Mandriva上におけるOpenCVのコンパイル

OpenCVはマニアの間にたいへん人気があります。僕はマニアの人間じゃなくて、一時的に気になっている一人なのです。好きなMandrivaにOpenCVをコンパイルしようとすると、なかなか、./configure;make;make installの単純な手順でいきません。

コンパイルするために、configure.inに以下の箇所を修正する必要があります。

Image I/O ---------------------

libIlmImf:

1. ImfCRgbaFile.h → OpenEXR/ImfCRgbaFile.h

Video I/O ---------------------

ffmpeg:

1. libavcodec/avcodec.h　→ libavcodec/avcodec.h
2. libswscale/swscale.h　 → libswscale/swscale.h

Use unicap:

• --with-unicap

Wrappers for other languages =========================================

Python(interfaces/swig/python/Makefile.am):

1. _cv_la_LIBADD = $(top_builddir)/cv/src/libcv.la → _cv_la_LIBADD = $(top_builddir)/cv/src/libcv.la $(top_builddir)/cxcore/src/libcxcore.la
2. _ml_la_LIBADD = $(top_builddir)/ml/src/libml.la → _ml_la_LIBADD = $(top_builddir)/ml/src/libml.la $(top_builddir)/cxcore/src/libcxcore.la
3. _highgui_la_LIBADD = $(top_builddir)/otherlibs/highgui/libhighgui.la → _highgui_la_LIBADD = $(top_builddir)/otherlibs/highgui/libhighgui.la $(top_builddir)/cxcore/src/libcxcore.la

Octave:

• --with-octave

./configure --with-unicap=yes --with-octave=yesで実行すると、以下のようになります。

General configuration ================================================

Now run make ...

Compiling C Samples

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

cd /usr/local/share/opencv/samples/c

sh build_all.sh

swigでのpython

lib/python2.5/site-packagesの追加(追加の方法はPythonモジュール設定)
