cannot compile

[BlueHazzard]

OK, in the CMD type this in this order:

Code Select Expand

set PATH=%PATH%;c:\MinGW\bin
and then

Code Select Expand

mingw32-g++.exe -Wall -fexceptions -g  -c main.cpp -o main.o

The first command will add the MinGW compiler directory to your path so cmd can find the compiler command. The second command will try to build your source without codeblocks, so we can see if something is blocking the compiler.

[Edit:] as soon as you close the cmd you will have to retype the first command.

Still no succes... (see attachment)

There is no file mingw32-g++.exe in the directory c:\MinGW\bin. See my second attachement in my post at 07:17:49 pm

Try

Code Select Expand

mingw32-gcc.exe -Wall -fexceptions -g  -c main.cpp -o main.o

Now Mingw reacts, but still no succes...

[Miguel Gimenez]

It seems G++ is not installed (is an option). Try

Code Select Expand

mingw-get update

and then

Code Select Expand

mingw-get install g++

After this the original command (with mingw32-g++.exe) should work. Probably the compiler executables must be configured again in CB.

Yes, it compiles!

Miguel Gimenez and BlueHazzard, many thanks!

The only thing I don't understand is how it is possible that it compiled when I started the project???

[Miguel Gimenez]

Do you have two MinGW installations?. Probably there was one prior installation of MinGW bundled with Code::Blocks (under Program Files) that was working, and later the automatic detection found the c:\mingw one (as it is the expected path for MinGW).

[wobien]

Where would that Mingw installation bundled with Code::Blocks be? In a subdirectory of the Code::Blocks directory in Program Files?

[Miguel Gimenez]

IIRC it was installed under Program Files\Codeblocks, but I have not installed the bundled version in years.

[wobien]

I don't think I have two MinGW installations. In the Directory where Code::Blocks is installed I can't find anything that looks like MinGW.
