Static Linking

[picasso]

Hi All,
I need some help about static linking of ImageMagick. As I get by reading some threads, building ImageMagick statically ( ./configure --disable-shared
) isn't enough, anybody can explain it, please?
Thanks

[picasso]

Why nobody helps?
Compile configuration command that I use:
./configure --disable-shared --disable-dependency-tracking --without-threads --enable-delegate-build LDFLAGS="-static" --prefix=/usr

and the result :
-------------------------------------------------------------------------------

I assume that what you want is for the ImageMagick utilities like convert and identify to be static executables. I don't know any way to do that, that isn't a hack.

After you run configure, try editing Makefile, and appending "-all-static" to the line that starts with "LDFLAGS =". That will cause libtool to link everything statically.

However, because configure didn't know you were going to link statically, it may not have correctly figured out which third-party libraries are available. You may have disable some libraries, and/or do some hacking, to make everything work.

[picasso]

Yes, that's what we need. I have to redistribute the convert tool in LFS ( Linux from Scratch ).
First of all I install staticly delegates ( tiff, jpeg, png, zlib, ... ) >>> ./configure --disable-share --enable-static
then I try to install image magick but I can't build a static convert and so on.

I get an error when trying LDFLAGS="-all-static"

Thank you very much jason! that was a great help, and finally I build a static "convert" tool!

Hi picasso, could you post your ./configure line after which you modified Makefile with -all-static?

[picasso]

my config command :

./configure --enable-shared=no --enable-static=yes --enable-delegate-build=yes --with-modules=no --prefix=/usr --without-threads

############

Now I want make a static convert with ghostscript !!! but it's really hard to do
after adding this --with-gslib=/usr/lib to ./configure ... , when run ( make LDFLAGS="-all-static" ) I get this error :

magick/.libs/libMagickCore.a(magick_libMagickCore_la-utility.o): In function `ExpandFilename':
magick/utility.c:648: warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

collect2: ld returned 1 exit status
make[1]: *** [utilities/animate] Error 1
make[1]: Leaving directory `/root/magick/ImageMagick-6.7.2-1'
make: *** [all] Error 2

this is from config result :

LIBS = -lMagickCore -ltiff -ljpeg -lgs -lpng12 -lbz2 -lz -lm
CXX = g++
CXXFLAGS = -g -O2

any idea?

[kaputzke]

Thank you for the config option, for me it fails at the same location for another lib:

/usr/bin/ld: cannot find -ltiff
collect2: ld returned 1 exit status
make[1]: *** [utilities/animate] Error 1
make[1]: Leaving directory `/home/tkrawuts/tmp/immck/ImageMagick-6.7.2-7'
make: *** [all] Error 2

The ouput of "make V=1":

make all-am

You can see the -all-static switch.
I am missing /usr/lib/libtiff.a for static linking, only .so are there. Just for a test I added --without-tiff to verify it fails at the next lib:

CCLD utilities/animate
/usr/bin/ld: cannot find -lfreetype
collect2: ld returned 1 exit status

So I assume I need some static libraries for tiff etc and you for gs. Or do you have libgs.a?
Which raises the question how to get/compile these libraries? The .a libs are noct part of -devel packages

Anyway I found a precompiled static 6.5.9 binary here which works fine for my application (its ok to create pdf):

[Jason S]

Of course, you need a static version (.a file) of any library that you're going to statically link to. If you can't get a static libtiff (etc.) from the same source as your shared libtiff, you'll have to build one yourself. That's usually not very hard, but you may need to be careful about how you configure it, and about possible version mismatches.

I don't really understand ImageMagick's relationship with GhostScript. Someone else will have to answer that. But if you do link ImageMagick and GhostScript, note that you might not be allowed to distribute the combined product. You'd be violating GhostScript's license, unless you can legitimately relicense everything to GPLv3.

before installing imagemagick you must compile delegates statically, try this for tiff, jpeg, zlib and so on :
./configure --enable-shared=no --enable-static=yes --prefix=/usr
then compile IM :
./configure --enable-shared=no --enable-static=yes --enable-delegate-build=yes --with-modules=no --without-threads --prefix=/usr
make LDFLAGS="-all-static"
make install

So I assume I need some static libraries for tiff etc and you for gs. Or do you have libgs.a?

yes, that's true! but I don't know how make libgs.a !

[kaputzke]

yes that worked,- so now I am stuck at the same point,- no libgs.a... I tried several versions and variants (ghostscript, gnu-ghostscript, espgs) but none of the buildchains spit out an libgs.a. A simple "ar -rv libgs.a objs/*o" in ghostscript build dir produced a non working library.

[picasso]

After a period of a couple months, I came-back to this project again! I'm going to find a solution for this problem
Any ideas?
Can somebody explain the relation between gs and imagemagick?

[fmw42]

Imagemagick uses Ghostscript as a delegate library to handle some vector format images, such as pdf.

If convert -list configure does not show gs in the line starting with DELEGATES, then IM has not found GS when IM was installed.
