Hello everyone !
Until now, I was a happy Linux user. Sadly my new laptop's hardware is not yet supported by current desktop distros (I don't call support the current choice between a black back-lit screen and hanged computer at X startup on one hand, and marvelous 800x600 resolution on a wide screen on the other hand), so I'm more or less forced to get used to Windows 7 at the moment.
I hence installed Cygwin with a basic development setup, and successfully built my cross-compiling GCC and binutils. However, when it comes to building Bochs, configure crashes with the error message "configure:2775: error: C compiler cannot create executables"
Needless to say, this is just plain stupid. If GCC couldn't create executables, my builds of GCC and binutils would have failed. Moreover, if I try to write a very simple C program (int main() { return 0; }) and compile it with GCC, it just works.
Here is the config.log. Can somebody who is more experienced with Cygwin help me ?
Code:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was
generated by GNU Autoconf 2.61. Invocation command line was
$ ./configure --with-win32 --enable-smp --enable-x86-64 --enable-vmx --enable-long-phy-address --enable-sb16=dummy --enable-ne2000 --enable-vbe --enable-clgd54xx --enable-all-optimizations --enable-debugger --enable-pci --enable-usb --enable-usb-ohci
