libtheora Dependencies

Required

libogg-1.3.5

Recommended

Optional

sdl12-compat-1.2.64 and libpng-1.6.40 (both to build the example players), Doxygen-1.9.7, texlive-20230313 (or install-tl-unx), BibTex, and Transfig (all four to build the API documentation), and Valgrind-3.21.0

Installation of libtheora

Install libtheora by running the following commands:

sed -i 's/png_\(sizeof\)/\1/g' examples/png2theora.c &&
./configure --prefix=/usr --disable-static &&
make

If you wish to run the tests, issue: make check.

Now, as the root user:

make install

If you wish to install the examples (so that you can hack on theora), install them as the root user:

cd examples/.libs &&
for E in *; do
  install -v -m755 $E /usr/bin/theora_${E}
done

Command Explanations

sed -i 's/png_\(sizeof\)/\1/g' examples/png2theora.c: This sed fixes build with libpng 1.6.

--disable-static: This switch prevents installation of static versions of the libraries.
