Thread: gcc linking error

Hi,
I was tryign to install svgalib for using graphics in C. Tried to install svgalib. though i followed the instructions for installation correctly to my knowledge, i am getting the following error when i tried to compile a program.
gcc sample.c -o sample -lvga.c
gives me the following error

/usr/bin/ld: cannot find -lvga
collect2: ld returned 1 exit status

All the header files were installed in /usr/local/includel
so used ln /usr/include/vga* -> /usr/local/include/vga*
since i was trying to link vga.h. but still it did not work
I have used previous gcc -lm to include math.h.
any views why this error occurred?

I'm also having same error.. I think this vga/svga lib is related to display card... not sure but just guess ... if any one got any clue pleaez reply back

Look like your command is not correct, try following compile command:

Code:

cc -Wall -Wstrict-prototypes -fomit-frame-pointer -O2 -fno-strength-reduce -pipe -g -I../include -I../gl   -o sample sample.c  -lvgagl -lvga

Let me know if this works on not!

Also, you may need to configure file /etc/vga/libvga.config. It is Configuration file for svgalib.
If you don't have root level access then Other config file locations is ~/.svgalibrc i.e. /home/yourname/.svgalibrc. If you need to see examples then they are located in /usr/share/doc/svgalib/examples/

Hi Monk,
that did not work. btw my apologies there is no -lvga.c. i did not use the .c
the cc -Wall............
did not work. it still gave the same error.

well something seems to be wrong with the installation. Even as root i did not find the folder vga in /etc. and whats more i am searching for .svgalibrc file !!

Thanks monk it is working now.. at least I'm able to compile program... but this library is not so good... i mean it is not working the way my BC/TC graphics program works. May be I need to configure something.. not sure... any other good graphic library ?

kavi, look like you don't have svgalib installed...btw you got which distro? If it is debain then use following command to install it:

Code:

apt-get install svgalib-bin

i use FC3. perhaps u r right. its not installed well. let me see this weekend. right now got something else to do.
thanx though, will let u know if i work it out.
