Subject: Re: Release Build dependency on debug rt in vs7.1
Date: Sat, 08 Aug 2009 01:38:00 -0000	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

The pre-built pthreadVC2.dll is built using nmake and the Makefile 
provided (the actual commandline would have been "nmake clean 
VC-inlined"). I'm guessing the project file isn't inlining, which could 
account for the larger size for the pre-built dll.

For comparison with the project build, if you build with "nmake" as 
above you should find that the compile options are:-

/O2 /Ob2 /W3 /MD /nologo /I. /D_WIN32_WINNT=0x400 /DHAVE_CONFIG_H /DPTW32_BUILD_INLINED

Although there is a project file included in the sources it was 
contributed and is not otherwise maintained. I use the commandline tools 
for all building and testing of the dll because it makes the release 
process more consistent across the different build environments.
