I got an Error while comiling Intel CilkPlus on CentOS 7.
I can post my config.log (was just a bit too big for this post - if it is usefull I will post it)
And here the last lines of the console output:
checking for C++ compiler default output file name... a.out
checking whether the C++ compiler works... configure: error: in `/home/johannes/b-gcc/x86_64-unknown-linux-gnu/32/libcilkrts':
configure: error: cannot run C++ compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
make[1]: *** [configure-target-libcilkrts] Fehler 1
make[1]: Leaving directory `/home/johannes/b-gcc'
make: *** [all] Fehler 2
Can anyone help me? I just don't know how to fix this.
It looks like the C++ compiler was not build (or not build properly). Can you please post the command you used (along with the tags) you used to configure the compiler?

I'm doing some experiment on rpi4, and trying to reproduce this kernel module from github https://github.com/sysprog21/dont-trace on my rpi4. I encounter this problem:
make -C /lib/modules/`uname -r`/build M=/home/ubuntu/dont-trace modules
make[1]: Entering directory '/usr/src/linux-headers-5.15.65-rt49-preemptrt-full-raspi'
warning: the compiler differs from the one used to build the kernel
The kernel was built by: aarch64-linux-gnu-gcc (Debian 10.2.1-6) 10.2.1 20210110
You are using: gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0

The kernel here is cross-compiled from x86 server and do show above. I was wondering how to solve this problem & what's the root cause. I can make it on x86 server. It should be something fundamental knowledge I don't understand. Thks!
it seems work this time
My solution might be a bit workaround, but it works. I follow the clues /bin/sh: 1: scripts/basic/fixdep: Exec format error. So I copy the source code to local raspberry pi, and make modules_prepare to construct complete /scripts, then move it into /lib/modules/`uname -r\`/build. It remain the gcc version warning, but work properly.
I am having some issues cross-compiling a module for the Raspberry Pi 4.
The compiler used is: aarch64-linux-gnu-.
The kernel used is: linux-5.10.42
And the error during compilation is as follows:
make -C /opt/linux-5.10.42 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- M=/home/x/build/linux-driver-gpio-customled modules
make[1]: Entering directory '/opt/linux-5.10.42'

make[1]: Leaving directory '/opt/linux-5.10.42'
make: *** [Makefile:5: default] Error 2
So my question is as follows: Where should this file asm/types.h come from? To my knowledge it should be included in the kernel arch/arm64/include/asm/ subdirectory. But it's not. Other architectures, namely x86 have it.
Is there another way to build a module without including linux/module.h that i'm not aware of?
Any help is greatly appreciated.
Got it!
The files are autogenerated, there is a handy make command used to prepare the build environment for out-of-tree kernel modules. What I did was run
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- modules_prepare
inside the kernel source.
Hope this helps someone with not spending time on such a simple mistake.
Currently I have GCC 5.4.0-6 installed on my Ubuntu 16.04.4 machine. However nvcc wants me to use 5.3, so I am trying to install that version as well. I did this by:
1. downloading gcc-5.3.0.tar.gz
2. extracting it to ~/Documents/libraryDownloads/GCC-5/gcc-5.3.0
3. creating the folder ~/Documents/libraryDownloads/GCC-5/gcc-build
4. In ~/Documents/libraryDownloads/GCC-5/gcc-5.3.0 I used the command ./contrib/download_prerequisites.
5. In ~/Documents/libraryDownloads/GCC-5/gcc-build I used the command ./../gcc-5.3.0/configure --enable-multilib
6. and finally in ~/Documents/libraryDownloads/GCC-5/gcc-build I used the command make
The make-process rand for a short while and then ended with the following error:
checking whether the gcc -m32 linker (ld -m elf_x86_64 -m elf_i386) supports shared libraries... yes
checking whether -lc should be explicitly linked in... no
checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

As far as I know, I have all prerequisites installed and I am doing all this in a separate build folder as recommended. I tried searching for error: Link tests are not allowed after GCC_NO_EXECUTABLES., but I couldn't find anyone with similar problems. Does anyone know what could be the cause of this error?
I am trying to compile a gcc from source since I cannot use yum, apt-get and so forth. My steps are simple:
-I download the source GCC (I tried gcc-4.8.4 and gcc-5.3.0) in my pc and I used:
./contrib/download_prerequisites
-After this, I send this my gcc source file to my system using powerPC y Linux.
mkdir objdir
cd objdir
../gcc-4.6.2/configure --prefix=/usr --enable-languages=c,c++,fortran,go
make
I have got the next error:

Any idea about what it is going wrong?
Best regards
Some advice: first, compile (notably for learning purposes) something simpler than GCC, e.g. GNU make if you never compiled GNU stuff from source code.
Then compile a recent GCC (so 5.3 in january 2016) - building issues would be the same with 4.8, and GCC 5 is better! You need the gcc & libc-dev & g++ & libstdc++-dev for your host machine (the one running your future cross-compiler). I am not sure your --prefix=/usr is a good idea. Consider perhaps a --program-suffix=-mine option (otherwise, your system's /usr/bin/gcc could be overwritten, which you don't want to happen)
You could leave the default --prefix=/usr/local and later add appropriately /usr/local/bin/ into your PATH
I'm trying to build LLVM and clang on my machine (Ubuntu 12.04). I followed the instructions on http://clang.llvm.org/get_started.html up to step 6 (build LLVM and clang). When I make, I get a whole load of warnings about potentially incompatibly plugin versions (to do with dragonegg?). But the whole thing fails with these messages:
llvm[2]: Linking Debug+Asserts executable llvm-tblgen
/usr/bin/ld: /home/peter/llvm/build/Debug+Asserts/bin/llvm-tblgen: hidden symbol `llvm::Type::~Type()' isn't defined
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status

make[1]: *** [TableGen/.makeall] Error 2
make[1]: Leaving directory `/home/peter/llvm/build/utils'

So any help you could give me would be really helpful.
Thanks
I ended up deleting the llvm folder and checking everything out again, and it worked, so I'm just putting it down to bad timing.
You may want to use the existing LLVM packages, as provided by your distributions.
This askubuntu question about LLVM 3.1 could be relevant.
And you should at least do apt-get build-dep llvm-3.1-dev to ensure all dependencies are available.
You could also ask help on some LLVM related mailing list.
