cc1plus take too much memory

cc1plus take too much memory

[mahmoodn]

Hello,
I do not know why gcc process (cc1plus) take too much memory during
compilation (over 600 MB). according to system monitor, 

total:      658 MB
RSS:     651 MB
shared:  11.2 MB

Don't you think it is abnormal?>-( maybe there is a memory leak in gcc. 

I have to say that I use gcc 3.3

A couple of things:

  gcc 3.3 (released May 2003) is no longer being developed.  Anything
  it does today it will always do.

  We don't know if this is abnormal because we don't know what you
  were trying to compile.

I will work around with my code to get it ready for newer versions of gcc,
but untill then:

Run the program you were trying to compile through "gcc -E".  How big
is the resulting text?  Are there any particularly long functions in
your program?  That kind of thing.

But I don't know how pointful this will be, given that gcc 3.3 is no
longer being developed.

I have long functions with many typedefs. Have they any effect?

in the directory than contain makefile, the result of "gcc -E" is:
[naderan@Milky-way VVc_diagram_2]$ gcc -E
gcc: no input files

I use "make" instead to compile the project. what should I do then?

Compile whichever file is causing the trouble with gcc -E to extract
the preprocessed source.

Have you ever compiled a C file without using make?

I did what you said, the largest file is 768KB.
is good or bad?

It's large, but not unreasonably so.  I'm not sure what's causing the
huge expansion in memory use.
