Installation issues

Subversion client

When I compile soclib platforms, I get the following types of error:

soclib/soclib/lib/elf_file_loader/src/elf_file_loader.cpp:40:23: error: dpp/foreach: File or directory not found
soclib/soclib/lib/elf_file_loader/src/elf_file_loader.cpp:42:24: error: elfpp/object: File or directory not found
soclib/soclib/lib/elf_file_loader/src/elf_file_loader.cpp:43:24: error: elfpp/symbol: File or directory not found
soclib/soclib/lib/elf_file_loader/src/elf_file_loader.cpp:44:25: error: elfpp/section: File or directory not found

You probably use a Subversion client that does not understand svn:externals directives (see Therefore, the checkout you did on SoCLib's repository is incomplete. Please, try with a "vanilla" subversion client instead.

OS version misdetection

Linux 64 bits is misdetected most of the time, in SystemC configuration section in soclib/utils/conf/soclib.conf, change

   os = _platform(),


   os = 'linux64',

Python version

Traceback (most recent call last):
line 32, in ?
    from soclib_cc.builder.cxx import CxxCompile
line 29, in ?
    import action
line 79
SyntaxError: invalid syntax

Please update to python-2.4

Utilities compilation going wrong

When I try to compile the Soclib tools I get the following error:

make[1]: Entering directory `/lip6/soclib/utils/src/pipe2fb'
make[1]: Nothing to be done for `Makefile'.
make[1]: Leaving directory `/lip6/soclib/utils/src/pipe2fb'

It looks like you have the TARGET_ARCH environment variable set. Make is doing some silly replacements when it is set. Unset it and try again:

$ make

BFD using symbols from libiberty

Lots of errors like

/usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../lib64/libbfd.a(archures.o)(.text+0x3e0): In function `bfd_default_scan':
: undefined reference to `_sch_istable'

can be solved with


at the end of ~/.soclib/global.conf

Cross-compilation issues

Wrong cross-compiler

In a bunch of GCC error messages, you see

as: unrecognized option `-EL'

Your mips gcc has been created wrongly, it's using your native (most probably x86) assembler.

This is most probably because you configured binutils and gcc with different --prefix= options.

Recreate your cross-compilation toolchain.

Simulation issues

Bus simulation and multiple drivers

Using PiBus under SystemC-2.2, you see

Error: (E115) sc_signal<T> cannot have more than one driver
 signal `pibus_d' (sc_signal)
 first driver `tty_wrapper.port_8' (sc_inout)
 second driver `multiram_wrapper.port_8' (sc_inout)
 In file: ../../../../src/sysc/communication/sc_signal.cpp:137

SystemC got picky about multiple drivers. This probably needs a fix in simulation models, using SystemC-2.1 is a workaround for now.
