make: *** [webs] 错误 1

[alex@localhost LINUX]$

I think maybe my makefile is worng,

CFLAGS = -DWEBS -DUEMF -DOS="LINUX" -DLINUX -Dfork=vfork -D__uClinux__ $(UMSW) $(DASW) $(SSLSW) $(IFMODSW)

OTHERS = -DB_STATS -DB_FILL -DDEBUG

DEBUG = -g -Wall

IFLAGS = -I..

LDFLAGS = $(SSLLIB) $(IFMODLIB) -nostdlib -Wl,-elf2flt="-s 16000" -Wl,-v -Wl,-d

who can help me? thanks a lot.

    Alex,

    Remove the "-nostdlib" from LDFLAGS.

    We don't need "-nostdinc" and "-nostdlib", because they are defualt to uClibc when we do builtroot.

    hi:

    The app source code have a misc.c.

    In the file define : "static int strnlen(char_t *s, unsigned int n);"

    but nios2-uclibc previous declaration it.

    nios2-linux-uclibc-gcc -c -o ../misc.o -g -Wall -DWEBS -DUEMF -DOS="LINUX" -DLINUX -Dfork=vfork -D__uClinux__ -DUSER_MANAGEMENT_SUPPORT -DDIGEST_ACCESS_SUPPORT -I.. ../misc.c

    ../misc.c:61: error: conflicting types for 'strnlen'

    /home/alex/buildroot/build_nios2/staging_dir/bin-ccache/../lib/gcc/nios2-linux-uclibc/3.4.5/../../../../nios2-linux-uclibc/sys-include/string.h:254: error: previous declaration of 'strnlen' was here

    ../misc.c:61: error: conflicting types for 'strnlen'

    /home/alex/buildroot/build_nios2/staging_dir/bin-ccache/../lib/gcc/nios2-linux-uclibc/3.4.5/../../../../nios2-linux-uclibc/sys-include/string.h:254: error: previous declaration of 'strnlen' was here

    make: *** [../misc.o] 错误 1

    [alex@localhost LINUX]$

    Then I commented the define and funcntion in misc.c

    //static int strnlen(char_t *s, unsigned int n);

    /******************************************************************************/

    /*

    * Return the length of a string limited by a given length

    */

    //static int strnlen(char_t *s, unsigned int n)

    //{

    // unsigned int len;

    // len = gstrlen(s);

    // return min(len, n);

    //}

    Then I make again. Make success.

    But I worry about I comment it is not correct.
