I'm looking at some OpenEXR image format library detection code we've added to our configure.in. This code was adapted from code our configure.in uses to detect the TIFF library, but isn't working with OpenEXR. Nobody working on our project is very familiar with autoconf. It could be something very simple that's wrong. AC_MSG_CHECKING(for openexr support) AC_CHECK_FILE(/usr/include/OpenEXR/half.h,,AC_MSG_ERROR(*** openexr header file not found ***)) AC_CHECK_FILE(/usr/lib/libIlmImf.a,,AC_MSG_ERROR(*** openexr dev file not found ***)) AC_CHECK_LIB(IlmImf,ImfApplyLut,,AC_MSG_ERROR(*** openexr dev lib not found ***),) AC_CHECK_HEADER(OpenEXR/half.h, OPENEXR_INCLUDES="-I$prefix/include/OpenEXR"; OPENEXR_LIBS='-lIlmImf -lImath -lIex -lHalf -lz', AC_MSG_ERROR(*** openexr dev header half.h not found ***)) I added the AC_CHECK_FILE calls only for the purpose of testing. They pass. The AC_CHECK_LIB and AC_CHECK_HEADER calls fail. (Each will fail, whichever is first). The only significant thing that seems different about OpenEXR and TIFF library is that OpenEXR is a C++ library, not C. What's wrong? Is this even the right approach?
