llvm dev - Jun 2005 - [LLVMdev] problem compiling the cfrontend on Linux/PPC

Hi,


When compiling the cfrontend for Linux/PPC architecture on a powermac G5, i got
the following error :

It seems that error has to do with gccas which failed to parse a file (?!)

If anyone has an idea...

Hi,

just a guess, but on my x86-64 box I had to compile the gcc frontend
with --disable-multilib

Good luck !

I hate to ask a silly question, but are you using "make bootstrap" to 
build the cfrontend?  Your output looks like gccas is being given a 
native code assembly language file to parse, and I seem to recall that 
that happens if you try doing a "make bootstrap".

Our cfrontend doesn't follow the standard GCC build procedures (mainly 
because we haven't gotten the cfrontend to compile itself with LLVM). 
Instead, you have to follow our CFE build procedures 
(http://llvm.cs.uiuc.edu/docs/CFEBuildInstrs.html) to get it to build.

In fact, i am using the CFE build procedures. I am on instructions 5.
