Hello. I am getting started with Magic++ and am having a problem getting a basic program to run. Here is the code.

#include <iostream>
#include <Magick++.h>

using namespace std;
using namespace Magick;

int main()
{
    Image hello_image;
    hello_image.read("/media/[myUserName]/Data/test.bmp");
    hello_image.display();
    return 0;
}

I am compiling with Code::Blocks GCC compiler running under Linux Mint, and have successfully gotten the program to compile; however, the program crashes when run giving the following error.

Code: Select all

ImageMagicTest: magick/semaphore.c:531: LockSemaphoreInfo: Assertion `semaphore_info != (SemaphoreInfo *) ((void *)0)' failed.
Aborted

Process returned 134 (0x86)   execution time : 0.006 s
Press ENTER to continue.

I haven't been able to figure out what is going on since googling Magic++ and the error will only give a handful of results, however, I have pinned the issue down to the line where I try to read in the image. I was confident with the code since it matches the examples given, but obviously something isn't working. Can anyone help me with this?

Thanks.

I supposed you've built the IM system with the same compiler etc?

I think LockSemaphoreInfo is used only for multi-threading, so you might rebuild without multithreading.

I should also ask: what version of IM?

I downloaded the API using apt-get and don't know the version number, but since this seems to be a problem resident to the build, I will try building my own without multi-threading.

Okay, I built from source this time, with the option --without-multithread specified when configuring. (please correct me if did this at the wrong time, I am not used to building from source that often) Anyway, I am using GraphicsMagick-1.3.25/Magick++ now. After making and installing, I changed my include statement to

Code: Select all

#include </home/[myUsername]/Programming/GraphicsMagick-1.3.25/Magick++/lib/Magick++.h>

However, when I compile, I get the same error when trying to run the program.

This is an Imagemagick forum. Imagemagick is not the same as GraphicsMagick. You should consult the GraphicsMagick forum when installing GraphicsMagick.
