[LLVMdev] install and the strip command

[Reed Kotler]

The problem seems to be the executable

llvm-config-host

this is the wrong file type for the machine that I'm on.

I'm building a hosted mips clang/llvm compiler, starting by compiling 
llvm with clang/llvm on x86 producing a mips executable.

The question then is where to run install.

If I run install on the mips target, then file llvm-config-host is an 
x86 executable so strip will fail.

../install/bin/llvm-config-host: ELF 64-bit LSB executable, x86-64, 
version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 
2.6.24, BuildID[sha1]=0x64e37bd56c1edc16be1447ec301bfce3f207477d, not 
stripped
rkotler at mipsswbrd006-le:~/caviumllvmwclang/build$


If I tried to do the install on the host, there would be a bigger 
problem because then strip would fail on every other executable.


So the main problem is that install should not be trying to strip
rkotler at mipsswbrd006-le:~/caviumllvmwclang/build$ which strip
/usr/bin/strip
rkotler at mipsswbrd006-le:~/caviumllvmwclang/build$

Perhaps I just need to delete that file from the build directory.
