). Thanks, Ido
