Hello to all,

How to disable assert statements in ImagMagick?

I am using RHL 5.4 and gott the latest source code, I know there is --disable-assert opiton in ./configure, but
I have tried it several times, it does work for me. Later I tried to change the
resulted makefile directly, so that the CXXFlAG has a -NDEBUG option, but
the resulted build library still has assert statement. I am sure the *.a file has
been updated since I have check the time it was created.

I have two ways to check if the library file has assert statement,
first I use nm -a xxx.a | fgrep assert
second I get assert error when running my program.

thanks to all.

If you disable asserts in ImageMagick, you still have asserts in the various delegate libraries (.e.g tiff, png, etc). If you get an assert in your program, you have a logic error. That is what asserts are for, to help detect logic errors.

An easy fix for getting rid of asserts is to define assert in magick/studio.h and wand/studio.h:

• #define assert(x)

This create a NOOP out of asserts.
