hi
i have been trying to build a dos->linux cross-compiler for the past few days. As a reference, i am following the article:
Linux x86 Host Cross Compiler HOWTO for the DJGPP Target Revised by Charles Wilkins Nov 14 2002
......which is present in the how to repository of the djgpp homepage.
the files i am using are the following:
binutils-2.16.tar.gz, djcrx203.zip, gcc400s2.zip, gcc-4.00.tar.gz
i have been able to build the binutils, however, the gcc-build gets stuck at an 'undefined reference' to a function called "_fixpath()".
I came to know that _fixpath() is a library function of libc for djgpp. So I tried putting the library libc.a into some directiry and making a small change in the corresponding makefile (packages/cross/gnu/gcc-4.00-obj/gcc/Makefile) - the one which generates this error - so that it explicitly reads the libc.a in the gcc command. This can be seen below as the last argument of the gcc command. However, inspite of this i am getting the "undefined reference" error.
make[1]: Entering directory `/home/sriram/kishore/packages/cross/gnu/gcc-4.00-ob
j/gcc'

../../gcc-4.00/gcc/prefix.c:346: undefined reference to `_fixpath'
collect2: ld returned 1 exit status
make[1]: *** [cc1.exe] Error 1
make[1]: Leaving directory `/home/sriram/kishore/packages/cross/gnu/gcc-4.00-obj
/gcc'
make: *** [all-gcc] Error 2
Anyways, the makefile should be able to read the library even if i dont make the above modification in the makefile - as i have followed the above article step by step and the libc.a file is already in the directory where it is supposed to be, according to the tutorial.
Somebody please help fast as this is urgent.
Thanx for ur time
kishore
