[Live-devel] Compilation under uClinux

[Arthur Shipkowski]

Greetings,

I have been attempting to get the live.com distribution from 8/26 to compile
as part of the uClinux distribution. (The new-as-of-yesterday version didn't
appear to have a compelling reason for me to grab it immediately.)

I have generated the below config.uClinux:
COMPILE_OPTS =
     $(INCLUDES) -I. -O2 -DSOCKLEN_T=socklen_t -D_LARGEFILE_SOURCE=1
C =         c
C_COMPILER =        $(CC)
CFLAGS +=       $(COMPILE_OPTS)
C_FLAGS = $(CFLAGS)
CPP =           cpp
CPLUSPLUS_COMPILER =    $(CXX)
CPLUSPLUS_FLAGS =   $(COMPILE_OPTS) -Wall -DBSD=1
CPLUSPLUS_FLAGS += $(CPPFLAGS) -fexceptions
OBJ =           o
LINK =          $(CXX) -o
LINK_OPTS =     -L. $(LDFLAGS)
CONSOLE_LINK_OPTS = $(LINK_OPTS)
LIBRARY_LINK =  $(AR) cvrs
LIBRARY_LINK_OPTS =
LIB_SUFFIX =            a
LIBS_FOR_CONSOLE_APPLICATION = $(CXXLIBS)
LIBS_FOR_GUI_APPLICATION = $(LIBS_FOR_CONSOLE_APPLICATION)
EXE =

Unfortunately, when it gets to compiling the test programs, I get the below:

I tried changing the linker to use m68k-elf-ld to perform the link rather
than m68k-elf-g++; after more tweaking (the uClinux distribution seems to
assume by default that you want to use gcc or g++ to do your link stage), I
received the same result.  I also tried compiling with shared libraries on
and off.  I'm compiling using the 20030314 elf-tools from uclinux.org
(m68k-elf-gcc 2.95.3 with patches), as everything else I use (2.4.x Linux
kernel, etc) works with that.

Any suggestions?  I'm afraid it's something quite obvious, but
libUsageEnvironment.a is theoretically being linked above.

I did see that some of you had gotten it running under uClinux, so if you
could offer your configuration files it might be helpful.

Thank you all for your time.
