I recently upgraded my EMX / Gnu C++ system from
version 08e / 2.2.2 to 08f / 2.3.3. I have noticed
that the libraries have been rearranged.
My problem:
Where did the seekg and seekp functions in
istream and ostream go?
Using the functions under version 08e / 2.2.2 works
just fine, but using version 08f / 2.3.3 gives the
following error(s) when linking (using .o-style object
files and .a-style libraries):
./ccc00096: Undefined symbol _seekg__8iostreamlQ23ios8seek_dir
referenced from text segment
(repeated for each occurence of a seekg-call)
The source might look like this:
#include <iostream.h>
#include <fstream.h>
main () {
fstream internalFile("diskFile", ios::in | ios::app);
internalFile.seekg(1,ios::beg);
// ...
}
The functions are still present in iostream.h, so I guess
this is a sort of library problem. Do I have to use some new
-l option under version 08f to get the libs right? The
example above was compiled with the -lgpp option, both under
version 08e and 08f. The iostream examples in /emx/test seems
to work fine under both versions.
