Hello, I have a problem cross compiling using autotools for my Raspberry Pi 3. I wrote a server program which runs good with Linux and under windows (compiled with MinGW) on my X86_64 machine. Since there is no configure wrapper for ARM like MinGW has, i use the following configure call: ./configure --host=arm-linux-gnu The Script is failing and the log tells me about bad options "-qverseion" and "-V" in GCC tests. So I removed this Options from the Script by hand. Now it tells me about a missing file called "crt1.o". But i found this file in "/usr/arm-linux-gnu/lib/crt1.o".

So, my question is: Did i miss something?

How do I use the cross compiler with autotools?

Thank you, this did the trick. The shown Path are wrong, or the rpm installed the files in the wrong paths, depends on how you look at it. Now i habe to figure out if i can correct the path in config, or i do a somple symlink on the fs.

Using autotools for this works for others, so the problem should be my configuration. > > How do I use the cross compiler with > > autotools? > In an ideal world, exactly like you did.

I have a very simple configure.ac, no special options, but this deserves a deeper look. > Also make sure NOT to have set CC, CFLAGS etc in your environment. These variables are unset in my Environment because I use autotools for all my Project. These variables are set temporarily by them. Thanks for you advice.
