compiling zlib-1.2.11 for SunOS 5.11-SPARC 64 bit.

[hicham65]

I want to generate 64bit library.

It seems the command below builds for 32 bit.

CC="cc -D_REENTRANT -D_TS_ERRNO -D_XPG_4_2" CFLAGS="-Xa -xO4"\
    ./configure --shared --prefix=$zlib_install_dir 

The usage below shows I can pass the [--64], is this the way to do it?

configure -help usage: configure [--const] [--zprefix] [--prefix=PREFIX] [--eprefix=EXPREFIX] [--static] [--64] [--libdir=LIBDIR] [--sharedlibdir=LIBDIR] [--includedir=INCLUDEDIR] [--archs="-arch i386 -arch x86_64"]

One way may be make sense: You can make a test with configure --64 and modify the makefile with adding -E to compiler flag and then run make test. After doing that, read the gzlib.o file and search fopen to see if there is *fopen or *fopen64. If you find it is *fopen64 that means you have compiled 64bit library.

thanks.

I tried this

    CC="cc -O4" \
        ./configure --64 --shared --prefix=$zlib_install_dir > configure.out

I added as you suggested the -E to the compiler flag.

CFLAGS=-fast -m64 -E -D_LARGEFILE64_SOURCE=1 the make failed

Ok, I tried the below command:

./configure --64 --shared

The make/test/install, all went successful. The shared libraries are all 64-bit.
