The ticket may have been closed a bit early. The problem seems to be
related on how the library is being detected. I have the following
installed:
openjpeg2 library (64 bit + headers)
openjpeg 1.5 (64 bit + headers)
openjpeg 1.5 (32 bit + headers provided by the 64 bit package)
The configuration should be able to detect that the openjpeg2 library (32
bit) is not available, even if the headers are available from the 64 bit
version (and then move to testing version 1.5). 64 bit packages are always
required by the 32 bit packages because of it is the 64 bit package that
contains the header files. They are installed under /usr/include.
By the way, I use the following (as does the PKGBUILD) before calling
"configure".
export PKG_CONFIG_PATH="/usr/lib32/pkgconfig"
