devkitPro is a set of tool chains for compiling to gaming platforms. This includes the Nintendo Switch, 3DS, Wii, and Gamecube. If you need cryptographic or SSL/TLS capabilities in your games then wolfSSL has support for compiling with devkitPro. wolfSSL is a very lightweight and fast SSL/TLS library that will fit perfectly in a constrained game console environment.
This blog will showcase how to compile the wolfSSL
testwolfcrypt program for Wii and run it in the Dolphin Emulator. It assumes that the devkitPro was installed in
Compile wolfSSL using the devkitPPC tool chain:
./configure CFLAGS='-DDOLPHIN_EMULATOR -DDEVKITPRO -DGEKKO -DNO_WRITEV -I/opt/devkitpro/libogc/include -mrvl -mcpu=750 -mno-eabi -MMD -MP' LDFLAGS='-L/opt/devkitpro/libogc/lib/wii -lwiiuse -lbte -logc -lm' CC=/opt/devkitpro/devkitPPC/bin/powerpc-eabi-gcc RANLIB=/opt/devkitpro/devkitPPC/bin/powerpc-eabi-ranlib --host=ppc --enable-cryptonly --disable-shared --enable-static --disable-filesystem
Then convert the binary to a
/opt/devkitpro/tools/bin/elf2dol wolfcrypt/test/testwolfcrypt ../testwolfcrypt.dol
The above command places the resulting binary in the directory that contains the wolfssl directory. Navigate to this directory in the Dolphin Emulator and run it:
All tests should pass and you may close the window. If you have additional questions about support for devkitPro targets, please write to us at email@example.com.
