Compile Wt with cygwin (Error in WIOService)

Added by Simon M about 9 years ago

Hi,

I tried to build Wt with cygwin using the docs http://redmine.webtoolkit.eu/projects/wt/wiki/Installing_Wt_on_Cygwin_using_gcc

I use cygwin's:

- gcc 4.9.2

- Boost 1.55 (provided by cygwin)

- cmake 2.8.9

  • make 4.0

However, it fails to compile WIOService (see attached log).

Any help is appreciated, thanks!

So I investigated a little more. Here are the issues I found, when compiling Wt 3.3.3 with Cygwin 1.7.33-2(0.280/5/3):

I used

cmake -DBOOST_PREFIX=/usr -DSSL_PREFIX=/usr/lib -DWT_CPP_11_MODE=-std=c++0x /cygdrive/c/projects/wt-3.3.3/

  • WIOService cannot be compiled, because fd_set is not defined. Removing ADD_DEFINITIONS(-D__USE_W32_SOCKETS) from CMakeLists.txt fixes this, but then I get the following error in wthttp, because it uses Windows sockets:
    In file included from /usr/include/w32api/winsock2.h:56:0, from /cygdrive/cprojects/wt-3.3.3/src/http/Configuration.C:30: /usr/include/w32api/psdk_inc/_fd_types.h:100:2: Warnung: #warning "fd_set and associated macros have been defined in sys/types. This can cause runtime problems with W32 sockets" [-Wcpp] #warning "fd_set and associated macros have been defined in sys/types.

Some more:

  • strcasestr in Request.C is not declared in this scope
  • srand48 in WServer.C is not declared in this scope
  • srand48 in Server.C is not declared in this scope
  • lrand48 in Server.C is not declared in this scope

-DWT_CPP_11_MODE=-std=c++0x defines also __STRICT_ANSI__, so the above functions are not available in Cygwin.

Using cmake -DBOOST_PREFIX=/usr -DSSL_PREFIX=/usr/lib -DWT_CPP_11_MODE=-std=gnu++0x /cygdrive/c/projects/wt-3.3.3/ enables C++11 with GNU extensions and makes the above functions work

* WIOService cannot be compiled, because fd_set is not defined.

I removed ADD_DEFINITIONS(-D__USE_W32_SOCKETS) from CMakeLists.txt and replaced

#ifdef __CYGWIN__
#include <winsock2.h> // for gethostname()
#endif

with

#ifdef __USE_W32_SOCKETS
#include <winsock2.h> // for gethostname()
#endif

in src/http/Configuration.C

* strcasestr in Request.C is not declared in this scope

I added

#undef HAVE_STRCASECMP
#undef HAVE_STRCASESTR

in src/http/Request.C

So I am able to compile Wt with Cygwin, but I am not sure yet, if these changes are correct.

Any help is appreciated, thanks!
