Hello, I downloaded the mingw/msys.and I want to use ibsimu so I downloaded the ibsimu and extracted it to a direction as per given instruction but when I tried the make command for ibsimu it shows following error In file included from C:/msys/1.0/home/manje/include/pthread.h:288, from geometry.hpp:48, from epot_field.hpp:47, from epot_field.cpp:44: C:/msys/1.0/home/manje/include/sched.h:152:47: warning: 'cdecl' attribute only applies to function types [-Wattributes] 152 | PTW32_DLLPORT int __cdecl sched_setscheduler (pid_t pid, int policy); | ^~~~~ C:/msys/1.0/home/manje/include/sched.h:152:27: error: definition of 'int sched_setscheduler' is marked 'dllimport' 152 | PTW32_DLLPORT int __cdecl sched_setscheduler (pid_t pid, int policy); | ^~~~~~~~~~~~~~~~~~ C:/msys/1.0/home/manje/include/sched.h:152:47: error: 'pid_t' was not declared in this scope 152 | PTW32_DLLPORT int __cdecl sched_setscheduler (pid_t pid, int policy); | ^~~~~ C:/msys/1.0/home/manje/include/sched.h:152:58: error: expected primary-expression before 'int' 152 | PTW32_DLLPORT int __cdecl sched_setscheduler (pid_t pid, int policy); | ^~~ C:/msys/1.0/home/manje/include/sched.h:152:68: error: expression list treated as compound expression in initializer [-fpermissive] 152 | PTW32_DLLPORT int __cdecl sched_setscheduler (pid_t pid, int policy); | ^ C:/msys/1.0/home/manje/include/sched.h:154:47: warning: 'cdecl' attribute only applies to function types [-Wattributes] 154 | PTW32_DLLPORT int __cdecl sched_getscheduler (pid_t pid); | ^~~~~ C:/msys/1.0/home/manje/include/sched.h:154:27: error: definition of 'int sched_getscheduler' is marked 'dllimport' 154 | PTW32_DLLPORT int __cdecl sched_getscheduler (pid_t pid); | ^~~~~~~~~~~~~~~~~~ C:/msys/1.0/home/manje/include/sched.h:154:47: error: 'pid_t' was not declared in this scope 154 | PTW32_DLLPORT int __cdecl sched_getscheduler (pid_t pid); | ^~~~~ make[2]: *** [epot_field.lo] Error 1 make[2]: Leaving directory `/home/manje/src/libibsimu-1.0.6/src' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/manje/src/libibsimu-1.0.6/src' make: *** [all-recursive] Error 1 and when I tried to run the program it showed that fatal error no such file or directory.I also asked the same to the ibsimu community but they are saying it's because of msys. I am new to it so please guide me. thanks in advance. MANJEET -------------- next part -------------- An HTML attachment was scrubbed...
