#14 Unspecific casting sigio_handler in examples/notify_group.c
I'm building the 4.11.1 source using the PGI/NVHPC 22.5 compiler
/work/SHARE/Utils/PGI/22.5/Linux_x86_64/22.5/compilers/bin/pgcc -Masmkeyword -g -O0 -noswitcherror -m64 -tp=px -D__thread='' -mp -lpthread -g -Wall -Werror -Wextra -Wno-unused-parameter -I. -I/work/SHARE/Utils/PerfMon2/4.11.1/PGI-22.5/distro/include -DCONFIG_PFMLIB_DEBUG -DCONFIG_PFMLIB_OS_LINUX -g -Wall -Werror -Wextra -Wno-unused-parameter -I. -I/work/SHARE/Utils/PerfMon2/4.11.1/PGI-22.5/distro/perf_examples/../include -DCONFIG_PFMLIB_DEBUG -DCONFIG_PFMLIB_OS_LINUX -I. -D_GNU_SOURCE -pthread -c notify_group.c
and got this error:
"notify_group.c", line 125: error: a value of type "void *" cannot be assigned to an entity of type "void (*)(int, siginfo_t *, void *)"
act.sa_sigaction = (void *)sigio_handler;
^
1 error detected in the compilation of "notify_group.c".
make[1]: *** [/work/SHARE/Utils/PerfMon2/4.11.1/PGI-22.5/distro/perf_examples/../rules.mk:30: notify_group.o] Error 2
make[1]: Leaving directory '/work/SHARE/Utils/PerfMon2/4.11.1/PGI-22.5/distro/perf_examples'
I can fix it with the change
125c125
< act.sa_sigaction = (void *)sigio_handler;
---
> act.sa_sigaction = (void (*)(int, siginfo_t *, void *))sigio_handler;
correspondent with the recommendation in the error-message.
I know that the PGI compilers are stricter than GCC or Intel in terms of language compliance, and expect this change would work with the other compilers as well.
