I use this command->
aarch64-linux-gnu-gcc -i ok.c
to see the output of the prepossesses file
But it gives me error->
aarch64-linux-gnu-gcc: error: unrecognized command line option ‘-i’
I use both native and cross compiler(gcc and aarch64-linux-gnu) but both produces same result, the --help command show where there is no -i command at any compiler,
I find this command in "Advanced C and C++ Compiling - 2014 by Milan Stevanovic" book.
My os is Ubuntu - 20.04.2 LTS
Compiler version : gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0 and
aarch64-linux-gnu-gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

I'm trying to install Quantum ESPRESSO on my computer and have run into an issue when using the ./configure command in the unpacked directory.
$ ./configure

See `config.log' for more details
I just updated to macOS Monterey and have GNU Fortran (Homebrew GCC 11.2.0_3) 11.2.0 installed.
When trying to debug this, I looked at the config.log file and looked at similar googled questions. They all point me to updating or reinstalling things, like gcc, which I subsequently did.
Does the problem have to do with this:
$ gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Target: x86_64-apple-darwin21.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
I can see that the version is 4.2.1, but I'm unaware of what Apple clang is. Is it a PATH issue?
I'd appreciate any help.
P.S. Please choose to be kind in responses.
Here is part of the config.log:

I had the same issue and I solved by doing the following:
Removing the old tools
($ sudo rm -rf /Library/Developer/CommandLineTools).
Installing xcode command line tools again
($ xcode-select --install).

How to update Xcode from command line
My CentOS 7 machine has a default GCC version of 4.8.5. I want to use a higher version of GCC. So, I executed the following steps in a terminal:
sudo yum install centos-release-scl
sudo yum install devtoolset-10-gcc*
scl enable devtoolset-10 bash
After performing the steps, my GCC is now 10.2.1. I then launched Eclipse CDT (10.2.0) through the terminal. Upon enabling C++20 in Eclipse, I tried to compile a simple "hello world" code, but I received the following error in the Eclipse console:
g++ -std=c++2a -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/dummy2.d" -MT"src/dummy2.o" -o "src/dummy2.o" "../src/dummy2.cpp"
g++: error: unrecognized command line option ‘-std=c++2a’
make: *** [src/dummy2.o] Error 1
"make all" terminated with exit code 2. Build might be incomplete.
My system PATH variable has the following directory as its first entry: /opt/rh/devtoolset-10/root/usr/bin. So, I don't know why my Eclipse is still using the old GCC 4.8.5. How do I adjust my Eclipse settings so that I am able to compile higher versions of C++ in CentOS 7?
I am trying to cross-compile opencv 4.0/3.4 for a Tinker Board - ARM-based processor — the Rockchip RK3288
I am using Ubuntu 18.04 as host machine.
I pretty much followed everything mentioned here.
But when I try the cmake using below:
mike#mike-laptop:~/opencv-3.4.5/build$ cmake -DCMAKE_TOOLCHAIN_FILE=../platforms/linux/arm-gnueabi.toolchain.cmake ../ I am getting the below error:
Compiling the CXX compiler identification source file "CMakeCXXCompilerId.cpp" failed. Compiler: /usr/bin/c++ Build flags: -mthumb;;-fdata-sections;-Wa,--noexecstack;-fsigned-char;-Wno-psabi Id flags:

and tons of more messages
I had met the same problem. I try
sudo apt-get install g++-arm-linux-gnueabi
sudo apt-get install g++-arm-linux-gnueabihf
and I solve it.
I hope it will help you!

I'm new and installed linux day ago. Please help me
Run the following commands before the installation:
export CXX=/usr/bin/g++-4.8
export CC=/usr/bin/gcc-4.8
this should set the compiler to gcc-4.8 for the compilation.
so I'm trying to compile a preexisting C++ project with msys and tdm-gcc in Windows. I have done this successfully by installing tdm-gcc (latest version) via the installer, editing MinGW/msys/1.0/etc/fstab to give my tdm-gcc install as the mount location, then running msys to call the configure script, and make.
However, for this project I need to use an old version of tdm-gcc (4.6.1-tdm64-1) for binary compatibility. So I installed the required packages from the tdm-gcc sourceforge site (gcc core, gcc c++, binutils, mingw64-runtime, mingw32-make, libintl, libiconv, all of the version the readme says to use with 4.6.1), extracted to a new directory, and edited fstab to point to their location. Now while executing the configure I get this error: cannot run C compiled programs. The config file reads:

If you meant to cross compile, use `--host'.

I've tried adding the tdm-gcc bin to my path, although I don't think that should matter if fstab is set.
Any advice would be greatly appreciated, thanks.
Try to disable your antivirus.
Worked for me while compiling GStreamer, probably because Avast was deleting the a.exe file.
