[SIP-devel] Some minor path problems with ImageMagick

[Vasileios Z. <vzo...@bc...>]

Hello again Ricardo. Sorry about the Italian mixup but your last name 
kinda confused me. The .br in your email address should have been a clue.

Anyways back to work.
I have been looking around the various C source files just to see how 
complicated interfacing with Scilab is. Fortunately it doesnt look 
complicated enough (well from a first glance), so I should be able to 
catch on quite quickly.
Now...another little issue. Because I recently upgraded from SuSE to 
RedHat 8 I have been having the bug problems that you mention with 
Imagemagick (yes its even buggy in RH 8). So I downloaded the source and 
build from that.
I did ./configure --enable-shared=yes --with-perl=no (somehow it doesnt 
like it with Perl when it "makes" anyway). And I installed everything fine.
I exec the sip builder file and everything builds fine.
However in the loader i get the following in Scilab:



-->;exec("/home/vzograf/sip-dev/loader.sce");
SIP - Scilab Image Processing Toolbox loaded
Enter "sipdemo()" for a demonstration
 
Loading shared executable ./cybervis/libcybervis.so
./cybervis/libcybervis.so: undefined symbol: SetImagePixels
link(libsip_path+'/cybervis/libcybervis.so');
                                             !--error   236
link: the shared archive was not loaded
at line       4 of exec file called by :    
   exec loader.sce;
line    44 of exec file called by :    
;exec("/home/vzograf/sip-dev/loader.sce");


 From what I can understand it cannot find the Imagemagick 
SetImagePixels function from the image.h header that exists in the 
magick directory (for me /usr/local/include/magick/). Have you got any 
idea how to fix this? I am going to look at it overnight but if you know 
and tell me you will save lots of work. Thank you

This is a link problem. Check if you did the right bugfix in the
/usr/lib/scilab-2.6/config/Makeso.incl

For sip-dev, change the line:
	LDFLAGS =
	to
	LDFLAGS = $(EXTRA_LDFLAGS)

Note that this is different from the sip stable release, in which
case you should use OTHERLIBS instead of EXTRA_LDFLAGS.

Go to the sip-dev source directory and type "make distclean" before
running builder.sce again.

please let me know if it works now.

PS: this building process is cumbersome. I'm working on direct
autoconf/automake/libtool support in SIP to make a solid
build/installation process.

Ricardo.

Hey Ricardo,

ok it now works.

For a second there it gave me a new error that it couldnt find the file 
libMagick-5.5.2.so.0
so I also had to change the /etc/ld.so.conf file to include the 
/usr/local/lib directory and run ldconfig

Ok...thanks for your help
Vasileios
