Hi 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

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

following..

Thanks
