I am unable to compile C++ program in terminal. Whenever I try to add "#include<iostream.h>" it shows an error and thats why I can not use "cout" and "cin" functions. I installed g++ for this but the problem persists.
View 4 RepliesI 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

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]

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?
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>

I have a problem in programing pseudo terminal. In the book APUE (advanced programing in the unix environment) in chapter 15.4: coprocess gives an example of using pipe to operate another program, that provide its input and read its output: Figure 15.18. Figure 15.19 is filter to add two numbers using standard IO. The author said that you must flush the IO buffer in the program which are operated through pipe by another program, however, we cannot add fflush to the source code and re-compile the whole program if we need to use it in another process. It said that pseudo terminal can solve this problem, but I have tried in fedora12 with forkpty call and fail. Source code as follows:
The main process:
Code:
#include "common.h"
#define LINESIZE 256
int main()
{
int fd[2];
pid_t pid;
if( socketpair(AF_UNIX, SOCK_STREAM, 0, fd)<0 ) {
perror("create socket error");
exit(1);
}
int master;
struct termios tm;
if( tcgetattr(STDIN_FILENO, &tm)<0 ) {
perror("tcgetattr error");
exit(3);
}
struct winsize size;
if( ioctl(STDIN_FILENO, TIOCGWINSZ, (char*)&size)<0 ) {
perror("ioctl error");
exit(4);
}
setbuf(stdout, NULL);
pid=forkpty(&master, NULL, &tm, &size);
if( pid<0 ) {
perror("create process error");
exit(2);
}
else if(pid>0) {//parent
close(fd[1]);
char line[LINESIZE];
memset(line, 0, LINESIZE);
while( fgets(line, LINESIZE, stdin)!=NULL ) {
write(fd[0], line, strlen(line));
memset(line, 0, LINESIZE);
int n=read(fd[0], line, LINESIZE);
if(n>=0) line[n]=0;
printf("%s", line);
memset(line, 0, LINESIZE);
}
} else {//child
close(fd[0]);
if( fd[1]!=STDIN_FILENO ) {
if(dup2(fd[1], STDIN_FILENO)!=STDIN_FILENO) {
perror("dup2 error");
exit(1);
}
}
if( fd[1]!=STDOUT_FILENO) {
if(dup2(fd[1], STDOUT_FILENO)!=STDOUT_FILENO) {
perror("dup2 error");
exit(2);
}
}
close(fd[1]);
if(execl("./add", "add", (char*)0)<0) {
perror("exec error");
exit(3);
}
exit(0);
}
//parent
wait(NULL);
return 0;
}
The add program reads a line and get two numbers and return the sum of them.
Code:
#include "common.h"
int main() { int n1, n2;
char line[256];
memset(line, 0, 256);
while( fgets(line, 256, stdin)!=NULL) {
sscanf(line, "%d%d", &n1, &n2);
printf("%d", n1+n2);
fflush(NULL); /*the program does not work without this sentence why?*/
memset(line, 0, 256); } return 0; }
I downloaded wine from a windows laptop, but because you have to have a computer running Linux to download it as a .deb package, I had to download the source code as a tar. bz2.
Does anyone know how I compile it and make it executable?
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
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:
