 |
|
I have a small C++ example program and thought I can compile it with SCC. Unfortunately it seems that the STL library is unknown to SCC. Is this correct?
| Code: | #include <iostream.h>
#include <string.h>
#include <vector.h>
#include <fstream.h>
#include <math.h>
#include <time.h>
#include <iomanip.h>
string LOCATION;
int Imax, Imin, dI, dtheta;
int main(int argc, char * argv[])
{
int n=0;
for (n=0; n<argc; n++)
{
printf(argv[n]);
printf("\n");
}
string tmp;
tmp = argv[2]; // Imax
from_string<int>(Imax, tmp, std::dec);
tmp = argv[3]; // Imin
from_string<int>(Imin, tmp, std::dec);
tmp = argv[4]; // dI
from_string<int>(dI, tmp, std::dec);
tmp = argv[5]; // detheta
from_string<int>(dtheta, tmp, std::dec);
return 0;
}

As far as I know SCC can handle templates but the standard library is not provided for you.
There is a good chance that you will be able download the source for the library from http://www.sgi.com/tech/stl/vector and build it for yourself. |

Thanks Paul.
It is possible to download the files. Several files starts with stl_... and can be copied without any difficulties into the Silverfrost include directory. However, several files (ALGOBASE.H, DEFALLOC.H, DEQUE.H, ...) need to be overwrited. I tried several possibilities and it did not work.
Questions:
1.) Can I overwrite the the exisiting files in the include directory with that downloaded from the STL site?
2.) For a Fortran project I can specify include paths in the project options. This option is not available for SCC.
3.) What do you exactly mean by building the library for myself. Should I make a dll, lib or add the whole STL library as an include. |

1) I would compare the two versions. If they are consistent (i.e. the common parts are identical) then I would use the download. Otherwise I would keep copies of the old files and use the downloads on a trial and error basis.
2) You don't need to add include files to the project. If you do (and there is no INCLUDE folder offered) then you can add them if you wish but you will need to "Exclude" them from the build process via the file properties dialog.
3) I would try building a DLL using only the parts I need. |

My colleague informed me on a previous thread where similar difficulties were encountered. Based on this information the code I tested will not work.
However, I would like to give you the background to the idea. Our FEA software has an option to specify a user control program that is executed after each timestep in a transient analysis. This allows the user to change/vary certain parameters during a simulation. I was hoping that I can introduce Silverfrost to them by encouraging them to get the Personal Edition - and finally a licence. |

The control programs we use are no rocket science. However, using the examples as provided by the FEA software can not be compiled by SCC. Since I would really like the guys to start with Silverfrost ans especially FTN95 I changed the code using "old style" C to convert the command line arguments to float.
| Code: | #include <stdio.h>
int str2int(char * str_int)
{
int i;
if(EOF == sscanf(str_int, "%d", &i))
{
//error
}
return i;
}
float str2float(char * str_float)
{
float f;
if(EOF == sscanf(str_float, "%f", &f))
{
//error
}
return f;
}
int main(int argc, char * argv[])
{
int i;
float f;
if (argc != 5)
{
printf("usage: %s",argv[0]);
}
else
{
for (i=1; i < 5; i++){
f = str2float(argv[i]);
printf("%f\n",f);
}
}
