nanogui: Thread: linking nano-x problem

Hi,

I'm trying to compile the newest version of microwindows for uClinux 
(running on a microblaze CPU)
I've entered a new section into the Arch.rules section to allow selection of 
uClinux:

ifeq ($(ARCH), LINUX-UCLINUX)
COMPILER = gcc
CXX_COMPILER = g++
TOOLSPREFIX = $(MICROBLAZETOOLSPREFIX)
DEFINES += -DLINUX=1 -DUNIX=1
CFLAGS +=  $(GCC_WARNINGS) $(OPTFLAGS)
LDFLAGS += -lc
endif

The first part of the control file looks like this:

# note: ELKS can't build client/server nano-X, nor widget lib
#
####################################################################
ARCH                     = LINUX-UCLINUX

ARMTOOLSPREFIX           = arm-linux-
MIPSTOOLSPREFIX          = mipsel-linux-
POWERPCTOOLSPREFIX       = powerpc-linux-
SHTOOLSPREFIX            = sh-linux-gnu

---cut---------

By when nano-x is being linked I get a loadfull of undefined references, 
which looks like it's not linking in libc.a But notice that there is a -lc 
linker option on the command line.
The C library is uClibc. The dir. where libc is is also given on the command 
line ( -L/home/fn/uClinux-dist/lib/uClibc/lib the contents of which is: 
crt0.o  crt1.o  libc.a  libcrypt.a  libm.a  libnsl.a  libresolv.a 
libutil.a). What could be wrong / does this ring a bell ??

Compile/link output given below.

Thanks

Finn

It appears that the -lc is in the link command line before
the *.o files.  Perhaps you should remove -lc from LDFLAGS
and have gcc insert it automatically.

Hi all,

 

Is there any patch file to be included while compiling microwindows in
uclinux distribution?

I am using 2.4 kernel with nisa-elf toolchain.

 

Warm regards

Marshia
