Fwd: Installing AENet

[Zhenling Wang]

Dear AENet Community,

I am very sorry to disturb you for such a rookie problem on installing AENet but when I make the file it goes like this:

(base) [wangzl@pu239 src]$ make -f makefiles/Makefile.gfortran_openblas_serial
...
/usr/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status
make: *** [../bin/generate.x] Error 1

But the libgfortran.so can be found after I set a soft link to libgfortran.so.3.0.0, as when I run ld:

(base) [wangzl@pu239 src]$ ld -lgfortran --verbose

...
attempt to open /usr/x86_64-redhat-linux/lib64/libgfortran.so failed
attempt to open /usr/x86_64-redhat-linux/lib64/libgfortran.a failed
attempt to open /usr/lib64/libgfortran.so succeeded

...

Do you have any idea where the problem is?

Many thanks in advance,

Zhenling Wang

Dear Zhenling Wang,

This seems to be a GNU Fortran installation issue and not directly related to aenet. 

Have you been able to use gfortran to build other software?

Best,

Nong

Dear Zhenling Wang,

try replacing "-static-libgfortran" with "-lgfortran" in the corresponding makefile.

Some distributions do not install static libraries.

Best regards,

Maxi

Dear all,

Thanks for you quick and working suggestions. I installed a static library version of gfortran and the problem is solved.

Again, thanks for you time and advice,

With best wishes,

Zhenling

Dear all,

When I tried to go through the example, I executed the generate.x (gfortran, openBLAS, serial version) like

$ generate.x generate.in > generate.out

but the program stops with a blank generate.out file giving 

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

Segmentation fault

Do you have any idea why this might happen? I am quite sure that the memory is enough for this program.

Many thanks in advance,

Zhenling

Hey Zhenling, 

Were you able to figure out the issue? I think It has to do with memory, but I am not able to figure out hoe to fix. Please let me know if you found a solution.
