未找到 Windows7 pthread.h

Question

I am trying to compile libaws (http://sourceforge.net/projects/libaws/) library in Windows using cmake. I have included openssl, libxml, libcurl and I am using this command line.

C:\libaws>cmake -G "Visual Studio 10" -DCURL_LIBRARY="C:\tools\curl-7.28.1\lib" -DCURL_INCLUDE_DIR="C:\tools\curl-7.28.1\include" -DLIBXML2_LIBRARIES="C:\tools\libxml22.7.8.win32\lib" -DLIBXML2_INCLUDE_DIR="C:\tools\libxml2-2.7.8.win32\include" -DPTHREAD_INCLUDE_DIR="C:\tools\pthread\include"  ..\tools\libaws-0.9.2
--    

It throws the following error:

-- Check for working C compiler using: Visual Studio 10
-- Check for working C compiler using: Visual Studio 10 -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler using: Visual Studio 10

CMake Error at CMakeLists.txt:78 (MESSAGE): Could not find pthread development headers

I have included ptherad.h, semaphore.h etc. in C:\tools\pthread\include, and provided that as a command line flag: -DPTHREAD_INCLUDE_DIR="C:\tools\pthread\include". In my CMakeLists.txt, I added

INCLUDE_DIRECTORIES(${PTHREAD_INCLUDE_DIR})

Any ideas?

Answer 1

Visual Studio doesn't come with a "pthread" implementation. I guess you'll need to use another compiler, like MinGW.

@jens-a-koch is right: my answer should not be accepted! Please "unaccept" so I can remove it.

I belive that your CMake find module might not be using the PTHREAD_INCLUDE_DIR define (similarly to what@ drescherjm said).

Answer 2

I had the same error and the solution in short was to install Git for windows !

-- Looking for pthread.h
-- Looking for pthread.h - not found
-- Found Threads: TRUE

and in CMakeError

checkIncludeFile.c(1,1): fatal  error C1083: Cannot open include file: 'pthread.h': No such file or directory
CheckIncludeFile.c(1,1): fatal  error C1083: #include <pthread.h>

I already have github app and I used it to clone my project, but for some reason CMake needed Git for windows , so if anyone had this issue this is what worked for me after hours of search
