Building on Windows fails: Determining if the _POSIX_TIMERS exist failed

[mkaze]

I wanted to build the libnado according to the instructions provided here. Unfortunately it failed at step 9. Here is the cmake output:

Boost version: 1.59.0
CMake Error at CMakeLists.txt:25 (message):
  Cannot grep version number: The system cannot find the file specified


Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE)

And here is CMakeError.log contents:

I am using Windows 8.1 pro(x64) and VS2013. I think the problem is caused by 'unistd.h' which is a header file in Unix, however I'm not sure if this is a bug or a problem with my configurations.

Note: CMake couldn't find the boost path (which resulted in an error like : "Boost_INCLUDE_DIR not found"), so I added these lines at the beginning of 'CMakeLists.txt':

SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/ICP/boost_1_59_0")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "C:/ICP/boost_1_59_0/build")

Hi mkase,

So I see three problems in your CMake outputs:

1. This error is reported from the line 25, but in the latest version of libnabo, it should be on line 16. Do you have the latest version of libnabo? Could you check if that line match your local version?
   CMake Error at CMakeLists.txt:25 (message): Cannot grep version number: The system cannot find the file specified

2. Did you add manually a PATH variable named BOOST_ROOT through CMake Gui? This should avoid you to change the CMakeFile.txt manually. See step 7.

   Note: CMake couldn't find the boost path (which resulted in an error like : "Boost_INCLUDE_DIR not found"), so I added these lines at the beginning of 'CMakeLists.txt':

3. The last one is interesting and it's related to cmake not being able to build CheckSymbolExists.c. I searched for that a bit and it's seems to be often related to another problem (like boost wrongly linked).

Thanks for your reply François Pomerleau.

Regarding the problems you mentioned:

1. The difference in line numbers is due to the fact that I have added the lines for finding boost path at the beginning of 'CMakeLists.txt'.
2. Yes. I followed the instructions step by step and added the BOOST_ROOT variable but even by doing so, it resulted in the the error that I mentioned. I read about that solution here.
3. I'm not sure about that either. I followed the steps in instruction carefully and did them from beginning more than five times but I couldn't make it.

Maybe building the boost library again would solve the problem. I would try that and let you know if any changes happen.

[pomerlef]

Could you report all the versions you have on your system based on that table and other you think would be useful. That might help others.

I'm seeing a lot of similar questions on stackoverflow without any answers. It might be something trigger by the latest version of CMake or different version of .NET framework, etc. I'm also seeing "C:/Program Files (x86)/MSBuild/12.0/bin/MSBuild.exe, should it be (x64)? But all that are only speculations, I'm not expert enough on Windows system to help you directly.

[drhalftone]

I'm seeing this exact issue on Mac OS X. I got past it by commenting out the tests subdirectory, but it would to see this resolved.

[pomerlef]

I just realized that this problem is related to libnabo and not libpointmatcher. The issue was transferred to them here so I'll close that one on our side.

[DoobieDuh]

@mkaze I have the same problem but I still have not found the solution to it.

CMake Error at tests/CMakeLists.txt:95 (message):
Compiling a test executable failed.

I just want to know how did you solve this problem at the end? Thank you so much!

For anyone stock with the Build of Libnabo on windows with the "Cannot grep version number:" error, you can contour this error by
removing the following lines in the CMakeLists.txt file of the Libnabo:
**
if (NOT GREP_VERSION_RESULT EQUAL 0)
message(SEND_ERROR "Cannot grep version number: ${GREP_VERSION_RESULT}")
endif (NOT GREP_VERSION_RESULT EQUAL 0)
string(REGEX REPLACE "."(.)".*" "\1" PROJECT_VERSION "${PROJECT_VERSION}" )
**

The reason is that GREP is not a recognized command in windows.
