Help with GCC

[Andrew Luande]

Please help me if you can

 

am hoping someone can tell me where am going wrong with my installation of
SSH 3.5p1.  I have a netrax1 that I have just installed Solaris 8.  I
downloaded the SSH software from the site.  When  it compile it does this

 

# ./configure

checking for gcc... gcc

checking for C compiler default output... configure: error: C compiler
cannot create executables

 

and the config.log looks something like this

bash-2.05# more config.log

This file contains any messages produced by compilers while

running configure, to aid debugging if configure makes a mistake.

 

It was created by configure, which was

generated by GNU Autoconf 2.53.  Invocation command line was

 

  $ ./configure

First of all, this is not appropriate for gcc@gcc.gnu.org, and it is
even less appropriate for gnu@gnu.org.

And second, you do not have a C compiler installed, or your configure
script is not able to find that compiler.


Please do *not* respond to this message to either of the two lists.

You can't get cycle-accurate life time info in the register allocator
unless you have a combined register allocator and instruction scheduler.
 We don't have that.  They are separate passes.  Combining them is
difficult.

We do have life time info at the RTL instruction level, but this info
tends to be either internal to each register allocation pass, or not
specific enough for your needs.  You may or may not be able to do
anything with this info.

The register allocator does not emit instructions (other than reloads
emitted by reload), so you can't do this in the register allocator.  You
probably have to do this in final, when RTL is emitted as assembly language.

You might be able to do something useful with REG_DEAD notes, but they
are probably not guaranteed to be accurate when we get to final.  You
could try scanning following instructions for REG_DEAD notes, to see
where registers die.  Worst case, you might have to create your own life
time info by scanning all of the RTL instructions in a function.  You
could do this in a MACHINE_DEPENDENT_REORG pass.

You will probably need to spend some time studying the gcc sources in
order to do anything useful here.

Hello Everyone,
    Greetings! I apologize ahead for asking an non-specific question. I
have a question about the liveness analysis. This is what I wanted to
do.

I want to check to see if an instruction is live after a certain number of
stage. (eg. 3 cycles)

if (INSN is not live for more than 3 cycles)
   Mark it as "not_live" (NOT the same place as dead code marking)
else
   Mark it as "live"

Pass this "live/not-live" flag to the register allocation process so that
it can output instruction in such a way (please see example below) (I want
this information to be passed into .md stage)

if (live)
  print "add.live r1,r2,r3"
else
   print "add.notlive r1,r2,r3"

I would also like to do it on the OpenRISC processor. Also, would like to
NOT change the GCC sources as much as I can.

I would appreciate if anyone could point me in the right direction to go
about doing this.

Thanking You,

Yours Sincerely,

Balaji V. Iyer.

PS. CC's greatly appreciated.

This isn't the right list for this type of question, however, you need
to install the developer packages - this is usually an install option.

I just bought redhat9 and i was wondering if this program is already on my 
computer?  I have tried to compile stuff but it comes up invalid comand.  I 
dont know how to get all this stuff started can you help???

What platform / OS are you programming under ?

Basically, the OS should take care of swapping your host program to virtual 
memory. Just make sure the system("other program") call is blocking (ie., 
your host program stops and awaits for the other to finish).

Hi,
I am developing a C program in gcc environment. The problem is that I have to make a system call to execute another program from my main program (i.e. system("program name")). The other program which I am calling is not written in C, and I dont have its source code, so basically I just call it to execute and it returns the output in a output file. I have to take up this output and use it in the main program, but until and unless it writes the output the main program has to wait without using substantial resources (because the other program needs lots of memory and CPU processing). These calling of the other program and execution based on its output happen in a loop. Can you suggest me how to handle this situation.
Thanks in advance

Put the directory containing the gcc executable in your PATH.

If you are using a shell like csh/tcsh, type "rehash".

If it still doesn't work, ask your system administrator for assistance.

I can't get gcc to work on my SPARC/Solaris 7 machine.  Whenever I try to
compile a program it says that gcc cannot be found.  Thanks in advance.
