[PHP-DEV] 4.0.4 Win32 compilation issues From: Marc Boeren (M.Boeren <email protected>)
Date: 01/03/01

Hi!

I've downloaded the 4.0.4 source from the site, did all the stuff* to get it
to compile (with a lot of warnings (see below) about 'inconsistent dll
linkage. dllexport assumed' and others, how do I get rid of those without
altering the warnings switch?) under WinNT4 using VC6 (with all the default
projects), and it all seems to work ok, except for the debug version, which
hangs somewhere opening the php.ini-file... here's the code that leads to
the error...

php_module_startup ... line 877 + 5 bytes
php_config_ini_startup ... line 710 + 5 bytes
php_init_config ... line 206 + 23 bytes
php_fopen_with_path ... line 410 + 20 bytes
php_fopen_and_set_opened_path ... line 235 + 11 bytes
expand_filepath ... line 519 + 17 bytes

CWD_API char *virtual_getcwd(char *buf, size_t size)
{
        size_t length;
        char *cwd;

        cwd = virtual_getcwd_ex(&length);

        if (buf == NULL) {
                return cwd;
        }
        if (length > size-1) {
                free(cwd);
                errno = ERANGE; /* Is this OK? */
                return NULL;
        }
        memcpy(buf, cwd, length+1);
        free(cwd);
        return buf;
}

It hangs on the 'free(cwd);' line just before the end, reporting an
assertion failure on _BLOCK_TYPE_IS_VALID(pHead->nBlockUse);
I can't see anything wrong with the code, and it works OK in the
release-version, where there are no assertions for the heap.

Anyone got any comments on this to help me get started with actual
development?

Cheerio, Marc.

* I had to modify the lines for the bison parser in the MSVC projects
because they complained about the -S option, they now look like:
 bison -o zend_ini_parser.c -v -d -p ini_ zend_ini_parser.y
