I am new at uClinux and I am trying to cross-compile and link the following simple program (prova.c):
The host system is Suse 10.0, the toolchain is bfin-gcc-3.4-3.i386.rpm and, because I am using a rev 0.1 ezkit 537, the used distro is uClinux-dist-2005R3.tar.bz2 compiled disabling the instruction cache.
the used compiling string is:
"bfin-uclinux-gcc -L /home/sedekfx/Documents/blackfin/uClinux-dist/lib/libgmp/
-I /home/sedekfx/Documents/blackfin/uClinux-dist/lib/libgmp/ -Wl,-elf2flt prova.c -o prova" where in the "/home/sedekfx/Documents/blackfin/uClinux-dist/lib/libgmp/" directory there is the compiled libgmp.a lib. This lib was compiled by the make process of uClinux selecting the building process in the make menuconfig procedure.
Then I get the following error:
prova.elf2flt(.text+0x102): In function `_main':
/usr/src/packages/BUILD/bfin-gcc-3.4/../binutils/binutils-2.15/gcc/libgcc2.c: undefined reference to `___gmpz_init'
collect2: ld returned 1 exit status
how to properly link to gmp lib?
Many Thanks in advance

your software is crazy out of date. if you upgrade to 2009R1, things should work fine. i just looked at gmp in 2009R1 and it seems to work fine.
