Openmvg: [MacOS/MSVC] Error with new python scripts

[Meekohi]

Error when trying to run tutorial.py (or SfM_SequentialPipeline.py) on OSX. Python 2.7.9.

meekohi ~/openMVG_Build/software/SfM$ python tutorial_demo.py

('      output_dir : ', '/Users/meekohi/openMVG_Build/software/SfM/tutorial_out')

I think it's just because applications are not build in the same directory on Linux/Mac...
Can you check if OPENMVG_SFM_BIN is pointing to a valid directory and if there is some application inside it?

[Meekohi]

Looks empty.

meekohi ~/openMVG_Build$ echo $OPENMVG_SFM_BIN

meekohi ~/openMVG_Build$ 

[pmoulon]

Looks like I must export on MAC and Windows platform
IF(MSVC OR APPLE)
SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR ${CMAKE_CURRENT_BINARY_DIR}+${CMAKE_BUILD_TYPE})
ELSE()
SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR ${CMAKE_CURRENT_BINARY_DIR})
ENDIF()
for this line

[Meekohi]

IF(MSVC OR APPLE)
  SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_BUILD_TYPE})
ELSE()
  SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR ${CMAKE_CURRENT_BINARY_DIR})
ENDIF()

Seems to have done the trick :)

[pmoulon]

Windows seems prefer

IF(MSVC OR APPLE)
  SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_BUILD_TYPE}")
ELSE()
  SET(OPENMVG_SOFTWARE_SFM_BUILD_DIR ${CMAKE_CURRENT_BINARY_DIR})
ENDIF()

i believe i'm still having the same issue...

i'm on OSX 10.11.6 (El Captain). Python 2.7.14.

if i run:
python software/OpenMVG/openMVG_Build/software/SfM/tutorial_demo.py

i get:

Cloning into 'ImageDataset_SceauxCastle'...

@jango-fx Since depending of how you build OpenMVG on mac you can have a different output binary dir (XCode build or command line build with clang)
So, according this I did not find a generic way to put the OPENMVG_SFM_BIN = to the good value.
Here a fix you can do by hand:

• Please go on the top of the script and remove the last directory in the OPENMVG_SFM_BIN =. It should do the trick.

hah, trying to set the right folder, i realised my build was somehow incomplete. built it again, (this time with xcode?) now it runs smoothly!

thanks, though! super quick reply :D
