Hi,

I'm not sure i'm posting in the right section :/
If not please apologize me and direct me to the right place :)
(and sorry for my poor english, i'm not a native speaker)

Here is my problem :
I want to build a boinc app for Linux 64bits (x86_64).
I've downloaded the source code of boinc, built it on my Ubuntu64bits
I've built the example_app (UpperCase) with my Linux64bits
And i thought it was all i have to do !

But when running the app, it seems that ia32_libs is needed to run my app on 64bits host.

Is it normal ? Is there a way to avoid that ? How can i be sure that my app is really compiled in 64bits ?
(any options to add in the Makefile ? like -m64 for gcc ?)

Thanks for your help.

Some versions of Linux don't provide the 32 bit files which are necessary to run 32 bit apps on 64 bit systems.
You can find out how to get the extra files in this section of the BOINC Wiki article: Installing_on_Linux.

Hi,

Thanks for your replies.

I don't know what went wrong the first time, but my 64bit app is now really 64bits and independent of ia32-libs :)

Thank you very much for the command "file" i didn't know it and it's very useful.
