problem of linking libraries with GC_MALLOC

[jitender001001@gmail.com]

hi all
I have a problem of linking static libraries with GC_MALLOC, I
have made my routine smaller to make it simpler. I m using fedora 7
kernel version 2.6.18-1.2798.fc6

void
str_check_alloc ( char **str, int required, int size)
{
int init_reqd, space2alloc;
if( size == 0) {
init_reqd = 1;
space2alloc = required;
}
else {
init_reqd = 0;
space2alloc = size*2;
}

if (init_reqd) {
*str = GC_MALLOC(space 2alloc);
(*str)[0] = '\0';
} else
*str = GC_REALLOC(*str , space2alloc);
}

name of main program is "test_toupper.c " which calls this routine
"str_check_allo c" internally.
i m extracting executables in "test_toupp er"

gcc -static -g -DINLINE= -I../../../install/include test_toupper.c -
L../../../install/lib -lgc -lsvcr -lm -o test_toupper

.../../../install/lib/libsvcr.a(libsv cr_a-str.o): In function
`str_check_allo c':
/work/anonymous/svc/libsvcr/str.c:47: undefined reference to
`GC_realloc'
/work/anonymous/svc/libsvcr/str.c:44: undefined reference to
`GC_malloc'



I have added "gc.h" library also but still it is showing undifined
reference to GC_MALLOC
what can be the problem.

Wrong group, try a Linux one.

This is referring to a reference to GC_realloc in libsvcr. Your
own code doesn't use GC_realloc, it uses GC_REALLOC (unless
that's a macro referring to GC_realloc).

This doesn't exist in standard C, and is thus off-topic. I don't
know where you should go, but it's not here.
