Hi,

Re: Safe C functions in IPP file vm_base.c link problems

First, I understand "libcommon.a" must be built. In using "common.xcodeproj", there's a build error:

In file included from /opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/components/common/include/safestring/safe_lib.h:67:

/opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/components/common/include/safestring/safe_mem_lib.h:62:16: error: conflicting types for 'memset_s'

extern errno_t memset_s(void *dest, rsize_t dmax, uint8_t value);

In module 'Darwin' imported from /opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/components/common/include/vm_base.h:32:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/string.h:145:9: note: previous declaration is here

errno_t memset_s(void *__s, rsize_t __smax, int __c, rsize_t __n) __OSX_AVAILABLE_STARTING(__MAC_10_9, __IPHONE_7_0);

Commenting out: extern errno_t memset_s(void *dest, rsize_t dmax, uint8_t value) in "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/string.h" enables a successful build of libcommon.a

Now, when linking, getting this error:

ian$ clang++ src/ipp_resize_mt.cpp -I/opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/include -I/opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/components/common/include -L/opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/lib -lippi -lipps -lippcore -stdlib=libc++ /opt/intel/compilers_and_libraries_2019.5.281/mac/ipp/components/common/build/Release/libcommon.a

Any ideas would be greatly appreciated.

Thanks for looking,

Hello, Ian!

vsctprintf, memcpy_s, strncpy_s and vsnprintf_s are members of stdlib. Did you try to compile and build any other application, for example, a simple "Hello, World!" program?

Best regards,
Ivan Galanin.
