Hi Kraiser, > http://stackoverflow.com/questions/1857296/can-gcc-on-ubuntu-on-a-64-bit-machi > ne-generate-an-executable-where-long-is-32-bit > It's my problem actually any possible way to do that ? Yes. Take the Ubuntu source code. Change the Ubuntu ABI. Call your new OS something else, such as Kraiser GNU/Linux. Applications compiled on Kraiser GNU/Linux will then have your OS's ABI which would have 32-bit sized long. Executables compiled for Kraiser GNU/Linux will not run on Ubuntu. (I've done something similar, back in the day when I was playing around with Mandrake 6.1 "helios" Linux. I never released my "Eljay GNU/Linux" to the public, nor intended to. It was just for fun and learning, and never escaped the dark confines of my basement. There will be bugs.) > well -m32 isn't actually what i'm looking for because it compiles code for > 32-bit enviorment along with pointers(32 bit) i need pointers to be 64-bit > but long = 32bit just like it is on Windows LLP64. Ubuntu's ABI is different from Windows' ABI. > If the feature isn't exist maybe it would be awesome to add in future > releases of GCC :? That's not a GCC-ism. It's the OS ABI-ism.
