Using ImageMagick in Dev C++

Hi all,
I am using the Bloodshed Dev C++ program to write a C program, and I am having problems getting my program to compile because the compiler says that there are a HUGE amount of syntax errors contained within the ImageMagick header files. Relevant code included below
Code: Select all
#include <stdio.h>
#include <string.h>
#include <wand/MagickWand.h>
The amount of errors is crazy, far too many to try to correct manually.
Is there something I've done wrong or should I abandon my line of thought.
My program is trying to take user input then turn the text string into a DIB image but I can't compile past the #includes.
I have not changed any compiler options.
Please help.

Can you show us the first 20 or so error messages? There might be a clue there.

Ok, now the syntax of the header files are all right.
I am trying to run an example program manipulating text effects, but I have run into some more problems
The program I am trying to run is here
http://members.shaw.ca/el.supremo/Magic ... ffects.htm
The compiler is saying that every function I call to do with MagicWand is undefined.
Code: Select all
[Linker error] undefined reference to `NewMagickWand'
[Linker error] undefined reference to `MagickReadImage'
[Linker error] undefined reference to `MagickGetImageWidth'
[Linker error] undefined reference to `MagickGetImageHeight'
etc
I have read all the stuff on the forums and found it to be most unhelpful.
I am also not sure where to put the
Code: Select all
$magick> cc `MagickWand-config --cflags --cppflags` -o wand wand.c \
`MagickWand-config --ldflags --libs`
into Dev C++ and how to put it in.
Every time I try to either add it to the linker command line or 'add the following commands when calling compiler' section I get errors say that --cflags --cppflags --ldflags & --libs are unrecognised commands.

I've never used DEV C++ so I can't help you with it. Sorry.

I don't think its a problem with Dev C++. It looks like the compiler isn't finding any references for any of the Magick Wand Functions. ie NewMagickWand, MagickReadImage etc
Has anyone else had the same problem?

you have to reference the MagickWand library.
luckly for us it come in the ImageMagick windows binaries package among the headers.
make sure you follow this 2 steps and you will be OK with Dev-Cpp:
1.- in the proyect options/parameters: add the CORE_RL_wand_.lib file to the additional command line of the linker.
you have to use the full path (or add a default library search path)
2.- in the proyect options/directory: add the path where the ImageMagick headers are:
hope this can fix the problem

Hi all, hi xt5,
I also want to use Dev C++ and followed your 2 steps. Compiling my code then works fine, but I still get many linking errors e.g. [Linker error] undefined reference to `MagickReadImage' . See this two pictures of my configuration:
http://www.imgbox.de/show/img/ZRoJDSKbbH.png/
http://www.imgbox.de/show/img/sOOKMbEDen.png/
My Code is the code of the example "wand.c" from
http://www.imagemagick.org/script/magick-wand.php.
Can anybody please help me?
Thanks and Cheers
Marcel

MagickReadImage() is a method found in the MagickWand library. Verify you have included the MagickWand library in your link command line.

I have included MagickWand library by adding it to the linker parameters in project options.
I clicked on "Add Library or Object" and selected "CORE_RL_magick_.lib" and "CORE_RL_wand_.lib" from the lib directory of ImageMagick.
Here's the generated makefile
Code: Select all
# Makefile created by Dev-C++ 4.9.9.2
CPP = g++.exe
CC = gcc.exe
WINDRES = windres.exe
RES =
OBJ = test.o $(RES)
LINKOBJ = test.o $(RES)
LIBS = -L"C:/Dev-Cpp/lib" ../lib/CORE_RL_magick_.lib ../lib/CORE_RL_wand_.lib
INCS = -I"C:/Dev-Cpp/include" -I"C:/Programme/ImageMagick-6.6.7-Q16/include"
CXXINCS = -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include" -I"C:/Programme/ImageMagick-6.6.7-Q16/include"
BIN = Test.exe
CXXFLAGS = $(CXXINCS) -DBUILDING_DLL=1
CFLAGS = $(INCS) -DBUILDING_DLL=1
RM = rm -f
.PHONY: all all-before all-after clean clean-custom
all: all-before Test.exe all-after
clean: clean-custom
${RM} $(OBJ) $(BIN)
$(BIN): $(OBJ)
$(CC) $(LINKOBJ) -o "Test.exe" $(LIBS)
test.o: test.c
$(CC) -c test.c -o test.o $(CFLAGS)
What I am doing wrong? How to integrate the MagickWand library correctly?
Thanks

After reinstalling ImageMagick everything works fine
Thanks for your support
