Topic: Compile Mac i386 on a 64 machine

The following used to work in an old wolfSSL embedded SSL version (1.5.0)

./configure --without-zlib --enable-static --enable-shared=no CFLAGS="-arch i386 -mmacosx-version-min=10.4" LDFLAGS="-arch i386"

Now I get an error when building a lot of the binaries. Probably means that some outputs are picking up the platform override and some ignore it. Is there a new way I should be using to specify architecture?

Re: Compile Mac i386 on a 64 machine

Which version of wolfSSL are you using now?

Try:

$ ./configure --enable-static --disable-shared \
    C_EXTRA_FLAGS="-arch i386 -mmacosx-version-min=10.4" \
    LDFLAGS="-arch i386"

I tried this configure line on the latest pull from GitHub and it passed the make test.

CFLAGS was conflicting with something so we added C_EXTRA_FLAGS to cover the items you want to add. (I'm pretty sure that's why your configure is failing to build.) Note, we don't use ZLIB as a flag but we do have "--with-libz" as an option to add; it is disabled by default.

Re: Compile Mac i386 on a 64 machine

I got the latest version on the site 2.6.0
I still can't get it to work.
Below is what I am getting. Perhaps you are using an i386 machine to test? That would explain why I can't get it to work on a x86_64 machine (when I use -arch x86_64 all works fine).

Re: Compile Mac i386 on a 64 machine

You'll need to add --disable-fastmath as well since the mac gcc version no longer handles x86 assembly as well if you have to use i386 (see the note in the README under 2.6.0 ia32).  But that begs the question.  Why are you limiting to i386, is that even a possibility now?

Thanks,
-Todd

Re: Compile Mac i386 on a 64 machine

It works now. thanks!

I am trying to create a universal binary that will support old macs.
Once I have i386 and the x64 version I "concatinate" them using the lipo tool.
Now I have wolfSSL that can be linked to universal binaries.
