Programming :: Code That Doesn't Seem To Be Working Right With Gcc Compilers, But They Do Compile?

Dec 11, 2010

I actually thought there was something wrong with my programming skills.ut after I compiled the same code using Visual Studio, it worked. So here's the code that doesn't seem to be working right with gcc compilers, but they do compile. Note I'm using the Cygwin 3.4.4 version of gcc and 4.5.1 version of gcc from MinGW.

Code: #include <stdio.h>
#include <math.h>
int main()

Programming :: Can't Compile F77 Code Using Gfortran Or G77

Nov 17, 2009

I have legacy fortran 77 code that used to compile seamlessly using g77 on an old machine. I've tried to recompile it on a new machine (old one is dead) using the original makefile, but the linker fails under g77, while there are persisting syntax errors using gfortran. I have two source files readmixed.f and subroutines.f. Under g77 the object files are produced using

Quote:

$ f77 -c readmixed.f -o readmixed.o
$ f77 -c subroutines.f -o subroutines.o

but the linking fails with

Quote:

$ f77 readmixed.o subroutines.o -o readmixed
subroutines.o(.text+0x0): In function `norm1_':
: multiple definition of `norm1_'
readmixed.o(.text+0x3987): first defined here

Programming :: Compile (gcc) Using Code From Other Projects?

Jan 16, 2010

I'm trying to write a helper for the mount utility (mount.truecrypt) and there are some things in the util-linux-ng package that would be helpful. For example, in fstab.c, there is a lock_mtab() function. I want to be able to do something like:

Code:

#include "fstab.h"
int main(int argc, char *argv[])
{
lock_mtab();

[code]....

But I don't know how to compile it. I was trying (naively) something like:

Code:

$ gcc mount.truecrypt.c fstab.c -o mount.truecrypt

But I guess the problem is fstab needs a whole bunch of other stuff. Should I just build the entire util-linux-ng package and then use the output somehow? If anyone is interested in mount.truecrypt (to be compatible with mount and /etc/fstab) you might be interested in giving me a little bit of guidance. I've got enough code to build the actual truecrypt command thus far. In fact, it's useable, but not robust (ie, doesn't lock the mtab, etc). You can browse the source for util-linux-ng here: [URL] and download a tagged release here:[URL]

Programming :: Tell Makefile Not To Compile Debug Code?

Mar 4, 2010

I've been trying to work out a way to stop chunks of code being compiled using a variable in my makefile but can't work it out. What I mean is for example in my code I might have.

/****output comms portdata********/
printf("
debug comms port %d",ReadPort("ttys1);

I only wish this code to be compiled when I'm debugging. What I've tried is using #ifdef with

#ifdef COMM_PORT_DEBUG
printf("
debug comms port %d",ReadPort("ttys1);
#endif

Then in my make file I set COMM_PORT_DEBUG to 1 so

DEBUG_DEFS = COMM_PORT_DEBUG=1

I then thought I could put it into my in my link line

all: $(CC) $(CPFLAGS) $(DEBUG_DEFS) $(INC_PATHS) $(SOURCE) -o $(PROGRAM) $(LIB_DIRS) $(GAME_LIBS)

but this gives a

gcc: COMM_PORT_DEBUG=1: No such file or directory

is there a way to do this sort of thing? Or am I barking up the wrong tree?

Programming :: GDB Doesn't Provide The Correct Line In The Source Code

Jan 23, 2011

I found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

Programming :: Calculations - High Resolution Mandelbrot - Working Code

Feb 25, 2010

I am piecing a Mandelbrot generator up, I have one working to produce a 1,500 x 1,500 picture (which is fairly accurate).

I would like to increase the resolution over 100,000 x 100,000 + (into the millions x millions).

How I can achieve this? What kind of buffer sizes do I need?

(note this code doesnt have any memory allocations yet)

Here is my code so far:

The program outputs the Mandelbrot as a .tga file. I calculated the image on fixed axis of -2 to 2 (on the x and y axis). Image produced: [url]

General :: Compile A Code From A Different Directory?

Jul 14, 2010

I do a lot of programming and I have to compile the code quite often. It's not convenient to move to the directory that contains the source code every time I want to compile it. So is there a way to compile a code from the my current directory (say /home example) without moving to the directory that contains the source. I remember being able to do this but forgotten how.

EDIT: I'm using makefiles to compile. Lets say I'm in the home directory and when I type

make -f /code/make_file

this doesn't seem to work

General :: Compile A C Code Which Uses SSH Library?

Jan 26, 2011

i try to compile a c code which uses SSH library,but i get this error

Code:
libssh.h: No such file or directory

i searched and i found that This happens if a library used for linking is not present in the standard library directories used by gcc.

By default, gcc searches the following directories for header files:

/usr/local/include/
/usr/include/

and the following directories for libraries:

/usr/local/lib/
/usr/lib/

i update my libssh from libssh-0.4.2-1.fc13.i686 to libssh-0.4.6-1.fc13.i686, and there are files called libssh.so.4 and libssh.so.4.0.2 in /ur/lib, but i still can't compile it with this command:

Ubuntu :: Cannot Compile GTK Code After Update To Natty

May 14, 2011

After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.

Even this code will fail to link:
Code:
#include <gtk/gtk.h>
int main(int argc, char** argv) {
gkt_init(&argc, &argv);
gtk_main(); }
(Compiled with the standard commands to compile Gtk+ stuff)

I always get the following output:
Code:
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time'
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time'

Ubuntu Installation :: Install Source Code For Programs To Compile?

Feb 2, 2010

Where do I find the linux-source package and the linux-headers package? Are they on the CD that I can copy to /usr/src (is that the right place...)? Or do I need to download them from the old-releases.ubuntu.com site?

The issue now is that the nVidia installer from their website wants the source code to build the right packages for this machine, however, I do not have the src directory with the source code that it is looking for. Is there some way to give this too it now?

I am running Mythbuntu 7.10
