Run your app (perhaps via a screen session) in gdb and show us 'bt f'. Compile uClibc and your app with something like -g3 -ggdb3 (refer to the documentation of your compiler). Since I have the sources to my_app and uclibc, I don't mind recompile everything as long as it does not impact performance to badly. As long as you don't build with optimizations disabled the speed should be about the same. Would 'sstrip' impact the capability to debug a library and an app ? yes, strip -d (and sstrip for that matter) will remove debug information. You didn't say which version of uClibc you use on which arch, nor if your app uses threads etc. ___ uClibc mailing list uClibc@uclibc.org http://busybox.net/cgi-bin/mailman/listinfo/uclibc

TIA, PS: As you can see this will add a V=2 mode to be verbose in locale-generation, as verbose as it previously was per default. This change is responsible for the vast majority of the patch, unfortunately. I didn't even diff the generated data, so if you can save away extra/locale before applying the patch, please check if the generated data is still the same afterwards (and let me know if it is not ;) I've now installed this as r23677.
