I'm using 10.5, and I downloaded the mingw version. How would i update my compiler?
When 10/05 came out there was no compiler available that was working on Windows 7. So this is a known issue. The solution is easy: Un-install C::B
with compiler; download and install the version
without compiler. Then download a recent MinGW, e.g. from here:
http://tdm-gcc.tdragon.net/(it comes with a nice installer btw) and install it wherever you want to (for example in a sub-folder of C::B, called "
MinGW"). Then run C::B, go to the compiler settings, -> select "tool chain executables" and hit "Auto detect" to let C::B find the compiler. This will only work, if you installed MinGW into a standard path's. Alternatively you can also simply point C::B to the folder you installed MinGW into.
BTW: This is roughly the 20th time, this step-by-step instruction is written. In addition you'll find it in the WiKi and the FAQ's of C::B. Have a look there for some more details, if needed.
