trouble running linux binaries

[xie_jiabao]

Dear all,

I installed some linux binaries on my laptop running ubuntu 8.04.1 (64-bit) recently. These binaries are generic and meant for all linux flavors. I checked file properties to ensure that these binaries were "executable". I subsequently tried to run these binaries by
1) typing binary_file_name
2) typing ./binary_file_name.

But I get the following error:
./binary_file_name not found

Can someone please tell me how to rectify this problem?

Thanks in advance and best regards,
Xie

Make sure you are in the correct directory when you issue the command.

also check the file type with file command.
