[Mono-dev] Problems cross compiling Mono itself for ARM with uClibc

[freaky001 at gmx.net]

Hello,

I've tested my gcc with a sample program (a kind of "hello world"), but it works fine. It compiles the source and I get a executable file, which I can run on my ARM-Platform.

What I've done (as user:root, in the directory /usr/local/mono-1.2.6):
# export CC=arm-linux-gcc (it is available in my env - see previous posting)
# ./configure --with-glib=embedded (because I'd like to use the uClibs)

I also tried to configure and make mono 1.2.6 with the compiler for my native architecture (i386) - it works fine too.

I think the problem is located in the message: "configure: error: C compiler cannot create executables".

I don't know what to do. I really need help!
