firstly , remove the stderr sending null and lets see what happen
probably , error occurs due to another things,maybe variables (be sure all variables is defined like TMPC,TMPO..)
and you can try with this (more specific)
Code:
.......
cat > $TMPC << EOF
#include<stdio.h>
#include <zlib.h>
#include <string.h>
int main( void ) {
static const char* curV = ZLIB_VERSION;
if (zlibVersion()[0] != curV[0]) {
printf("zlib versions has major different using..%s and,currently in system..%s\n" ,zlibVersion(),ZLIB_VERSION);
return 1;}
else if ( strcmp (zlibVersion(),ZLIB_VERSION) != 0 ) {
printf( "you are using %s, cur version %s.\n",zlibVersion(),ZLIB_VERSION);
}
return 0;
}
EOF

unset
unset(n) Tcl Built-In Commands unset(n)
__________________________________________________________________________________________________________________________________________________NAME
unset - Delete variables
SYNOPSIS
unset ?-nocomplain? ?--? ?name name name ...?
_________________________________________________________________DESCRIPTION
This command removes one or more variables. Each name is a variable name, specified in any of the ways acceptable to the set command. If
a name refers to an element of an array then that element is removed without affecting the rest of the array. If a name consists of an
array name with no parenthesized index, then the entire array is deleted. The unset command returns an empty string as result. If -nocom-
plain is specified as the first argument, any possible errors are suppressed. The option may not be abbreviated, in order to disambiguate
it from possible variable names. The option -- indicates the end of the options, and should be used if you wish to remove a variable with
the same name as any of the options. If an error occurs, any variables after the named one causing the error are not deleted. An error
can occur when the named variable does not exist, or the name refers to an array element but the variable is a scalar, or the name refers
to a variable in a non-existent namespace.
EXAMPLE
Create an array containing a mapping from some numbers to their squares and remove the array elements for non-prime numbers:
array set squares {
1 1 6 36
2 4 7 49
3 9 8 64
4 16 9 81
5 25 10 100
}
puts "The squares are:"
parray squares
unset squares(1)squares(4)squares(6)
unset squares(8)squares(9)squares(10)
puts "The prime squares are:"
parray squares
