Jonathan:
Thanks for the response. Your advise on breaking up the build
fixed the problem.
Question: With gcc is there an upper limit on the object code
size of the final linked application? How about the *.O files?
Currently I am at about 50.5MB.
Currently I use static linking for portability, avoiding missing
dll issues.
For larger applications will it be necessary to break up the
executable using
dynamic link libraries, thus loading a block when and if it is actually
called?

Gentle People:
When Building a rather large project gcc produces the following error:
"Out of memory for code representation:" See the details below.
What is the best or simplest way to fix this?
1) Will using 64 bit via the -m64 flag fix this?
That tells the compiler to produce 64-bit output, it doesn't change
how much memory it has available, and is likely to use more memory to
represent the larger pointer types.
or
2) I am currently building the project with single gcc call. (The slow way)
Due to some legacy issues with GTK/Cairo and extern variables one big build
seems to work. Would it be better to compile each .C File to a .O file and
then
link (Faster way).
Do you mean you've put all the code in a single file? If yes, then of
course splitting it up into smaller files will use less memory.
3) I am using an older gcc 3.4.6 on Solaris 10.
Good grief.

This error isn't even coming from GCC, it's coming from the assembler,
which is part of Solaris and not part of GCC. It's trying to assemble
a file that is at least 15 million lines long. That's probably your
problem. Try splitting Main.c into smaller files.
