How do I build OpenSSL as 32-bit (i386) on Mac OS X?

Question

I downloaded OpenSSL sources, and did the config, make, sudo make install trilogy.

I then built my project, linking in libcryp

Answer 1

$ curl https://www.openssl.org/source/openssl-1.0.0a.tar.gz | tar xz
$ cd openssl-1.0.0a
$ export CFLAGS="-arch i386"
$ export LDFLAGS="-arch i386"
$ ./config
$ make
$ lipo -info libssl.a
input file libssl.a is not a fat file
Non-fat file: libssl.a is architecture: i386
$ lipo -info libcrypto.a
input file libcrypto.a is not a fat file
Non-fat file: libcrypto.a is architecture: i386

Answer 2

If anybody is looking for a solution to build dynamic libraries, this is how to do it:

tar -xvzf <openssl gz file>
./Configure darwin-i386-cc -shared 
make

For 64 bit, run

./Configure darwin64-x86_64-cc -shared
make
