Topic: compile mod_ftp for Apache 2.4.x ?

[lunter]

Is it posible to compile mod_ftp?

It is ftp protocol support for Apache.

There is a binary at http://www.apache.org/dist/httpd/binaries/win32/

There is one problem: do not work on Apache 2.4

[tdonovan]

I tried some changes to mod_ftp to make it compile with Apache 2.4. It is not nearly ready to check in yet, since I haven't tested it on Unix; but it seems to work OK on Windows with the ApacheLounge 2.4.1 binary: httpd-2.4.1-win32.zip 28 Feb '12.

I put all the mod_ftp changes that I have so far in a patch file.

You will need these tools installed to compile mod_ftp on Windows32:

the Subversion client to get the current mod_ftp source code.
a patch utility to apply the patch file (choose "Complete package, except sources")
.NET Framework 4, which is a prerequisite of the Windows SDK
the Windows SDK for Windows 7 (use this same SDK for all Windows systems: WinXP, Win7, etc. It includes a VC10 compiler.)
the Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)

To compile mod_ftp, open a "Windows SDK 7.1 Command Prompt" from the Start menu, change to a working directory (with the patch file in it), and do this:

Thanks Tom,

The core_filter_ctx had me stumped.

[tdonovan]

It baffled me too! I'm not very enthused about the fix in the patch.

I'm not sure which is true:

* Each filter is now supposed to define core_filter_ctx as they see fit, like in server/core_filters.c (and now also in ftp_data_connection.c) I don't see it used anywhere else.

* It's a mistake, and struct core_filter_ctx should be defined in include/http_core.h, along with core_ctx_t.

I guess I've been away from the httpd code for too long now.

-t-

p.s. It looks like Stefan F. noticed the problem too, see Rev 1235019. Not in any release yet - but the right fix will be to call ap_create_core_ctx when it is available.

I thought they squeaked all this in before 2.4.1
http://svn.apache.org/viewvc?view=revision&revision=1240478

You also learned me some more as this came as a complete surprise;

#if AP_MODULE_MAGIC_AT_LEAST(20111203,0)
/* AP24 request fields */
r->useragent_addr = c->client_addr;
r->useragent_ip = c->client_ip;
#endif

I was a bit curious for a time why all the CLIENT_IP & CLIENT_ADDR and not simply

#if AP_MODULE_MAGIC_AT_LEAST(20111203,0)
#define remote_ip client_ip
#define remote_addr client_addr
#endif

but I can see a case where peer_ip/peer_addr might need to be used and the above would give it client_ip/client_addr instead. I've not run into a case where both have been in use yet, but I'd bet there is something out there that does.

Thanks again.
BTW, there is a PR for this

Hi

I'm having a problem compiling mod_ftp with VC10 towards apache 2.4.1

Tried to follow directions above, but I get a lot of "error LNK2019: unresolved external symbol __imp_apr_..."

I'm really doing "google hacking" here, but I get the feeling that the compiler for some reason adds the "__imp_" thing and then the linker can't match that towards the VC10 build of apache 2.4.1.

I wouldn't mind some advice on how to proceed (or maybe someone could do the compile for me )

[glsmith]

you compiling at command line or from the IDE?

[RichardWH]

Ahh... Could of been more clear on that (sorry)

Short answer: cmd line

Long answer:
Tried to follow tdonovans post from "Thu 22 Mar '12 18:42"

Noticed that when I open the command prompt it says "Targeting Windows 7 x64 Debug", but I thought it shouldnt matter since the make file says win32 and NDEBUG

[glsmith]

ok, well the error says it's not finding one or both of libapr-1.lib or libaprutil-1.lib, which should be located in INSTDIR\lib

So, is INSTDIR pointing the base folder of an already precompiled Apache 2.4.x? If yes, are those two files listed above located in INSTDIR\lib?

As far as Windows 7 Debug 64 bit, it will build a debug build. Edit the properties of the CMD Shell shortcut and add to the end of the target:
/xp /release

[RichardWH]

Well, well, well ...

It was a while ago, programing ..
Couldn't make it work, until I realised I have to delete the old .obj files (to let make do its thing)

Anyway, got working by

Started the "Windows SDK 7.1 Command Prompt"
(C:\Program Files\Microsoft SDKs\Windows\7.1)

cd bin

setenv /release /x86

Then it was just to follow tdonovans posting

Thanx a million for setting me on the right track (and a really god site)

(copied the mod_ftp files and VIOLA - let there be FTP on Apache 2.4.1/VC10)

Do it have the binary compiled to download?

[glsmith]

I have VC9 builds here: https://www.apachehaus.net/modules/

[Diammo]

It work. ty
