I have some FORTRAN code that I want to compile with F2PY. The code is as follows:
C FILE: FTYPE.F
SUBROUTINE FOO(N)
INTEGER N
Cf2py integer optional,intent(in) :: n = 13
REAL A,X
COMMON /DATA/ A,X(3)
PRINT*, "abc"
END
C END OF FTYPE.F
When I run the following command from Powershell:
f2py -c .\ftype.f -m ftype --compiler=msvc
I get the following errors:
ftype.o : error LNK2019: unresolved external symbol _gfortran_st_write referenced in function foo_
ftype.o : error LNK2019: unresolved external symbol _gfortran_transfer_character_write referenced in function foo_
ftype.o : error LNK2019: unresolved external symbol _gfortran_st_write_done referenced in function foo_
.\ftype.pyd : fatal error LNK1120: 3 unresolved externals
Based on other answers I have seen here, I feel that I may not be linking to a required library. Here is the entire output:

When I comment the PRINT statement in the FORTRAN code, there is no error, and the code compiles.
I am using GNU Fortran (GCC) 6.4.0. I am using Python 2.7.14 :: Anaconda custom (64-bit). I think I am using Visual C++ for Python. My operating system is Windows 10.
Thanks for the help!
I found a solution that works for me, based on the comments above.
I installed MinGW, using the following instructions and settings for Windows
f2py import Fortran code in Python
I ran the following command in PowerShell:
f2py -c ftype.f -m ftype --compiler=mingw32
I ran the following command in python:
import ftype
ftype.foo(5)
I got the following output:
abc
Below is the entire trace, if you are curious. Overall, I think having all the tools from one place (MinGW) might have helped, as in Iguananaut's comment above (Thank you!).
Thank you all for the help!

I'm trying to build the simplest OpenMP or OpenACC C++ program with GPU offload using gcc-10, CUDA 11 on Ubuntu 18.04 and this CMakeLists.txt file (or OpenMP version):
cmake_minimum_required(VERSION 3.18)

find_package(OpenACC REQUIRED)
add_executable(hello main.cpp)
target_compile_options(hello PRIVATE -O3 -fopenacc -foffload=nvptx-none)

The build fails with:

I suspect that a flag defining GPU architecture is missing, but I can't find relevant documentation. Offloading Support in GCC: Compilation options don't have Nvidia example and when I try my best guess -foffload="-arch=sm_75" or -foffload=nvidia-"-arch=sm_75", I get:

Any clues or relevant links will be highly appreciated.
I need to compile OpenCV 2 to test some things and it can only be built with gcc. I tried downloading the oldest NDK in Android Studio which is version 16, however it still tries to use clang. How can I force it to use gcc?

I've downloaded from github and built gcc. After that I've tried to compile a code with OpenMP:
../GCC/build/gcc/xgcc -B./../GCC/build/gcc/ -I./../GCC/build/x86_64-unknown-linux-gnu/libgomp -Wno-write-strings -O3 -Wall -fopenmp -lpng -o mandelbrot-omp mandelbrot-omp.cpp
Then I got the following error message:
xgcc: error: libgomp.spec: No such file or directory
I've checked and found out that libgomp directory contains the libgomp.spec file. The directory is included with -I option. What's wrong?

error: command '/usr/bin/clang'
For whatever reason clang isn't looking in /usr/local/include where it most definitely would find the boost headers. As you can see it is linking all the other dependencies fine. What can I add that so clang will find boost?
On OSX 10.10, nothing fancy happening anywhere. Boost was probably installed by homebrew, but the files are all in /usr/local/include/boost as I'd expect.
Check the output of /usr/bin/clang++ -v some_test_file.cpp but chances are /usr/local/include isn't in the standard search path of the compiler.
You'll need to add -I/usr/local/include to CXXFLAGS or CPPFLAGS or whatever appropriate place in your build script or environment. It seems the python build script is failing to properly detect Boost.
If the above is not true (and /usr/local/include does show up in the output), make sure /usr/local/include/boost/smart_ptr/shared_ptr.hpp exists.
I'm trying to install PyGSL on my computer (64 bit Windows 7), with Python 2.7 and GSL 1.15 installed. I'm pretty much stuck and I would love for some extra help. GSL installed fine, but its the wrapper that's the problem. For some reason I can't build pygsl. Apparently gcc is the problem (got the same problem on another windows machine). Or it could be that pygsl appears to be using a file named AMD64 while my computer is x86. I would love to use the windows binary for pygsl, but it only exists for python 2.5, and my project needs 2.6 or higher. I've used both the windows binary for GSL and built it from source, but I get the same problem either way. I tried copying dlls from GSL into pygsl but that didn't work. Some forums mentioned a file called gsl.dll but I can't seem to find it. I've also tried to use Cygwin and to compile with minGW32 to no avail.
cmds I ran:
python setup.py install
python setup.py build
python setup.py build_ext -i
python setup.py build --compiler=mingw32
Any ideas?? Thanks.
Cheers,
Bereket
Got the same message in Cygwin as in the windows cmd prompt. Error message:

I'm pretty sure now that my GSL install with Cygwin failed / had unresolved dependencies. I'm now trying to install it with visual studio 2010. Here are some good sites for doing that:

Running python setup.py build_ext --inplace does the trick for me.
If this doesn't work let me know. You might need to add an environment variable.
Is your Python 32 or 64? To check open Python and do
