OS X compile errors

  • libproxychains.c:224: error: conflicting types for `connect'
    /usr/include/sys/socket.h:513: error: previous declaration of `connect'
    libproxychains.c:295: error: conflicting types for `getnameinfo'
    /usr/include/netdb.h:257: error: previous declaration of `getnameinfo'
    libproxychains.c:313: error: conflicting types for `gethostbyaddr'
    /usr/include/netdb.h:225: error: previous declaration of `gethostbyaddr'

    The conflicting declarations are:

    int connect (int sock, const struct sockaddr *addr, unsigned int len)

    int getnameinfo (const struct sockaddr * sa,
                            socklen_t salen, char * host,
                            socklen_t hostlen, char * serv,
                            socklen_t servlen, unsigned int flags)

    struct hostent *gethostbyaddr (const void *addr, socklen_t len,
                                                          int type)

    OS X:

    int     connect __P((int, const struct sockaddr *, socklen_t));

    int             getnameinfo(const struct sockaddr *, socklen_t, char *,
    size_t, char *, size_t, int);

    struct hostent  *gethostbyaddr(const char *, int, int);

    Any possibility of getting a workaround? I'm just an aging Perl hacker, don't know enough C to have a go at it myself... but I can test. :)

    • netcreature

      Let's say you fixed prototypes.
      Anyway, it won't work on OSX as is...

      Here is why:
      proxychains uses shared object to intercept TCP/DNS related libc calls.
      the object is loaded by dynamic linker (LD_PRELOAD) which is different on OSX.

      There is more work to do for OSX, beyond prototypes.

    • OK, it's an LD_PRELOADer. Thanks - if anybody wants to test an OS X port, just contact me.

      I'd like to test an OS X port. my email is

    • I also cannot get a compile to work on OS X (Leopard 10.5). Please send help to craig (AT) Many thanks, Craig

    With a few minor tweaks ProxyChains does work on OS X (at least 10.6.2).  It's not pretty but I've posted a patch with my mods that work for me here:


  • Anonymous

    Before it disappears completely from the net, here is the info on how to patch:

    ProxyChains for Mac OS X patch.

    This patch works against the ProxyChains 3.1 source, which you can get at

    I've tested this on OS X 10.6.2 ONLY. I have no idea if this will work on other versions.

    Patch for OS X: proxychains-3.1_osx.diff. From the directory above your source tree, apply with

    patch -p1 < proxychains-3.1_osx.diff

    I've setup the proxychains script to run from the source tree, like so:

    cd proxychains-3.1
    cd proxychains

    If you want to run it from somewhere else, copy proxychains-3.1/proxychains/.libs/libproxychains.3.0.0.dylib to wherever you want it and modify the proxychains and proxyresolv scripts with the appropriate path.

    proxyresolv is still a bit iffy, best to use IP addresses.

    To make this working on Mac OS X (I used 10.4, should be the same everywhere), you'll need to move the libraries to a good path for the dynamic libraries (they are wrongly installed in /lib), i chose /usr/local/bin:

    sudo mv /lib/libproxychains.* /usr/local/lib/

    and make sure it's listed in your DYLD_LIBRARY_PATH


  • bgt

    Quick update: It's been awhile since I used this, but fired it up today and noticed I was getting intermittent "dyld: could not load inserted library" errors.  This was because the library is building x86_64 by default and I have a lot of tools still built with i386.

    I've posted a change to the patch that builds a universal (i386 + x86_64) binary so both architectures are supported by default. The only change is adding  "-arch i386 -arch x86_64" to CFLAGS in the makefile.
