LuxRender v0.6 Release Candidate 5 - Windows/Linux/MacOSX

[PhilBo]

Okay...I'm a noob. I'm trying to build RC5 on Linux. I tried to install Boost 1.39 and I thought that I did it successfully. I did a cmake lux which listed

Code: Select all

Boost version: 1.39.0
-- Found the following Boost libraries:
-- Boost library directory: /usr/lib
-- Boost include directory: /usr/include


So...it seemed that things were correct. I then issued the make command and it looked good until right at the end when it popped out the following...

Code: Select all

[ 96%] Building CXX object CMakeFiles/lux.dir/volumes/volumegrid.o
Linking CXX static library liblux.a
[ 96%] Built target lux

collect2: ld returned 1 exit status
make[2]: *** [luxconsole] Error 1
make[1]: *** [CMakeFiles/luxconsole.dir/all] Error 2
make: *** [all] Error 2


Any idea on how to correct?

Your boost libs are probably named something slightly different - see in /usr/lib.

Anyway, I uploaded optimized ia32 and x64 linux builds this afternoon - they will be linked to as soon as someone with access to the filesystem drops by and updates the parent post.

Hi everyone!

I had the same problems as PhilBo.

My OS is Bluewhite64 linux 12.2 (64-bit version of Slackware linux 12.2).
I had boost 1.38 installed.
Luxrender 0.6RC5 compiled and worked (almost) well with this version of boost.
I know that boost 1.39 is recommended to built Luxrender properly, but it worked with boost 1.38 and it was OK for me.
Once I found a situation that Luxrender RC5 crashed with a scene which was rendered fine in RC4, I decided to upgrade to boost 1.39 (I will write separate message about that scene).
So, I compiled boost 1.39 from source (it is usual for Slackware), then I began to compile Luxrender RC5 and it happened that it compiled but refused to link and gave me the following error:

Code: Select all

Linking CXX executable luxconsole
/usr/lib/gcc/x86_64-pc-linux/4.2.4/../../../../x86_64-pc-linux/bin/ld: cannot find -lboost_program_options-mt
collect2: ld returned 1 exit status
make[2]: *** [luxconsole] Error 1
make[1]: *** [CMakeFiles/luxconsole.dir/all] Error 2
make: *** [all] Error 2

After some time I found that the file
[location of the folder in which you are compiling Lux ]/CMakeFiles/luxconsole.dir/link.txt
contains following information about boost libraries:
boost_thread-mt
boost_program_options-mt
boost_filesystem-mt
boost_serialization-mt
boost_iostreams-mt
boost_regex-mt
but my /usr/lib folder contains libraries
libboost_thread.so (without "-mt" suffix) etc.
So I changed boost_thread-mt to boost_thread and so on in this file, and by analogy did the same procedure in the file
[location of the folder in which you are compiling Lux ]/CMakeFiles/luxrender.dir/link.txt
And after that linking procedure was successful.

I really don't know why boost 1.39 compiled in such a way in difference with 1.38.
So I think it may be useful to anticipate this situation in the process of automatic generation of configuration files.

And this is why I said I would wait LOL...

Looking forward to it guys.

Hi once again.

I have the following problem with RC5.
I decided to test it on a scene which was rendered with a positive haltspp. I also saved .flm file of that scene previous time and forgot to delete it. And Luxrender RC5 crashed when it finished parsing that scene and began to read data from .flm
I checked that when RC5 opens scene with .flm data the render of which is not finished (haltspp is zero or spp is less than haltspp), it does not crash.

I modeled this situation once again but launched Luxrender from console, which gave me the error message:

Code: Select all

luxrender: pthread_mutex_lock.c:87: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed.

By the way, when I render a scene with a positive haltspp and .flm file does not exist at the beginning or contains data of non finished render (spp is less than haltspp), then at the end Luxrender RC5 gives the error:

Code: Select all

2009-Aug-10 01:20:28 Severe error: (14) Assertion '!pthread_mutex_lock(&m)' failed in function 'void boost::mutex::lock()' (file:/usr/include/boost/thread/pthread/mutex.hpp line:50)
2009-Aug-10 01:20:28 Severe error: (14) Assertion '!pthread_mutex_unlock(&m)' failed in function 'void boost::mutex::unlock()' (file:/usr/include/boost/thread/pthread/mutex.hpp line:55)

and Luxconsole rises the error:

Code: Select all

[Lux 2009-Aug-10 01:31:42 SEVERE ERROR : 14] Assertion '!pthread_mutex_lock(&m)' failed in function 'void boost::mutex::lock()' (file:/usr/include/boost/thread/pthread/mutex.hpp line:50)

You should compile your boost libs with -mt (multithreading support) - I don't know for sure this is related to your crash but you should do it anyway

When will the 32bit windows version be avaiable ? I didn't manage to compile one by my own - but cant wait to try it

best regards

Radiance told me he'll try to do them this evening.
