OK. I decide to use gcc-2.95.3, binutils-2.13.1 and glibc-2.2.3 >> the include files I get from the source files which are used to install >> linux on alpha machine, >> glibc-2.0.1.bin.alpha-linux. >> Are there any more files that I need to get?? > You should prefer to use headers and libraries for your real target, >For instance RedHat or SuSE 7.1/Alpha uses 'glibc-2.2.3' and even >RedHat 6.2/Alpha used glibc-2.1.3...

I think that there is something that I need to clarify. I have no alpha machine. The reason I make this cross-compiler is that I want to make my own benchmark programs for running SimpleScalar Toolkit. SimpleScalar3.0 only support two computer architecture:PISA and Alpha. So I have to make the benchmark programs on my machine(i686-pc-linux) whick should be make on an Alpha mechine(alpha-dec-osf). I don't know whether I say it clearly this time. :) >> 2.

Do you have these two files, Can you mail them to me??? >Cheers, Kai ”””” Shen Yingzhe yzshen@mail.ustc.edu.cn 2002-12-17
