Compilation issues on Linux

[hcOnel]

Hi, As instructed, I modify the compilers in the Makefile as the following:

FCOMPILER = gfortran-11
CCOMPILER = g++-11
LGFORTRAN = #-L/usr/lib/gcc/x86_64-linux-gnu/11/ -I/usr/lib/gcc/x86_64-linux-gnu/11/

and run make as:

make OS=LINUX

I get the following output with errors:

make COMPILE;
make[1]: Entering directory '/home/hconel/WindFLO/src'
gfortran-11 -x f95-cpp-input -g -fcheck=all -fbacktrace -fdec-math -fPIC  -lstdc++ -c WindFLO_f.f90

Is this caused by the compiler version I'm using? Thanks in advance.

[EtorArza]

Hey @hcOnel, I was able to solve this issue by using a earlier version of the repo. In an earlier version, you compile after you cd to the release directory with the command make OS=LINUX MAIN=main.

[hcOnel]

@EtorArza thanks for your suggestion. By changing the definitions as follows:

FCOMPILER = gfortran-10
CCOMPILER = g++-10
LGFORTRAN = -L/usr/lib/gcc/x86_64-linux-gnu/10/ -I/usr/lib/gcc/x86_64-linux-gnu/10/

I've managed to advance up to CREATE_LIB. But now, I'm getting numerous multiple definition and first defined here messages. My make log is as follows (I've trimmed most of the definition messages to shorten it)

[EtorArza]

Yeah, I also get this error when compiling the current version in linux. I managed to make it work by using an earlier version.

The only release I see is this one: https://github.com/sohailreddy/WindFLO/releases/tag/v1.0.0 Is the version you've mentioned older? Can you share it?

[EtorArza]

I think the version in the other branch should work: https://github.com/sohailreddy/WindFLO/tree/WindFLO-v2.0.0

it has the release folder I mentioned and compiles with make OS=LINUX MAIN=main once you cd release. Let me know if it works. To be specific, I am using the version in https://github.com/JudithEtxebarrieta/OPTECOT/tree/main/WindFLO but I think we took the code from the branch https://github.com/sohailreddy/WindFLO/tree/WindFLO-v2.0.0.

Apparently there were some issues with using gcc10 ++ I pushed a fix and tested with gcc10, 11 and 13 Can you try the latest master (with gcc11) and let me know if you are able to compile it.

I've downloaded the latest master branch and tried compiling it with g++-10 and g++-11. I get the same multiple definition warnings and the error as before:

With g++-10:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/libgcc.a(generic-morestack.o): in function `__morestack_fail':
(.text+0x0): multiple definition of `__morestack_fail'; /usr/lib/gcc/x86_64-linux-gnu/10/libgcc.a(generic-morestack.o):(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:110: CREATE_LIB] Error 1
make: *** [Makefile:52: BUILD] Error 2

With g++-11:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/11/libgcc.a(generic-morestack.o): in function `__morestack_fail':
(.text+0x0): multiple definition of `__morestack_fail'; /usr/lib/gcc/x86_64-linux-gnu/11/libgcc.a(generic-morestack.o):(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:110: CREATE_LIB] Error 1
make: *** [Makefile:52: BUILD] Error 2

(you said gcc but I guess you meant g++?)

I'm on Ubuntu 22.04 and the complete make log is attached: log.make.txt Can you please suggest a specific Makefile configuration? I can't pinpoint my mistake.

Note: I've tried compiling with an older version of GCC (gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0) on Ubuntu 18.04 and got this message after "first defined here" messages:
