primax: Thread: primax_scan-0.2 >>>> please help

Hi,

i`ve tried to compile  primax_scan-0.2 
on my Linux-box, but.....:

debian:/tmp/primax_scan-0.2# make
gcc -O -c -g -I/tmp/tiff-v3.4beta037/libtiff/ primax_scan.c
gcc -O -c -g -I/tmp/tiff-v3.4beta037/libtiff/ probe_lp.c
gcc -O -c -g -I/tmp/tiff-v3.4beta037/libtiff/ data.c
gcc -O -c -g -I/tmp/tiff-v3.4beta037/libtiff/ old_stuff.c
cc -ltiff -lm -O -g primax_scan.o probe_lp.o data.o old_stuff.o -o primax_scan
ld: cannot open -ltiff: No such file or directory
make: *** [primax_scan] Error 1
debian:/tmp/primax_scan-0.2# 

What the hell is ltiff  ????		:-O 

I use debian slink and Kernel 2.2.13 on an Pentium 166
with a Primax Colorado Direct Scanner... and (sorry )a bad english.


TIA for helping me. :-)

Well, -ltiff means that the compiler should look for a file called
libtiff.so (or libtiff.a).  It's usually found in one of /usr/lib,
/usr/local/lib, or sometimes /usr/X11R6/lib. Try looking for a debian
package called libtiff, and install it with dpkg.

Sorry I can't help more than that, I'm a FreeBSD user.  :-)

How about this driver under FreeBSD? It isn't working, is it?

Also, ich habe nun libtiff3_3.4beta037 Installiert und dazu noch primax_scan
0.93, aber...
der Compiler sucht immer noch ltiff, sprich libtiff.a oder libtiff.so

ich glaube auf meinem system befindet sich keine libtiff.a  oder  *.so

es gibt aber eine libtiff.so .ist die das?

die Makefil von primax_scan habe ich zu TIFF_INCLUDE = /usr/lib ergänzt.

es klappt nur nicht und ich verstehe die welt nicht mehr.


ich bin weiterhin
sehr dankbar für jede hilfe

Hi Oliver,
	Please remember that this list is an international one.
At least putting your message in both your native language and 
in english is always a good idea.
Anyway check out the following page to find your appropriate
"tiff" package.

Hi,
thanx a lot for helping me.  

Now, I` ve installed libtiff-devel and zlib-devel

but my output was:

make: *** [primax_scan] Error 1     


What's the matter, now ?  8-O

That is a common problem (I'm not sure how it's happened), but all the
libraries (the flags beginning with -l) need to be specified at the end
of the command line.  If you edit the Makefile and change the line:

	cc -ltiff -ljpeg -lm -lz -O3 $(PRIMAX_SCAN_OBJS) -o $@

to read:

	cc -O3 $(PRIMAX_SCAN_OBJS) -o $@ -ltiff -ljpeg -lm -lz 

Then things will work better.  While you're editing the Makefile, be
careful that the initial bit of space on that line stays a tab and
doesn't get converted to 8 spaces, or make will barf.

Recently, I have discussed this issue with someone else.
In fact, it seems to depend on the compiler specs and/or ld version.

At least with gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 
release) with GNU ld version 2.9.1 it doesn't matter where 
you place the library flags. I don't know why.
