building TrueCrypt from source

As there are no existing TrueCrypt for GNU Linux/Sparc, we had to do this ourselves. However, the buildprocess is not pretty and for some reason one just *has* to build all that wxWidget stuff, although I don't intend to manage crypto devices with my mouse, sigh. Oh, and there were quite a few build errors but thanks to Kano we finally succeeded. Here it goes, the whole shebang for TrueCrypt-6.1a:

# apt-get install libfuse-dev pkg-config
# mkdir /usr/local/include/pkcs11-v2-20
# cd /usr/local/include/pkcs11-v2-20
# for i in pkcs11.h pkcs11f.h pkcs11t.h; do \
   wget$i; done
# for i in `pwd`/*h; do (ln -s $i /usr/include); done 
# cd /usr/local/src
# wget
# tar -xjf wxWidgets-2.8.9.tar.bz2
# cd ~/dev/truecrypt-6.1-source
# make NOGUI=1 WX_ROOT=/usr/local/src/wxWidgets-2.8.9 wxbuild
[....hours later on this box....]
# file Main/truecrypt 
Main/truecrypt: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically
linked (uses shared libs), stripped
Note: it's really important to get v2.20 of the PKCS11 header files, the current version did not work. Also, Debian/Etch comes with libwxgtk2.[46]-dev - the build failed and I really had to get the 2.8 version. Update: Although the build worked, truecrypt doesn't. Rebuilding with DEBUG=1 DEBUGGER=1 NOSTRIP=1 made gdb(1) spit out all the gory details:

Hm, but even running truecrypt --test was showing the same behaviour: TestXtsAES just fails to work. However, when trying to create the volume with another cipher, it still crashes at TestXtsAES, because VolumeCreator::CreateVolume always calls EncryptionTest::TestAll before actually creating the volume. Commenting out this call in VolumeCreator.cpp:179, recompiling and trying to create the volume with the Twofish cipher gives:
Program received signal SIGBUS, Bus error.

Wow, now it fails at the hashing algorithm. When using SHA-512 instead of ripemd-160, it still crashes:

...and that's it. Still SIGBUS for truecrypt, and -ENOSKILL for me, for not knowing C++ at all. Looks like truecrypt just wasn't meant to be run on big endian platforms. Damn.
