cannot compile bash or net-snmp

[Altera_Forum]

Hi, 

 I am trying to compile bash with the latest uClinux toolchain, but I get an error when trying to link the libraries:  nios2-linux-uclibc-gcc -L./builtins -L./lib/readline -L./lib/readline -L./lib/glob -L./lib/tilde -L./lib/malloc -L./lib/sh -O2 -g  -Dlinux -D__linux__ -Dunix -D__uClinux__ -DEMBED   -I/home/amir/uClinux-dist -I/home/amir/uClinux-dist/include -fno-builtin -Dfork=vfork -D__adjtimex=adjtimex -Wl,-d -Wl,-elf2flt -L./lib/termcap  -rdynamic  -O2 -g  -Dlinux -D__linux__ -Dunix -D__uClinux__ -DEMBED   -I/home/amir/uClinux-dist -I/home/amir/uClinux-dist/include -fno-builtin -Dfork=vfork -D__adjtimex=adjtimex -I./lib/termcap -o bash shell.o eval.o y.tab.o general.o make_cmd.o print_cmd.o  dispose_cmd.o execute_cmd.o variables.o copy_cmd.o error.o expr.o flags.o jobs.o subst.o hashcmd.o hashlib.o mailcheck.o trap.o input.o unwind_prot.o pathexp.o sig.o test.o version.o alias.o array.o braces.o bracecomp.o bashhist.o bashline.o siglist.o list.o stringlib.o locale.o findcmd.o redir.o pcomplete.o pcomplib.o syntax.o xmalloc.o -lbuiltins -lsh -lreadline -lhistory ./lib/termcap/libtermcap.a -lglob -ltilde -lmalloc  -L/home/amir/uClinux-dist/lib -L/home/amir/uClinux-dist/lib/libnet -L/home/amir/uClinux-dist/lib/libdes -L/home/amir/uClinux-dist/lib/libaes -L/home/amir/uClinux-dist/lib/libpcap -L/home/amir/uClinux-dist/lib/libssl -lcrypt -lutil -lc nios2-linux-uclibc-gcc: unrecognized option `-rdynamic' sh ./mkconfig > .config.tmp bash.elf2flt(.text+0x58360): In function `tgetent': /home/amir/uClinux-dist/user/bash/lib/termcap/termcap.c:734: undefined reference to `bcopy' bash.elf2flt(.text+0x5860c): In function `tparam1': /home/amir/uClinux-dist/user/bash/lib/termcap/tparam.c:166: undefined reference to `bcopy' collect2: ld returned 1 exit status  Similarly, with net-snmp, I get the following error:  nios2-linux-uclibc-gcc -O2 -g  -Dlinux -D__linux__ -Dunix -D__uClinux__ -DEMBED   -I/home/urna/uClinux-dist -I/home/urna/uClinux-dist/include -fno-builtin -Dfork=vfork -D__adjtimex=adjtimex -shared  snmp_client.lo mib.lo parse.lo snmp_api.lo snmp.lo snmp_auth.lo asn1.lo md5.lo snmp_parse_args.lo system.lo vacm.lo int64.lo read_config.lo snmp_debug.lo tools.lo snmp_logging.lo snmpv3.lo lcd_time.lo keytools.lo scapi.lo callback.lo default_store.lo snmp_alarm.lo data_list.lo oid_stash.lo mt_support.lo snmp_enum.lo snmp-tc.lo snprintf.lo strlcpy.lo strtol.lo strtoul.lo strtok_r.lo snmp_transport.lo snmpUDPDomain.lo snmpTCPDomain.lo snmpUnixDomain.lo snmpCallbackDomain.lo snmp_secmod.lo snmpusm.lo snmp_version.lo check_varbind.lo container.lo container_binary_array.lo container_null.lo container_list_ssll.lo container_iterator.lo cmu_compat.lo ucd_compat.lo   -Wl,-soname -Wl,libnetsnmp.so.5 -o .libs/libnetsnmp.so.5.2.1 nios2-linux-uclibc-gcc: unrecognized option `-shared' if cmp -s .config.mkconfig .config.tmp;        then                rm -f .config.tmp;        else                make clean;                mv -f .config.tmp .config.mkconfig;        fi make: Leaving directory `/home/amir/uClinux-dist/user/busybox' /opt/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/lib/crt1.o(.text+0x10): In function `_start': : undefined reference to `main' /opt/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/lib/crt1.o(.text+0x14): In function `_start': : undefined reference to `main' collect2: ld returned 1 exit status  However, I have set net-snmp to build as a static library in the configuration (make menuconfig). The only application I am building is snmpget.  In the Kernel/Library/Defaults section of the configuration, is Libc Version still allowed to be "None"?  Is there some extra patching that needs to be done to either of these applications before thay can be compiled for uClinux?  Thanks.  - Amir

1. you need to add "#include <strings.h>" in the source for bcopy. 

2. you need to modify the Makefile to remove .so targets.

The forum seems to have lost everything after 2007 and I had to remake my login?
