Thank you Sven for quick response >> As you can see your program is linked against the NTPL version of glibc >> on System A (running glibc 2.3) ... LinuxThreads support was dropped in >> 2.4 AFAIK.

(Just run them), the output should somewhat look like this: yaa , correct but is there any compile option in gcc that can ignore glibc versions or ABI changes ?? Is there any problem in "linux-gate.so.1" ?? thank you dinesh Sven Eschenberg wrote: > > Hi there, > > As you can see your program is linked against the NTPL version of glibc > on System A (running glibc 2.3) ...
