errors with "make samples"

[wluker]

$ make samples

is printing errors

>>> ERROR : expected option `ceu-features-dynamic`

For example the first sample prints:

##########################################################################
File: samples/test-04.ceu -> /tmp/test-04
Description: Prints "Lua X" every second from three `lua` states.
Features:
 - three `lua` states: one global and two local

Does this mean the sample is failing?

[fsantanna]

Yes, it is still failing.
You should now checkout the master branch and try again:

$ git checkout master
$ make samples

Please, let me know if it works.

Thanks! That fixed that issue, but now the compiler can't find lua5.3/lua.h. On arch linux it looks like lua5.3 is the default lua, so lua.h is /usr/include/lua.h.

On arch pkg-config --modversion lua returns 5.3.4, and pkg-config --libs --cflags lua returns -llua -lm.

[fsantanna]

Ok, this is a bit trickier to fix.

As a workaround for now, you have two options:

1. Disable support for lua in the Makefile:
   • remove --ceu-features-lua=true and -llua5.3
   • only the examples that use embedded Lua within Céu will not compile
2. Edit two files:
   • Makefile: change -llua5.3 to -llua
   • src/c/ceu.c: change #include <lua5.3/*> to #include <lua/*>

[wluker]

I used option 2 and make samples now passes. Thanks.

#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

Ceu looks very interesting. I look forward to learning it.

[fsantanna]

Great!
Thanks for your interest in Céu.
