Hello, I am building a cross compiler (linux 32 bits -> windows 32 bits). I have compiled and installed: - binutils-2.24.51 - gcc-4.9.1 (with mingwrt-4.0.3.1 and w32api-4.0.3.1 headers) But when I try to configure the w32api library, I got an error: $ ./configure --prefix=/usr/i686-pc-mingw32 --build=`./config.guess` --host=i686-pc-mingw32 --disable-nls bash: ./config.guess: No such file or directory configure: WARNING: unrecognized options: --disable-nls configure: WARNING: if you wanted to set the --build type, don't use --host. If a cross compiler is detected then cross compile mode will be used checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-mingw32 checking target system type... i686-pc-mingw32 checking for i686-pc-mingw32-gcc... i686-pc-mingw32-gcc checking whether the C compiler works... no configure: error: in `/tmp/build/w32api-4.0.3-1.mingw32-src': configure: error: C compiler cannot create executables See `config.log' for more details As you can see, there is a missing "config.guess" file in the archive. Also, the "--disable-nls" option is not available. Maybe it can explain why the C compiler is recognize by the configure script as not working. Do you have any idea why I am unable to compile this w32api please? Thank you. Best regards.
