How to multiple paths with header dependency
nixfreak opened this issue · 5 comments
Hello,
I am trying to create wrappers for efl libaries starting with Elementary https://git.enlightenment.org/enlightenment/efl/src/branch/master/src/lib/elementary
The only problem I am having is that when I want to wrap Elementary.h there is multiple dependencies in other directories
Here is my code:
`import futhark
importc:
sysPath "/usr/lib/gcc/x86_64-pc-linux-gnu/12.1.1/include"
path "/usr/include/elementary-1/Elementary.h"
path "/usr/include/eina-1/Efl_Config.h"
static:
writeFile("enim.c", """
#define ELEMENTARY_IMPLEMENTATION
#include "/usr/include/elementary-1/Elementary.h"
#include "/usr/include/eina-1/Efl_Config.h"
""")
{.compile: "enim.c".}
`
Here is my error:
nim c -d:Debug --passL: "$(pkg-config --cflags --libs elementary)" enim.nim

The example in the README is for libraries that have to be compiled into your project. You appear to link existing objects to your binary so the entire static section can be removed. Also if you pass path to folders instead of files it will load any required files from that folder. Try something like this instead:
import futhark
importc:
sysPath "/usr/lib/gcc/x86_64-pc-linux-gnu/12.1.1/include"
path "/usr/include/elementary-1/"
path "/usr/include/eina-1/"
"Elementary.h"
"Efl_Config.h"With a build command like the one you used.
Ok after adding all the dependencies are received this error now:
nim c -d:release --passL: "$(pkg-config --cflags --libs elementary)" enim.nim

Is this a memory issue?

Nah, it's just the Nim compiler not allowing the parser to parse such a large JSON object, it believes it has reached an infinite loop. Just increase the max iteration loop count with --maxLoopIterationsVM:
Ok that worked I now have a 123K executable file. Thank you now on to calling those functions and see if I can do something with them.
Ok so I should be able to call this binary from nim , do you have documentation for that ? Also is there a way to actually see the functions ? Right now I'm running Futhark again and tee out a log.
Call which binary from Nim? You import functions that you should then just call like normal Nim functions. You can see the functions in the generated Futhark cache file, or by nim doc on your module.
