Re: [libtom] Problem compiling libtomcrypt with libtommath on a mac

[Steffen Jaeckel]

Hi,

I don't know if you solved it already but your 3. step should be like that:

sudo CFLAGS="-DUSE_LTM -DLTM_DESC -DLTC_EASY
-I/usr/local/Cellar/libtommath/1.0/include" make install
EXTRALIBS="/usr/local/Cellar/libtommath/1.0/lib/libtommath.a"

Cheers,
Steffen
