It should be the same as the PHP working directory, but it is not. I have tried looking this on the web, but with not much joy. I found a blog which describes my problem: https://www.ibm.com/developerworks/community/blogs/phpblog/entry/comparing_windows_and_php_working?lang=en In linux the C function `getcwd()` does as expected. It is the same as the PHP cwd, but on windows it always uses the “C:\Program Files\Apache software Foundation\Apache2.2”, whereas in my php script the call ‘echo `getcwd()`;’ returns “C:\www\html” as expected. Please may someone point me in the write direction of how to get to the PHP current working directory in a C/C++ PHP extension.

Thus there is one process which might serve multiple requests in different threads. Each thread needs (from user perspective) its own working directory, thus our thread isolation library, TSRM, provides an API for that: VCWD_GETCWD. Please see TSRM/tsrm_virtual_cwd.h for more related APIs.

In TSRM/tsrm_virtual_cwd.h we have the following: #ifdef VIRTUAL_DIR #define VCWD_GETCWD(buff, size) virtual_getcwd(buff, size TSRMLS_CC) …. The definition of virtual_getcwd further down in TSRM/tsrm_virtual_cwd.h is as follows. Notice that it uses TSRMLS_DC: CWD_API char *virtual_getcwd(char *buf, size_t size TSRMLS_DC); I notice the use of the macro TSRMLS_CC. In TSRM.h we have following: #define TSRMLS_D void ***tsrm_ls #define TSRMLS_DC , TSRMLS_D #define TSRMLS_C tsrm_ls #define TSRMLS_CC , TSRMLS_C It seems that the right macro is not been used or picked up.

Generally I'd appreciate if you could add the issues you mentioned as bug tickets (one per ticket) and assign to the user ab.

Yes, you can either use --with-extra-libs and --with-extra-includes or implement --with-myext=path/to/dep (or as an additional option like --with-myext-deps). Putting the deps into the core deps would work too, but imho that's an unclean way. > - there is the CHECK_LIB() function -> but why the lib is not taken from > there, instead of the deps/bin folder? > not sure to understand this, *.lib files should be in the deps\lib and if those libs are some dll import libs, so the corresponding dll should be in deps\bin Regards Anatol --- ## #74099 — Anatol Belski — 2014-05-09T14:32:20+00:00 URL: https://externals.io/message/73517#74099 · In reply to: #74096 > Hello Anatol, > > > i hope/think this is the "final" hint...

It is any platform alike with the compatibility between different compiler versions. I got it, so that are the bins provided by SAP and of course there are no sources for that. Maybe they provide some static variant of that lib? that might work better (but depends how it's built). Or, don't they provide the vc11 bins, maybe ask support if you can?

The build system on windows mimics autotools so many function names are the same. As well as using --with-.. if you have a dep and --enable-.. if it has none. Regards -anatol
