Build break: iossimulator Mono build fails compiling conditionvariable.c

The Build product step for the iossimulator arm64 Release Mono leg fails to compile src/native/minipal/conditionvariable.c because pthread_cond_timedwait_relative_np is called without a visible declaration under the iOS Simulator SDK. -Wimplicit-function-declaration is an error, so the build breaks and every downstream test leg is skipped.

Failure signature

src/native/minipal/conditionvariable.c:115:17: error: call to undeclared function 'pthread_cond_timedwait_relative_np'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

Build information

  • Pipeline: runtime-extra-platforms (definition 154), branch main
  • Leg: iossimulator arm64 Release Mono, Xcode 26.3.0 / iPhoneSimulator SDK
  • First build it occurred: 1563837
  • Confirmed still failing in follow-up build 1564198

Line 115 of conditionvariable.c calls pthread_cond_timedwait_relative_np guarded by #if HAVE_CLOCK_GETTIME_NSEC_NP; on the current iOS Simulator SDK that symbol is not declared, so the guard admits a call to an undeclared function.

                  Build break: iossimulator Mono build fails compiling conditionvariable.c
                  The Build product step for the iossimulator arm64 Release Mono leg fails to compile src/native/minipal/conditionvariable.c because pthread_cond_timedwait_relative_np is called without a visible declaration under the iOS Simulator SDK. -Wimplicit-function-declaration is an error, so the build breaks and every downstream test leg is skipped.

                              Build break: iossimulator Mono build fails compiling conditionvariable.c
                              The Build product step for the iossimulator arm64 Release Mono leg fails to compile src/native/minipal/conditionvariable.c because pthread_cond_timedwait_relative_np is called without a visible declaration under the iOS Simulator SDK. -Wimplicit-function-declaration is an error, so the build breaks and every downstream test leg is skipped.
                              Failure signature
                              src/native/minipal/conditionvariable.c:115:17: error: call to undeclared function 'pthread_cond_timedwait_relative_np'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

                              • Pipeline: runtime-extra-platforms (definition 154), branch main
                              • Leg: iossimulator arm64 Release Mono, Xcode 26.3.0 / iPhoneSimulator SDK
                              • First build it occurred: 1563837
                              • Confirmed still failing in follow-up build 1564198
                              Line 115 of conditionvariable.c calls pthread_cond_timedwait_relative_np guarded by #if HAVE_CLOCK_GETTIME_NSEC_NP; on the current iOS Simulator SDK that symbol is not declared, so the guard admits a call to an undeclared function.
