Hello everybody.
I am new to this project but I need help. I am a German student and I am
currently working with PTAM and libcvd. The program I am building works
fine under windows 7 32-bit. The problem is that my tutor for my thesis
works with windows 7 64-bit. You are probably guessing right that on
that machine the program only hangs. I get a 100% processor load but the
program not even gets to the main() function. Until now I used pthread
2.8.0 and after some research on the net I found out that I have to use
more recent code. Since there is no release I tried to build my own
libraries.
You do need to use the latest cvs version for 64 bit builds.
This is why I looked up for wincvs and checked out the newest code from
the server. I looked into the README file for instructions on how to
build all the .lib and .dll files. Now there is my problem. Using nmake
from Visual Studio 2008 Pro with the parameters "clean VC" and "clean
VSE" works just fine. But libcvd and PTAM rely both on the VCE version
and so I tried "nmake clean VCE" and there I got stuck. The compiler
throws errors (C2264) in "ptw32-MCS_lock.c" in lines 108, 127, 136, 197
and 215 saying that the it can not cast "volatile size_t *" into
"volatile LONG *".
You may find that using the VC build works with your application. The
VCE version has problems anyway and is not really recommended.
This problem has been reported to me by Daniel Richard G. who has also
provided a substantial patch that also includes a large number of
other changes not necessarily related to this issue. Unfortunately I
just don't have the time now or the [64 bit MSVS] tools to properly
incorporate and test complex patch sets or coordinate those who do,
considering that this project aims to work with several compilers
(e.g. MS and GNU) and their various versions and supported architectures.
But I do want to note here that the current code in cvs has been built
and well tested on several 64 bit systems and compilers, but
presumably not using this specific MSVC++ compiler version.
I don't know if this link helps at all with the cast error, i.e.
adding the /DNO_STRICT compiler option to the compiler flags in the
nmake Makefile:
