Unable to start applicaton on Mac OS X 10.5.8

I compiled my 32bit/standalone App on Mac OS X 10.6.4 using Juce 1.53.1 .

One of my Customers uses Mac OS X 10.5.8 and gets this error-Message when starting.
On my 10.6.4 the app just runs fine…

Any ideas?

Maybe you didn’t set the OS target to be 10.5?

maybe this is a silly question. In older releases there was a juce.xconfig to define the target OS.

The only thing i found is MACOS_DEPLOYMENT_TARGET_ppc = 10.4 in the user defined section, i use Juce as a library build.

mhh there are two settings, BASE_SDK and MACOS_DEPLOYMENT_TARGET, i will set this to 10.5, ok will see what happens
