Stefan, Sorry, I should have clarified that I am using the tools.conf already to set the compiler prefix to the right compiler. Still didn't help ;-( Daniel

Hi Stefan, I didn't realize that the linux_x86 would build with the 64bit compiler.
in fact, it doesn't chooses the compiler, but which include pathes and assembler-files to use. The build-system simply uses the compiler found at '/usr/local/genode-gcc/bin/genode-x86-...' by default, and uses its default target. So if you have installed a compiler, which targets only 32bit or 64bit, of course you can only build for that platform.
Unfortunately, our 'toolchain'-script produces a compiler, that only targets the underlying platform, and not both (the pre-compiled version targets 32bit only). We'll fix that issue, and thereby use -m<arch> switches for building Genode to circumvent such problems in the future.
By now, a preliminary solution for you might be to install both compiler variants, and tell Genode's build-system which compiler to use, by overriding the following variable in 'etc/tools.conf':
CROSS_DEV_PREFIX = /usr/local/genode-gcc/bin/genode-gcc-
By stating compiler and spec-variables explicitly, you should be able to build all platforms in the same environment.
Regards Stefan
This now works fine on a 64bit host. However, I couldn't get the 32bit compiler to work with your suggested SPECS flags though - it still trys to compile the 64bit version.

Hi Stefan, Good news is that the x86_64 build seemed to work. Bad news is that it *may* have broken the linux_x86 build...see below. You might want to check this yourself.
I don't think this has something to do with the 64-bit patch for Fiasco.OC.
I guess you tried to build Genode's Linux version on a 64-bit system with Gendode's 32-bit toolchain.
The Genode build system uses some heuristic to determine which Linux version to build for you, by analyzing the underlying system, so it tries to build a 64-bit version for you, while using a compiler targeting 32-bit. To circumvent this heuristic, you can explicitly state in the 'etc/specs.conf' to build the 32-bit version:
SPECS = genode linux_x86_32 sdl
or change the compiler to target 64bit.
I hope that helps.
Best regards. Stefan
Thanks Daniel

-----Original Message----- From: Stefan Kalkowski [mailto:stefan.kalkowski@...1...] Sent: Thursday, March 10, 2011 5:38 AM To: genode-main@lists.sourceforge.net Subject: Re: 64bit Genode and Fiasco.OC
Hello Daniel,
Now, the Fiasco.OC/Genode variant is 64-bit ready. Please, checkout the last revision from our subversion repository. You need to create a new build-directory with the 'create_builddir' tool. There are new platform-specifications available to it, namely: 'foc_x86_32' and 'foc_x86_64'.
Alternatively, you might place a 'specs.conf' file in the 'etc' directory of an existing Fiasco.OC/Genode build-directory, and put the following line into it:
SPECS = genode foc_x86_64
Moreover, you've to build a 64-bit version of a Genode-compliant gcc by yourself. This is simply done by executing, the 'toolchain' script in Genode's 'tool' directory:
toolchain all
This will build gcc for 64-Bit (when executed in 64-bit Linux). You have to install MPFR, GMP, MPC, PPL, and CLooG development libraries beforehand. The resulting tool-chain gets installed at '/usr/local/genode-gcc'.
I hope that helps.
Best regards Stefan

Hi,
Is Genode+Fiasco.OC x86_64 known not to work? After various fiddling about with include files, and –m64 flags I got as far as the
