[Clfs-dev] HELP ME: issue about arm cross toolchain (cannot find gmp.so, mpfr.so...)

[lee sudo]

Dear Andrew,

Thanks for your answer.
It works well after put it all back where it was as you said.

But I find some cross toolchains (e.g. cross toolchain in android source
code) could work well after change its path(anywhere).
This is the script i tested lasy night, it works well and finally succeed.
And i cross compile kernel3.0.23 a moment ago, it also works well.

If i change its path from "/home/sudolee/cross/cross_toolchain" to
"/home/sudolee/cross_toolchain/", this issue occured.
Pls check the log below.
-----log-----
/home/sudolee/cross_toolchain/bin/../libexec/gcc/arm-none-
linux-gnueabi/4.6.0/cc1:
error while loading shared libraries: libcloog.so.0: cannot open shared
object file: No such file or directory
---------------

i know this issue occured due to the path changed, but i want find a way to
avoid this.
Maybe compiling all the library as static could avoid this issue(all the
libaray set by disable-shared). But i
tried many times, build process will abort with some errors, the error log
list below:

Do you know the root cause?
And how to?
