Hi,
My issue is that I'm using Cycas 3.9 [1] on Linux, which interfaces with a
locally-compiled Povray 3.7-stable by putting out an argument set like:
+I/home/jonathan/.cycas3/tmp//cycas.pov +P +D0 +X100 -V +SP32 +EP4 +W1024 +H768
+FC +O/home/jonathan/CYCAS3//tryit.png +Q9 +R1 +AM2 +A0.3 -J
This falls foul of a known bug [2] related to mosaic pretrace. Rather than
intercept and process the argument set between Cycas and Povray, I thought it
might be easier to grab the current Master branch from github, and recompile
that, as it has Christoph's workaround for FS#313 in radiosity.cpp.
However, having executed prebuild.sh, I get an error with configure that I
didn't see with 3.7.0-stable.
[code]
$ ./configure COMPILED_BY="jonathan[at]blueyonder[dot]co[dot]uk"
--without-libmkl
......
checking whether to use the ZLIB library... yes
checking for library containing zlibVersion... no
configure: error: cannot find a suitable ZLIB library
$ dpkg -l | grep zlib
ii zlib1g:amd64 1:1.2.7.dfsg-13ubuntu2
amd64 compression library - runtime
ii zlib1g:i386 1:1.2.7.dfsg-13ubuntu2
i386 compression library - runtime
ii zlib1g-dev:amd64 1:1.2.7.dfsg-13ubuntu2
amd64 compression library - development
[/code]
So I seem to have zlib development library installed.
And indeed, config.log seems to indicate that it's a problem with a boost
library (maybe - I'm getting out of my depth...)
[code]
configure:7946: g++ -o conftest -pthread -pthread -I/usr/include -L/usr/lib
conftest.cpp -lz -lboost_thread-mt -pthread -lboost_system >&5
/usr/bin/ld: cannot find -lboost_system
collect2: error: ld returned 1 exit status
configure:7946: $? = 1
......
configure:7963: result: no
configure:8068: error: cannot find a suitable ZLIB library
[/code]
Comparing this with the relevant section of the successful config.log from
3.7.0-stable, I see there:
[code]
configure:7924: g++ -o conftest -pthread -pthread -I/usr/include -L/usr/lib
conftest.cpp -lz -lrt -lm -lboost_thread-mt -pthread >&5
configure:7924: $? = 0
configure:7941: result: -lz
configure:7948: checking zlib.h usability
configure:7948: g++ -c -pthread -pthread -I/usr/include conftest.cpp >&5
configure:7948: $? = 0
configure:7948: result: yes
configure:7948: checking zlib.h presence
configure:7948: g++ -E -pthread -I/usr/include conftest.cpp
configure:7948: $? = 0
configure:7948: result: yes
configure:7948: checking for zlib.h
configure:7948: result: yes
configure:7952: checking for libz version >= 1.2.1
configure:7974: g++ -o conftest -pthread -pthread -I/usr/include -L/usr/lib
conftest.cpp -lz -lrt -lm -lboost_thread-mt -pthread >&5
configure:7974: $? = 0
configure:7974: ./conftest
1.2.7
configure:7974: $? = 0
configure:8013: result: 1.2.7, ok
[/code]
So, I conclude that the master branch configure is looking for lboost_system,
without success, whereas 3.7.0-stable didn't look for it when testing for zlib.
I have 14 libboost-* packages installed, including libboost1.49-dev.
Any help would be gratefully accepted, otherwise it's back to a bash hack on
that command line!

Apparently we still haven't fully sorted out one of the breaking changes
between boost 1.49 and 1.50, which is that since 1.50 the boost_thread
library requires the boost_system library to be linked in.
In the 3.7.0-stable, this hadn't been addressed at all, making it
necessary for people using boost 1.50 or higher to explicitly add
boost_system to the list of libraries to be linked in.
In the current master branch, this has been changed, so that
boost_system is now linked in automatically; however, apparently this
now also happens with boost 1.49 and lower.
Sorry about this; I'll see what can be done to fix this problem. If
you're in a hurry, try explicitly installing the boost_system library
(you probably won't need the -dev package), or upgrade to boost 1.50 or
higher.

Okay, I think I've found the root cause. Can you please try with this
branch:
https://github.com/POV-Ray/povray/tree/hotfix/boost1.49-boost_system
Please let me know if this solves your problem.

That works, thank you. I've configured, had a successful 'make check' and then
installed using 'checkinstall -D make install'. Everything works just as it
should; the proof is at

Thanks again for all your efforts keeping POVRAY going; I really appreciate it.
