Submitted:	13 Jan 2011 17:36	Modified:	30 Jul 2019 12:30
Reporter:	Santo Leto	Email Updates:
Status:	Won't fix	Impact on me:	None
Category:	MySQL Server: Compiling	Severity:	S3 (Non-critical)
Version:	5.5.9-rev.3238-bzr	OS:	Windows (Vista 32-bit)
Assigned to:		CPU Architecture:	Any
Tags:	cmake, CMAKE_HAVE_PTHREAD_H

Description:
CMAKE_HAVE_PTHREAD_H triggers a warning when using VS Express.

How to repeat:
* Test 1:

- open visual studio command prompt
- mkdir ofs-nmake-5.5.9-rev-3238-pthreadTest1-bis
- cd ofs-nmake-5.5.9-rev-3238-pthreadTest1-bis
- cmake -DBUILD_CONFIG=mysql_release -G "NMake Makefiles" ..\mysql-5.5

* Test 2 (if this is appropriate):

- download and unzip package "pthreads-w32-2-8-0"
- edit your "include" environment variable to include "C:\pthreads-w32-2-8-0\Pre-built.2\include"
- edit your "lib" environment variable to include "C:\pthreads-w32-2-8-0\Pre-built.2\lib"

continue like we did before:

- open visual studio command prompt (a new one)
- mkdir ofs-nmake-5.5.9-rev-3238-pthreadTest2
- cd ofs-nmake-5.5.9-rev-3238-pthreadTest2
- cmake -DBUILD_CONFIG=mysql_release -G "NMake Makefiles" ..\mysql-5.5

Output:

* Test 1:

You don't need to download any pthread package to compile MySQL Server on Windows. AFAIK it's not even supported since MySQL Server uses a very slim built in pthread emulation layer on Windows.

The build system should not detect pthread on Windows. Is that what your bug report is trying to point out?

Hi Magnus,

Thanks for your reply.
Yes, I was wondering why I see this warning and how to remove it

-- Looking for include files CMAKE_HAVE_PTHREAD_H - not found.  

If the build system should not detect pthread on Windows, then this bug is about avoiding that a (not necessary) warning is printed.

Thanks

Thank you for the bug report.
