Dear gnu experts,
I have a question on the GCC version.The followed code is ran succesfully under
one version of GCC,but fail when I use gcc3.4.6.The code is:
#include <fstream>
int set_output()
{
std::ofstream txt_stream;
char txt_stream_file[400];
int status=0;
strcpy(txt_stream_file,"plots/");
strcat(txt_stream_file,"results_");
strcat(txt_stream_file,galdef.galdef_ID);
strcat(txt_stream_file,"_" );
strcat(txt_stream_file,workstring1);
strcat(txt_stream_file,"_" );
strcat(txt_stream_file,workstring2);
if(galplotdef.convolve_EGRET==0)
strcat(txt_stream_file,"_unconv_" );
if(galplotdef.convolve_EGRET!=0)
strcat(txt_stream_file,"_conv_" );
strcat(txt_stream_file,galplotdef.psfile_tag);
strcat(txt_stream_file,".txt");
cout<<txt_stream_file<<endl;
txt_stream.open(txt_stream_file,"w");
return status
}
The txt_stream_file is a file that I want to creat for postscript.When I
compile it with another codes,out:
set_output.cc:46: error: no matching function for call to
`std::basic_ofstream<char, std::char_traits<char> >::open(char[400], const
char[2])'
/usr/lib/gcc/i386-redhat-linux/3.4.6/../../../../include/c++/3.4.6/fstream:695:
note: candidates are: void std::basic_ofstream<_CharT, _Traits>::open(const
char*, std::_Ios_Openmode) [with _CharT = char, _Traits =
std::char_traits<char>]
I translated char txt_stream_file[400] to const char *file,but fail,could
please you tell me how to solve it.Thank you very much.
