which compiler compiled?
Is there a way I can tell which compiler compiled an executable? I looked at the file with a hex editor and didn't see anything obvious. Lawrence

Yes with some compilers and some executable formats.
E.g. on HP-UX for PA-RISC:
$ aCC leak.C
$ odump -compunit a.out
...
6 0 ANSI C++ leak.C
/tmp
ctcom options = -inst compiletime -diags 523 -inline_power 1 -longbranch 2 -unique_strings on -cachesize 256
B3910B ; A.03.26
Compile Time: Sun Jan 30 2005 11:45:31.000000000 PST
Source Time: Sun Jan 30 2005 11:45:25.000000000 PST
$ what `which aCC`
/opt/aCC/bin/aCC:
HP aC++ B3910B A.03.26
HP aC++ B3910B A.03.25 Language Support Library

In general, no. Specific compilers may embed a version label in the object file. Our compiler (Micro Focus Cobol) embeds a what string in the object which you can display via what my_obj.o The AIX C compiler also embeds a version string, though not in "what(6)" format. If you are on Unix, try strings -a -10 my_obj.o and look for strings such as "version", "release" or synonyms, or "d.d" (where d is a decimal digit). If all else fails, try checking the relevant compiler documentation. Lawrence wrote: > > Is there a way I can tell which compiler compiled an executable?

Compiling Compiler
Hi there, I need some advice/opinion of the experts out there regarding compilers. I have sun cc compiler that supports 64 bit environment. Now, I compile ACK using this compiler.This should give a compiler that supports 64bit environment. Since the output files are in Solaris format, I compile the ACK source *once again* using the just compiled ACK compiler so that I get Minix object and binary files. Now my questions is that does this 2nd version of ACK be able to produce true 64bit code? Sanky wrote: > Hi there, > > I need some advice/opinion of the experts out there regarding...

There's something that sometimes in while it bores me a little bit. How do I know if I need to compile a function/procedure or it will be able to compile "on fly". At the beginning I thought this was related to the paths idl "knew", but this happens for two functions/routines in the same directory.

Writing a compiler compiler
Hello, Firstly, let it be known that I am quite new to the subject of parser generators, and having written only simple parsers for frivoulous grammars by hand have little experience. My objective is thus - to create a parser generator that will eventually generate a parser for a dynamic language. However, my undestanding of different parser types and distinctions between is minimal; but as the web is a good enough resourse please assume my knowledge of those areas. The target for this parser generator would be a language similar to C#, and I have found Jay (a yacc clone to C# and Java). Th...

compiling on different compilers
I am working on a set of functions that involve dynamic memory allocation. I started working with gcc and then moved to Pacific C. The reason was that my only access to gcc was through an ssh connection that I did not have access to all the time, so I got Pacific so I could work on my home windows computer. Then I moved back to gcc, which saved me from some major mistakes. Somehow Pacific C was letting me get away with stuff that was completely wrong. gcc immediately gave me segmentation errors until I got every last thing correct. Is gcc the best for catching mistakes? If not, which on...

Is there a slick way to invent a constant in a program that tells you which compiler you used. I distribute both JET and JavaC versions of my code, and it helps to know on any error dump which version they were using. Right now I manually change a static final just before compiling.
