Hello there, I've found this promising lib, tucked away in the lib directory of my school's network system (running red-hat linux), and have been itching to use it. I wrote a simple prog. using <vga.h>. It compiled fine as per the instructions in the tutorial at www.svgalib.org. I then ran 'chmod u+s' on the out file. But still I get the message: 'svgalib: Cannot get I/O permissions.' What am supposed to do? I wrote down the following bit of code: try1.cpp: #include <iostream.h> #include <vga.h> int main() { int p; p= vga_init(); vga_setmode(TEXT); cout << p; return 0; } compiled as: $ g++ try1.cpp -o try1.x -lvga it compiled fine. Then I did: $ chmod u+s try1.x all was fine. Next: $ ./try1.x and the prompt returns: svgalib: Cannot get I/O permissions. I've downloaded the source-code, and added ROOT_VC_SHORTCUT in the 'Makefile' (but there are so many, in each directory, in which one am I supposed to add that? In the /svgalib-1.4.3/Makefile or /svgalib-1.4.3/src/Makefile?. I've done it in the former.). However it cannon compile the source, because I don't have root rights, and therefore can't write to the /usr/lib directory. I'd very much be grateful, if you could help me out with this. Thank you... Yours Auro :) ------------------------------------------------------------------ Unsubscribe: To: listbot@svgalib.org Body: unsubscribe linux-svgalib
