(glitz) struggling to make rendertest

[Patrick Pailhes]

Hi there

I've just downloaded and installed glitz-0.5.1 from Cairo CVS. Now, I
want to test it using rendertest. I've dowloaded the latest rendertest
files from CVS, executed the command ./autogen.sh (backend glitz-glx:
yes), make and make install.

After that, I changed to the directory src and typed make rendertest.
However, there are several linking errors such as:
"src/rendertest.c:296: undefined reference to `render_read_png'" and
"src/rendertest.c:742: undefined reference to `cos'".

When I type make rendertest, it calls "gcc -g -O2 -Wall
-Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes
-Wmissing-declarations -Wnested-externs -fno-strict-aliasing  
rendertest.c   -o rendertest" and that line does not include neither
the Math library nor the necessary files args.c, png.c, etc.

Basically, I'm stuck. I'm sorry to pollute the cairo mailing-list with
this "newbie message" but if anyone has already encountered that
difficulty or knows the answer, I would really appreciate their help.

Thank you.

Patrick

You are right. With cos() you will need to link in the math library (-lm).

Not sure about render_read_png().

Does 'make' and 'make install' complete successfully? If 'make' worked
then you should be all set. If it said "glitz-glx: yes" then you should
have a rendertest_glitz_glx executable in src after typing make.

You don't want to type 'make rendertest'. I'm surprised it's actually
compiling something when you type this. No rendertest binary should be
built only binaries named rendertest_xxx, where xxx is a specific output
backend like glitz-glx, xcb or pixman.

If you want to build just a specific binary e.g 'make
rendertest_glitz_glx' should work as well.
