Can't compile boost 1.50.0 under Cygwin on Windows 7 64-bit

Question

I am trying to compile boost 1.50.0 under Cygwin on Windows 7 64-bit.

I run the command:

./bootstrap.sh –prefix=boost/

and I get back:

Building Boost.Build engine with toolset gcc...
Failed to build Boost.Build build engine
Consult 'bootstrap.log' for more details

Here is the log:

###

./bootstrap/jam0 -f build.jam --toolset=gcc --toolset-root= clean
./build.sh: line 13:  8144 Segmentation fault      $@

What could be the problem? How to solve it?

Answer 1

The error makes it evident that the cygwin_conv_to_win32_path is deprecated.

function.c:653:13: warning: ‘cygwin_conv_to_win32_path’ is deprecated (declared at /usr/include/sys/cygwin.h:36) [-Wdeprecated-declarations]

History: The function cygwin_conv_to_win32_path was supported in Cygwin 1.x and was deprecated in 2.x versions. The 2.x provides the replacement API cygwin_conv_path

How to fix it? Add definition for these deprecated methods as below, and it should resolve the issue( I did the same and was able to build boost library on cygwin)

void cygwin_conv_to_win32_path(const char *posix, char * win32)
{
    /* Get the size */
    ssize_t size = cygwin_conv_path( CCP_POSIX_TO_WIN_A, posix, NULL, 0);
    cygwin_conv_path( CCP_POSIX_TO_WIN_A, posix, win32, size);
}

void cygwin_conv_to_posix_path (const char *win32, char * posix)
{
    /* Get the size */
    ssize_t size = cygwin_conv_path( CCP_WIN_A_TO_POSIX, win32, NULL, 0);
    cygwin_conv_path(  CCP_WIN_A_TO_POSIX , win32, posix, size);
}
