Hi,
I’ve been using 1.1.8 for a while and although
it works great I wanted to try some OpenGL stuff.
But all the demos require 1.2.0 at least, so
I thought it would be a good time to upgrade.
I downloaded the SDL-1.2.1.tar.gz distribution,
moved the 1.1.8 version out of the way, and
installed 1.2.1 the same way as with 1.1.8:
./configure --prefix=/home/jkort/pkgs/sdl
make
make install
I did rehash and sdl-config --version to be sure
I got the right one. Then I moved to the test
programs directory and tried "make testvidinfo"
which compiles fine:
gcc -DPACKAGE=“SDL_tests” -DVERSION=“1.2.0” -I. -I. -g -O2
-I/usr/X11R6/include -I/home/jkort/pkgs/sdl/include
-I/home/jkort/pkgs/sdl/include/SDL -D_REENTRANT -DHAVE_OPENGL -c
testvidinfo.c
gcc -g -O2 -I/usr/X11R6/include -I/home/jkort/pkgs/sdl/include
-I/home/jkort/pkgs/sdl/include/SDL -D_REENTRANT -DHAVE_OPENGL -o
testvidinfo testvidinfo.o -L/home/jkort/pkgs/sdl/lib
-Wl,-rpath,/home/jkort/pkgs/sdl/lib -lSDL -lpthread
The only odd things I notice are that -DVERSION is 1.2.0
instead of 1.2.1 and the link command gets “-I” flags,
but I doubt that will cause bad things to happen
I was expecting more -l flags, but if the linker doesn’t
complain I wont either. The installed libraries look ok too:
jkort at hip:~/src/SDL-1.2.1/test > ls -l ~/pkgs/sdl/lib/*

/home/jkort/pkgs/sdl/lib/libSDLmain.a
But when I run testvidinfo it goes into a loop before
it does anything, it doesn’t display a window or text.
When I use gdb I get a little more information, but
I don’t understand what it means:
(gdb) file testvidinfo
Reading symbols from testvidinfo…done.
(gdb) run
Starting program: /home/jkort/src/SDL-1.2.1/test/testvidinfo
Error while reading shared library symbols:

===> It went in a loop here, so I pressed control-C and got this:

Any idea what’s wrong ?
I use gcc version 2.95.2
