Getting error message "dyld: unknown required load demand 0x80000022" with multiple applications.

When using programs such as Evom I keep getting this error message:

"Failed. dyld: unkown required load demand 0x80000022"

How do I fix this?

iMac, Mac OS X (10.5.8)

You should contact the developer of this application. Only the developer can fix this. The application was incorrectly built on a OS X 10.6 machine for a OS X 10.5 machine. The developer can fix this by considering three things:

Using the correct compiler parameters:
gcc-4.2 -mmacosx-version-min=10.5 -isysroot /Developer/SDKs/MacOSX10.5.sdk ...
Using the correct linker settings (setting environment variable before link command). This is required, so that the OS X 10.6 linker will not use the loader command '
```
LC_DYLD_INFO_ONLY' (=
```
0x80000022), because OS X 10.5 does not understand this command:
export MACOSX_DEPLOYMENT_TARGET=10.5
(or setenv MACOSX_DEPLOYMENT_TARGET=10.5)

After this is fixed, one can check if the application was correctly built for OS X 10.5 by running 'otool':

otool -l binary

The correct binary should not contain any '

LC_DYLD_INFO_ONLY'

load commands (only '

LC_DYLD_INFO' commands).
