Source: opencv Version: 2.4.9.1+dfsg-1.1 User: [email protected] Usertags: sphinx1.3
opencv FTBFS with Sphinx 1.3 (which is available in experimental),
because cmake cannot detect Sphinx properly. This can be seen in
cmake output:
-- Documentation:
-- Build Documentation: NO
-- Sphinx: NO
-- PdfLaTeX compiler: /usr/bin/pdflatex
The relevant code in cmake/OpenCVDetectPython.cmake is:
find_host_program(SPHINX_BUILD sphinx-build)
if(SPHINX_BUILD)
execute_process(COMMAND "${SPHINX_BUILD}"
OUTPUT_QUIET
ERROR_VARIABLE SPHINX_OUTPUT
OUTPUT_STRIP_TRAILING_WHITESPACE)
if(SPHINX_OUTPUT MATCHES "Sphinx v([0-9][^ \n]*)")
set(SPHINX_VERSION "${CMAKE_MATCH_1}")
set(HAVE_SPHINX 1)
message(STATUS "Found Sphinx ${SPHINX_VERSION}: ${SPHINX_BUILD}")
endif()
endif()
Here it calls 'sphinx-build' and expects the output to be
"Sphinx v([0-9][^ \n]*)".
However with Sphinx 1.3, 'sphinx-build' prints:
$ sphinx-build
Error: Insufficient arguments.
You need to pass --version and adjust the regex a bit:
$ sphinx-build --version
Sphinx (sphinx-build) 1.3.1
