error: ‘SA_RESETHAND’ undeclared

[Pierre Trontin]

Hello,

After updating to the new release, I have a problem compiling the portable (ISO C99) source code (_mycase.c) on my supercomputer :

mpicc -Wall -std=c99 -O2 -D_MPI=1 _mycase.c -o mycase.exe -lm

I have the following error :

src/grid/fpe.h:50:18: error: ‘SA_RESETHAND’ undeclared (first use in this function)

I didn't observe this problem with an older version of Basilisk.

My GCC and MPICC versions : 9.4.0

No problem to generate the portable source code _mycase.c

Has anyone ever encountered this difficulty ?

Thank you.

Pierre

Hi Pierre,

Did you try:

mpicc -Wall -std=c99 -D_XOPEN_SOURCE=700 -O2 -D_MPI=1 _mycase.c -o
mycase.exe -lm

Hello Stephane,

It now works fine with option -D_XOPEN_SOURCE=700

Thanks a lot !

Pierre
