Re: Makefile quits generating nothing

Thanks Jeff :),

That worked to some extent and exited giving the error 

/usr/include/bits/types.h:187: error: conflicting types for ÃâË__loff_tÃââ
/home/stangeda/newlib_08022010/newlib-1.18.0/newlib/libc/include/machine/types.h:22:

So i understand that types.h is being called twice from two different
locations, to overcome this i compiled fom the directory 
/home/stangeda/newlib_08022010/newlib_compile/i686-pc-linux-gnu/newlib/libc/argz/
using  -nostdinc command in commandline

gcc
-I/home/stangeda/newlib_08022010/newlib_compile/i686-pc-linux-gnu/newlib/targ-include
-I/home/stangeda/newlib_08022010/newlib-1.18.0/newlib/libc/include
-DPACKAGE_NAME=\"newlib\" -DPACKAGE_TARNAME=\"newlib\"
-DPACKAGE_VERSION=\"1.18.0\" "-DPACKAGE_STRING=\"newlib 1.18.0\""
-DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1
-DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1
-DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1
-DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" -I.
-I../../../../../newlib-1.18.0/newlib/libc/argz -Wall
-D_I386MACH_ALLOW_HW_INTERRUPTS -DHAVE_FCNTL -DHAVE_GETOPT -fPIC
-D_I386MACH_NEED_SOTYPE_FUNCTION  -nostdinc -DMISSING_SYSCALL_NAMES
-fno-builtin -g -O2 -c
../../../../../newlib-1.18.0/newlib/libc/argz/argz_add.c  -fPIC -DPIC -o
.libs/argz_add.o

I tried to see if it successfully compiles with nostdinc flags..but that
didnt work quite well since it was missing few files. The first error it
produced was

/home/stangeda/newlib_08022010/newlib_compile/i686-pc-linux-gnu/newlib/targ-include/sys/_types.h:25:20:
error: stddef.h: No such file or directory

So i understand few files are being called twice and when i use -nostdinc
there are other files missing. Could you throw some light on this scenario.

Thanks,
Sravs
