Or at least further than the following shows: http://sourceforge.net/p/genode/discussion/825067/thread/2177b474/ Sorry .... I am still very new to this....:-(. -- Regards, Peter Teoh

I know this is not the recommended platform, but I don't have any existing 12.04 lying around. Is there any patches possible? If someone can provide some guidelines, I can help with creating the patches. Similarly, for ports, "make prepare" gives: /home/tthtlc/Downloads/genode/repos/ports/ports/gcc.port:19: *** Need to have 'autoconf2.64' installed..

Hello. I am updating old scripts to the latest version of Genode and have problem with make prepare. I have well working (in past) port file, but when I make «make prepare» now I see: [k@...233... newports]$ make prepare PKG=nginx bash: line 0: test: <..>/contrib/nginx-f26242e3bb7c06c88134e5bb2faec65b8e0aafc9: binary operator expected bash: line 0: test: <..>/contrib/nginx-f26242e3bb7c06c88134e5bb2faec65b8e0aafc9: binary operator expected mv: target ‘99f6702d998b775c0039e4666b08bacc577a6787.incomplete’ is not a directory ../../tool/ports/prepare_port:46: recipe for target '_install_in_port_dir' failed make[1]: *** [_install_in_port_dir] Error 1 ../../tool/prepare.mk:36: recipe for target 'prepare-nginx' failed make: *** [prepare-nginx] Error 2 after that I see directory «99f6702d998b775c0039e4666b08bacc577a6787» in my repository directory. But when I rename port file from nginx.port to nginx2.port the «make prepare» command works well… -- Vasily A. Sartakov sartakov@...104...

Framebuffer
by chirag garg 12 Feb '15

12 Feb '15

Hi all, I was trying to understand the flow of framebuffer flow for given imx53 code in the following directory repos/os/src/drivers/framebuffer/imx53/main.cc In the main function, one static variable "session_component" has been created which uses the "config_attribute" function defined in line number 115 which expect a config file in build process. What is the need of this config file with respect to framebuffer and where should i found this config file in the repository because when i run the framebuffer script it is not able to open config file?

Deployment of upstream library sources
by Roman Iten 09 Feb '15

09 Feb '15

Hi, we need a way to provide upstream library sources (i.e. the "contrib"-directory) in an environment without internet access. In order to make this task reasonably comfortable, I miss three features in the prepare tool: 1. Similar to "make -C ./build ...", "make prepare -C ./build" will download all upstream sources required by the corresponding build.conf file. 2. "make prepare ... --download-script download.sh" won't download anything, but instead creates a script file which can be transferred to a PC connected to the internet. There you can execute the script in order to download the sources. The download directory can then be transferred into the offline environment. 3. "make prepare ... --unpack [/path/to/download_dir]" unpacks the downloaded upstream libraries to the local contrib directory. What do you think? Is something like this possible? Or do you have any other ideas/suggestions? Regards Roman
