Re: [fpc-pascal] building arm cross compiler on FreeBSD
Perhaps you should build your own binutils, it seems that the version you are using right now does not properly support armv7-m architecture. download ftp://ftp.gnu.org/gnu/binutils/binutils-2.25.1.tar.gz |extract, create an empty directory and do:| || |../binutils-2.25.1/configure --target=arm-none-eabi --disable-multilib --program-prefix=arm-none-eabi-| || |sudo make install will install the tools to /usr/local| || || or try this version from freshports: https://www.freshports.org/devel/gcc-arm-embedded/ It also builds gcc, which of course you do not need.

That's what I guessed from your response. Nevertheless, the message also contained an explicit note of running FreeBSD on his device. I checked it and FreeBSD seems to support the device according to Internet sources indeed. It's up to the original poster to clarify whether he intends to target FreeBSD on his device, or whether he was interested in creating programs for the device without an operating system. > My guess was that the reason he was asking, was that if you do a "make > all CPU_TARGET=arm" at the top level to get an ARM cross-compiler, the > Makefile will default to $(OS_SOURCE)/$(CPU_TARGET), which will indeed > result in complaints about FreeBSD/ARM not being supported if you do it > on FreeBSD. Yes, I think so as well, but it might be exactly the thing he was interested in.

Jonas is right. Compiling a cross compiler with target arm embedded on a system running freebsd. -- Marc Santhoff ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Did the trick, a current version of arm-elf-binutils worked. :) Many thanks to all who contributed.

It compiles it thrice: once more in the end to ensure that the resulting compiler is "stable", in the sense that it generates the same code when compiled with itself as when compiled with a previous release.

Fantastic! Then I can be assured a successful make results in the expected release version!
