The following fix worked: open build/ProductConfig.cmake file and add the following flags
-Wl, --no-as-needed before the -ldl flag.
This is additional information/bugs for the issue which was closed (? why ?): Compiling on Linux with gcc 7.5.0 ( https://github.com/adobe/XMP-Toolkit-SDK/issues/8 ) . I'm compiling the version XMP-Toolkit-SDK-CC201607. I followed the Readme file and fixed the bugs described here: https://github.com/adobe/XMP-Toolkit-SDK/issues/8. In addition I set up the libuuid as per this description: https://noknow.info/it/os/install_libuuid_from_source?lang=en Here's the gcc version:
I can run "make StaticAll" and it is finished successfully: .ar were created.
If I try to build dynamic libs: "make DynamicAll" - I got the following errors:
