Question about egcs building w/native compiler

[nnorwitz@arinc.com]

     Jeff:
     
     Thanks for you input.  This is what the final results were:
     
     ./configure
     make bootstrap
     ...
     ...
     // stage 1 apparently completes fine
     // starts building stage 2 with stage1/xgcc
     stage1/xgcc -c *.c  // this goes well not the exact command, of course
     // but then it tries to link w/cc
     
     cc -o genattr genattr.o alloca.o // and some other .o's
     
     This fails.
     
     So what I did was just tell make to use the xgcc compiler:
     
     make CC=stage1/xgcc CFLAGS='-Bstage1'  // I think that's the flags
     
     This built everything.  For whatever reason, cc wouldn't link, perhaps 
     alloca had been compiled with xgcc and couldn't link with cc?
     
     I don't know if fortran and the other languages built or not.  Don't 
     care, either. :-)  I did get gcc and g++ built and apparently working.
     I was just surprised I had to do the extra step.  I looked 
     (half-heartedly, I admit it) in the docs to try to find info before 
     asking, but couldn't find anything relevant (I did find the bootstrap 
     in the home page which was very helpful).  It was a little harder to 
     find info, since the doc structure seemed a little different than what 
     I'm used to.
     
     This is a just bought computer and possible a very new rev of the cc 
     compiler on AIX 4.2.1, I can check if you want.
     
     There was one thing I was a little surpised about.  I think it 
     probably is an old "problem."  gcc invoked without files, issues the 
     message: "gcc: No input files" g++ invoked without files, attempts to 
     link and then the linker provides an error (of course).  No crashes or 
     anything, but I expected similar behaviour between gcc and g++.
     
     I definitely believe in egcs and look forward to using it.
     
     Thanks again,
     Neal

Well, it should be trying to build fortran in stage2 :-)  And that should 
be OK since it should be using stage1/xgcc to build the stage2 compiler.
     
You might try building in a separate directory from the source using gnu 
make (ala the install instructions).
