Hi I'm running Debian squeeze with intel composer compiler for fortran and c. Now Im trying to install the zlib libray, but when Im configuring it , I got this:

./configure --prefix=/dados/curso/lib/zlib-1.2.5

Checking for shared library support...
Tested icc -w -c -O ztest31822.c
Tested cc -shared -O -o ztest31822.so ztest31822.o
/usr/bin/ld: ztest31822.o: relocation R_X86_64_PC32 against undefined symbol `getchar@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
No shared library support; try without defining CC and CFLAGS
Building static library libz.a version 1.2.5 with icc.
Checking for off64_t... Yes.
Checking for fseeko... Yes.
Checking for unistd.h... Yes.
Checking whether to use vs[n]printf() or s[n]printf()... using vs[n]printf().
Checking for vsnprintf() in stdio.h... Yes.
Checking for return value of vsnprintf()... Yes.

What is the real problem?, How could I follow the directions:
"recompile with -fPIC" and "try without defining CC and CFLAGS"?

Thanks in advance!
