Missing unsigned char

The unsigned char type is missing from the INT_TYPES array on Compiler.php

Work with CGO Shared library header

Hey,

I'm currently working on a project, in which I want to call Go Function in PHP. I created a c-shared library in go with some basic functions:

import "C"
import (
	"fmt"
)

//export print
func print(out *C.char) {
	fmt.Println("[GO print] " + C.GoString(out))
}

//export sum
func sum(a C.int, b C.int) C.int {
	return a + b
}

func main() {}

The header file created by go self looks like:

/* Code generated by cmd/cgo; DO NOT EDIT. */

/* package Go */


#line 1 "cgo-builtin-export-prolog"

#include <stddef.h>

#ifndef GO_CGO_EXPORT_PROLOGUE_H

I want to parse it as followed:

$lib = (new FFIMe($libPath . "libutil.so"))
            ->include($libPath . "libutil.h")
            ->build();

I get the following error:
Unknown directive found line {"exception":"[object] (LogicException(code: 0): Unknown directive found line at /var/www/html/vendor/ircmaxell/php-c-parser/lib/PreProcessor.php:140)

I would greatly appreciate any suggestions or ideas that you may have on this topic.

suppress FFIMe warnings

Hi, thanks for this great library!

I'm wondering if you'd consider a PR that would add an option to suppress these warnings? Maybe just a private flag on the class defaulting to true, that can be set with a method $ffi->showWarnings(false)->codeGen('File.php') or something.

Warning from: use double

Hey there - is there a way to disable the use double statement from being generated in the FFI wrapper?

See this issue here for reference:

extism/extism#142

Forgive my naivety, but I'm not sure what that statement does, but it consistently produces a warning printed to output.

PHP Notice: Undefined variable: mainOffset in /home/projects/vendor/ircmaxell/php-elf-symbolresolver/lib/Parser.php on line 79

it seems that we need new release

Help with a header file

Hi @bwoebi

This isn't directly related to FFIMe however not sure how will it help. I'm still exploring how to use FFIMe after your latest fixes allowing it to at least generate the wrapper file (not sure if wrapper is the right word).

So I have the following header file, and I'm struggling with the FFI:: code that should be able to operate on the db_prepare_request function. I went down to working on casting and passing direct addr, however without luck and always crashes in the binary shared object of the library.

Would really, really, appreciate if you could help here.

Here's the header file.

#ifndef _DB_H
#define _DB_H

typedef struct db_client db_client_t;

/* Initialize the database library - must be done once per process! */
int db_init(void);

/* Client create/free */
db_client_t *db_create_client(void);
void db_free_client(db_client_t *c);

/* Prepare a request, before calling execute. If arg_lens is NULL, strings are
 * processed as null terminated. Otherwise lengths are taken from the separate
 * size_t array.
 */
int db_prepare_request(db_client_t *c, int args_count, const char **args, size_t *arg_lens);

/* Execute request; returns 0 on success. */
int db_execute(db_client_t *c);

/* Read chunk from reply. Chunking depends on internal database representation
 * so make no assumptions.
 *
 * Every call returns a pointer and updates chunk_len. When no more chunks
 * are available, NULL is returned.
 */
const char *db_read_reply_chunk(db_client_t *c, int *chunk_len);


#endif  /* _DB_H */

All I managed to have with no crashes is $ffi = FFI::load("db.h"); $ffi->db_init(); $client = $ffi->db_create_client();

Also, not sure if FFIMe would help making things easier right here as the examples doesn't include enough examples for various use cases for non experts.

Many thanks!

Could not find header file: limits.h given context, trying to operate on libcurl

Hi @ircmaxell

Running the following code, not necessarily on this specific version of libcurl, but other versions on different Linux distros as well.

<?php
require __DIR__ . '/vendor/autoload.php';
(new FFIMe\FFIMe("/usr/lib64/libcurl.so.4.7.0"))

    ->codeGen('curl\\curl', __DIR__ . '/curl.php');
require __DIR__ . '/curl.php';
$libc = new curl\curl;
//$libc->printf("test\n");

I am getting the following, and here's the exact curl.h file I currently have https://github.com/curl/curl/blob/curl-7_82_0/include/curl/curl.h

I tried to lookup for where limits.h exists on my system, and this was the result.

/usr/include/limits.h
/usr/include/c++/12/tr1/limits.h
/usr/include/linux/limits.h
/usr/lib/gcc/x86_64-linux-gnu/12/include-fixed/limits.h
/usr/lib/gcc/x86_64-linux-gnu/12/install-tools/include/limits.h
/usr/lib/gcc/x86_64-redhat-linux/12/include/limits.h

Not sure why there's an issue with limits.h.

Any idea what am I doing wrong?

Uncaught PHPCParser\Error: Syntax error, unexpected IDENTIFIER(int_least8_t)

Hi @bwoebi

Attempting to use Redis's https://github.com/redis/hiredis library, I'm getting the following error.

PHP Fatal error:  Uncaught PHPCParser\Error: Syntax error, unexpected IDENTIFIER(int_least8_t), expecting ',' or ';' on line 395 in ~/hiredis/vendor/ircmaxell/php-c-parser/lib/ParserAbstract.php:236

The hiredis.h file itself doesn't include any int_least8_t yet one of its dependencies stdint.h which is a glibc-headers package included header.

I guess the part of interest in the stdint.h file is the following.

/* Small types.  */

/* Signed.  */
typedef __int_least8_t int_least8_t;
typedef __int_least16_t int_least16_t;
typedef __int_least32_t int_least32_t;
typedef __int_least64_t int_least64_t;

/* Unsigned.  */
typedef __uint_least8_t uint_least8_t;
typedef __uint_least16_t uint_least16_t;
typedef __uint_least32_t uint_least32_t;
typedef __uint_least64_t uint_least64_t;

Any idea why?

I am trying to understand how your library works and what its used for and finding issues like that along the way.

Missing int_ptr classes

I'm playing around with IUP (a gui toolkit written in C which seems a nice test case for this generator) and the library uses references to integers, below code is needed here:

$class = array_merge($class, $this->compileDeclClassImpl('int_ptr', 'int*', $className));
$class = array_merge($class, $this->compileDeclClassImpl('int_ptr_ptr', 'int**', $className));
$class = array_merge($class, $this->compileDeclClassImpl('int_ptr_ptr_ptr', 'int***', $className));

The code I attempted to use:

(new FFIMe('/app/libnetsnmp/usr/lib/x86_64-linux-gnu/libnetsnmp.so.30'))
    ->include('/app/libc-dev/usr/include/x86_64-linux-gnu/gnu/stubs.h')
    ->include('/app/libc-dev/usr/include/x86_64-linux-gnu/sys/cdefs.h')
    ->include('/app/libc-dev/usr/include/stdio.h')
    ->include('/app/libnetsnmp-dev/usr/include/net-snmp/library/mib.h')
    ->include('/app/libnetsnmp-dev/usr/include/net-snmp/library/parse.h')
    ->codeGen('Test\NetSnmp', __DIR__ . '/test/NetSnmp.php')
;

Since I'm running on macOS I had to download all needed header files and unpack them. While that might pose a problem it actually makes sure I'm not mixing different versions. I used the bog-standard packages from Debian.

For your convince I included unpacked files with this issue. They're originating from amd64 debs from Jessie: https://github.com/ircmaxell/FFIMe/files/4600524/libs.zip
