Re: compiler error with vs 2008

[Immanuel Dold <ihd2008@live.de>]

Hi Ross.

Thanks for the help. As I already told you I am not familiar with
setting up compiler flags. I tried setting /DNO_STRICT into the right
line. I copied it behind line 28 in the makefile so it now looks like
this: "CPPFLAGS = /I. /DHAVE_PTW32_CONFIG_H /DNO_STRICT" In the event
that this is indeed the correct line, the result is poor because I still
get the same errors as described below. Did I choose the wrong line?
Since the errors occur in "ptw32_MCS_lock.c" does my problem have to do
something with the "/DHAVE_PTW32_CONFIG_H" flag?

You already sad that the VCE version is not recommended so I tried using
VC for my project(s). Both of them build but the last one crashed with
an exception R6034. It seems some of the libraries static or dynamic
linked to my project use different versions of the C runtime library.
Because this problem is way out of my league I would prefer to stay with
VCE.

Given that I can not resolve my problem but have already got two of my
needed dlls, is there anybody who might give me the last .lib and .dll
files (VCE) working for windows?

I still have one question left. There are two options.
1. Build pthread with a x86 compiler and link it to a x86 program to run
it on a x64 windows.
2. Build pthread with a x64 compiler and link it to a (probably) x64
program to run it on a x64 windows.
Which of these two options is the right one? I am asking because I used
option one till now. Probably I wont be able to build my x86 programs as
64-Bit programs so if I have to use option two my whole project will
most likely fail.

Thank you again for the help. Best regards
Immanuel
